In this series of Ansible we’ve already seen Introduction to Ansible its uses and advantages, Ansible Architecture and how does it work, In this post we will be seeing how to Install Ansible. We will be installing Ansible in EC2 linux machine CentOS.
So let’s get started with practical.
Login to AWS Console, create 2. t2 micro system.
Step 1: Login to Ansible server and run below commands, become root user and enable password based authentication
vi /etc/ssh/sshd_config change the contents # PasswordAuthentication no => PasswordAuthentication yes service sshd restart
Step 2: Create a user devops and give sudo permission to the user
adduser devops visudo # Add in the file opened devops ALL=(ALL:ALL) NOPASSWD:ALL # To test this su devops sudo apt-get update # It should not ask for password and it should complete the command execution
Step 3: Install Ansible
sudo apt update sudo apt install software-properties-common sudo apt-add-repository --yes --update ppa:ansible/ansible sudo apt install ansible
Verify ansible version and python version
Now login to Ansible node and run Step 1 and 2 and run below step
sudo apt update sudo apt install software-properties-common sudo apt-add-repository --yes --update ppa:ansible/ansible sudo apt install python -y
Verify the installation of Python, make sure you do not install Ansible on nodes,
Login into ACS/Master as devops and configure password less login into node
ssh devops@<acspublicip> ssh-keygen ssh-copy-id devops@<nodeprivateip>
Do the following to test connectivity
sudo mv /etc/ansible/hosts /etc/ansible/hosts.backup sudo vi /etc/ansible/hosts # add node1-private ip and save the file # check by executing ansible -m ping all
Here you’re! You’ve successfully installed Ansible server and attached the node to Ansible server
