Configuration options
|
|
================================================================================
|
|
|
|
The main configuration file for GNU social (excepting configurations for
|
|
dependency software) is config.php in your GNU social directory. If you edit any
|
|
other file in the directory, like `lib/default.php` (where most of the defaults
|
|
are defined), you will lose your configuration options in any upgrade, and you
|
|
will wish that you had been more careful.
|
|
|
|
Starting with version 0.9.0, a Web based configuration panel has been added to
|
|
GNU social. The preferred method for changing config options is to use this
|
|
panel.
|
|
|
|
A command-line script, setconfig.php, can be used to set individual
|
|
configuration options. It's in the scripts/ directory.
|
|
|
|
Starting with version 0.7.1, you can put config files in the /etc/GNU social/
|
|
directory on your server, if it exists. Config files will be included in this
|
|
order:
|
|
|
|
* `/etc/GNU social/statusnet.php` - server-wide config
|
|
|
|
* `/etc/GNU social/<servername>.php` - for a virtual host
|
|
|
|
* `/etc/GNU social/<servername>_<pathname>.php` - for a path
|
|
|
|
* `INSTALLDIR/config.php` - for a particular implementation
|
|
|
|
Almost all configuration options are made through a two-dimensional
|
|
associative array, cleverly named $config. A typical configuration
|
|
line will be:
|
|
|
|
$config['section']['option'] = value;
|
|
|
|
For brevity, the following documentation describes each section and
|
|
option.
|
|
|
|
|
|
site
|
|
-------------------------------------------------------------------------------
|
|
|
|
This section is a catch-all for site-wide variables.
|
|
|
|
* `name` (string, required, default "Another GNU social Instance"): the name of
|
|
your site, like 'YourCompany Microblog'.
|
|
|
|
* `server` (string, required, default null): the server part of your site's URLs,
|
|
like 'example.net'.
|
|
|
|
* `path` (string, required, default ''): The path part of your site's URLs, like
|
|
'statusnet' or '' (installed in root).
|
|
|
|
* `fancy` (string, default false): whether or not your site uses fancy URLs (see Fancy URLs
|
|
section above).
|
|
|
|
* `logfile` (string, default './'): full path to a file for GNU social to save
|
|
logging information to. You may want to use this if you don't have access
|
|
to syslog.
|
|
|
|
* `logdebug` (boolean, default false): whether to log additional debug info like
|
|
backtraces on hard errors.
|
|
|
|
* `locale_path` (string, default null): full path to the directory for locale
|
|
data. Unless you store all your locale data in one place, you probably
|
|
don't need to use this.
|
|
|
|
* `language` (string, default "en_us"): default language for your site. Defaults
|
|
to US English. Note that this is overridden if a user is logged in and has
|
|
selected a different language. It is also overridden if the user is NOT
|
|
logged in, but their browser requests a different langauge. Since pretty
|
|
much everybody's browser requests a language, that means that changing
|
|
this setting has little or no effect in practice.
|
|
|
|
* `languages` (array, default null): A list of languages supported on your site.
|
|
Typically you'd only change this if you wanted to disable support for one or
|
|
another language:
|
|
|
|
"unset($config['site']['languages']['de'])" will disable
|
|
support for German.
|
|
|
|
* `theme` (string, default 'default'): Theme for your site (see Theme section).
|
|
Two themes are provided by default: 'default' and 'stoica' (the one used by
|
|
Identi.ca). It's appreciated if you don't use the 'stoica' theme except as
|
|
the basis for your own.
|
|
|
|
* `email` (string, required): contact email address for your site. By default,
|
|
it's extracted from your Web server environment; you may want to customize it.
|
|
|
|
* `broughtbyurl` (string, default null): name of an organization or individual
|
|
who provides the service. Each page will include a link to this name in the
|
|
footer. A good way to link to the blog, forum, wiki, corporate portal, or
|
|
whoever is making the service available.
|
|
|
|
* `broughtby` (string, default null): text used for the "brought by" link.
|
|
|
|
* `timezone` (string, default 'UTC'): default timezone for message display. Users
|
|
can set their own time zone. Defaults to 'UTC', which is a pretty good
|
|
default.
|
|
|
|
* `closed` (boolean, default false): If set to 'true', will disallow registration
|
|
on your site. This is a cheap way to restrict accounts to only one
|
|
individual or group; just register the accounts you want on the service,
|
|
*then* set this variable to 'true'.
|
|
|
|
* `inviteonly` (boolean, default false): If set to 'true', will only allow
|
|
registration if the user was invited by an existing user.
|
|
|
|
* `private` (boolean, default false): If set to 'true', anonymous users will be
|
|
redirected to the 'login' page. Also, API methods that normally require no
|
|
authentication will require it. Note that this does not turn off
|
|
registration; use 'closed' or 'inviteonly' for the behaviour you want.
|
|
|
|
* `notice` (string, default null): A plain string that will appear on every
|
|
page. A good place to put introductory information about your service, or
|
|
info about upgrades and outages, or other community info. Any HTML will be
|
|
escaped.
