The LEMP stack (Linux, Nginx, MySQL, PHP) is a popular solution for hosting dynamic websites and applications. In this tutorial, you will learn how to install and configure the LEMP stack on Ubuntu 22.04.
Step 1: Update Your System
Before starting the installation process, ensure your system is up-to-date by running the following command:
sudo apt update && sudo apt upgrade
Step 2: Install Nginx
Nginx is a high-performance web server used in the LEMP stack. Install it using the following command:
sudo apt install nginx
After installation, start and enable Nginx:
sudo systemctl start nginx
sudo systemctl enable nginx
Step 3: Install MySQL
MySQL is the database server used in the LEMP stack. To install MySQL, run the following command:
sudo apt install mysql-server
Once installed, run the security script to enhance MySQL security:
sudo mysql_secure_installation
Step 4: Install PHP
PHP is a server-side scripting language that processes dynamic content. Install PHP and the necessary extensions:
sudo apt install php-fpm php-mysql
PHP-FPM (FastCGI Process Manager) allows Nginx to handle PHP requests efficiently.
Step 5: Configure Nginx to Use PHP
To configure Nginx to process PHP files, open the default server block file:
sudo nano /etc/nginx/sites-available/default
Find the following section and modify it:
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}
Save the file and restart Nginx:
sudo systemctl restart nginx
Step 6: Test PHP
To verify that PHP is working with Nginx, create a PHP info file:
sudo nano /var/www/html/info.php
Add the following code:
<?php phpinfo(); ?>
Save the file and visit http://your_server_ip/info.php
to confirm PHP is working correctly.
