-PHP modules
------------
-
-The following software packages are *required* for this software to
-run correctly.
-
-- PHP 5.6+ PHP7.x is also supported.
-- MariaDB 5+ MariaDB 10.x is also supported.
-- Web server Apache, lighttpd and nginx will all work, see sample
- configuration files in the web root. Please use PHP-FPM
- and configure mod_rewrite (or equivalent) for an optimal
- experience.
-
-Your PHP installation must include the following PHP extensions for a
-functional setup of GNU Social:
-
-- openssl (compiled in for Debian, enabled manually in Arch Linux)
-- php5-curl Fetching files by HTTP.
-- php5-gd Image manipulation (scaling).
-- php5-gmp For Salmon signatures (part of OStatus).
-- php5-intl Internationalization support (transliteration et al).
-- php5-json For WebFinger lookups and more.
-- php5-mysqlnd The native driver for PHP5 MariaDB connections. If you
- use MySQL, 'php5-mysql' or 'php5-mysqli' may be enough.
-
-Or, for PHP7, some or all of these will be necessary. PHP7 works and on
-the development servers we are successful running PHP7.2. This is a good
-list of PHP modules you will want installed with PHP7:
- php7.0-bcmath
- php7.0-curl
- php7.0-exif
- php7.0-gd
- php7.0-intl
- php7.0-mbstring
- php7.0-mysql
- php7.0-opcache
- php7.0-readline
- php7.0-xmlwriter
-
-NOTE: In Arch Linux, at least PHP5 requires manual enabling in the
-relevant php.ini for some modules, most notably 'gmp'.
-
-Better performance
-------------------
-
-For some functionality, you will also need the following extensions:
-
-- opcache Improves performance a _lot_. Included in PHP, must be
- enabled manually in php.ini for most distributions. Find
- and set at least: opcache.enable=1
-- gettext For multiple languages. Default on many PHP installs;
- will be emulated if not present.
-- exif For thumbnails to be properly oriented.
-
-Installation
-============
-
-Getting it up and running
--------------------------
-
-Installing the basic GNU Social web component is relatively easy,
-especially if you've previously installed PHP/MariaDB packages.
-
-1. Unpack the tarball you downloaded on your Web server. Usually a
- command like this will work:
-
- tar zxf gnusocial-*.tar.gz
-
- ...which will make a gnusocial-x.y.z subdirectory in your current
- directory. (If you don't have shell access on your Web server, you
- may have to unpack the tarball on your local computer and FTP the
- files to the server.)
-
-2. Move the tarball to a directory of your choosing in your Web root
- directory. Usually something like this will work:
-
- mv gnusocial-x.y.z /var/www/gnusocial
-
- This will often make your GNU Social instance available in the gnusocial
- path of your server, like "http://example.net/gnusocial". "social" or
- "blog" might also be good path names. If you know how to configure
- virtual hosts on your web server, you can try setting up
- "http://social.example.net/" or the like.
-
- If you have "rewrite" support on your webserver, and you should,
- then please enable this in order to make full use of your site. This
- will enable "Fancy URL" support, which you can read more about if you
- scroll down a bit in this document.
-
-3. Make your target directory writeable by the Web server, please note
- however that 'a+w' will give _all_ users write access and securing the
- webserver is not within the scope of this document.
-
- chmod a+w /var/www/gnusocial/
-
- On some systems, this will work as a more secure alternative:
-
- chgrp www-data /var/www/gnusocial/
- chmod g+w /var/www/gnusocial/
-
- If your Web server runs as another user besides "www-data", try
- that user's default group instead. As a last resort, you can create
- a new group like "gnusocial" and add the Web server's user to the group.
-
-4. Create a database to hold your site data. Something like this
- should work (you will be prompted for your database password):
-
- mysqladmin -u "root" -p create social
-
- Note that GNU Social should have its own database; you should not share
- the database with another program. You can name it whatever you want,
- though.