|
|
|
|
* `logo` (string, default null): URL of an image file to use as the logo for the
|
|
site. Overrides the logo in the theme, if any.
|
|
|
|
* `ssllogo` (string, default null): URL of an image file to use as the logo on
|
|
SSL pages. If unset, theme logo is used instead.
|
|
|
|
* `ssl` (enum['always','sometimes','never'], default 'never'): Whether to use SSL
|
|
and https:// URLs for some or all pages.
|
|
|
|
Possible values are 'always' (use it for all pages), 'never' (don't use it
|
|
for any pages), or 'sometimes' (use it for sensitive pages that include
|
|
passwords like login and registration, but not for regular pages).
|
|
|
|
* `sslproxy` (boolean, default false): Whether to force GNUsocial to think it
|
|
is HTTPS when the server gives no such information. I.e. when you're using
|
|
a reverse proxy that adds the encryption layer but the webserver that runs
|
|
PHP isn't configured with a key and certificate.
|
|
|
|
* `sslserver` (string, default null): use an alternate server name for SSL URLs,
|
|
like 'secure.example.org'. You should be careful to set cookie parameters
|
|
correctly so that both the SSL server and the "normal" server can access
|
|
the session cookie and preferably other cookies as well.
|
|
|
|
* `dupelimit` (integer, default 60): minimum time allowed for one person to say
|
|
the same thing twice. Default 60s. Anything lower is considered a user or
|
|
UI error.
|
|
|
|
* `textlimit` (integer, default 0): default max size for texts in the site. Can
|
|
be fine-tuned for notices, messages, profile bios and group descriptions.
|
|
Zero indicates no limit.
|
|
|
|
|
|
db
|
|
-------------------------------------------------------------------------------
|
|
|
|
This section is a reference to the configuration options for
|
|
`DB_DataObject` (see
|
|
<http://pear.php.net/manual/en/package.database.db-dataobject.intro-configuration.php>).
|
|
The ones that you may want to set are listed below for clarity.
|
|
|
|
* `database` (string, required, default null): a DSN (Data Source Name) for your
|
|
GNU social database. This is in the format
|
|
'protocol://username:password@hostname/databasename', where 'protocol' is '
|
|
mysql' or 'mysqli' (or possibly 'postgresql', if you really know what
|
|
you're doing), 'username' is the username, 'password' is the password,
|
|
and etc.
|
|
|
|
* `ini_yourdbname` (string, default null): if your database is not named 'statusnet',
|
|
you'll need to set this to point to the location of the statusnet.ini file.
|
|
Note that the real name of your database should go in there, not literally
|
|
'yourdbname'.
|
|
|
|
* `db_driver`(enum['DB','MDB2'], default null): You can try changing this to
|
|
'MDB2' to use the other driver type for DB_DataObject, but note that it
|
|
breaks the OpenID libraries, which only support PEAR::DB.
|
|
|
|
* `quote_identifiers`(boolean, default false): Set this to true if you're using
|
|
postgresql.
|
|
|
|
* `type` (enum["mysql", "postgresql"], default 'mysql'): Used for certain
|
|
database-specific optimization code. Assumes mysql if not set. MySQL also
|
|
covers MySQLi and MariaDB.
|
|
|
|
* `mirror` (array, default null): you can set this to an array of DSNs, in the
|
|
format of the above 'database' value. If it's set, certain read-only
|
|
actions will use a random value out of this array for the database, rather
|
|
than the one in 'database' (actually, 'database' is overwritten). You can
|
|
offload a busy DB server by setting up MySQL replication and adding the
|
|
slaves to this array. Note that if you want some requests to go to the
|
|
'database' (master) server, you'll need to include it in this array, too.
|
|
|
|
* `utf8` (boolean, true): whether to talk to the database in UTF-8 mode. This is
|
|
the default with new installations, but older sites may want to turn it off
|
|
until they get their databases fixed up. See "UTF-8 database" above for
|
|
details.
|
|
|
|
* `schemacheck` (enum["runtime", "script"], default "runtime"): when to let
|
|
plugins check the database schema to add tables or update them. 'runtime'
|
|
can be costly (plugins check the schema on every hit, adding potentially
|
|
several db queries, some quite long), but not everyone knows how to run a
|
|
script or has the access in their hosting environment to do so. If you can,
|
|
set this to 'script' and run scripts/checkschema.php whenever you install
|
|
or upgrade a plugin.
|
|
|
|
|
|
syslog
|
|
-------------------------------------------------------------------------------
|
|
|
|
By default, GNU social sites log error messages to the syslog facility.
|
|
(You can override this using the 'logfile' parameter described above).
|
|
|
|
* `appname` (string, default `'GNU social'`): The name that GNU social uses to log
|
|
messages. By default it's "GNU social", but if you have more than one
|
|
installation on the server, you may want to change the name for each
|
|
instance so you can track log messages more easily.
