How to Install LAMP Stack on Ubuntu 22.04 Server/Desktop

This tutorial is going to show you how to install LAMP stack on Ubuntu 22.04 LTS. A software stack is a set of software tools bundled together. LAMP stands for Linux, Apache, MariaDB/MySQL, and PHP, all of which are open source and free to use.

It is the most common software stack that powers dynamic websites and web applications.

  • Linux is the operating system.
  • Apache is the web server.
  • MariaDB/MySQL is the database server.
  • PHP is the server-side scripting language responsible for generating dynamic web pages.


To follow this tutorial, you need an Ubuntu 22.04 OS running on your local computer or on a remote server.

If you are looking for a virtual private server (VPS), I recommend Kamatera VPS, which features:

  • 30 days free trial.
  • Starts at $4/month (1GB RAM)
  • High-performance KVM-based VPS
  • 9 data centers around the world, including the United States, Canada, UK, Germany, The Netherlands, Hong Kong, and Isreal.

Follow the tutorial linked below to create your Linux VPS server at Kamatera.

Once you have a VPS running Ubuntu 22.04, follow the instructions below.

And if you need to set up LAMP stack with a domain name, I recommend buying domain names from NameCheap because the price is low and they give whois privacy protection free for life.

Step 1: Update Software Packages

Before we install the LAMP stack, it’s a good idea to update the repository and software packages. Run the following commands on your Ubuntu 22.04 OS.

sudo apt update

sudo apt upgrade

Step 2: Install Apache Web Server

Enter the following command to install Apache Web server. The apache2-utils package will install some useful utilities like Apache HTTP server benchmarking tool (ab).

sudo apt install -y apache2 apache2-utils

After it’s installed, Apache should be automatically started. Check its status with systemctl.

systemctl status apache2

Sample output:

 apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2022-04-11 11:31:31 CST; 2s ago
    Process: 53003 ExecStart=/usr/sbin/apachectl start (code=exited, status=0/SUCCESS)
   Main PID: 53011 (apache2)
      Tasks: 55 (limit: 19072)
     Memory: 6.4M
     CGroup: /system.slice/apache2.service
             ├─53011 /usr/sbin/apache2 -k start
             ├─53012 /usr/sbin/apache2 -k start
             └─53013 /usr/sbin/apache2 -k start

Hint: If the above command doesn’t quit immediately, you can press Q key to gain back control of the terminal.

If it’s not running, use systemctl to start it.

sudo systemctl start apache2

It’s also a good idea to enable Apache to automatically start at system boot time.

sudo systemctl enable apache2

Check Apache version:

apache2 -v


Server version: Apache/2.4.52 (Ubuntu)
Server built: 2022-03-25T00:35:40

Now type in the public IP address of your Ubuntu 22.04 server in the browser address bar. You should see the “It works!” Web page, which means Apache Web server is running properly. If you are installing LAMP on your local Ubuntu 22.04 computer, then type or localhost in the browser address bar.


If the connection is refused or failed to complete, there might be a firewall preventing incoming requests to TCP port 80. If you are using iptables firewall, then you need to run the following command to open TCP port 80.

sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT

If you are using the UFW firewall, then run this command to open TCP port 80.

sudo ufw allow http

Now we need to set www-data (Apache user) as the owner of document root (otherwise known as web root). By default it’s owned by the root user.

sudo chown www-data:www-data /var/www/html/ -R

By default, Apache uses the system hostname as its global ServerName. If the system hostname can’t be resolved in DNS, then you will probably see the following error after running sudo apache2ctl -t command.

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using Set the 'ServerName' directive globally to suppress this message

To solve this problem, we can set a global ServerName in Apache. Use the Nano command-line text editor to create a new configuration file.

sudo nano /etc/apache2/conf-available/servername.conf

Add the following line in this file.

ServerName localhost

Save and close the file. To save a file in Nano text editor, press Ctrl+O, then press Enter to confirm. To exit, press Ctrl+X. Then enable this config file.

sudo a2enconf servername.conf

Reload Apache for the change to take effect.

sudo systemctl reload apache2

Now if you run the sudo apache2ctl -t command again, you won’t see the above error message.

Step 3: Install MariaDB Database Server

MariaDB is a drop-in replacement for MySQL. It is developed by former members of MySQL team who are concerned that Oracle might turn MySQL into a closed-source product. Enter the following command to install MariaDB on Ubuntu 22.04.

sudo apt install mariadb-server mariadb-client

After it’s installed, MariaDB server should be automatically started. Use systemctl to check its status.

systemctl status mariadb


● mariadb.service - MariaDB 10.6.7 database server
     Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
     Active: active (running) since Fri 2022-04-10 14:19:16 UTC; 18s ago
       Docs: man:mysqld(8)
   Main PID: 9161 (mysqld)
     Status: "Taking your SQL requests now..."
      Tasks: 31 (limit: 9451)
     Memory: 64.7M
     CGroup: /system.slice/mariadb.service
             └─9161 /usr/sbin/mysqld

Hint: If the above command doesn’t immediately quit after running. You need to press “q” to make it quit.

