A combination of Linux, Apache, MySQL, and PHP is known as LAMP stack is the popular web hosting environment for the PHP based application. Here Linux is an operating system, Apache is the popular web server developed by Apache Foundation, MySQL is relational database management system used for storing data and PHP is the widely used programming language.
This article will help you to Install Apache 2.4, MySQL 8.0 and PHP 7.4 on Ubuntu 20.04 LTS (Focal Fossa) system. Let’s begin the installation of LAMP stack your Ubuntu machine.
You must have root or sudo privileged user access to your Ubuntu 20.04 system. Login to your Ubuntu system using GUI for Desktop and SSH for the server edition.
Now upgrade current packages to latest version.
sudo apt update sudo apt upgrade
Follow the initial server setup instruction to get ready your system for working.
Step 1 – Installing PHP
PHP 7.4 packages are available under the default repositories on Ubuntu 20.04 LTS. To install PHP on your system, update apt index and then install it on your system.
sudo apt update sudo apt install -y php7.4
Also install additional PHP modules required for your application.
sudo apt install php7.4-curl php7.4-gd php7.4-json php7.4-mbstring php7.4-xml
Step 2 – Installing Apache2
Next, you need to install Apache2 package on your system. The Apache packages are are available under the default apt repositories. You also need to install libapache2-mod-php module to work PHP with Apache2.
Type below commands to install it:
sudo apt install apache2 libapache2-mod-php7.4

Step 3 – Installing MySQL Server
The default Ubuntu 20.04 apt repositories contains MySQL server 8.0. Finally, install mysql-server packages for the MySQL database. Also, install the php-mysql package to use MySQL support using PHP. Use the following command to install it.
sudo apt install mysql-server php7.4-mysql
The installer will prompt for the root password, This password will work for your MySQL root user. After installing MySQL execute the following command for initial settings of MySQL server. You will see that script will prompt for more settings than earlier MySQL versions like password validation policy etc.
sudo mysql_secure_installation Securing the MySQL server deployment. Connecting to MySQL using a blank password. 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 There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary filePlease enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2 Please set the password for root here.New password: Re-enter new password: Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.Remove anonymous users? (Press y|Y for Yes, any other key for No) : y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately.Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y Success. All done!
Step 4 – Installing phpMyAdmin (optional)
phpMyAdmin provides a user friendly web interface to manage MySQL database server. You can install phpMyAdmin on Ubuntu 20.04 by executing the following command:
sudo apt install phpmyadmin
The installation process will prompt to select web server to configure. Select “Apache” as web server to run phpMyAdmin.
Next, this will prompt to create database for phpMyAdmin and prompt for the administrative user access details. Complete all steps to finish phpMyAdmin installation.
Step 5 – Manage Services
We have done with the installation of LAMP stack on Ubuntu 20.04 LTS system. The below commands will help you to start/stop or restart Apache and MySQL services running with systemd.
To restart Apache and MySQL services, type:
sudo systemctl restart apache2 sudo systemctl restart mysql
To start Apache and MySQL services, type:
sudo systemctl start apache2 sudo systemctl start mysql
To stop Apache and MySQL services, type:
sudo systemctl stop apache2 sudo systemctl stop mysql
Step 6 – Adjusting Firewall Rules
You can directly provide a service name like “http” or “https” to allow. The firewalld uses /etc/services file to determine the corresponding port of the service.
sudo firewall-cmd --permanent --add-service=http sudo firewall-cmd --permanent --add-service=https sudo firewall-cmd --reload
Step 7 – Test Setup
After completing all setup. Let’s create a info.php file website document root with following content.
sudo echo "<?php phpinfo(); ?>" > /var/www/html/info.php
Now access this file in web browser. You will see the screen like below with all details of PHP on server.
Also access the phpMyAdmin