|
|
|
|
* `facility` (string, default `'LOG_USER'`): what syslog facility to use. Only set
|
|
this if you know what syslog is and have a good reason to change it.
|
|
|
|
|
|
queue
|
|
-------------------------------------------------------------------------------
|
|
|
|
You can configure the software to queue time-consuming tasks, like
|
|
sending out SMS email or XMPP messages, for off-line processing. See
|
|
'Queues and daemons' above for how to set this up.
|
|
|
|
* `enabled` (boolean, default false): Whether to uses queues.
|
|
|
|
* `daemon` (boolean, default false): Wather to use queuedaemon. False means
|
|
you'll use OpportunisticQM plugin.
|
|
|
|
* `subsystem` (enum["db", "stomp"], default 'db'): Which kind of queueserver to
|
|
use. Values include "db" for our hacked-together database queuing (no
|
|
other server required), "stomp" for a stomp server, and "redis" for a Redis
|
|
server.
|
|
|
|
* `threads` (int): How many queue "threads" (actually processes) to run. Defaults to
|
|
number of cpu cores in unix-like systems or 1 on other OSes.
|
|
|
|
* `items_to_handle` (int): How many items to handle before a daemon process exits.
|
|
Default to unlimited.
|
|
|
|
* `stomp_server` (string, default null): "broker URI" for stomp server.
|
|
Something like "tcp://hostname:61613". More complicated ones are possible;
|
|
see your stomp server's documentation for details.
|
|
|
|
* `queue_basename` (string, default null): a root name to use for queues (stomp
|
|
only). Typically something like '/queue/sitename/' makes sense. If running
|
|
multiple instances on the same server, make sure that either this setting
|
|
or $config['site']['nickname'] are unique for each site to keep them
|
|
separate.
|
|
|
|
* `stomp_username` (string, default null): username for connecting to the stomp
|
|
server.
|
|
|
|
* `stomp_password` (string, default null): password for connecting to the stomp
|
|
server.
|
|
|
|
* `stomp_persistent` (boolean, default true): Keep items across queue server
|
|
restart, if enabled. Note: Under ActiveMQ, the server configuration
|
|
determines if and how persistent storage is actually saved.
|
|
|
|
If using a message queue server other than ActiveMQ, you may
|
|
need to disable this if it does not support persistence.
|
|
|
|
* `stomp_transactions` (boolean, default true): use transactions to aid in error
|
|
detection. A broken transaction will be seen quickly, allowing a message to
|
|
be redelivered immediately if a daemon crashes.
|
|
|
|
If using a message queue server other than ActiveMQ, you may need to
|
|
disable this if it does not support transactions.
|
|
|
|
* `stomp_acks` (boolean, default true): send acknowledgements to aid in flow
|
|
control. An acknowledgement of successful processing tells the server we're
|
|
ready for more and can help keep things moving smoothly.
|
|
|
|
This should *not* be turned off when running with ActiveMQ, (it breaks if
|
|
you do), but if using another message queue server that does not support
|
|
acknowledgements you might need to disable this.
|
|
|
|
* `softlimit` (integer): an absolute or relative "soft memory limit"; daemons
|
|
will restart themselves gracefully when they find they've hit this amount
|
|
of memory usage. Defaults to 90% of PHP's global memory_limit setting.
|
|
|
|
* `inboxes` (boolean, default true): delivery of messages to receiver's inboxes
|
|
can be delayed to queue time for best interactive performance on the
|
|
sender. This may however be annoyingly slow when using the DB queues, so
|
|
you can set this to false if it's causing trouble.
|
|
|
|
* `breakout` (array, default null): for stomp, individual queues are by default
|
|
grouped up for best scalability. If some need to be run by separate daemons,
|
|
etc they can be manually adjusted here.
|
|
|
|
Default will share all queues for all sites within each group.
|
|
Specify as <group>/<queue> or <group>/<queue>/<site>,
|
|
using nickname identifier as site.
|
|
|
|
'main/distrib' separate "distrib" queue covering all sites
|
|
'xmpp/xmppout/mysite' separate "xmppout" queue covering just 'mysite'
|
|
|
|
* `max_retries` (integer, default 10): for stomp, drop messages after N failed
|
|
attempts to process.
|
|
|
|
* `dead_letter_dir` (string, default null): for stomp, optional directory to dump
|
|
data on failed queue processing events after discarding them.
|
|
|
|
* `stomp_no_transactions` (boolean, default false): for stomp, the server does
|
|
not support transactions, so do not try to user them. This is needed for
|
|
http://www.morbidq.com/
|
|
|
|
* `stomp_no_acks` (boolean, default false): for stomp, the server does not
|
|
support acknowledgements so do not try to user them. This is needed for
|
|
http://www.morbidq.com/.
|
|
|
|
|
|
license
|
|
-------------------------------------------------------------------------------
|
|
|
|
The default license to use for your users notices. The default is the
|
|
Creative Commons Attribution 3.0 license, which is probably the right
|
|
choice for any public site. Note that some other servers will not
|
|
accept notices if you apply a stricter license than this.
