[RADIATOR] radiator secondary server.

[--shashi--]

Hi Roy,

There are some situations to consider.

1. If your radius is just for authentication, you can setup identical 
services in 2 servers, and use some sort of a copy/hot backup in mysql 
to replicate the primary database to the secondary database.

2. If you use radius for accounting also, then when your primary server 
is down, all accounting is done on the secondary server, and when the 
primary comes up, it automatically shifts to the primary server. If your 
setup deals with user accounting and balances (voip, prepaid isp minutes 
etc), then you will end up with 2 different databases with different 
balances and usage records.

The best way is to use one dedicated mysql server for database, and run 
2 radius servers, keeping the database same. You can backup the database 
periodically using backup tools.
