Re: Second apache as fallback server

[Bob <bobnlinux@xxxxxxxxx>]

Hello Yehuda,

Thanks for your response.

I'm still confused with log files. Say load balancer now put us on hot standby node. We already have some logs ( both access and error) at master node. How can we get all those logs as soon as we are on hot standby ?  We need unique log files for production clusters.

I wonder how cloud cluster address this issue !!

The challenge is to maintain unique web server log across the nodes. Any clue about that ?
Again for pages which send emails, all nodes must have running postfix with same domain.
I'm also wondering how to do that.

To keep the configuration the same, look at Puppet (https://puppetlabs.com/puppet/puppet-open-source) or Chef (chef.io).

For log files, we use rsync to put all the logs on one machine after they are rotated. That means it may take 24 hours before the logs are received, but on servers that don't have shared storage, that it probably the easiest way.