|
|
|
|
As of 2016, this is largely disregarded in the Fediverse -mb
|
|
|
|
* `type` (enum["cc", "allrightsreserved", "private"], default 'cc'): one of
|
|
'cc' (for Creative Commons licenses), 'allrightsreserved' (default
|
|
copyright), or 'private' (for private and confidential information).
|
|
|
|
* `owner` (string, default 'contributors'): for 'allrightsreserved' or
|
|
'private', an assigned copyright holder (for example, an employer for a
|
|
private site).
|
|
|
|
* `url` (string, default null): URL of the license, used for links.
|
|
|
|
* `title` (string, default null): Title for the license, like 'Creative Commons
|
|
Attribution 3.0'.
|
|
|
|
* `image` (string, default null): URL of a button shown on each page for the
|
|
license.
|
|
|
|
|
|
mail
|
|
-------------------------------------------------------------------------------
|
|
|
|
This is for configuring out-going email. We use PEAR's Mail module,
|
|
see: http://pear.php.net/manual/en/package.mail.mail.factory.php
|
|
|
|
* `backend` (enum["mail", "sendmail", "smtp"], default 'mail'): The backend to
|
|
use for mail. While this defaults to PEAR mail, we recommend SMTP where your
|
|
setup supports it as it is of the three the more difficult one for script
|
|
exploits to abuse (relatively speaking - they all have potential problems.)
|
|
|
|
* `params` (array, default null): if the mail backend requires any parameters,
|
|
you can provide them in an associative array.
|
|
|
|
* `templates_path` (string, default null): alias for `site->mail_path`
|
|
|
|
|
|
nickname
|
|
-------------------------------------------------------------------------------
|
|
|
|
This is for configuring nicknames in the service.
|
|
|
|
* `blacklist` (array, default null): an array of strings for usernames that
|
|
may not be registered. A hard-coded default array exists for strings that
|
|
are used by GNU social (e.g. 'doc', 'main', 'avatar', 'theme') but you may
|
|
want to add others if you have other software installed in a subdirectory
|
|
of GNU social or if you just don't want certain words used as usernames.
|
|
|
|
* `featured` (array, default null): an array of nicknames of 'featured' users of
|
|
the site. Can be useful to draw attention to well-known users, or
|
|
interesting people, or whatever.
|
|
|
|
|
|
avatar
|
|
-------------------------------------------------------------------------------
|
|
|
|
For configuring avatar access.
|
|
|
|
* `dir` (string, default './avatar'): Directory to look for avatar files and to
|
|
put them into. Defaults to avatar subdirectory of install directory; if
|
|
you change it, make sure to change path, too.
|
|
|
|
* `path` (string, 'default './avatar'): Path to avatars. Defaults to path for
|
|
avatar subdirectory, but you can change it if you wish. Note that this will
|
|
be included with the avatar server, too.
|
|
|
|
* `server` (string, default null): If set, defines another server where avatars
|
|
are stored in the root directory. Note that the 'avatar' subdir still has
|
|
to be writeable. You'd typically use this to split HTTP requests on the
|
|
client to speed up page loading, either with another virtual server or
|
|
with an NFS or SAMBA share. Clients typically only make 2 connections to a
|
|
single server at a time
|
|
<https://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.4>,
|
|
so this can parallelize the job.
|
|
|
|
* `ssl` (boolean, default null): Whether to access avatars using HTTPS. Defaults
|
|
to null, meaning to guess based on site-wide SSL settings.
|
|
|
|
|
|
public
|
|
-------------------------------------------------------------------------------
|
|
|
|
For configuring the public stream.
|
|
|
|
* `localonly` (boolean, default true): If set to true, only messages posted by
|
|
users of this service (rather than other services, filtered through
|
|
OStatus) are shown in the public stream. Default true.
|
|
|
|
* `blacklist` (array, default null): An array of IDs of users to hide from the
|
|
public stream. Useful if you have someone making excessive Twitterfeed
|
|
posts to the site, other kinds of automated posts, testing bots, etc.
|
|
|
|
* `autosource` (array, default null): Sources of notices that are from automatic
|
|
posters, and thus should be kept off the public timeline.
|
|
|
|
|
|
theme
|
|
-------------------------------------------------------------------------------
|
|
|
|
* `server` (string, default null): Like avatars, you can speed up page loading
|
|
by pointing the theme file lookup to another server (virtual or real).
|
|
The default of null will use the same server as PA.
|
|
|
|
* `dir` (string, default "./themes"): Directory where theme files are stored.
|
|
Used to determine whether to show parts of a theme file. Defaults to the
|
|
theme subdirectory of the install directory.
|
|
|
|
* `path` (string, default null): Path part of theme URLs, before the theme name. Relative to the
|
|
theme server. It may make sense to change this path when upgrading,
|
|
(using version numbers as the path) to make sure that all files are
|
|
reloaded by caching clients or proxies. Defaults to null,
|
|
which means to use the site path + '/theme'.
