Installing LAMP Stack on Debian 11 bullseye

Hello,

In this week’s feature highlight, we look at How to Install LAMP Stack on Debian 11 bullseye

A LAMP stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is actually an acronym which represents the Linux operating system, with the Apache web server. The site data is stored in a MariaDB database, and dynamic content is processed by PHP.

Update Debian 11 Bullseye

apt update && apt -y upgrade

Install MaridaDB database server

To get started with MariaDB installation, follow the below steps:

apt install -y mariadb-server mariadb-client

Check the status of mariaDB database server.

systemctl status mariadb

Output:

root@server:~# systemctl status mariadb
● mariadb.service - MariaDB 10.5.11 database server
Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2021-08-03 19:42:28 IST; 36min ago
Docs: man:mariadbd(8)

Run the command below to secure your database server,

mysql_secure_installation

Using the above command, you can do the following,

  • Set root password.
  • Remove anonymous users.
  • Disable remote login for root user.
  • Remove test database and access to it.

You can log in as your root user and set up a regular user and a database.

mysql -u root -p

Output:

root@server:~# mysql -u root -p
Enter password:

Restart service when a change is made & enable the service to start at boot.

systemctl enable apache2

Open server IP address on your browser(http://IPADDRESS) to see default Apache page.

Example

Install PHP

Follow the below steps to install PHP on the server,

apt install php libapache2-mod-php php-cli php-fpm php-json php-pdo php-mysql php-zip php-gd  php-mbstring php-curl php-xml php-pear php-bcmath

Output:

root@server:~# apt install php libapache2-mod-php php-cli php-fpm php-json php-pdo php-mysql php-zip php-   gd  php-mbstring php-curl php-xml php-pear           php-cmath
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'php7.4-common' instead of 'php-pdo'
The following additional packages will be installed:libapache2-mod-php7.4 php-common php7.4 php7.4-bcmath php7.4-cli php7.4-curl php7.4-fpm php7.4-gd             7.4-json php7.4-mbstring php7.4-mysql php7.4-opcache php7.4-readline php7.4-xml php7.4-zip

Enable Apache module if not already enabled then restart the Web Server.

a2enmod php7.4

Confirm the PHP version

php -v

Output:

root@server:~# php -v
PHP 7.4.21 (cli) (built: Jul  2 2021 03:59:48) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
with Zend OPcache v7.4.21, Copyright (c), by Zend Technologies

In order to test the PHP is working on the server, we will create a small file that will list out all the PHP information available.

Run the below command which will create a file,

echo "<?php phpinfo(); ?>" > /var/www/html/info.php

To view the PHP info on your browser, http://IP_address/phpinfo.php

Example.

PHP info

Once you confirmed that the PHP has been installed and working, remove the info.php for security reasons.

rm /var/www/html/info.php
