Ansible Setup
Install Ansible#
sudo apt-get update
sudo apt-get install python-pip python-devel
sudo pip install ansible
Basics#
Inventory File#
just like a hosts file the inventory file matches ip addresses and domain names to groups
Default place is:
/etc/ansible/hosts
eg.
[example]
www.example.com
or with a non-standard (22) port
www.example.com:2222
Ansible assumes you are using key-based (password less) login
Running simple commands#
ansible example -m ping -u [username]
Just pings the server.
To check memory usage run:
ansible example -a "free -m" -u [username]
