Hello, friends. It is not yet known for sure which is the most used database driver, but MariaDB has to be in the first place. So, in this post, you will learn how to install MariaDB on Debian 11. This step is essential if you want to have applications running on your system.
MariaDB is a well-known archi Database Relationships Management System that is a MySQL fork. This is due to the purchase of Sun Mycrosystem by Oracle. It is perfectly compatible with MySQL and is available in most Linux distributions.
Therefore, it is quite popular and many developers use it for their applications or even to manage the most sensitive data you can imagine.
So, let’s go for it.
As it usually happens, MariaDB is available from the official Debian 11 repositories. If you want to check it out, then, just run the following command
apt search mariadb
There you will see many packages related to MariaDB such as the server and the client.
So, to install the server that concerns us today, then you can run the following command
apt install mariadb-server Reading package lists... Done Building dependency tree... Done Reading state information... Done The following additional packages will be installed: galera-4 gawk libconfig-inifiles-perl libdbi-perl libmariadb3 libmpfr6 libsigsegv2 libsnappy1v5 mariadb-client-10.5 mariadb-client-core-10.5 mariadb-common mariadb-server-10.5 mariadb-server-core-10.5 mysql-common socat Suggested packages: gawk-doc libclone-perl libmldbm-perl libnet-daemon-perl libsql-statement-perl mailx mariadb-test netcat-openbsd Recommended packages: libdbd-mariadb-perl | libdbd-mysql-perl libterm-readkey-perl libhtml-template-perl The following NEW packages will be installed: galera-4 gawk libconfig-inifiles-perl libdbi-perl libmariadb3 libmpfr6 libsigsegv2 libsnappy1v5 mariadb-client-10.5 mariadb-client-core-10.5 mariadb-common mariadb-server mariadb-server-10.5 mariadb-server-core-10.5 mysql-common socat 0 upgraded, 16 newly installed, 0 to remove and 0 not upgraded. Need to get 18.0 MB of archives. After this operation, 157 MB of additional disk space will be used. Do you want to continue? [Y/n]
There is a package that refers to the MariaDB client which is
mariadb-client that you can install at your convenience.
To check the version of MariaDB installed, you can run the following command
mariadb --version mariadb Ver 15.1 Distrib 10.5.11-MariaDB, for debian-linux-gnu (x86_64) using EditLine wrapper
As with other system services, when MariaDB is installed, it will be started and enabled so that it can start with the system.
You can stop the service by running
systemctl stop mariadb
If you want to start it again, then run
systemctl start mariadb
Finally, you can check the status of the service by running this command

When MariaDB is installed, it does not include a password for the root user, so it is immediately necessary to set one. For this, we have the
mysql_secure_installation script to help us with this.
When prompted for the root user password, just press ENTER:
Enter current password for root (enter for none):
Now you can define the MariaDB authentication protocol.
If You already have your root account protected, so you can safely answer 'n'. Switch to unix_socket authentication [Y/n]
And now yes, you can change the root password by answering Y to the question
Change the root password? [Y/n] New password: Re-enter new password: Password updated successfully! Reloading privilege tables... ... Success!
Then, there follows a series of questions that have to do with MariaDB configuration and security. You can answer each one AND
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
And then the script will finish executing.
With this, MariaDB will be ready for you to use and access the shell.
mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 54 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)]>
So, enjoy it
MariaDB is a database driver widely used by many programming enthusiasts. Learning how to install it can pave the way to getting the most out of it in this area.
