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
