How to Set Up a LEMP Server on Ubuntu: Nginx, MySQL, and PHP

Introduction

A LEMP stack is a popular setup for web servers that includes Linux, Nginx (pronounced "engine-x"), MySQL, and PHP. This guide will walk you through setting up a LEMP server on an Ubuntu system, complete with best practices, configuration examples, and technical insights. Additionally, we will explore the benefits of using LinuxPatch.com for managing patches on your Linux server.

Prerequisites

Before we begin, ensure you have the following:

  • An Ubuntu server instance (24.04 LTS or later recommended)
  • Root or sudo access to the server
  • A basic understanding of the terminal and SSH

Installing and Configuring Nginx

Nginx is a high-performance web server that is known for its stability, simple configuration, and low resource consumption.

Installation

sudo apt update
sudo apt install nginx

Configuration

By default, Nginx stores its configuration files in the /etc/nginx/ directory. The main configuration file is /etc/nginx/nginx.conf. However, we often manage site-specific configurations in /etc/nginx/sites-available/ and link them to /etc/nginx/sites-enabled/.

Example Configuration

server {
    listen 80;
    server_name your_domain_or_IP;
    root /var/www/html;

    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}

Best Practices

  • Use sites-available and sites-enabled for site configurations.
  • Keep backups of configuration files before making changes.
  • Test configurations with sudo nginx -t before restarting Nginx.

Installing and Configuring MySQL 8

MySQL is a powerful, open-source relational database management system.

Installation

sudo apt update
sudo apt install mysql-server

Secure Installation

Run the security script to secure your MySQL installation:

sudo mysql_secure_installation

Creating a Database and User

sudo mysql

CREATE DATABASE example_db;
CREATE USER 'example_user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON example_db.* TO 'example_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Best Practices

  • Regularly back up your databases.
  • Use strong passwords for MySQL users.
  • Restrict MySQL user permissions to only what is necessary.

Installing and Configuring PHP 8.3

PHP is a popular server-side scripting language used for web development.

Installation

sudo apt update
sudo apt install php8.3-fpm php8.3-mysql

Configuration

The main PHP configuration file is located at /etc/php/8.3/fpm/php.ini. You can adjust various settings here, such as memory limits, upload file size limits, and more.

Example PHP Settings

memory_limit = 256M
upload_max_filesize = 50M
post_max_size = 50M

Best Practices

  • Keep PHP updated to the latest version for security and performance improvements.
  • Disable unnecessary PHP modules to improve security and performance.
  • Regularly monitor and optimize your PHP settings based on application needs.
