Deployment of a Simple Website

• We need a linux server
  • This can be an azure vm or aws ec2 instance
• We need to install webserver software
  • apache
  • nginx
• We need to copy the website Refer Here to particular
  • /var/www/html

Manual Steps

• Install nginx

sudo apt update
sudo apt install nginx -y

• Now webserver should be installed

sudo systemctl status nginx

• Now we can access the webserver over http => http://publicip
• Now lets download the website into /tmp

cd /tmp
wget https://www.free-css.com/assets/files/free-css-templates/download/page295/antique-cafe.zip

• Install unzip

sudo apt install unzip -y

• Now unzip the antique-cafe

unzip antique-cafe.zip

• Now lets copy the folder 2126_antique_cafe to /var/www/html/cafe/

sudo mv 2126_antique_cafe/ /var/www/html/cafe

• Now access http://<public-ip>/cafe

Possible Options to automate the website deployment

1. Shell Scripts:
2. Procedural in nature (i.e. define how it has to be done)
3. Are not idempotent by default
4. Solution:

#!/bin/bash
WEB_DESIGN_ZIP='https://www.free-css.com/assets/files/free-css-templates/download/page295/antique-cafe.zip'
SITE_NAME='cafe'
sudo apt update
sudo apt install nginx -y
cd /tmp
wget $WEB_DESIGN_ZIP
sudo apt install unzip -y
unzip antique-cafe.zip
sudo mv 2126_antique_cafe/ /var/www/html/$SITE_NAME

1. Configuration Management
2. Declarative in nature (what we want )
3. Most of the ansible is idempotent

• Installation overview
  
• For guided creation watch classroom video
• Installation Refer Here and Refer Here for distro based installation
• Refer Here for ubuntu based steps

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository --yes --update ppa:ansible/ansible
sudo apt install ansible -y

• To verify the installation

ansible --version

Ansible ping test

• This is used to check if the ansible control node can communicate with the node or not
• Create an inventory file with node ip in it
  
• Now execute the following command

ansible -i hosts -m ping all

* In the above case we have not passed credentials
