Step 2: Install Mariadb

you can install mariadb from debian base repository.

sudo apt install mariadb-server

After MariaDB is installed, start the MariaDB service and enable it to start at system boot and check the status with below commands.

sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo systemctl status mariadb

sample output:

● mariadb.service - MariaDB 10.5.11 database server
     Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2021-09-01 05:16:49 PDT; 22min ago
       Docs: man:mariadbd(8)
             https://mariadb.com/kb/en/library/systemd/
    Process: 3873 ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld (code=exited, status=0/SUCCESS)

you can check the version using below command.

sudo mariadb --version

Then run the mysql_secure_installation script to secure the MariaDB.

sudo mysql_secure_installation

then it prompts to set mariadb Mariadb root password, remove anonymous users, remove test db etc.

Switch to unix_socket authentication [Y/n] y
Change the root password? [Y/n] y
New password:
Re-enter new password:
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

Now you need to provide username and password to access MySQL console.

sudo mysql -u root -p

it promts to mariadb root password. once you login to mariadb shell, you can check version using SELECT VERSION() command as below.

root@debian:~# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 52
Server version: 10.5.11-MariaDB-1 Debian 11
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> SELECT VERSION();

| VERSION()         |
+-------------------+
| 10.5.11-MariaDB-1 |
+-------------------+
1 row in set (0.001 sec)
MariaDB [(none)]>

then type exit to close the shell.

Step 3: Install php

By default, the version of PHP available in the Debian 11 is PHP 7.4.we need to install Php and Php extension package for MariaDB to connect with the db.

sudo apt install php php-cli php-mysql libapache2-mod-php php-gd php-xml php-curl php-common 

you can check the php version as below.

php -v

output:

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

Then you must restart apache service using the following command.

sudo systemctl restart apache2

Step 4: Test php on Apache

Now you can create sample php file as info.php in the default document root of apache server as below.

nano /var/www/html/info.php

Add below lines to above file.
