I have 2 webservers on 2 separate datacentres. On each datacentre, I have a loadbalancer, which redirects any web request to the appropriate webserver. Basically, Loadbalancer in DC1 (Main datacentre) will redirect all http request to webserver in DC1, while Loadbalancer in DC2 will redirect all http request to webserver in DC2. The reason is simply should the connections to DC1 be interrupted due to some fault, the roundrobin DNS that is setup will redirect all traffic to the Loadbalancer in DC2. We have managed to get this working fine. My issue is getting the webserver in DC2 to mirror the content of the webserver files, ie. html, php, etc... from the webserver in DC1. Is there any application/program/daemon that I can use to do this? Both servers will be running Fedora Core 5, with Apache2, PHP5 and MySQL 5.0, with ISPConfig as the control panel. Any help/tips/suggestions is greatly appreciated.
