====== Multiple site (multisite) ======

The Multiple site feature, [[http://www.piwigo.org/releases/2.2.0#multisite|introduced in Piwigo 2.2]], is the  ability to have several galleries with a single Piwigo installed. This feature is used on [[http://piwigo.com|Piwigo.com]] where thousands of galleries run on one Piwigo installation.

===== Databases =====

Only the files are shared, each gallery has a specific database or a set of tables in the same database if you use a specific table prefix for each gallery.

===== Piwigo files =====

Download Piwigo and extract files on your web server, in /var/www/piwigo for example.

===== Web Server Configuration =====

In your Apache configuration file, you need something like:

<code>Alias /gallery1 /var/www/piwigo
Alias /gallery2 /var/www/piwigo</code>

Or if you like to do it on Server Name then just add a ServerAlias in your VirtualHost config:

<code>ServerName piwigo.yourdomain.com
ServerAlias gallery1.yourdomain.com
ServerAlias gallery2.yourdomain.com</code>
===== Site Directories =====

Create directories /var/www/piwigo/gallery1 and /var/www/piwigo/gallery2 and sub-drectories, with write access for www-data (chmod 0777 if you don't understand what www-data is)

<code bash>mkdir /var/www/piwigo/gallery1
cd /var/www/piwigo/gallery1
mkdir -p local/config _data upload
chown -R www-data:www-data .</code>

Let's do the same for gallery2:

<code bash>mkdir /var/www/piwigo/gallery2
cd /var/www/piwigo/gallery2
mkdir -p local/config _data upload
chown -R www-data:www-data .</code>

and so on for other sites.
===== Activate Multiple Site =====

In your local/config/config.inc.php, you need this kind of code:

<code php>
if (preg_match('#^/gallery1#', $_SERVER['SCRIPT_NAME']))
#if (preg_match('/^gallery1.yourdomain.com$/', $_SERVER['SERVER_NAME']))
{
  $site_dir = 'gallery1';
}
elseif (preg_match('#^/gallery2#', $_SERVER['SCRIPT_NAME']))
#elseif (preg_match('/^gallery2.yourdomain.com$/', $_SERVER['SERVER_NAME']))
{
  $site_dir = 'gallery2';
}

if (isset($site_dir))
{
  define('PWG_LOCAL_DIR', $site_dir.'/local/');
  $conf['upload_dir'] = './'.$site_dir.'/upload';
  $conf['data_location'] = $site_dir.'/_data/';
 
  # in case there is a specific configuration file for each "site"
  @include(PHPWG_ROOT_PATH.PWG_LOCAL_DIR. 'config/config.inc.php');
}
</code>

The trick is to find how Piwigo can understand if it's currently running gallery1 or gallery2. In this example, we have used the $_SERVER['SCRIPT_NAME'] variable. You can also use an environment variable set by your webserver or the servers name in the $_SERVER['SERVER_NAME'] variable (if you search for a specific sub-domain). If no Alias or Server Name matches it will just use the default, root gallery.
===== Installations =====

Now you have to go to each Piwigo gallery: http://yourdomain.com/gallery1 and http://yourdomain.com/gallery2 or http://gallery1.yourdomain.com/ and http://gallery2.yourdomain.com/ (if you match on Server Name) and follow the installation each time. keep in mind that the default, root gallery should be available somewhere at http://yourdoamin.com/piwigo or http://piwigo.yourdomain.com/.
