Install Ansible using Python installation manager pip


What is pip?

pip can be called as preferred installer program. pip is package management used to install software which written in Python.

To know how to install and configure “Ansible” you can refer to the below links.

  1. Install and configure Ansible Automation IT Tool
  2. Install Ansible using Python installation manager pip
  3. How to create a host’s Inventory using Ansible
  4. Managing Groups and User creation using Ansible
  5. Creating Logical volume based file system using Ansible


Before installing with pip let us resolve required dependencies for pip. By installing “python-setuptools” we will get “easy_install”.

# yum install python-setuptools
[root@ansible ~]# yum install python-setuptools

--> Processing Dependency: python-backports for package: python-backports-ssl_match_hostname-3.4.0.2-4.el7.noarch

--> Finished Dependency Resolution Installed:   
python-setuptools.noarch 0:0.9.8-4.el7                                   Dependency Installed:
   python-backports.x86_64 0:1.0-8.el7                                     python-backports-ssl_match_hostname.noarch 0:3.4.0.2-4.el7          Complete!

Now install wit “pip” being root user run the below command to install with “pip”.

# sudo easy_install pip

[root@ansible ~]# sudo easy_install pip

It’s time to install with “ansible” using pip installer. This will pull the required dependencies to install with “ansible”.

Create an inventory file to start the testing by running a ping test.

[ansible@ansible ~]$ cat hosts
[oel7_prod]
ansiclient1.oel7.local
ansiclient2.oel7.local
ansiclient3.oel7.local
[ansible@ansible ~]$

Run the ansible by pointing to inventory file using “-i”.

Ansible   = command
-i        = pointing to inventory file.
-m        = module ping
oel7_prod = group of hosts
[ansible@ansible ~]$ ansible -i hosts -m ping oel7_prod
ansiclient2.oel7.local | SUCCESS => {     "changed": false,      "ping": "pong" } 
ansiclient3.oel7.local | SUCCESS => {     "changed": false,      "ping": "pong" } 
ansiclient1.oel7.local | SUCCESS => {     "changed": false,      "ping": "pong" }

We have successfully installed ansible using “pip” installer and tested by running a ping over remote servers.

Conclusion:

Pip method of installation is easier to follow and we will get updated packages from pip than installing ansible from yum. Subscribe to our newsletter to keep you updated.
