'''PLEASE NOTE:''' This tutorial is for Dolphin 6, please refer to [wiki:TutorialHowToReplicateDolphin Dolphin Replication] doc for the instructions for Dolphin 7.


----


Dolphin can be configured to work on a cluster. Cluster environment was provided by [http://www.boonex.com/hosting/hostforweb HostForWeb].

'''Firstly'''. Do not delete this file on your hosting server. It must be put on your server by your hosting provider.

    '''''status.html''''' - in root folder for load balancer.



'''Secondly'''. This is what must be done to configure Dolphin to work on 2 clusters.

You should install Dolphin on one of your servers ('''NOTE''': create databases on both of your servers using the same names) and run the installation script on one of your servers only. After you will have to copy the files from the installed version to the second server. The database will be replicated automatically on the second server from the first one.

Enter the root folder of Dolphin installation on both servers via SSH
and run the following script. It will link the folders of Dolphin to Network File System.


'''Note''': This is only an example of what must be done. The path to the
"'''/mnt/nas/'''" (Network File System) could be different on your server. So, the whole script must be re-written accordingly.
For this you can consult with your hosting provider or [http://www.boonex.com/contact/ contact us].

'''Third'''. Some changes should be applied in Orca.

In '''xml/config.php''' file, you should change your domain name to "http://localhost/:

{{{

$gConf['url']['xml'] = 'http://localhost/orca/xml/orca.php'; // xml integration file url

}}}

Dolphin Home page and Account Builder are affected. The URLs should be changed as follows:


{{{
homepage builder: {SiteUrl}orca/?action=rss_all -> http://localhost/orca/?action=rss_all
account builder : {SiteUrl}orca/?action=rss_user&user={NickName} ->  http://localhost/orca/?action=rss_user&user={NickName}
}}}


Dolphin's '''inc/header.inc.php''' file should be affected too:
 

{{{
header.inc.php : if( isset($_SERVER['HTTP_HOST']) and $_SERVER['HTTP_HOST'] != 'localhost' and $_SERVER['HTTP_HOST'] != $aUrl['host'] )
}}}

added -> '''and $_SERVER!['HTTP_HOST'] != 'localhost''''
