Install LEMP Stack on Ubuntu 24.04

Install Nginx, MariaDB, PHP 8, PHP-FPM, and phpMyAdmin on Ubuntu 24.04 with optional multi-PHP support and Nginx virtual hosts.

This guide walks through a full LEMP stack setup on Ubuntu 24.04 using Nginx, MariaDB, PHP 8, PHP-FPM, and phpMyAdmin.

By the end, you will have:

a sudo-enabled admin user
updated system packages
SSH on a custom port
UFW enabled
systemd-resolved configured
Nginx, MariaDB, PHP, and phpMyAdmin installed
optional multi-PHP support
a dedicated PHP-FPM pool and Nginx virtual host for a site

Create a Sudo User

Skip this step if you already have a working sudo user.

Create a new user:

adduser newuser

Grant sudo access:

sudo usermod -aG sudo newuser

Switch to the new user and verify sudo works:

su - newuser
sudo whoami

If the command returns root, sudo is configured correctly.

Update Packages

Update package metadata and upgrade installed packages:

sudo apt update && sudo apt upgrade

Change the SSH Port

Edit the SSH server config:

sudo vim /etc/ssh/sshd_config

Set a custom port and disable root login:

Port 52225
PermitRootLogin no

Reload the SSH service:

sudo systemctl daemon-reload
sudo systemctl restart ssh

Enable the Firewall

Install UFW:

sudo apt install ufw

Allow HTTP, HTTPS, and your custom SSH port:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw allow 52225/tcp

Enable the firewall:

sudo ufw enable

Check active rules:

sudo ufw status

Connect over the new SSH port:

ssh -p 52225 user@your_server_ip

Enabling the firewall can drop the current SSH session. Reconnect using the new port if needed.

Configure DNS Resolver

Install and enable systemd-resolved:

sudo apt install systemd-resolved
sudo systemctl enable systemd-resolved
sudo systemctl start systemd-resolved
sudo systemctl status systemd-resolved

Edit the resolver config:

sudo vim /etc/systemd/resolved.conf

Use Cloudflare and Quad9:

[Resolve]
DNS=1.1.1.1 1.0.0.1 2606:4700:4700::1111 2606:4700:4700::1001
FallbackDNS=9.9.9.9 149.112.112.112 2620:fe::fe 2620:fe::9
DNSOverTLS=opportunistic

Point resolv.conf at the stub resolver and restart:

sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
sudo systemctl restart systemd-resolved

Check resolver status:

resolvectl status

Generate an SSL Certificate

Create a self-signed certificate for local testing or internal use:

sudo openssl req -x509 -newkey rsa:2048 -nodes -keyout /etc/ssl/private/default.key -out /etc/ssl/certs/default.crt -days 3650

Install PHP 8 and PHP-FPM

Check the PHP packages available in the Ubuntu repositories:

sudo apt search php | egrep '^php[0-9]'

Install PHP 8.3 and common extensions:

sudo apt install php8.3 php8.3-cli php8.3-fpm php8.3-common php8.3-mysql php8.3-zip php8.3-gd php8.3-mbstring php8.3-curl php8.3-xml php8.3-bcmath php8.3-gmp

Those packages cover common dependencies for WordPress and similar PHP applications.

Optional: Install Multiple PHP Versions

If you want to run multiple PHP versions, add the Ondrej Sury PHP repository:

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

Install both PHP 7.4 and PHP 8.3:

sudo apt install php7.4 php7.4-cli php7.4-fpm php7.4-common php7.4-mysql php7.4-zip php7.4-gd php7.4-mbstring php7.4-curl php7.4-xml php7.4-bcmath php7.4-gmp
sudo apt install php8.3 php8.3-cli php8.3-fpm php8.3-common php8.3-mysql php8.3-zip php8.3-gd php8.3-mbstring php8.3-curl php8.3-xml php8.3-bcmath php8.3-gmp

Configure PHP-FPM Pools

Edit the PHP 8.3 pool:

sudo vim /etc/php/8.3/fpm/pool.d/www.conf

Use:

[php-fpm-8.3]
user = www-data
group = www-data

listen = /run/php/php8.3-fpm.sock

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Restart the service:

sudo systemctl restart php8.3-fpm

If you also installed PHP 7.4, edit its pool:

sudo vim /etc/php/7.4/fpm/pool.d/www.conf

Use:

[php-fpm-7.4]
user = www-data
group = www-data

listen = /run/php/php7.4-fpm.sock

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Restart PHP 7.4 FPM:

sudo systemctl restart php7.4-fpm

Disable commonly abused functions:

sudo vim /etc/php/8.3/fpm/php.ini
sudo vim /etc/php/7.4/fpm/php.ini

Set:

disable_functions = exec,passthru,shell_exec,system,proc_open,popen

Enable OPcache:

[opcache]
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.use_cwd=1
opcache.validate_timestamps=1
opcache.revalidate_freq=60
opcache.save_comments=1

Restart both FPM services if you configured both versions:

sudo systemctl restart php8.3-fpm
sudo systemctl restart php7.4-fpm

Install Nginx

You can use either the Ubuntu package or the official Nginx repository.

Install from the Ubuntu repository:

sudo apt install nginx
sudo ufw allow 'Nginx Full'
sudo ufw reload
sudo systemctl enable nginx
sudo systemctl start nginx
sudo systemctl status nginx

If you want the latest Nginx from the official repository, add the signing key:

curl -fsSL https://nginx.org/keys/nginx_signing.key | gpg --dearmor | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

Add the stable repo:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list

Or add the mainline repo:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list

Then install and start it:

sudo apt update
sudo apt install nginx
sudo systemctl enable nginx
sudo systemctl start nginx
sudo systemctl status nginx

Prepare the site config directories:

sudo mkdir -p /etc/nginx/sites-enabled
sudo mkdir -p /etc/nginx/sites-available

Back up the current config:

sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak

Edit the main config:

sudo vim /etc/nginx/nginx.conf

Replace it with:

user www-data;
worker_processes auto;

sudo vim /etc/nginx/sites-available/default

Use:

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  listen 443 ssl default_server;
  listen [::]:443 ssl default_server;
  server_name _;

  ssl_certificate /etc/ssl/certs/default.crt;
  ssl_certificate_key /etc/ssl/private/default.key;

  root /usr/share/nginx/html;
  index index.html index.htm index.php;

  location / {
    try_files $uri $uri/ /index.php?$args;

    location ~ \.php$ {
      root /usr/share/nginx/html;
      fastcgi_pass unix:/run/php/php8.3-fpm.sock;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include fastcgi_params;
    }
  }

  location ~ /\.ht {
    deny all;
  }

  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
    root /usr/share/nginx/html;
  }
}