|
|
|
|
* `ssl` (boolean, default null): Whether to use SSL for theme elements. Default
|
|
is null, which means guess based on site SSL settings.
|
|
|
|
* `sslserver` (string, default null): SSL server to use when page is
|
|
HTTPS-encrypted. If unspecified, site ssl server and so on will be used.
|
|
|
|
* `sslpath` (string, default null): If sslserver if defined, path to use when
|
|
page is HTTPS-encrypted.
|
|
|
|
|
|
javascript
|
|
-------------------------------------------------------------------------------
|
|
|
|
* `server` (string, default null): You can speed up page loading by pointing the
|
|
theme file lookup to another server (virtual or real). Defaults to NULL,
|
|
meaning to use the site server.
|
|
|
|
* `path` (string default null): Path part of Javascript URLs. Defaults to null,
|
|
which means to use the site path + '/js/'.
|
|
|
|
* `ssl` (boolean, default null): Whether to use SSL for JavaScript files.
|
|
Default is null, which means guess based on site SSL settings.
|
|
|
|
* `sslserver` (string, default null): SSL server to use when page is HTTPS-
|
|
encrypted. If unspecified, site ssl server and so on will be used.
|
|
|
|
* `sslpath` (string, default null): If sslserver if defined, path to use when
|
|
page is HTTPS-encrypted.
|
|
|
|
* `bustframes` (boolean, default true): If true, all web pages will break out of
|
|
framesets. If false, can comfortably live in a frame or iframe... probably.
|
|
|
|
|
|
xmpp
|
|
-------------------------------------------------------------------------------
|
|
|
|
For configuring the XMPP sub-system.
|
|
|
|
* `enabled` (boolean, default false): Whether to accept and send messages by
|
|
XMPP. Default false.
|
|
|
|
* `server` (string, default null): Server part of XMPP ID for update user.
|
|
|
|
* `port` (integer, default 5222): Connection port for clients.
|
|
|
|
* `user` (string, default null): Username for the client connection. Users will
|
|
receive messages from 'user'@'server'.
|
|
|
|
* `resource`: a unique identifier for the connection to the server. This
|
|
is actually used as a prefix for each XMPP component in the system.
|
|
|
|
* `password`: password for the user account.
|
|
|
|
* `host`: some XMPP domains are served by machines with a different
|
|
hostname. Set this to the correct hostname if that's the
|
|
case with your server.
|
|
|
|
* `encryption`: Whether to encrypt the connection between GNU social and the
|
|
XMPP server. Defaults to true, but you can get
|
|
considerably better performance turning it off if you're
|
|
connecting to a server on the same machine or on a
|
|
protected network.
|
|
|
|
* `debug`: if turned on, this will make the XMPP library blurt out all of
|
|
the incoming and outgoing messages as XML stanzas. Use as a
|
|
last resort, and never turn it on if you don't have queues
|
|
enabled, since it will spit out sensitive data to the browser.
|
|
|
|
* `public`: an array of JIDs to send _all_ notices to. This is useful for
|
|
participating in third-party search and archiving services.
|
|
|
|
|
|
invite
|
|
-------------------------------------------------------------------------------
|
|

|
|
-------------------------------------------------------------------------------
|
|
|
|
Miscellaneous tagging stuff.
|
|
|
|
* `dropoff`: Decay factor for tag listing, in seconds.
|
|
Defaults to exponential decay over ten days; you can twiddle
|
|
with it to try and get better results for your site.
|
|
|
|
|
|
popular
|
|
-------------------------------------------------------------------------------
|
|
|
|
Settings for the "popular" section of the site.
|
|
|
|

with it to try and get better results for your site.
|
|
|
|
|
|
daemon
|
|
-------------------------------------------------------------------------------
|
|
|
|
For daemon processes.
|
|
|
|
* `piddir`: directory that daemon processes should write their PID file
|
|
(process ID) to. Defaults to /var/run/, which is where this
|
|
stuff should usually go on Unix-ish systems.
|
|
|
|
* `user`: If set, the daemons will try to change their effective user ID
|
|
to this user before running. Probably a good idea, especially if
|
|
you start the daemons as root. Note: user name, like 'daemon',
|
|
not 1001.
|
|
|
|
* `group`: If set, the daemons will try to change their effective group ID
|
|
to this named group. Again, a name, not a numerical ID.
|
|
|

|
|
-------------------------------------------------------------------------------
|
|
|
|
For post-by-email.
|
|
|
|
* `enabled`: Whether to enable post-by-email. Defaults to true. You will
|
|
also need to set up maildaemon.php.
|
|
|
|
|
|
sms
|
|
-------------------------------------------------------------------------------
|
|
|
|
For SMS integration.
|
|
|
|
* `enabled`: Whether to enable SMS integration. Defaults to true. Queues
|
|
should also be enabled.
