How to Install Ansible on Linux RHEL 7 with Subscription

Description

Ansible is an extra-simple tool/framework/API for doing 'remote things'.  this command allows you to define and run a single task 'playbook' against a set of hosts.

Preparation

Before installing you are required to enable the repository that you get when buying rhel 7, and the epel repository to take ansible from a third party in the following ways:

# subscription-manager register --username kitsake --password password --auto-attach --force
# subscription-manager repos --enable rhel-7-server-ansible-2.9-rpms

Installing

# yum install ansible

Install Ansible in Linux RHEL 7

After finishing installing Ansible you can make sure that Ansible has been installed by looking at the version.

# ansible --version

Configure

let's try ansible by simply ordering a basic command to see the disk in the client.

so that ansible can run to the client, it is required that from server to client, they can log in without a password.

If you can't, you can follow the method first here: How to Setup SSH Login Without Password on RHEL 7

Continue to the next step, you must register the hosts client in the ansible settings.

# vi /etc/ansible/hosts

......

[webservers]

192.168.79.146

.....

save & exit

Trying

After you have done what follows from the explanation above. it's time for you to try it on the server that was installed earlier.

# ansible -m command -a "df -hT" -u root webservers

trying command check disk with ansible

FYI : You can see examples of playbooks in several references. I recommend that you just look here Ansible Galaxy to see more examples of playbooks.
