failover of web server

We will implement a web system ( redhat , apache , mysql , php ) on VMware , we are considering the failover solution , I just know Heartbeat can do active/passive IP failover , I guess it will be one of method .

Could advise what is the best or the most common solution for web server failover for my case ? thanks

just a nutshell, you need to have two NICs on both VMs.

one of the NIC is for your heartbeat.

you will need some software to monitor the heartbeat, such as keepalived.

and of course your data must be centralized and available to both machines so if either one fails; your system will have the latest data.

hope it helps

That phenomenon is taken care efficiently by load balancing and that can be done by any load balancing hardware (F5) or software but if you don't want to use them .. mark me heartbeat is the best for Apache clusters as known to me! and as said above you can use "keepalive" to configure failovers.
