|

|
||||
These steps are taken directly from the SCRATCH_INSTALL document, but they are all put together here to give a better idea of what is needed all in one place. It is assumed that you already have VICIDIAL up and running on both servers.
|
||||
|
||||
NOTE: In a multi-server setup you may want to have your database and web server on a separate machine from your Asterisk/VICIDIAL servers. Simply copy the web page directories to your new database/web server and set the AST_SERVER_conf.pl files on your VICIDIAL servers to point to that new database server. You can also have several web servers(or even load-balancing web servers) if you have more than 70 seats in one installation you may want to do that. For the web pages you just need to make sure the dbconnect.php files are configured for your database server. We have had 9 VICIDIAL servers and 2 web servers using a single database server with no problems.

THREE VICIDIAL SERVER LOAD BALANCING SETUP:

The only steps that are different as you add more load-balanced servers are steps 2 and 3:

2. The three servers need to be registered to each other as IAX2 friends:
