I'm looking to share the load on our main production server across one or more additional servers. I'm also interested in the mechanics of real-time mirroring of the entire site.
On load balancing; does the slave machine need to have either or both the images directory and MW scripts/extensions installed, or is it sufficient to master/slave the respective databases?
I have looked at $wgExternalServers and $wgDBservers manual pages but wonder if there may be more extensive guidance available too.
Any pointers welcome
