How do you setup load balanced web servers?
 

Im conceptually confused on how this works. Do you setup two identical web servers and have some kind of rsync constantly running to keep them in sync?

Thanks!

You dont need exact duplicates.

I prefer nginx, if you do, its better to use nginx-upstream-fair off github versus using round-robin, you will need to manually compile nginx, if using nginx-upstream-fair

You can rsync or do a nfs share, id only do the nfs if the servers are on a dedicated gigabit switch or connected nic to nic on a 2nd set of nics.

rysnc is faster than a nfs anyways, just depends on what you want & have as described above, i use a mix of both.