-
- (If you don't have shell access to your server, you may need to use
- a tool like phpMyAdmin to create a database. Check your hosting
- service's documentation for how to create a new MariaDB database.)
-
-5. Create a new database account that GNU Social will use to access the
- database. If you have shell access, this will probably work from the
- MariaDB shell:
-
- GRANT ALL on social.*
- TO 'social'@'localhost'
- IDENTIFIED BY 'agoodpassword';
-
- You should change the user identifier 'social' and 'agoodpassword'
- to your preferred new database username and password. You may want to
- test logging in to MariaDB as this new user.
-
-6. In a browser, navigate to the GNU Social install script; something like:
-
- https://social.example.net/install.php
-
- Enter the database connection information and your site name. The
- install program will configure your site and install the initial,
- almost-empty database.
-
-7. You should now be able to navigate to your social site's main directory
- and see the "Public Timeline", which will probably be empty. You can
- now register new user, post some notices, edit your profile, etc.
-
-Fancy URLs
-----------
-
-By default, GNU Social will use URLs that include the main PHP program's
-name in them. For example, a user's home profile might be found at either
-of these URLS depending on the webserver's configuration and capabilities:
-
- https://social.example.net/index.php/fred
- https://social.example.net/index.php?p=fred
-
-It's possible to configure the software to use fancy URLs so it looks like
-this instead:
-
- https://social.example.net/fred
-
-These "fancy URLs" are more readable and memorable for users. To use
-fancy URLs, you must either have Apache 2.x with .htaccess enabled and
-mod_rewrite enabled, -OR- know how to configure "url redirection" in
-your server (like lighttpd or nginx).
-
-1. See the instructions for each respective webserver software:
- * For Apache, inspect the "htaccess.sample" file and save it as
- ".htaccess" after making any necessary modifications. Our sample
- file is well commented.
- * For lighttpd, inspect the lighttpd.conf.example file and apply the
- appropriate changes in your virtualhost configuration for lighttpd.
- * For nginx, inspect the nginx.conf.sample file and apply the appropriate
- changes.
- * For other webservers, we gladly accept contributions of
- server configuration examples.
-
-2. Assuming your webserver is properly configured and have its settings
- applied (remember to reload/restart it), you can add this to your
- GNU social's config.php file:
- $config['site']['fancy'] = true;
-
-You should now be able to navigate to a "fancy" URL on your server,
-like:
-
- https://social.example.net/main/register
-
-Themes
-------
-
-As of right now, your ability change the theme is limited to CSS
-stylesheets and some image files; you can't change the HTML output,
-like adding or removing menu items, without the help of a plugin.
-
-You can choose a theme using the $config['site']['theme'] element in
-the config.php file. See below for details.
-
-You can add your own theme by making a sub-directory of the 'theme'
-subdirectory with the name of your theme. Each theme can have the
-following files:
-
-display.css: a CSS2 file for "default" styling for all browsers.
-logo.png: a logo image for the site.
-default-avatar-profile.png: a 96x96 pixel image to use as the avatar for
- users who don't upload their own.
-default-avatar-stream.png: Ditto, but 48x48. For streams of notices.
-default-avatar-mini.png: Ditto ditto, but 24x24. For subscriptions
- listing on profile pages.
-
-You may want to start by copying the files from the default theme to
-your own directory.
-
-Private
--------
-
-A GNU social node can be configured as "private", which means it will not
-federate with other nodes in the network. It is not a recommended method
-of using GNU social and we cannot at the current state of development
-guarantee that there are no leaks (what a public network sees as features,
-private sites will likely see as bugs).
-
-Private nodes are however an easy way to easily setup collaboration and
-image sharing within a workgroup or a smaller community where federation
-is not a desired feature. Also, it is possible to change this setting and
-instantly gain full federation features.
