How To Install Linux, Nginx, MySQL, & PHP (LEMP Stack) on Ubuntu 22.04

Channel: Linux
Abstract: sudo apt install php8.1-fpm● php8.1-fpm.service - The PHP 8.1 FastCGI Process Manager

LEMP Stack (Linux, Nginx, MySQL and PHP ) is a popular web hosting environment for websites developed in PHP programming language. Linux is the operating system, Nginx is the popular web server and MySQL is a relational database management system used for storing data.

This tutorial will help you to install Nginx, MySQL, and PHP (LEMP Stack) on Ubuntu 22.04 Jammy Jellyfish Linux systems.

Before We Begin

Assuming that you have a running Ubuntu 22.04 Linux system with sudo (or root) privileged access.

Access your system and open a terminal. It will be good to update package manager cache and upgrade currently installed packages. To do this execute:

sudo apt update && sudo apt upgrade 

Let’s begin the LEMP (Linux, Nginx, MySQL, and PHP) stack installation on Ubuntu 22.04 Jammy Jellyfish Linux system.

Step 1 – Installing NGINX

First, we will install the Latest Nginx web server on our system. Use the following commands to add PPA for installing the latest Nginx version on your Ubuntu 22.04 Linux.

Use the following commands to install Nginx web server.

sudo apt install nginx 

This will install the Nginx web server and start the service.

Now, you need to allow webserver ports in the firewall. To allow ports 80 and 443 in the UFW firewall, execute the following commands.

sudo ufw allow 80/tcp 
sudo ufw allow 43/tcp 

Open a web browser on your system and type the server’s IP in the address bar. You will get the default Nginx server page

Nginx Default PageStep 2 – Installing PHP

First, you need to decide on the PHP version to install on your system. You can also install multiple PHP versions on a single system. Currently the repository contains PHP 5.6, PHP 7.1, 7.2, 7.3, 7.4 and PHP 8.0, 8.1. The below instruction will install PHP 8.1. Please change the version as per your requirements.

The ondrej/php ppa contains all PHP version’s for Ubuntu systems. So add this repository in your system with command below:

sudo add-apt-repository ppa:ondrej/php 

Now update the apt cache and install PHP 8.1.

sudo apt update 
sudo apt install php8.1 

This will install PHP on your Ubuntu system along with some useful PHP extensions.

Step 3 — Install and Configure PHP-FPM

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features. Nginx web server required php-fpm for processing the PHP scripts.

To install PHP-FPM, run the following command based on the installed PHP version:

sudo apt install php8.1-fpm 

Once the installation finished, check the service status:

sudo systemctl status php8.1-fpm 
● php8.1-fpm.service - The PHP 8.1 FastCGI Process Manager
     Loaded: loaded (/lib/systemd/system/php8.1-fpm.service; enabled; vendor preset: enabled)

             └─108649 "php-fpm: pool www

Apr 07 06:26:55 ubuntu2204 systemd[1]: Started The PHP 8.1 FastCGI Process Manager.

In Step 6, we will configure the Nginx virtual host with PHP-FPM to serve PHP applications.

Step 4 – Installing MySQL

The default Ubuntu repositories contain MySQL 8.0. Which can be directly installed using the package manager. To install the available MySQL server version, execute the following command.

sudo apt-get install mysql-server 

Once the installation is finished, you can secure the MySQL server by executing the following command.

sudo mysql_secure_installation 

This will ask for a few questions to secure the MySQL server.

  1. Press ‘y’ to enable validate password plugin. This will allow you to set a strict password policy for user accounts.
    VALIDATE PASSWORD COMPONENT can be used to test passwords
    and improve security. It checks the strength of password
    and allows the users to set only those passwords which are
    secure enough. Would you like to setup VALIDATE PASSWORD component?
    Press y|Y for Yes, any other key for No: y
  2. Chose the password complexity level. Read all 3 options and choose one. For production servers we recommend to choose STRONG policy.
    LOW    Length >= 8
    MEDIUM Length >= 8, numeric, mixed case, and special characters
    STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
    Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1
  3. Enter a new password and re-enter it. Make sure it matches the complexity level as described above.
    New password: *************
    Re-enter new password: *************
  4. Press ‘y’ to continue with provided password.
    Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
  5. Remove default anonymous users from MySQL server:
    Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
  6. Disable root login from remote systems
    Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
  7. Remove test database form MySQL created by default during installation.
    Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
  8. Reload all privileges to apply above changes immediately.
    Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

You have secured the MySQL server in the LAMP stack on Ubuntu 22.04 Linux system.

Remember that the above password set for the root accounts is used for remote users only. To log in from the same system, just type mysql on terminal.

sudo mysql 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 14
Server version: 8.0.28-0ubuntu4 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.


Type ‘quit’ to exit from the MySQL shell and return to the system terminal.

Step 5 – Installing Additional Packages

You may also need to install modules like MySQL and other extensions for PHP based on the application requirements. Use the following command to find our available PHP extensions.

sudo apt search php8.1-* 

The above command will list all available PHP7 modules for installation, Let’s begin the installation of modules.

sudo apt install php8.1-mysql php8.1-curl php8.1-xml 

You may also need to install other required PHP extensions on your system.

Step 6 — Configure Nginx VirtualHost

Finally, do the configuration of the Nginx virtual host. For this example, we are editing the default configuration file.

sudo nano /etc/nginx/sites-enabled/default 

and make changes as below.

server {
        listen   80;

        root /var/www/;
        index index.php;

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

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php8.1-fpm.sock;


In the above configuration file, look for location ~ \.php$ section. Which is required to service PHP scripts via Nginx server.

You have to do the same changes in all VirtualHosts configured.

Step 7 – Verify Setup

You have successfully completed the installation of Nginx, MySQL, and PHP on the Ubuntu 22.04 Linux system. To verify the PHP integration with Nginx, create a PHP script (example: info.php) on the website document root and write the below content.

<?php phpinfo(); ?>123<?php   phpinfo();?>

Now access this file in the web browser. It will so all the details about versions and installation.
