Need help in achieving fail-over / HA in Ubuntu Server.

Hello Experts,

I have an Ubuntu Server 12.04 running a MySQL database, Python Development environment.

I have another server with exact hardware configuration as of the running live server. How can i achieve fail-over or High Availability to keep the server up all the time? Can i use any clustering solution or any other replication method? Please advise me with the best possible solution. A How to guide will help me a lot.

Thank you for your help in advance.

Best Regards
Raghav.

which do you want? you could have replication master/master setup for mysql. Since it is setup and running, transitioning to a HA/Failover will depend on what your expectations and available resources are.
i.e. setup drbd, to remove the need for shared storage ....

Hi Arnold,

Thanks for your response.

If i setup Master / Master replication for mysql, what about other applications? or do i just manage them with the help of a backup tools and redundant hardware i.e RAID and power supplies?

My requirement is to keep the server up and running in case of any failure. Do you think drbd will be a good solution for me? I have plenty of memory and 1 TB of storage in both the servers.

Also can 2-node clustering help me achieve this?

drbd could be the clustering shared storage alternative.  What does your server do, what applications?
