👁 How To Install Linux, Nginx, MySQL, PHP (LEMP stack) on Ubuntu

Introduction

The LEMP software stack serves dynamic web pages and web applications written in PHP. This is an acronym that describes a Linux operating system, with an Nginx (pronounced like “Engine-X”) web server. The backend data is stored in the MySQL database and the dynamic processing is handled by PHP.

This guide demonstrates how to install a LEMP stack on an Ubuntu server. The Ubuntu operating system takes care of the Linux portion of the stack. We will describe how to get the rest of the components up and running.

Note: This tutorial primarily targets Ubuntu 22.04 LTS with PHP 8.1. For Ubuntu 24.04 LTS users, adjust PHP version references from php8.1-fpm to php8.3-fpm throughout the commands. Also, be sure to update any PHP-FPM socket paths in your Nginx configuration (e.g., use /run/php/php8.3-fpm.sock for Ubuntu 24.04).

Unsure if something changed in mysql_secure_installation, but I ran into a strange error:

MySQL Failed! Error: SET PASSWORD has no significance for user ‘root’@‘localhost’ as the authentication method doesn’t store authentication data in the MySQL server …

To work around this, login to another session:

sudo killall -9 mysql_secure_installation

start mysql manually, then execute (substituting your own password):

ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘WhateverYouWant’;

After that, you can run mysql_secure_installation (but will have to specify the pw) to completion.

Unfortunately, this breaks the subsequent steps of passwordless login as root. I’m not sure what the remedy is, though.

after sudo mysql_secure_installation command, while setting root mysql password i get this error. anyone have idea?

… Failed! Error: SET PASSWORD has no significance for user ‘root’@‘localhost’ as the authentication method used doesn’t store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.

was unable to complete the mysql installation after multiple attempts. Turns out, 1GB of RAM is required for a droplet, and after adjusting from 512MB, it worked, please update and mention in this guide. Thanks and more power to you.

When I try to start mysql-server, I get an error and am unable to do so after installation. See the below error…

Process: 3897 ExecStart=/usr/sbin/mysqld (code=exited, status=1/FAILURE)

I think this tutorial needs to be amended since mysql_secure_installation throws an error. More info here under Step 2.
