Prerequisites
=============

PHP modules
-----------

The following software packages are *required* for this software to
run correctly.

- PHP 5.5+      For newer versions, some functions that are used may be
                disabled by default, such as the pcntl_* family. See the
                section on 'Queues and daemons' for more information.
- MariaDB 5+    GNU Social uses, by default, a MariaDB server for data
                storage. Versions 5.x and 10.x have both reportedly
                worked well. It is also possible to run MySQL 5.5+.
- 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)
- 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.

The above package names are for Debian based systems. In the case of
Arch Linux, PHP is compiled with support for most extensions but they
require manual enabling in the relevant php.ini file (mostly php5-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
- 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.

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. You should also take this moment to make your 'avatar' and 'file' sub-
   directories writeable by the Web server. The _insecure_ way to do
   this is:

       chmod a+w /var/www/gnusocial/avatar
       chmod a+w /var/www/gnusocial/file

   You can also make the avatar, and file directories just writable by
   the Web server group, as noted above.

5. 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.)

6. 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.

7. 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.

8. 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.

Plugins
=======

GNU social supports a simple but
powerful plugin architecture. Important events in the code are named,
like 'StartNoticeSave', and other software can register interest
in those events. When the events happen, the other software is called
and has a choice of accepting or rejecting the events.

In the simplest case, you can add a function to config.php and use the
Event::addHandler() function to hook an event:

    function AddGoogleLink($action)
    {
        $action->menuItem('http://www.google.com/', _('Google'), _('Search engine'));
        return true;
    }

    Event::addHandler('EndPrimaryNav', 'AddGoogleLink');

This adds a menu item to the end of the main navigation menu. You can
see the list of existing events, and parameters that handlers must
implement, in EVENTS.txt.

The Plugin class in lib/plugin.php makes it easier to write more
complex plugins. Sub-classes can just create methods named
'onEventName', where 'EventName' is the name of the event (case
matters!). These methods will be automatically registered as event
handlers by the Plugin constructor (which you must call from your own
class's constructor).

Several example plugins are included in the plugins/ directory. You
can enable a plugin with the following line in config.php:

    addPlugin('Example', array('param1' => 'value1',
                               'param2' => 'value2'));

This will look for and load files named 'ExamplePlugin.php' or
'Example/ExamplePlugin.php' either in the plugins/ directory (for
plugins that ship with GNU social) or in the local/ directory (for
plugins you write yourself or that you get from somewhere else) or
local/plugins/.

Plugins are documented in their own directories.

## About

GNU social is a free social networking
platform. It helps people in a community, company
or group to exchange short status updates, do
polls, announce events, or other social activities
(and you can add more!). Users can choose which
people to "follow" and receive only their friends'
or colleagues' status messages. It provides a
similar service to sites like Twitter, Google+ or
Facebook, but is much more awesome.

With a little work, status messages can be sent to
mobile phones, instant messenger programs (using
XMPP), and specially-designed desktop clients that
support the Twitter API.

GNU social supports an open standard called
OStatus <https://www.w3.org/community/ostatus/> that lets users in
different networks follow each other. It enables a
distributed social network spread all across the
Web.

GNU social was originally developed as "StatusNet" by
StatusNet, Inc. with Evan Prodromou as lead developer.

It is shared with you in hope that you too make an
service available to your users. To learn more,
please see the Open Software Service Definition
1.1: <http://www.opendefinition.org/ossd>

## New this version

This is the development branch for the 1.2.x version of GNU social.
All daring 1.1.x admins should upgrade to this version.

So far it includes the following changes:

- Backing up a user's account is more and more complete.
- Emojis 😸 (utf8mb4 support)

The last release, 1.1.3, gave us these improvements:

- XSS security fix (thanks Simon Waters, <https://www.surevine.com/>)
- Many improvements to ease adoption of the Qvitter front-end <https://github.com/hannesmannerheim/qvitter>
- Protocol adaptions for improved performance and stability

Upgrades from _StatusNet_ 1.1.1 will also experience these improvements:

- Fixes for SQL injection errors in profile lists.
- Improved ActivityStreams JSON representation of activities and objects.
- Upgrade to the Twitter 1.1 API.
- More robust handling of errors in distribution.
- Fix error in OStatus subscription for remote groups.
- Fix error in XMPP distribution.
- Tracking of conversation URI metadata (more coherent convos)

### Troubleshooting

The primary output for GNU social is syslog,
unless you configured a separate logfile. This is
probably the first place to look if you're getting
weird behaviour from GNU social.