-
-Access to file attachments can also be restricted to logged-in users only:
-
-1. Add a directory outside the web root where your file uploads will be
- stored. Use this command as an initial guideline to create it:
-
- mkdir /var/www/gnusocial-files
-
-2. Make the file uploads directory writeable by the web server. An
- insecure way to do this is (to do it properly, read up on UNIX file
- permissions and configure your webserver accordingly):
-
- chmod a+x /var/www/gnusocial-files
-
-3. Tell GNU social to use this directory for file uploads. Add a line
- like this to your config.php:
-
- $config['attachments']['dir'] = '/var/www/gnusocial-files';
-
-Extra features
-==============
-
-Sphinx
-------
-
-To use a Sphinx server to search users and notices, you'll need to
-enable the SphinxSearch plugin. Add to your config.php:
-
- addPlugin('SphinxSearch');
- $config['sphinx']['server'] = 'searchhost.local';
-
-You also need to install, compile and enable the sphinx pecl extension for
-php on the client side, which itself depends on the sphinx development files.
-
-See plugins/SphinxSearch/README for more details and server setup.
-
-SMS
----
-
-StatusNet supports a cheap-and-dirty system for sending update messages
-to mobile phones and for receiving updates from the mobile. Instead of
-sending through the SMS network itself, which is costly and requires
-buy-in from the wireless carriers, it simply piggybacks on the email
-gateways that many carriers provide to their customers. So, SMS
-configuration is essentially email configuration.
-
-Each user sends to a made-up email address, which they keep a secret.
-Incoming email that is "From" the user's SMS email address, and "To"
-the users' secret email address on the site's domain, will be
-converted to a notice and stored in the DB.
-
-For this to work, there *must* be a domain or sub-domain for which all
-(or most) incoming email can pass through the incoming mail filter.
-
-1. Run the SQL script carrier.sql in your StatusNet database. This will
- usually work:
-
- mysql -u "statusnetuser" --password="statusnetpassword" statusnet < db/carrier.sql
-
- This will populate your database with a list of wireless carriers
- that support email SMS gateways.
-
-2. Make sure the maildaemon.php file is executable:
-
- chmod +x scripts/maildaemon.php
-
- Note that "daemon" is kind of a misnomer here; the script is more
- of a filter than a daemon.
-
-2. Edit /etc/aliases on your mail server and add the following line:
-
- *: /path/to/statusnet/scripts/maildaemon.php
-
-3. Run whatever code you need to to update your aliases database. For
- many mail servers (Postfix, Exim, Sendmail), this should work:
-
- newaliases
-
- You may need to restart your mail server for the new database to
- take effect.
-
-4. Set the following in your config.php file:
-
- $config['mail']['domain'] = 'yourdomain.example.net';
-
-Translations
-------------
-
-For info on helping with translations, see the platform currently in use
-for translations: https://www.transifex.com/projects/p/gnu-social/
-
-Translations use the gettext system <http://www.gnu.org/software/gettext/>.
-If you for some reason do not wish to sign up to the Transifex service,
-you can review the files in the "locale/" sub-directory of GNU social.
-Each plugin also has its own translation files.
-
-To get your own site to use all the translated languages, and you are
-tracking the git repo, you will need to install at least 'gettext' on
-your system and then run:
- $ make translations
-
-Queues and daemons
-------------------
-
-Some activities that StatusNet needs to do, like broadcast OStatus, SMS,
-XMPP messages and TwitterBridge operations, can be 'queued' and done by
-off-line bots instead.
-
-Two mechanisms are available to achieve offline operations:
-
-* New embedded OpportunisticQM plugin, which is enabled by default
-* Legacy queuedaemon script, which can be enabled via config file.
-
-### OpportunisticQM plugin
-
-This plugin is enabled by default. It tries its best to do background
-jobs during regular HTTP requests, like API or HTML pages calls.
-
-Since queueing system is enabled by default, notices to be broadcasted
-will be stored, by default, into DB (table queue_item).