If it’s not running, start it with this command:

sudo systemctl start mariadb

To enable MariaDB to automatically start at boot time, run

sudo systemctl enable mariadb

Now run the post-installation security script.

sudo mysql_secure_installation
  • When it asks you to enter MariaDB root password, press Enter key as the root password isn’t set yet.
  • Don’t switch to unix_socket authentication because MariaDB is already using unix_socket authentication.
  • Don’t change the root password, because you don’t need to set root password when using unix_socket authentication.


Next, you can press Enter to answer all remaining questions, which will remove anonymous user, disable remote root login and remove test database. This step is a basic requirement for MariaDB database security. (Notice that Y is capitalized, which means it is the default answer. )


By default, the MaraiDB package on Ubuntu uses unix_socket to authenticate user login, which basically means you can use username and password of the OS to log into MariaDB console. So you can run the following command to log in without providing MariaDB root password.

sudo mariadb -u root

To exit, run


Check MariaDB server version information.

mariadb --version

As you can see, we have installed MariaDB 10.6.7.

mariadb Ver 15.1 Distrib 10.6.7-MariaDB, for debian-linux-gnu (x86_64) using EditLine wrapper

Step 4: Install PHP8.1

At the time of this writing, PHP8.1 is the latest stable version of PHP and has a minor performance edge over PHP8.0. Enter the following command to install PHP8.1 and some common PHP modules.

sudo apt install php8.1 libapache2-mod-php8.1 php8.1-mysql php-common php8.1-cli php8.1-common php8.1-opcache php8.1-readline php8.1-mbstring php8.1-xml php8.1-gd php8.1-curl

Enable the Apache php8.1 module then restart Apache Web server.

sudo a2enmod php8.1

sudo systemctl restart apache2

Check PHP version information.

php --version


PHP 8.1.2 (cli) (built: Apr 7 2022 17:46:26) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
     with Zend OPcache v8.1.2, Copyright (c), by Zend Technologies

To test PHP scripts with Apache server, we need to create a info.php file in the document root directory.

sudo nano /var/www/html/info.php

Paste the following PHP code into the file.

<?php phpinfo(); ?>

To save a file in Nano text editor, press Ctrl+O, then press Enter to confirm. To exit, press Ctrl+X. Now in the browser address bar, enter server-ip-address/info.php. Replace server-ip-address with your actual IP. If you follow this tutorial on your local computer, then type or localhost/info.php.

You should see your server’s PHP information. This means PHP scripts can run properly with Apache web server.


How to Run PHP-FPM with Apache

There are basically two ways to run PHP code with Apache web server:

  • Apache PHP module
  • PHP-FPM.

In the above steps, the Apache PHP8.1 module is used to handle PHP code, which is usually fine. But in some cases, you need to run PHP code with PHP-FPM instead. Here’s how.

Disable the Apache PHP8.1 module.

sudo a2dismod php8.1

Install PHP-FPM.

sudo apt install php8.1-fpm

Enable proxy_fcgi and setenvif module.

sudo a2enmod proxy_fcgi setenvif

Enable the /etc/apache2/conf-available/php8.1-fpm.conf configuration file.

sudo a2enconf php8.1-fpm

Restart Apache for the changes to take effect.

sudo systemctl restart apache2

Now if you refresh the info.php page in your browser, you will find that Server API is changed from Apache 2.0 Handler to FPM/FastCGI, which means Apache web server will pass PHP requests to PHP-FPM.


Congrats! You have successfully installed LAMP stack (Apache, MariaDB and PHP8.1) on Ubuntu 22.04. For your server’s security, you should delete info.php file now to prevent prying eyes.

sudo rm /var/www/html/info.php

    Nice write-up.
    Would be great to include setting up FPM for separate users, like in a shared host situation. I believe this would be very common.

    Hi, Just completed above. Nice and easy to follow. Worked fine till very last check for ServerAPI (FPM/FastCGI). I didn’t see this. It remained as “Apache 2.0 Handler”. I did move the info.php file into web site beneath /var/www/html where it was accessed (ie. the info.php was used successfully). Should it have found it? J

      Checking out the apache log /var/log/apache2/access.log or /var/log/apache2/error.log may help.

        Hi Thanks for suggestion, Logs did identify problem- “AH01071: Got error ‘Primary script unknown”.

  • This was very informative, thank you!

  • Great tutorial. Your list of packages to get for the php8 install helped me solve a problem I was having with LAMP. I think I had missed 3 or 4 when installing each of A M P individually.

    Many thanks.

  • Thank you for sharing the knowledge I needed.
