Ansible can only be installed in Linux system. Although we can connect Windows machine in Ansible inventory.
Update System
Debian-Based System (Ubuntu, Debian)
sudo apt-get update
sudo apt-get-upgrade
RHEL-Based system (CentOS, RGEL, Fedora)"
If you are using RHEL-Based system then the command will be
sudo yum update
Install Python
Debian-Based System (Ubuntu, Debian)
sudo apt-get install python3
RHEL-Based system (CentOS, RGEL, Fedora)"
If you are using RHEL-Based system then the command will be
sudo yum install python3
Install Ansible
Debian-Based System (Ubuntu, Debian)
sudo apt-get install ansible
RHEL-Based system (CentOS, RGEL, Fedora)"
If you are using RHEL-Based system then the command will be
sudo yum install ansible
Verify the version
ansible --version
Configure Ansible
Generally we will be modifying /etc/ansible/ansible.cfg file change/update any Ansible configuration.
We can also add inventory file in /etc/ansible location. To start with we can add a file name hosts in the /etc/ansible folder. Content of the file may look something like this:
[webserver]
192.168.1.0
196.168.1.11
And then update the /etc/ansible/ansible.cfg file:
inventory = /etc/ansible/hosts
Now ansible is installed and ready to use.
