If you're at the point where you have to run the same commands on multiple servers, you should really be looking at puppet or cfengine. They really reduce the need to be interacting with the servers, and ensure consistency (and by consistency I mean "fewer fat fingers").

I even gave a presentation mentioning the latter ( http://www.muug.mb.ca/meetings/lamp_tuning_seanwalberg.pdf) and have written about the former (http://m.linuxjournal.com/article/10046)
