* Ansible Provisioning :*
output :
Example : Setting up Ansible Provisioning for Nginx Installation on Vagrant:
Step 1:
Install Ansible on Your Machine :
sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible
Step 2:
Go to your server's /etc/hosts file and add the hostname and the IP address of the host:
hostname : vagrant
hostname -I : 10.0.2.15.
Step 3:
As Ansible works on the agentless architecture of using SSH to communicate with its hosts, set-up the ssh keys:
ssh-keygen
cat ~/.ssh/id_rsa.pub
ssh-copy-id root@10.0.2.15.
Step 4:
Add the Vagrant SSH Key inside authorized_keys:
sudo nano ~/.ssh/authorized_keys
Step 5:
Configure Ansible Hosts , Edit the /etc/ansible/hosts file and add the hostname:
sudo nano /etc/ansible/hosts
vagrant
Step 6:
Verify Connectivity:
ansible -m ping all
output --->
vagrant | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
Step 7:
Write Ansible Playbook for Nginx Installation:
vi nginx-playbook.yml
Step 8:
Run the Ansible Playbook:
ansible-playbook nginx-playbook.yml
output :
