Automating the installation of a LAMP stack on Ubuntu 22.04

A LAMP stack is a combination of at least 4 different technologies used in tandem to create a fully functioning web server or web application.

The complete components of a LAMP stack include:

Linux machine (Ubuntu)
Apache web server
MySQL database
PHP

The installation of this stack will be done using a executable bash script that can be used on any debian based linux distro.

First create a file named LAMP.sh which is the file where our bash script will be stored, and will also be later executed.

Next make the file executable by going to the folder where the file is located and execute the following command

chmod -x LAMP.sh

We can now begin scripting the installation file by editing the LAMP.sh file. You can do this using a cli based file editor such as vim or nano, or you can use a gui based text editor (recommended for beginners).

#!/bin/bash

# Update the package lists for upgrades and new package installations
sudo apt-get update 

# Install MySQL server and client, Expect, Apache2, PHP, and various PHP extensions
sudo apt install -y mysql-server mysql-client expect apache2 php libapache2-mod-php php-mysql php8.2 php8.2-curl php8.2-dom php8.2-xml php8.2-mysql php8.2-sqlite3 php8.3 php8.3-curl php8.3-dom php8.3-xml php8.3-mysql php8.3-sqlite3

# Add the PPA repository for PHP maintained by Ondřej Surý
sudo add-apt-repository -y ppa:ondrej/php

# Update the package lists again to include packages from the new repository
sudo apt-get update


echo "Done with installations"

# Start the MySQL service
sudo systemctl start mysql.service

# Start the Apache2 service
sudo systemctl start apache2.service

# Start the MySQL secure installation process
# The expect command is used to automate responses to interactive prompts
sudo expect <<EOF

# Set the timeout for expect commands

# Handle the password validation prompt. If not present, skip.

    "Press y|Y for Yes, any other key for No:" {
        send "y\r"
        expect "Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:"
        send "0\r"
    }
    "The 'validate_password' component is installed on the server." {
        send_user "Skipping VALIDATE PASSWORD section as it is already installed.\n"
    }
}

expect "Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:"
send "0\r"