If you're tracking the unstable version of
GNU social in the git repository (see below), and you
get a compilation error ("unexpected T_STRING") in
the browser, check to see that you don't have any
conflicts in your code.

### Unstable version

If you're adventurous or impatient, you may want
to install the development version of GNU social.
To get it, use the git version control tool
<http://git-scm.com/> like so:

    git clone git@git.gnu.io:gnu/gnu-social.git

In the current phase of development it is probably
recommended to use git as a means to stay up to date
with the source code. You can choose between these
branches:
- 1.2.x     "stable", few updates, well tested code
- master    "testing", more updates, usually working well
- nightly   "unstable", most updates, not always working

To keep it up-to-date, use 'git pull'. Watch for conflicts!

Things to be done
=================

* Create a theme for GNU social

* Create a set of plugins to give StatusNet a more social-network UI

* Work on improvements for annoying things in StatusNet (ie. no
  redirect to login page when you need to be logged in, etc)

* Work on adding further Activities, such as sharing photos/video,
  events, UI for managing relationships.

Upgrading
=========

GNU social 1.1.x to GNU social 1.2.x
------------------------------------

If you are tracking the GNU social git repository, we currently recommend
using the "master" branch (or nightly if you want to use latest features)
and follow this procedure:

0. Backup your data. The StatusNet upgrade discussions below have some
    guidelines to back up the database and files (mysqldump and rsync).

1. Stop your queue daemons (you can run this command even if you do not
    use the queue daemons):
    $ bash scripts/stopdaemons.sh

2. Run the command to fetch the latest sourcecode:
    $ git pull

    If you are not using git we recommend following the instructions below
    for upgrading "StatusNet 1.1.x to GNU social 1.2.x" as they are similar.

3. Run the upgrade script:
    $ php scripts/upgrade.php

   The upgrade script will likely take a long time because it will
    upgrade the tables to another character encoding and make other
    automated upgrades. Make sure it ends without errors. If you get
    errors, create a new task on https://git.gnu.io/gnu/gnu-social/issues

4. Start your queue daemons again (you can run this command even if you
    do not use the queue daemons):
    $ bash scripts/startdaemons.sh

5. Report any issues at https://git.gnu.io/gnu/gnu-social/issues

If you are using ssh keys to log in to your server, you can make this
procedure pretty painless (assuming you have automated backups already).
Make sure you "cd" into the correct directory (in this case "htdocs")
and use the correct login@hostname combo:
    $ ssh social@domain.example 'cd htdocs
            && bash scripts/stopdaemons.sh
            && git pull
            && time php scripts/upgrade.php
            && bash scripts/startdaemons.sh'

StatusNet 1.1.x to GNU social 1.2.x
-----------------------------------

We cannot support migrating from any other version of StatusNet than
1.1.1. If you are running a StatusNet version lower than this, please
follow the upgrade procedures for each respective StatusNet version.

You are now running StatusNet 1.1.1 and want to migrate to GNU social
1.2.x. Beware there may be changes in minimum required version of PHP
and the modules required, so review the INSTALL file (php5-intl is a
newly added dependency for example).

* Before you begin: Make backups. Always make backups. Of your entire
directory structure and the database too. All tables. All data. Alles.

0. Make a backup of everything. To backup the database, you can use a
variant of this command (you will be prompted for the database password):
    $ mysqldump -u dbuser -p dbname > social-backup.sql

1. Stop your queue daemons 'bash scripts/stopdaemons.sh' should do it.
    Not everyone runs queue daemons, but the above command won't hurt.

2. Unpack your GNU social code to a fresh directory. You can do this
    by cloning our git repository:
    $ git clone https://git.gnu.io/gnu/gnu-social.git gnusocial

3. Synchronize your local files to the GNU social directory. These
    will be the local files such as avatars, config and files:

        avatar/*
        file/*
        local/*
        .htaccess
        config.php

    This command will point you in the right direction on how to do it:
    $ rsync -avP statusnet/{.htaccess,avatar,file,local,config.php} gnusocial/

4. Replace your old StatusNet directory with the new GNU social
    directory in your webserver root.

5. Run the upgrade script: 'php scripts/upgrade.php'
   The upgrade script will likely take a long time because it will
    upgrade the tables to another character encoding and make other
    automated upgrades. Make sure it ends without errors. If you get
    errors, create a new task on https://git.gnu.io/gnu/gnu-social/issues

6. Start your queue daemons: 'bash scripts/startdaemons.sh'

7. Report any issues at https://git.gnu.io/gnu/gnu-social/issues