|
|
|

inboxes
|
|
-------------------------------------------------------------------------------

|
|
|
|
* `enabled`: No longer used. If you set this to something other than true,
|
|
GNU social will no longer run.
|
|
|
|
|
|
throttle
|
|
-------------------------------------------------------------------------------
|
|
|
|
For notice-posting throttles.
|
|
|
|
* `enabled`: Whether to throttle posting. Defaults to false.
|
|
|
|
* `count`: Each user can make this many posts in 'timespan' seconds. So, if count
|
|
is 100 and timespan is 3600, then there can be only 100 posts
|
|
from a user every hour.
|
|
|
|
* `timespan`: see 'count'.
|
|
|
|
|
|
profile
|
|
-------------------------------------------------------------------------------
|
|
|
|
Profile management.
|
|
|
|
* `biolimit`: max character length of bio; 0 means no limit; null means to use
|
|
the site text limit default.
|
|
|
|
* `backup`: whether users can backup their own profiles. Defaults to true.
|
|
|
|
* `restore`: whether users can restore their profiles from backup files. Defaults
|
|
to true.
|
|
|
|
* `delete`: whether users can delete their own accounts. Defaults to false.
|
|
|
|
* `move`: whether users can move their accounts to another server. Defaults
|
|
to true.
|
|
|
|
|
|
newuser
|
|
-------------------------------------------------------------------------------
|
|
|
|
Options with new users.
|
|
|
|
* `default`: nickname of a user account to automatically subscribe new
|
|
users to. Typically this would be system account for e.g.
|
|
service updates or announcements. Users are able to unsub
|
|
if they want. Default is null; no auto subscribe.
|
|
|
|
* `welcome`: nickname of a user account that sends welcome messages to new
|
|
users. Can be the same as 'default' account, although on
|
|
busy servers it may be a good idea to keep that one just for
|
|
'urgent' messages. Default is null; no message.
|
|
|
|
If either of these special user accounts are specified, the users should
|
|
be created before the configuration is updated.
|
|
|
|
|
|
attachments
|
|
-------------------------------------------------------------------------------
|
|
|
|
The software lets users upload files with their notices. You can configure
|
|
the types of accepted files by mime types and a trio of quota options:
|
|
per file, per user (total), per user per month.
|
|
|
|
We suggest the use of the pecl file_info extension to handle mime type
|
|
detection.
|
|
|
|
* `supported`: an array of mime types you accept to store and distribute,
|
|
like 'image/gif', 'video/mpeg', 'audio/mpeg', etc. Make sure you
|
|
setup your server to properly recognize the types you want to
|
|
support. It's important to use the result of calling `image_type_to_extension`
|
|
for the appropriate image type, in the case of images. This is so all parts of
|
|
the code see the same extension for each image type (jpg vs jpeg).
|
|
For example, to enable BMP uploads, add this to the config.php file:
|
|
$config['attachments']['supported'][image_type_to_mime_type(IMAGETYPE_GIF)]
|
|
= image_type_to_extension(IMAGETYPE_GIF);
|
|
See https://www.php.net/manual/en/function.image-type-to-mime-type.php for a
|
|
list of such constants. If a filetype is not listed there, it's possible to add
|
|
the mimetype and the extension by hand, but they need to match those returned by
|
|
the file command.
|
|
|
|
* `uploads`: false to disable uploading files with notices (true by default).
|
|
|
|
For quotas, be sure you've set the upload_max_filesize and post_max_size
|
|
in php.ini to be large enough to handle your upload. In httpd.conf
|
|
(if you're using apache), check that the LimitRequestBody directive isn't
|
|
set too low (it's optional, so it may not be there at all).
|
|
|
|
* `extblacklist`: associative array to either deny certain extensions or
|
|
change them to a different one. For example:
|
|
$config['attachments']['extblacklist']['php'] = 'phps'; // this turns .php into .phps
|
|
$config['attachments']['extblacklist']['exe'] = false; // this would deny any uploads
|
|
// of files with the "exe" extension
|
|
|
|
* `process_links`: follow redirects and save all available file information
|
|
(mimetype, date, size, oembed, etc.). Defaults to true.
|
|
|
|
* `file_quota`: maximum size for a single file upload in bytes. A user can send
|
|
any amount of notices with attachments as long as each attachment
|
|
is smaller than file_quota.
|
|
|
|
* `user_quota`: total size in bytes a user can store on this server. Each user
|
|
can store any number of files as long as their total size does
|
|
not exceed the user_quota.
|
|
|
|
* `monthly_quota`: total size permitted in the current month. This is the total
|
|
size in bytes that a user can upload each month.
|
|
|
|
* `dir`: directory accessible to the Web process where uploads should go.
|
|
Defaults to the 'file' subdirectory of the install directory, which
|
|
should be writeable by the Web user.
|
|
|
|
* `server`: server name to use when creating URLs for uploaded files.
|
|
Defaults to null, meaning to use the default Web server. Using
|
|
a virtual server here can speed up Web performance.
