- Task-01:
- -> Create 3 EC2 instances.
- -> Install Ansible in a host server.
- -> Copy the public key of master server where Ansible is setup
- -> Now make an inventory file in the Master server and add the Private Ip address of both Node-1 and Node-2.
- -> Create a playbook to install Nginx
- -> Deploy a sample webpage using the ansible-playbook.
Ansible playbooks are amazing, as you learned yesterday. What if you deploy a simple web app using Ansible, sounds like a good project, right?
Task-01:
-> Create 3 EC2 instances.
-> Install Ansible in a host server.
- Now, login to the Master server and run this command
sudo apt-add-repository ppa:ansible/ansible
- Now install Ansible using the commands given below:
sudo apt update
sudo apt install ansible
- You can verify the installation by checking the Ansible version:
ansible --version
-> Copy the public key of master server where Ansible is setup
- Simply use
ssh-keygenin the Master as well as the Node server and copy the Master server id_rsa.pub which is a public key and paste it on authorized_keys in both the Node-1 and Node-2 servers.
- Use
vim authorized_keysto edit the file and paste the Master id_rsa.pub in it. Do it in both the Nodes.
- After this check whether you can access Node-1 or Node-2 from the Master node. Simply use
ssh (Node Private Ip address)
- We successfully accessed the Node-1 and Node-2
-> Now make an inventory file in the Master server and add the Private Ip address of both Node-1 and Node-2.
-> Try ping command using ansible to the Nodes.
- Now use the command given below to ping the nodes:
ansible -i inventory all -m ping
We can see both pings are successful which indicates servers are in active states.
-> Create a playbook to install Nginx
---
- name: Install Nginx
hosts: all
become: yes
tasks:
- name: Update apt package cache
apt:
update_cache: yes
- name: Install Nginx
apt:
name: nginx
state: present
- name: Start Nginx
service:
name: nginx
state: started
- Now use this command to run the playbook.
ansible-playbook install_nginx.yml -i (Path-of-inventory)
-> Deploy a sample webpage using the ansible-playbook.
- Create an index.html file.
<!DOCTYPE html>
<html>
<head>
<title>Our Company</title>
</head>
<body>
<h1>Welcome to Our Company</h1>
<h2>Web Site Main Ingredients:</h2>
<p>Pages (HTML)</p>
<p>Style Sheets (CSS)</p>
<p>Computer Code (JavaScript)</p>
<p>Live Data (Files and Databases)</p>
</body>
</html>
- Now, update the install_nginx.yml file.
---
- name: Install Nginx
hosts: all
become: yes
tasks:
- name: Update apt package cache
apt:
update_cache: yes
- name: Install Nginx
apt:
name: nginx
state: present
- name: Start Nginx
service:
name: nginx
state: started
enabled: yes
- name: Deploy website
copy:
src: index.html
dest: /var/www/html
- Let's run this playbook.
- Check and verify the website deployed on all the servers.
