Installing Ansible

You may refer installation doc from official document as well.

Requirement

Controlnodes

Controlnode is just the machine where we install the Ansible program and will contain copies of your project file including ansible playbooks. It can be a workstation, a virtual machine or a dedicated server in the environment.

• No specific HW requirements for control node server

Linux/Unix systems only (Windows not currently supported) Software

• Ansible (ansible.com/get-started)
• Python 2.6 or later
• Python2-winrm (0.2.2 or later) provides pywinrm python package

Managed Hosts

These are listed servers or nodes in the inventory – defined as static or via dynamic inventory scripts – on which Ansible commands or playbook tasks need to be executed.

Linux

• Linux managed hosts need to have Python 2 (2.4 or later) installed for most modules to work.
• python-simplejson (if old RHEL5)
• libselinux=python (if SELinux is enabled)

Windows

• Most of the modules specifically designed for Microsoft Windows hosts require PowerShell 3.0 or higher on the managed host rather than Python.
• PowerShell remoting enabled.

Installing Ansible

Check installed python version

yum list installed python

Install Ansible

yum install -y ansible 

Test installed version

[devops@ansible-box dep-install]$ ansible --version
ansible 2.3.1.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.5 (default, Aug 2 2016, 04:20:16) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]

Other Methods
Ansible can be installed via “pip”, the Python package manager. If ‘pip’ isn’t already available in your version of Python, you can get pip by:

$ sudo easy_install pip

Then install Ansible with

$ sudo pip install ansible

PPA Repo

$ sudo apt-get install ansible

If CentOS, configure EPEL repo (Extra Packages for Enterprise Linux)

sudo yum -y install epel-release
