Multi Server Installation Instructions

Requires Professional Edition License

Only the Professional edition and above supports multi server installation. If you have a standard license, please contact us to upgrade to the professional edition license. You can do so by paying the difference in price.

Install the Main Database Server

• Ensure that the MySQL server accepts remote connections. If you have root access to your server, you can do this by editing the /etc/my.cnf/ or /etc/mysql/my.cnf (the location depends on the Linux distribution). Please contact us or your hosting provider if you need help with this.
• Download and install Watch My Domains SED. Please see the basic installation instructions.
• Specify the Database Credentials and other details in Config.php
• Make sure that the $install_server_id in Config.php is blank
  
  $install_server_id = "";
• Do you want to do whois lookups from the database server? If Yes, setup the cronjob for processing lookup queues (cron.php).

Secondary Servers

• Make sure that each secondary server has a unique host name. The host name is selected when you setup the VPS or dedicated server. If you are using shared virtual hosting you cannot run multiple secondary servers from the same server.
• Download and install Watch My Domains SED.
• Specify the database credentials of the main server and other details in config.php
• Make sure that the $this_server_id in Config.php is set to "auto"
  
  $this_server_id = "auto";
• Are you using your main database server to do whois lookups? If No, make sure that one of the secondary servers uses "default" as the server id.
  
  $this_server_id = "default";
  
  This is very important and required, otherwise the first few lookup queue entries will never get processed. The rest of the servers should use "auto" as above.
• Setup the cronjob for processing lookup queues. Make sure that you use the StartIndex variable ("s") without any value for cron.php. See below.
  
  * * * * * wget -q -O /dev/null "http://www.a.com/wmdsed23/cron.php?s" >/dev/null 2>&1

  If you use PHP command-line it will be...

  * * * * * php /home/wmdsed/cron.php s >/dev/null 2>&1
