Webserver Failover using RH5

Jimerson · 08-12-2007, 03:26 PM

I am looking for a good way to do an apache failover using RH5.

I do not need loadbalancing. Just something so that in the event of Hardware or Software failure something that will automatically move it over with no downtime.

I have multiple servers to do this with,and they are all located on the same network so bandwidth is not an issue.

Any suggestions?

Thanks,
Jim

is something like this simple enough? http://www.onlamp.com/pub/a/onlamp/2...inuxhacks.html lots of it depends on what you consider to be a failure really. you could quite possibly mine down to the result of a db query with LVS or something, failing over if the returned data is below a certain threshold or similar. but this example will just ping the other ip.

This could be a much easier solution that what I was looking at...

I now just need to find a script that can be edited to check and see if the webserver (Port 80) is responding.

Thanks so much for your help.

James.

i would probably look at using wget or curl to dip a little further in to the config, as it's about as easy anyway. i'm sure you can adapt the script to replace a ping with a curl.
