Cross server configuration script

config_update.sh

#!/bin/bash

# You can synchronize the configuration of multiple servers using git and this very small script.
# Just add your servers in a file called "serverlist.txt" (one per line) and
# configure git on the $REMOTE_DIRECTORY_CONFIG. Personnaly, I use the root of the server (/)
# You can also use git hook post-update to run a command after the update 
# of the config files if you wish.

SERVERS_FILE="serverlist.txt"
REMOTE_DIRECTORY_CONFIG="/"
POST_UPDATE_COMMAND="echo update ok"

servers=( $( cat $SERVERS_FILE ) )
for  server in ${servers[*]}
do
	ssh $server "cd $REMOTE_DIRECTORY_CONFIG && git pull && $POST_UPDATE_COMMAND"
	echo "Done with $server"
done