-
-Whenever it has time, OpportunisticQM will try to handle some of them.
-
-This is a good solution whether you:
-
-* have no access to command line (shared hosting)
-* do not want to deal with long-running PHP processes
-* run a low traffic GNU social instance
-
-In other case, you really should consider enabling the queuedaemon for
-performance reasons. Background daemons are necessary anyway if you wish
-to use the Instant Messaging features such as communicating via XMPP.
-
-### queuedaemon
-
-If you want to use legacy queuedaemon, you must be able to run
-long-running offline processes, either on your main Web server or on
-another server you control. (Your other server will still need all the
-above prerequisites, with the exception of Apache.) Installing on a
-separate server is probably a good idea for high-volume sites.
-
-1. You'll need the "CLI" (command-line interface) version of PHP
- installed on whatever server you use.
-
- Modern PHP versions in some operating systems have disabled functions
- related to forking, which is required for daemons to operate. To make
- this work, make sure that your php-cli config (/etc/php5/cli/php.ini)
- does NOT have these functions listed under 'disable_functions':
-
- * pcntl_fork, pcntl_wait, pcntl_wifexited, pcntl_wexitstatus,
- pcntl_wifsignaled, pcntl_wtermsig
-
- Other recommended settings for optimal performance are:
- * mysqli.allow_persistent = On
- * mysqli.reconnect = On
-
-2. If you're using a separate server for queues, install StatusNet
- somewhere on the server. You don't need to worry about the
- .htaccess file, but make sure that your config.php file is close
- to, or identical to, your Web server's version.
-
-3. In your config.php files (on the server where you run the queue
- daemon), set the following variable:
-
- $config['queue']['daemon'] = true;
-
- You may also want to look at the 'Queues and Daemons' section in
- this file for more background processing options.
-
-4. On the queues server, run the command scripts/startdaemons.sh.
-
-This will run the queue handlers:
-
-* queuedaemon.php - polls for queued items for inbox processing and
- pushing out to OStatus, SMS, XMPP, etc.
-* imdaemon.php - if an IM plugin is enabled (like XMPP)
-* other daemons, like TwitterBridge ones, that you may have enabled
-
-These daemons will automatically restart in most cases of failure
-including memory leaks (if a memory_limit is set), but may still die
-or behave oddly if they lose connections to the XMPP or queue servers.
-
-It may be a good idea to use a daemon-monitoring service, like 'monit',
-to check their status and keep them running.
-
-All the daemons write their process IDs (pids) to /var/run/ by
-default. This can be useful for starting, stopping, and monitoring the
-daemons. If you are running multiple sites on the same machine, it will
-be necessary to avoid collisions of these PID files by setting a site-
-specific directory in config.php:
-
- $config['daemon']['piddir'] = __DIR__ . '/../run/';
-
-It is also possible to use a STOMP server instead of our kind of hacky
-home-grown DB-based queue solution. This is strongly recommended for
-best response time, especially when using XMPP.
-
-After installation
-==================
-
-Backups
--------
-
-There is no built-in system for doing backups in GNU social. You can make
-backups of a working StatusNet system by backing up the database and
-the Web directory. To backup the database use mysqldump <https://mariadb.com/kb/en/mariadb/mysqldump/>
-and to backup the Web directory, try tar.
-
-Upgrading
----------
-
-Upgrading is strongly recommended to stay up to date with security fixes
-and new features. For instructions on how to upgrade GNU social code,
-please see the UPGRADE file.
-
-Additional configuration
-------------------------
-
-Please refer to DOCUMENTATION/SYSTEM_ADMINISTRATORS/CONFIGURE for information.

+PHP modules
+-----------
+
+The following software packages are *required* for this software to
+run correctly.
+
+- PHP 7+ PHP7.x is also supported.
+- MariaDB 5+ MariaDB 10.x is also supported.
