Install Ansible on Centos7

Installing Ansible on Centos 7 is quite straightforward. Firstly, make sure that you have epel repository installed. If not, run the command below to install EPEL repository.

yum install epel-release

Another prerequisite to install and run Ansible is Python. If you have not got Python installed, install Python before installing Ansible.

Then you can begin to install ansible.

[root@localhost /]# yum install ansible
