How to Install MariaDB on Arch Linux / Manjaro Linux

MariaDB is a very popular open-source database management system everyone uses, from small to large enterprises. It is a fork of MySQL from MariaDB Corporation Ab, led by the original developers of MySQL.

MariaDB is fully compatible with the MySQL database and is widely used as a database server in the LAMP and LEMP stack.

In this post, we will see how to install MariaDB on Arch Linux / Manjaro Linux.

Install MariaDB on Arch Linux / Manjaro Linux

MariaDB foundation distributes packages via dedicated repositories for most Linux operating systems. Since Arch Linux follows a rolling release model, you can get the latest version of MariaDB from Arch Linux mirrors.

Update Arch Linux

First, update all the packages to bring your system to the latest release.

pacman -Syu

Then, reboot the system.


Install MariaDB

Now, install the MariaDB package from the nearest mirror.

pacman -Sy mariadb

Before starting the MariaDB service, initialize the database with the below command. You may also change the data directory of your choice, provided you set datadir=YOUR_DATADIR under the section [mysqld] of /etc/my.cnf.d/server.cnf.

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

Finally, start and enable the MariaDB service with the following command.

systemctl enable --now mariadb

Once the service is up, verify the status of the MariaDB service.

systemctl status mariadb

Secure MariaDB Installation

After installing MariaDB, you will need to run the mysql_secure_installation command to remove anonymous users, test databases, and disallow remote root login.


Official MariaDB Mirror


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):  << Just press enter
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] N  << Disable Unix Socket Authentication
 ... skipping.

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

Change the root password? [Y/n] Y  << Change Root Password
New password:  << Enter Password
Re-enter new password:  << Re-Enter 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  << Remove Anonymous Users
 ... 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  << Disallow root login remotely
 ... 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  << Remove test database
 - 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  << Reload Tables
 ... 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!

Access MariaDB

You can now log in to the MariaDB database with the MySQL root password.

mysql -u root -p