|
|
|
|
* `path`: URL path, relative to the server, to find files. Defaults to
|
|
main path + '/file/'.
|
|
|
|
* `ssl`: whether to use HTTPS for file URLs. Defaults to null, meaning to
|
|
guess based on other SSL settings.
|
|
|
|
* `sslserver`: if specified, this server will be used when creating HTTPS
|
|
URLs. Otherwise, the site SSL server will be used, with /file/ path.
|
|
|
|
* `sslpath`: if this and the sslserver are specified, this path will be used
|
|
when creating HTTPS URLs. Otherwise, the attachments|path value
|
|
will be used.
|
|
|
|
* `show_thumbs`: show thumbnails in notice lists for uploaded images, and photos
|
|
and videos linked remotely that provide oEmbed info. Defaults to true.
|
|
|
|
* `show_html`: show (filtered) text/html attachments (and oEmbed HTML etc.).
|
|
Doesn't affect AJAX calls. Defaults to false.
|
|
|
|
* `filename_base`: for new files, choose one: 'upload', 'hash'. Defaults to hash.
|
|
|
|
|
|
group
|
|
-------------------------------------------------------------------------------
|
|
|
|
Options for group functionality.
|
|
|
|
* `maxaliases`: maximum number of aliases a group can have. Default 3. Set
|
|
to 0 or less to prevent aliases in a group.
|
|
|
|
* `desclimit`: maximum number of characters to allow in group descriptions.
|
|
null (default) means to use the site-wide text limits. 0
|
|
means no limit.
|
|
|
|
* `addtag`: Whether to add a tag for the group nickname for every group post
|
|
(pre-1.0.x behaviour). Defaults to false.
|
|
|
|
|
|
search
|
|
-------------------------------------------------------------------------------
|
|
|
|
Some stuff for search.
|
|
|
|
* `type`: type of search. Ignored if PostgreSQL or Sphinx are enabled. Can either
|
|
be 'fulltext' or 'like' (default). The former is faster and more efficient
|
|
but requires the lame old MyISAM engine for MySQL. The latter
|
|
will work with InnoDB but could be miserably slow on large
|
|
systems. We'll probably add another type sometime in the future,
|
|
with our own indexing system (maybe like MediaWiki's).
|
|
|
|
|
|
sessions
|
|
-------------------------------------------------------------------------------
|
|
|
|
Session handling.
|
|
|
|
* `handle`: boolean. Whether we should register our own PHP session-handling
|
|
code (using the database and cache layers if enabled). Defaults to false.
|
|
Setting this to true makes some sense on large or multi-server
|
|
sites, but it probably won't hurt for smaller ones, either.
|
|
|
|
* `debug`: whether to output debugging info for session storage. Can help
|
|
with weird session bugs, sometimes. Default false.
|
|
|
|
|
|
ping
|
|
-------------------------------------------------------------------------------
|
|
|
|
Using the "XML-RPC Ping" method initiated by weblogs.com, the site can
|
|
notify third-party servers of updates.
|
|
|
|
* `notify`: an array of URLs for ping endpoints. Default is the empty
|
|
array (no notification).
|
|
|
|
|
|
notice
|
|
-------------------------------------------------------------------------------
|
|
|
|
Configuration options specific to notices.
|
|
|
|
* `contentlimit`: max length of the plain-text content of a notice.
|
|
Default is null, meaning to use the site-wide text limit.
|
|
0 means no limit.
|
|
|
|
* `defaultscope`: default scope for notices. If null, the default
|
|
scope depends on site/private. It's 1 if the site is private,
|
|
0 otherwise. Set this value to override.
|
|
|
|
|
|
message
|
|
-------------------------------------------------------------------------------
|
|
|
|
Configuration options specific to messages.
|
|
|
|
* `contentlimit`: max length of the plain-text content of a message.
|
|
Default is null, meaning to use the site-wide text limit.
|
|
0 means no limit.
|
|
|
|
|
|
logincommand
|
|
-------------------------------------------------------------------------------
|
|
|
|
Configuration options for the login command.
|
|
|
|
* `disabled`: whether to enable this command. If enabled, users who send
|
|
the text 'login' to the site through any channel will
|
|
receive a link to login to the site automatically in return.
|
|
Possibly useful for users who primarily use an XMPP or SMS
|
|
interface and can't be bothered to remember their site
|
|
password. Note that the security implications of this are
|
|
pretty serious and have not been thoroughly tested. You
|
|
should enable it only after you've convinced yourself that
|
|
it is safe. Default is 'false'.
|
|
|
|
|
|
singleuser
|
|
-------------------------------------------------------------------------------
|
|
|
|
If an installation has only one user, this can simplify a lot of the
|
|
interface. It also makes the user's profile the root URL.
|
|
|
|
* `enabled` (boolean, default true): Whether to run in "single user mode".
|
|
|
|
* `nickname` (string, default null): nickname of the single user. If no nickname is
|
|
specified, the site owner account will be used (if present).
