Distro: CentOS/ Ubuntu Linux /Debian/ RHEL/
Jinja2: Friendly designing language used specifically for python
PyYAML: Python programming language emitter and parsing component
parmiko: SSHv2 protocol library which is python nativeSteps to Install Ansible
Given below are the steps required to install the Ansible:Install Ansible Using YUM
Step 1: Form a universal id on collective machines, for Example, ansible with SUDO privileges. All ids involved in automation tasks can use this ID.
# passwd ansible
Both the machines execute the above-listed set of steps. This happens when the end system is to be restarted
# systemctl restart ssh
Step 4: For achieving passwordless authentication the below list of steps has to be performed. initially add the Ansible user to the /etc/sudoers file on both the machines which finely allows Ansible users to execute all commands which need root privileges. Terminal exit once the needed elements are added.
Step 5: Switch out to user Ansible.
Control Machine su – ansible AND Target Machine su – ansible
Step 6: Wget has to be installed in both the machines involved.

Step 7: Enabling EPEL repo allows us to install ansible on the control machine. Add-on software packages can be installed using Fedora.
$ ansible –version
Step 8: Edit the chúng tôi file and enable the inventory file parameter on the Control machine.
$ sudo vi /etc/ansible/ansible.cfg
Step 9: Target machines are tracked and managed using inventory in Ansible. Usually, this file is present in /etc/ansible/hosts and allows to be edited. Every needed machine is associated with these groups. A group name and square bracket are applied within each and every group. Multiple groups are tagged in a server.
Step 10: To execute the webservers groups allow execution of the below-listed ansible commands. Ping allows a particular function to be tested and also whether the host systems can be established as the connection parameters mentioned in the inventory file.
$ ansible webservers –m ping
