I have a pool of servers and keeping them the same has been a challenge. I'm running the latest CentOS 6 and I'd like them to all have the same server configurations (updates and installed modules). I don't need my files sync as I use rsync for that.

Currently I have to log into each of them and do updates and installs manually.

Thanks

Configuration Management

There are plenty of software tools that handle configuration management for you.

http://en.wikipedia.org/wiki/Configuration_management

Configuration management can be used to maintain OS configuration files.[11] Example systems include CFEngine, Bcfg2, Puppet, and Chef.

SSH

You have plenty of options, for example if you simply want to ssh into multiple servers and execute commands you could use something like Fabric

http://docs.fabfile.org/en/1.8/

Fabric is a Python (2.5 or higher) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution.
