About ansible

Ansible is a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. https://github.com/ansible/ansible

Install ansible with pip

please make sure you have install python3.

To verify whether pip is already installed for your preferred Python

python3 -m pip -V

I use the python enve environment install ansible

python3 -m venv .ansible_python # new venv environment named ansible_python

source .ansible_python/bin/activate # activate the environment

Then install the ansible

pip install ansible

Set ansible configration

vim /home/USER1/.ansible/ansible.cfg

[web_server]
# name ansible_host ansible_ssh_user ansible_ssh_private_key_file 
web1 ansible_host=192.168.1.21 ansible_ssh_user=user1 ansible_ssh_private_key_file=/home/USER1/.ssh/id_ed25519
web2 ansible_host=192.168.1.46 ansible_ssh_user=user1 ansible_ssh_private_key_file=/home/USER1/.ssh/id_ed25519
web3 ansible_host=172.xxx.xxx.xxx ansible_ssh_user=root ansible_ssh_private_key_file=/home/USER1/.ssh/id_ed25519
