Hi Bernie,

Yes, it is possible. This topic will be a good excuse to write a clean "quick start" for multisite on Piwigo!

Let's say you have Piwigo files on /var/www/piwigo

In your Apache configuration file, you need something like :

Alias /gallery /var/www/piwigo
Alias /gallery2 /var/www/piwigo

* create directories /var/www/piwigo/local-gallery and /var/www/piwigo/local-gallery2, with write access for www-data (chmod 0777 if you don't understand what www-data is)

* create file /var/www/piwigo/local/config/multisite.inc.php with the following content:

<?php
if (preg_match('#^/gallery#', $_SERVER['SCRIPT_NAME']))
{
  $conf['local_dir_site'] = 'local-gallery/';
}
elseif (preg_match('#^/gallery2#', $_SERVER['SCRIPT_NAME']))
{
  $conf['local_dir_site'] = 'local-gallery2/';
}

$conf['upload_dir'] = $conf['local_dir_site'].'upload';
?>

Then open http://mywebsite.com/gallery/ in your web browser, follow installation procedure and repeat the procedure for gallery2. The 2 Piwigo galleries can use the same database, but change the prefix for tables.

Unfortunately, the steps you gave are not working. These are the steps I went through and the error that occurs.

1. I created the local-gallery and local-gallery2 folders with write access.
2. I created multisite.inc.php and uploaded it to piwigo/local/config.
3. I went to http://mywebsite.com/gallery/ where I was presented with the  installation page. I entered the information and ran the installation. Then I received a page with the following error:


Creation of config file local/config/database.inc.php failed.

You can download the config file and upload it to local/config directory of your installation.

An alternate solution is to copy the text in the box above and paste it into the file "local/config/database.inc.php" (Warning : database.inc.php must only contain what is in the textarea, no line return or space character)

Why is the installation trying to save the file to local/config/database.inc.php? Shouldn't it be saving the file to local-gallery/config/database.inc.php?

After doing this, if I browse to http://mywebsite.com/gallery/, I am presented with the installation page again.

Am I missing something?

The error message is misleading. Actually Piwigo tries to write local-gallery/config/database.inc.php but the error message says something else. Trust me, install.php takes the $conf['local_dir_site'] configuration parameter into account (this is how Piwigo.com works and there are new installs every day ;-)

The problem was that Piwigo had no write access to local-gallery/config/database.inc.php

The code has changed on Piwigo 2.4 (no more multisite.inc.php file), see the wiki : Multiple Site