|
|
|
|
|
|
robotstxt
|
|
-------------------------------------------------------------------------------
|
|
|
|
We put out a default robots.txt file to guide the processing of
|
|
Web crawlers. See http://www.robotstxt.org/ for more information
|
|
on the format of this file.
|
|
|
|
* `crawldelay`: if non-empty, this value is provided as the Crawl-Delay:
|
|
for the robots.txt file. see <https://en.wikipedia.org/wiki/Robots_exclusion_standard#Crawl-delay_directive>
|
|
for more information. Default is zero, no explicit delay.
|
|
|
|
* `disallow`: Array of (virtual) directories to disallow. Default is 'main',
|
|
'search', 'message', 'settings', 'admin'. Ignored when site
|
|
is private, in which case the entire site ('/') is disallowed.
|
|
|
|
|
|
api
|
|
---
|
|
|
|
Options for the Twitter-like API.
|
|
|
|
* `realm`: HTTP Basic Auth realm (see http://tools.ietf.org/html/rfc2617
|
|
for details). Some third-party tools like ping.fm want this to be
|
|
'Identi.ca API', so set it to that if you want to. default = null,
|
|
meaning 'something based on the site name'.
|
|
|
|
|
|
nofollow
|
|
--------
|
|
|
|
We optionally put 'rel="nofollow"' on some links in some pages. The
|
|
following configuration settings let you fine-tune how or when things
|
|
are nofollowed. See http://en.wikipedia.org/wiki/Nofollow for more
|
|
information on what 'nofollow' means.
|
|
|
|
* `subscribers`: whether to nofollow links to subscribers on the profile
|
|
and personal pages. Default is true.
|
|
|
|
* `members`: links to members on the group page. Default true.
|
|
|
|
* `peopletag`: links to people listed in the peopletag page. Default true.
|
|
|
|
* `external`: external links in notices. One of three values: 'sometimes',
|
|
'always', 'never'. If 'sometimes', then external links are not
|
|
nofollowed on profile, notice, and favorites page. Default is
|
|
'sometimes'.
|
|
|
|
url
|
|
---
|
|
|
|
These are some options for fine-tuning how and when the server will
|
|
shorten URLs.
|
|
|
|
* `shortener`: URL shortening service to use by default. Users can override
|
|
individually. 'internal' by default.
|
|
|
|
* `maxurllength`: If an URL is strictly longer than this limit, it will be
|
|
shortened. Note that the URL shortener service may return an
|
|
URL longer than this limit. Defaults to 100. Users can
|
|
override. If set to 0, all URLs will be shortened.
|
|
|
|
* `maxnoticelength`: If a notice is strictly longer than this limit, all
|
|
URLs in the notice will be shortened. Users can override.
|
|
-1 means the text limit for notices.
|
|
|
|
|
|
router
|
|
------
|
|
|
|
We use a router class for mapping URLs to code. This section controls
|
|
how that router works.
|
|
|
|
* `cache`: whether to cache the router in cache layers. Defaults to true,
|
|
but may be set to false for developers (who might be actively
|
|
adding pages, so won't want the router cached) or others who see
|
|
strange behavior. You're unlikely to need this unless developing..
|
|
|
|
|
|
http
|
|
----
|
|
|
|
Settings for the HTTP client.
|
|
|
|

|
|
SSL peers. Default unset.
|
|
|
|

|
|
have the PHP curl extension installed for this to work.
|
|

|
* `proxy_host`: Host to use for proxying HTTP requests. If unset, doesn't
|
|
do any HTTP proxy stuff. Default unset.
|
|
|
|

|
|
|
|
plugins
|
|
-------
|

|
|
a default plugin, unset its value in this array.
|
|
|
|
* `locale_path`: path for finding plugin locale files. In the plugin's directory
|
|
by default.
|
|
|
|
* `server`: Server to find static files for a plugin when the page is plain old HTTP.
|
|
Defaults to site/server (same as pages). Use this to move plugin CSS and
|
|
JS files to a CDN.
|
|
|
|
* `sslserver`: Server to find static files for a plugin when the page is HTTPS. Defaults
|
|
to site/server (same as pages). Use this to move plugin CSS and JS files
|
|
to a CDN.
|
|
|
|
* `path`: Path to the plugin files. defaults to site/path + '/plugins/'. Expects that
|
|
each plugin will have a subdirectory at plugins/NameOfPlugin. Change this
|
|
if you're using a CDN.
|
|
|
|
* `sslpath`: Path to use on the SSL server. Same as plugins/path.
|
|
|
|
|
|
performance
|
|
-----------
|
|
|
|
* `high`: if you need high performance, or if you're seeing bad
|
|
performance, set this to true. It will turn off some high-intensity code from
|
|
the site.
|
|
|
|
|
|
oldschool
|
|
---------
|
|
|
|
* `enabled`: enable certain old-style user settings options, like stream-only mode,
|
