I have multiple servers in WEB cluster (identical configuration for all of them, despite the IP)

How do you deploy changes in configs on multile servers?

I make the new config, then create config per every server (placing correct IP), and next:

• upload them on every server, replacing old ones (rsync over ssh)
• set on every server a job which reloads webserver at the same time (servers use ntp). - this done by issuing commands by script (to save time for logging in)
• before adding a job for server reload - there's checksum test of the config on the server) - an a notification in case of fail

How do you see such method? What should be the "professional way :) ? (I don't say my way doesn't work... it works and saves my time not used for logging on every webserver.)
