Hi, I will appreciate for any suggesstion on best plan...
I am working on setting up a production environment with mirrored servers working on redhat 7.2. To balance the load, each servers have its own primary applications but all of them are mirrored. When the Ist server fails the floating alias name is tranferred to the second server manually. 2nd server then inherits the application running on 1st server. So when failover happeneds the 2nd server should run all the applications. When first server comes back on line ist servers applications are transferred to 1st server back. One of the application is using PHP and MYSQl. I have replicated databases using MYSQL replication such a way that Ist server contains master and 2nd server contains slave. This part is working properly. My question is regarding effect on MYSQL database on failover. I have to design the stratergy for failover. My intention is to keep least work during failover so that people who deal with failover do not need to bothered about database stuff. I can think about two options. When failover happeneds : 1. Make 2nd server database master, so that when 1st server comes on line it will start as slave and update databases. Then I can switch back Ist server to master again like before failover. (Or may be does mysql slave update master... or I can force updation of master again...) 2. Take a back up of 2nd server database and update ist server database when it comes on line again. Which is error prone.. I am just wondering is there any better plan .... How you guys are doing this...? Any input is appreciated...