+- Web server Apache, lighttpd and nginx will all work. CGI mode is
+ recommended and also some variant of 'suexec' (or a
+ proper setup php-fpm pool)
+ NOTE: mod_rewrite or its equivalent is extremely useful.
+
+Your PHP installation must include the following PHP extensions for a
+functional setup of GNU social:
+
+- openssl (compiled in for Debian, enabled manually in Arch Linux)
+- php-curl Fetching files by HTTP.
+- php-exif Exchangeable image information.
+- php-gd Image manipulation (scaling).
+- php-intl Internationalization support (transliteration et al).
+- php-json For WebFinger lookups and more.
+- php-mbstring String manipulation
+- php-mysql The native driver for MariaDB connections.
+- php-gmp For Salmon signatures (part of OStatus)
+- php-bcmath Arbitrary Precision Mathematics
+- php-opcache Improved PHP performance by precompilation
+- php-readline For interactive scripts
+- php-xml XML parser
+- php-ds Faster data structures
+
+NOTE: Some distros require manual enabling in the relevant php.ini for some modules.
+
+Better performance
+------------------
+
+For some functionality, you will also need the following extensions:
+
+- opcache Improves performance a _lot_. Included in PHP, must be
+ enabled manually in php.ini for most distributions. Find
+ and set at least: opcache.enable=1
+- mailparse Efficient parsing of email requires this extension.
+ Submission by email or SMS-over-email uses this.
+- sphinx A client for the sphinx server, an alternative to MySQL
+ or Postgresql fulltext search. You will also need a
+ Sphinx server to serve the search queries.
+- gettext For multiple languages. Default on many PHP installs;
+ will be emulated if not present.
+- exif For thumbnails to be properly oriented.
+- php-ds For faster data structures; will be emulated if not present.
+
+You may also experience better performance from your site if you configure
+a PHP cache/accelerator. Most distributions come with "opcache" support.
+Enable it in your php.ini where it is documented together with its settings.
+
+Installation
+============
+
+Getting it up and running
+-------------------------
+
+Installing the basic GNU Social web component is relatively easy,
+especially if you've previously installed PHP/MariaDB packages.
+
+1. Unpack the tarball you downloaded on your Web server. Usually a
+ command like this will work:
+
+ tar zxf gnusocial-*.tar.gz
+
+ ...which will make a gnusocial-x.y.z subdirectory in your current
+ directory. (If you don't have shell access on your Web server, you
+ may have to unpack the tarball on your local computer and FTP the
+ files to the server.)
+
+2. Move the tarball to a directory of your choosing in your Web root
+ directory. Usually something like this will work:
+
+ mv gnusocial-x.y.z /var/www/gnusocial
+
+ This will often make your GNU Social instance available in the gnusocial
+ path of your server, like "http://example.net/gnusocial". "social" or
+ "blog" might also be good path names. If you know how to configure
+ virtual hosts on your web server, you can try setting up
+ "http://social.example.net/" or the like.
+
+ If you have "rewrite" support on your webserver, and you should,
+ then please enable this in order to make full use of your site. This
+ will enable "Fancy URL" support, which you can read more about if you
+ scroll down a bit in this document.
+
+3. Make your target directory writeable by the Web server, please note
+ however that 'a+w' will give _all_ users write access and securing the
+ webserver is not within the scope of this document.
+
+ chmod a+w /var/www/gnusocial/
+
+ On some systems, this will work as a more secure alternative:
+
+ chgrp www-data /var/www/gnusocial/
+ chmod g+w /var/www/gnusocial/
+
+ If your Web server runs as another user besides "www-data", try
+ that user's default group instead. As a last resort, you can create
+ a new group like "gnusocial" and add the Web server's user to the group.
+
+4. Create a database to hold your site data. Something like this
+ should work (you will be prompted for your database password):
+
+ mysqladmin -u "root" -p create social
+
+ Note that GNU Social should have its own database; you should not share

+ though.
