To start with we worked from the central home server by installing the following rpms:
- https://github.com/downloads/thatch45/salt/salt-0.8.9-1.el5.noarch.rpm
- https://github.com/downloads/thatch45/salt/python-zmq-2.1.7-1.el6.x86_64.rpm
- https://github.com/downloads/thatch45/salt/zeromq-2.1.7-1.el6.x86_64.rpm
$ sudo yum localinstall salt*rpm python-zmq*rpm zeromq*rpm
Now some prep work is needed here. We need to setup the hostname for the salt server in DNS and or /etc/hosts so that our clients can find it. After that we can start the master and minion on our first box.
$ sudo /sbin/chkconfig --add salt-master $ sudo /sbin/chkconfig --add salt-minion $ sudo /sbin/service salt-master start $ sudo /sbin/service salt-minion start
The next clients will only have the minion added. The master will be off as we aren't ready to deal with multi-master setups. So what can we do with salt? Well we can run cmds and such
$ sudo salt '*' cmd.run "ls -l /etc/hosts" xanadu.int.smoogespace.com: -rw-r--r--. 1 root root 209 Sep 7 14:59 /etc/hosts xanadu.int.smoogespace.com: $ sudo salt '*' user.info smooge {'xanadu.int.smoogespace.com': {'gid': 500, 'groups': ['desktop_admin_r', 'mock', 'wheel'], 'home': '/home/smooge', 'name': 'smooge', 'passwd': 'x', 'shell': '/bin/bash', 'uid': 500}} $ sudo salt '*' status.diskusage / {'xanadu.int.smoogespace.com': {'/': {'available': 13899972608, 'fstype': 'ext4', 'total': 16910295040}}}
However I then ran into some limitations. I am trying to figure out what might have caused them, but they are rather interesting:
salt '*' pkg.list_pkgs {'xanadu.int.smoogespace.com': {}} salt '*' file.get_sum /etc/passwd {'xanadu.int.smoogespace.com': 'Hash md5 not supported'}
There should be quite a bit more packages there than that, and I think md5sum is supported. I am guessing there are some packages I need to install or check in the files. Will get to that in my next blog on this.

If you're looking for a puppet-like tool entirely based on python, try bcfg2, you may even like it.
