Install & Configure Ansible in RHEL 8 (CentOS 8) | Ansible Configuration in Linux | Nehra Classes

Install & Configure Ansible in RHEL 8 (CentOS 8): ================================================= Ansible is an open-source software provisioning, configuration management and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It includes its own declarative language to describe system configuration. Ansible was written by Michael DeHaan and acquired by Red Hat in 2015. Ansible is agentless, temporarily connecting remotely via SSH or Windows Remote Management (allowing remote PowerShell execution) to do its tasks. On RHEL 8, enable the official Red Hat repository, for the corresponding Ansible version that you want to install as shown in this article. DO NOT USE PIP ON RHEL 8!. Step 1: Installing Python3 Usually, RHEL 8 and CentOS 8 will come with Python3 already installed by default. However, If for whatever reason Python3 is not installed, install it using the following dnf commands. Make sure you must log in as normal user with Sudo privileges. visudo vikasnehra su - vikasnehra $ sudo dnf update $ sudo dnf install python3 To verify that indeed you have python3 installed, run the command. $ python3 -V Step 2: Installing PIP – The Python Package Installer Pip is a Python’s package manager, which is also comes preinstalled, but again, in case Pip is missing on your system, install it using the command. $ sudo dnf install python3-pip Step 3: Installing the Ansible Automation Tool With all the prerequisites met, install ansible by running the command on CentOS 8. pip3 install ansible --user On RHEL 8, enable the Ansible Engine repository to install corresponding Ansible version as shown, subscription-manager repos --enable ansible-2.8-for-rhel-8-x86_64-rpms dnf -y install ansible To check the version of Ansible, run. ansible --version Step 4: Testing the Ansible Automation Tool To test ansible, first ensure that ssh is up and running. $ sudo systemctl status sshd Next, we need to create the hosts file in the /etc/ansible directory to define host machines. $ sudo mkdir /etc/ansible $ cd /etc/ansible $ sudo vim hosts The hosts the file will be the inventory where you will have all your remote nodes. Now open hosts file with your favorite editor and define the remote node as shown. [web] 192.168.1.109 Next, generate SSH keys from which we will copy the public key to the remote node. $ ssh-keygen To copy the generated SSH key to the remote node run the command. $ ssh-copy-id [email protected] Now use Ansible to ping the remote node as shown. $ ansible -i /etc/ansible/hosts web -m ping We have managed to successfully install and test Ansible on RHEL/CentOS 8 Linux distribution.