+
+ (If you don't have shell access to your server, you may need to use
+ a tool like phpMyAdmin to create a database. Check your hosting
+ service's documentation for how to create a new MariaDB database.)
+
+5. Create a new database account that GNU Social will use to access the
+ database. If you have shell access, this will probably work from the
+ MariaDB shell:
+
+ GRANT ALL on social.*
+ TO 'social'@'localhost'
+ IDENTIFIED BY 'agoodpassword';
+
+ You should change the user identifier 'social' and 'agoodpassword'
+ to your preferred new database username and password. You may want to
+ test logging in to MariaDB as this new user.
+
+6. In a browser, navigate to the GNU Social install script; something like:
+
+ https://social.example.net/install.php
+
+ Enter the database connection information and your site name. The
+ install program will configure your site and install the initial,
+ almost-empty database.
+
+7. You should now be able to navigate to your social site's main directory
+ and see the "Public Timeline", which will probably be empty. You can
+ now register new user, post some notices, edit your profile, etc.
+
+Fancy URLs
+----------
+
+By default, GNU Social will use URLs that include the main PHP program's
+name in them. For example, a user's home profile might be found at either
+of these URLS depending on the webserver's configuration and capabilities:
+
+ https://social.example.net/index.php/fred

+ $config['site']['fancy'] = true;
+
+You should now be able to navigate to a "fancy" URL on your server,

+StatusNet supports a cheap-and-dirty system for sending update messages
+to mobile phones and for receiving updates from the mobile. Instead of
+sending through the SMS network itself, which is costly and requires
+buy-in from the wireless carriers, it simply piggybacks on the email
+gateways that many carriers provide to their customers. So, SMS
+configuration is essentially email configuration.
+
+Each user sends to a made-up email address, which they keep a secret.
+Incoming email that is "From" the user's SMS email address, and "To"
+the users' secret email address on the site's domain, will be
+converted to a notice and stored in the DB.
+
+For this to work, there *must* be a domain or sub-domain for which all
+(or most) incoming email can pass through the incoming mail filter.
+
+1. Run the SQL script carrier.sql in your StatusNet database. This will
+ usually work:
+
+ mysql -u "statusnetuser" --password="statusnetpassword" statusnet < db/carrier.sql
+
+ This will populate your database with a list of wireless carriers
+ that support email SMS gateways.
+
+2. Make sure the maildaemon.php file is executable:
+
+ chmod +x scripts/maildaemon.php
+
+ Note that "daemon" is kind of a misnomer here; the script is more
+ of a filter than a daemon.
+
+2. Edit /etc/aliases on your mail server and add the following line:
+
+ *: /path/to/statusnet/scripts/maildaemon.php
+
+3. Run whatever code you need to to update your aliases database. For
+ many mail servers (Postfix, Exim, Sendmail), this should work:
+
+ newaliases
+
+ You may need to restart your mail server for the new database to
+ take effect.
+
+4. Set the following in your config.php file:
+
+ $config['mail']['domain'] = 'yourdomain.example.net';
+
+Translations
+------------
+
+For info on helping with translations, see the platform currently in use
+for translations: https://www.transifex.com/projects/p/gnu-social/
+
+Translations use the gettext system <http://www.gnu.org/software/gettext/>.
+If you for some reason do not wish to sign up to the Transifex service,
+you can review the files in the "locale/" sub-directory of GNU social.
+Each plugin also has its own translation files.
+
+To get your own site to use all the translated languages, and you are
+tracking the git repo, you will need to install at least 'gettext' on
+your system and then run:
+ $ make translations
+
+Queues and daemons
+------------------
+
+Some activities that StatusNet needs to do, like broadcast OStatus, SMS,
+XMPP messages and TwitterBridge operations, can be 'queued' and done by
+off-line bots instead.
