There probably several ways of doing this.

To start with have a look at ‘host\_vars’ - you can set variables for each machine in your inventory: [http://docs.ansible.com/intro\_inventory.html#host-variables](http://docs.ansible.com/intro_inventory.html#host-variables)

You will probably find very soon after that you want to set the same variables for groups of servers, so read about group vars as well (on the same page).

Hope this helps,

Jon
