A LAMP stack is short form of Linux, Apache, MySQL and PHP. Here, L means Linux operating system, A for Apache web server, M is for MySQL database, P for PHP programming language. In this guide, we’ll install Apache 2.4, MySQL 8.0 and PHP 7.4 (LAMP) on Ubuntu 20.04 LTS (Focal Fossa) system.
You must have root user or user with sudo privileges.
Upgrade current packages to latest version.
sudo apt update
sudo apt upgrade
Step 1 – Installing Apache
Installing Apache is a pretty straightforward process. We will install Apache from default Ubuntu repositories using apt package manager. On Debian based distributions, the Apache package and the service is called
sudo apt install apache2
Step 2 — Installing MySQL
MySQL is a popular database management system used within PHP environments. The default Ubuntu repositories includes MySQL server 8.0. Use the following command to install it.
sudo apt install mysql-server
Once the installation is finished, it’s recommended that you run a security script that comes pre-installed with MySQL. This script will remove some insecure default settings and lock down access to your database system. Run the below command:
You will be prompt for few questions as given below, select the appropriate options:
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 file Please 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 3 – Installing PHP
At this point, you have installed Apache and MySQL. Now we need PHP to process code to display dynamic content to user. 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. It also required to install
libapache2-mod-php to enable Apache to handle PHP files.
sudo apt update
sudo apt install php libapache2-mod-php php-mysql
Step 4 – Adjusting the Firewall
After Apache installation make sure that your firewall allows HTTP and HTTPS traffic. You can get list of ufw profile list by typing :
sudo ufw app list
Available applications: Apache Apache Full Apache Secure OpenSSH
Allow incoming HTTP and HTTPS traffic for this profile:
sudo ufw allow in "Apache Full"
Step 5 – Manage Services
Now we completed LAMP installation steps. We will see some basic management commands.
To stop Apache and MySQL service you can run :
sudo systemctl stop apache2
sudo systemctl stop mysql
You can again start service by type :
sudo systemctl start apache2
sudo systemctl start mysql
To do Restart (stop and start) the Apache service:
sudo systemctl restart apache2
sudo systemctl restart mysql
Step 6 – Test Setup
After completing all steps, Create a new file named
info.php inside your custom web root folder:
Add the following text into it:
Save and close the file.
Now, open your web browser and access your server’s domain name or IP address followed by the script name
info.php. You will see a page like below:
That’s it. You successfully install LAMP stack (Apache, MySQL, PHP) on your Ubuntu 20.04 LTS server.