+
+Two mechanisms are available to achieve offline operations:
+
+* New embedded OpportunisticQM plugin, which is enabled by default
+* Legacy queuedaemon script, which can be enabled via config file.
+
+### OpportunisticQM plugin
+
+This plugin is enabled by default. It tries its best to do background
+jobs during regular HTTP requests, like API or HTML pages calls.
+
+Since queueing system is enabled by default, notices to be broadcasted
+will be stored, by default, into DB (table queue_item).
+
+Whenever it has time, OpportunisticQM will try to handle some of them.
+
+This is a good solution whether you:
+
+* have no access to command line (shared hosting)
+* do not want to deal with long-running PHP processes
+* run a low traffic GNU social instance
+
+In other case, you really should consider enabling the queuedaemon for
+performance reasons. Background daemons are necessary anyway if you wish
+to use the Instant Messaging features such as communicating via XMPP.
+
+### queuedaemon
+
+If you want to use legacy queuedaemon, you must be able to run
+long-running offline processes, either on your main Web server or on
+another server you control. (Your other server will still need all the
+above prerequisites, with the exception of Apache.) Installing on a
+separate server is probably a good idea for high-volume sites.
+
+1. You'll need the "CLI" (command-line interface) version of PHP
+ installed on whatever server you use.
+
+ Modern PHP versions in some operating systems have disabled functions
+ related to forking, which is required for daemons to operate. To make
+ this work, make sure that your php-cli config (/etc/php5/cli/php.ini)
+ does NOT have these functions listed under 'disable_functions':
+
+ * pcntl_fork, pcntl_wait, pcntl_wifexited, pcntl_wexitstatus,
+ pcntl_wifsignaled, pcntl_wtermsig
+
+ Other recommended settings for optimal performance are:
+ * mysqli.allow_persistent = On
+ * mysqli.reconnect = On
+
+2. If you're using a separate server for queues, install StatusNet
+ somewhere on the server. You don't need to worry about the
+ .htaccess file, but make sure that your config.php file is close
+ to, or identical to, your Web server's version.
+
+3. In your config.php files (on the server where you run the queue
+ daemon), set the following variable:
+
+ $config['queue']['daemon'] = true;
+
+ You may also want to look at the 'Queues and Daemons' section in
+ this file for more background processing options.
+
+4. On the queues server, run the command scripts/startdaemons.sh.
+
+This will run the queue handlers:
+
+* queuedaemon.php - polls for queued items for inbox processing and
+ pushing out to OStatus, SMS, XMPP, etc.
+* imdaemon.php - if an IM plugin is enabled (like XMPP)
+* other daemons, like TwitterBridge ones, that you may have enabled
+
+These daemons will automatically restart in most cases of failure
+including memory leaks (if a memory_limit is set), but may still die
+or behave oddly if they lose connections to the XMPP or queue servers.
+
+It may be a good idea to use a daemon-monitoring service, like 'monit',
+to check their status and keep them running.
+
+All the daemons write their process IDs (pids) to /var/run/ by
+default. This can be useful for starting, stopping, and monitoring the
+daemons. If you are running multiple sites on the same machine, it will
+be necessary to avoid collisions of these PID files by setting a site-
+specific directory in config.php:
+
+ $config['daemon']['piddir'] = __DIR__ . '/../run/';
+
+It is also possible to use a STOMP server instead of our kind of hacky
+home-grown DB-based queue solution. This is strongly recommended for
+best response time, especially when using XMPP.
+
+After installation
+==================
+
+Backups
+-------
+
+There is no built-in system for doing backups in GNU social. You can make
+backups of a working StatusNet system by backing up the database and
+the Web directory. To backup the database use mysqldump <https://mariadb.com/kb/en/mariadb/mysqldump/>
+and to backup the Web directory, try tar.
+
+Upgrading
+---------
+
+Upgrading is strongly recommended to stay up to date with security fixes
+and new features. For instructions on how to upgrade GNU social code,
+please see the UPGRADE file.
