How to Install MariaDB on Manjaro 21 Linux

MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL would suddenly become a paid service due to Oracle acquiring it in 2010. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

MariaDB has become just as popular as MySQL with developers, with advanced clustering with Galera Cluster 4, faster cache/indexes, storage engines, and features/extensions that you won’t find in MySQL.

In the following tutorial, you will learn how to install MariaDB on Manjaro 21 Linux. The tutorial will install the database software using the Pacman package manager using the command line and some essential tips on securing MariaDB.

Update Manjaro

Before proceeding with the tutorial, it is good to ensure your system is up-to-date with all existing packages.

sudo pacman -Syu

Install MariaDB

The first step is to install MariaDB; Manjaro always features the latest up-to-date version as the same with Arch Linux, use the following command as follows.

sudo pacman -Sy mariadb

Once the installation has been completed, you will need to initialize the database using the following command.

sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

Example output:

Next, enable MariaDB on system boot and start the service immediately in your current session.

sudo systemctl enable mariadb --now

Optionally, once you have initialized MariaDB, check the installation of MariaDB by checking the version and build using the following command.

mariadb --version

Example output:

Enable MariaDB Service

Now you have installed MariaDB, and you can verify the status of the database software by using the following systemctl command:

systemctl status mariadb

Example:

How to Install MariaDB on Manjaro 21 Linux

By default, you will find MariaDB status to be activated. If not, start MariaDB, use the following command:

sudo systemctl start mariadb

To stop MariaDB:

sudo systemctl stop mariadb

To enable MariaDB on system startup:

sudo systemctl enable mariadb

To disable MariaDB on system startup:

sudo systemctl disable mariadb

To restart the MariaDB service:

sudo systemctl restart mariadb

Run MariaDB Security Script

When installing MariaDB fresh, default settings are considered weak by most standards and cause concern for potentially allowing intrusion or exploiting hackers. A solution is to run the installation security script with the MariaDB installation.

First, use the following command to launch the (mysql_secure_installation):

sudo mariadb-secure-installation

Next, follow below:

  • Setting the password for root accounts.
  • Removing root accounts that are accessible from outside the local host.
  • Removing anonymous-user accounts.
  • Removing the test database, which by default can be accessed by anonymous users.

Note you use (Y) to remove everything.

Example:

[joshua@manjaro-linx-21 ~]$ sudo mariadb-secure-installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] Y <---- Type Y then press the ENTER KEY.
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] Y <---- Type Y then press the ENTER KEY.
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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? [Y/n] Y <---- Type Y then press the ENTER KEY.
 ... 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? [Y/n] Y <---- Type Y then press the ENTER KEY.
 ... Success!

By default, MariaDB 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? [Y/n] Y <---- Type Y then press the ENTER KEY.
 - 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? [Y/n] Y <---- Type Y then press the ENTER KEY.
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Run MariaDB Database Tables Upgrade Tool

For users who have upgraded from a previous version of MariaDB, you should use the following steps and run the tool designed to check your tables and fix any issues with the version upgrade.

Run the following command to begin the upgrade, or check that your database tables are ok.

sudo mariadb-upgrade

Example output (the database was already updated):

How to Install MariaDB on Manjaro 21 Linux

Alternatively, if you want to re-run the command to ensure everything is correct, use the following command with –force.

sudo mariadb-upgrade --force

Remove (Uninstall) MariaDB

If you no longer wish to use MariaDB and want to remove it in full, execute the following command:

sudo pacman -R mariadb

Note that this command will remove most of the unused dependencies in the MariaDB installation to help clean up your system.

Comments and Conclusion

In the tutorial, you have learned how to install the latest version of the MariaDB Community release on Manjaro 21 Linux.

Overall, MariaDB is releasing new branches at a rapid pace these days; news of MariaDB 10.9 is already circulating, and as of the time of this lesson, 10.7 has just been published and 10.8 in RC status at the time of the creation of this tutorial, in a few months these versions will be much further along.

Most notable about MariaDB is how reliable the latest releases are; for developers, MariaDB is worth investigating to begin working in, and for CMS users and similar, upgrade with caution.
