Ansible Tutorial Class 1 | Ansible Lab Setup | Ansible Installation | REDAIX

In this video I am explaining Step-by-Step tutorial to install Ansible on RHEL/CentOS 8 Linux environment. We will setup a five-node environment with one controller node and two managed nodes. But before we start with the steps to install Ansible on RHEL8 or CentOS8, let us understand what is Ansible and how it works.

ANSIBLE
*********
Ansible is the leading Open Source configuration management system. It makes it easy for administrators and operations teams to control thousands of servers from central machine without installing agents on them.

Ansible is the simplest to use and manage when compared to other configuration management systems such as Puppet, Chef and Salt. It is easy to install, learn, and use. The only dependency required on the remote server is SSH service and Python.

Advantages of Ansible
**************************
Free: Ansible is an open-source tool.

Very simple to set up and use: No special coding skills are necessary to use Ansible’s playbooks (more on playbooks later).

Powerful: Ansible lets you model even highly complex IT workflows.

Flexible: You can orchestrate the entire application environment no matter where it’s deployed. You can also customize it based on your needs.

Agentless: You don’t need to install any other software or firewall ports on the client systems you want to automate. You also don’t have to set up a separate management structure.

Efficient: Because you don’t need to install any extra software, there’s more room for application resources on your server.
