How to Develop a LAMP Stack246

LAMP is a software stack that is commonly used for developing and hosting web applications. It consists of the following components:
Linux: The operating system
Apache: The web server
MySQL: The database server
PHP: The programming language

In this tutorial, we will show you how to set up a LAMP stack on Ubuntu 20.04.

Prerequisites

Before you begin, you will need the following:
A VPS or dedicated server running Ubuntu 20.04
A domain name pointed to your server
A text editor

Step 1: Install Apache

First, we need to install Apache. Apache is the web server that will serve our web applications.sudo apt update
sudo apt install apache2

Once Apache is installed, we can start it and enable it to start automatically on boot.sudo systemctl start apache2
sudo systemctl enable apache2

Step 2: Install MySQL

Next, we need to install MySQL. MySQL is the database server that will store our data.sudo apt update
sudo apt install mysql-server

Once MySQL is installed, we can start it and enable it to start automatically on boot.sudo systemctl start mysql
sudo systemctl enable mysql

Step 3: Install PHP

Now, we need to install PHP. PHP is the programming language that we will use to develop our web applications.sudo apt update
sudo apt install php php-mysql

Step 4: Configure Apache

Now that we have all of the components installed, we need to configure Apache to use PHP.

Open the Apache configuration file in your text editor.sudo nano /etc/apache2/sites-available/

Add the following lines to the file:<Directory /var/www/html>
AllowOverride All
Require all granted
</Directory>

Save the file and exit.

Restart Apache to apply the changes.sudo systemctl restart apache2

Step 5: Create a Database

Now that we have Apache configured, we can create a database for our web application.

Create a new database.CREATE DATABASE my_database;

Create a new user and grant them permissions to the database.CREATE USER 'my_user'@'localhost' IDENTIFIED BY 'my_password';
GRANT ALL PRIVILEGES ON my_database.* TO 'my_user'@'localhost';

Exit MySQL.exit

Step 6: Test Your LAMP Stack

Now that we have our LAMP stack set up, we can test it by creating a simple PHP script.

Create a new file in your text editor.sudo nano /var/www/html/

Add the following code to the file:<?php
$servername = "localhost";
$username = "my_user";
$password = "my_password";
$dbname = "my_database";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
$conn->close();
?>

Save the file and exit.

Visit your domain name in your web browser to test the script.

If you see the message "Connected successfully", then your LAMP stack is working properly.

Conclusion

In this tutorial, we showed you how to set up a LAMP stack on Ubuntu 20.04. This is a powerful and versatile stack that can be used to develop and host a wide range of web applications.
