Requirements for Ansible are extremely minimal.
If you are running python 2.6 on the overlord machine (the machine that you’ll be talking to the other machines from), you will need:
If you are running less than Python 2.6, you will also need:
On the managed nodes, to use templating, you will need:
For developers, you may wish to have:
Tagged releases are available as tar.gz files from the Ansible github project page:
You can also clone the git repository yourself and install Ansible in one of two ways:
You can also install Ansible using Python Distutils:
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ sudo make install
In the near future, pre-built RPMs will be available through your distribution. Until that time you can use the make rpm command:
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ make rpm
$ sudo rpm -Uvh ~/rpmbuild/RPMS/noarch/ansible-1.0-1.noarch.rpm
Edit /etc/ansible/hosts and put one or more remote systems in it, for which you have your SSH key in authorized_keys:
192.168.1.50
aserver.example.org
bserver.example.org
Set up SSH agent to avoid retyping passwords:
ssh-agent bash
ssh-add ~/.ssh/id_rsa
Now ping all your nodes:
ansible all -m ping
Now run a live command on all of your nodes:
ansible all /bin/echo hello
Congratulations. You’ve just contacted your nodes with Ansible. It’s now time to read some of the more real-world examples, and explore what you can do with different modules, as well as the Ansible playbooks language. Ansible is not just about running commands, but you already have a working infrastructure!
