Linux servers failover setup for redundancy
I have 2 linux servers that I want to set up one as my main production server, however I would like it to failover automatically to the second server in the case of the first server going down (I dont require load balancing at this stage). Is there an accepted/recommended method of doing this out there?
Cheers M

Answer Wiki:
Install the appropriate cluster services for the distribution of Linux you are using in a active/standby configuration. You will want to have an additional nic in each server to handle cluster management and heartbeat communications between the 2 servers. If you are using shared storage for the 2 servers, it makes the process even simpler. Otherwise you will need to configure replication between them. Consult the appropriate documentation for the distro you're working with.

I highly doubt that you need to failover just operating system itself. Failover strategy could differ significantly for different kinds of applications. What services would you like to make available in failover configuration? Do you have any budget approved for the solution?
