How to install and configure MariaDB 10.7 on Ubuntu 20.04

In this guide we are going to install MariaDB 10.7 development version, but first what is MariaDB?

MariaDB Server is one of the most popular open-source relational databases. It’s made by the original developers of MySQL and guaranteed to stay open source. It is part of most cloud offerings and the default in most Linux distributions.

It is built upon the values of performance, stability, and openness, and MariaDB Foundation ensures contributions will be accepted on technical merit. Recent new functionality includes advanced clustering with Galera Cluster 4, compatibility features with Oracle Database and Temporal Data Tables, allowing one to query the data as it stood at any point in the past.

You need to have Ubuntu 20.04 server with non-root administrative privileges and a firewall configured with UFW. Check out this for initial server setup guide for Ubuntu 20.04.

Installing MariaDB 10.7

1. Run system updates

Begin by updating your apt repository with the following command on your terminal

$ sudo apt update && apt upgrade -y

2. Install MariaDB dependencies

After updates are complete you can then install the MariaDB server by adding the apt repository to our system and also add GPG key.

Install dependencies

$ sudo apt install software-properties-common dirmngr apt-transport-https

Sample output.

Reading package lists... Done

dirmngr is already the newest version (2.2.19-3ubuntu2.1).
dirmngr set to manually installed.

software-properties-common set to manually installed.
apt-transport-https is already the newest version (2.0.6).

Add GPG keys

$ sudo apt-key adv --fetch-keys 'https://mariadb.org/mariadb_release_signing_key.asc'

Sample output will look like this;

$ Executing: /tmp/apt-key-gpghome.9NqByLiyl1/gpg.1.sh --fetch-keys https://mariadb.org/mariadb_release_signing_key.asc
gpg: requesting key from 'https://mariadb.org/mariadb_release_signing_key.asc'
gpg: key F1656F24C74CD1D8: "MariaDB Signing Key <[email protected]>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

Lastly, add the apt repository to our system.

$ sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el,s390x] https://mariadb.mirror.liquidtelecom.com/repo/10.7/ubuntu focal main'

NB: Change mirror location to reflect where you are downloading from

Run system updates again

$ sudo apt update

We can check to see if the repository has been added.

$ apt policy mariadb-server

Output

mariadb-server:
  Installed: (none)

3. Install Mariadb 10.7 on Ubuntu 20.04

3. Initial MariaDB configuration

The installation process will not ask you to set a password and this leaves MariaDB insecure. We will use a script that the MariaDB-server package provides strict access to the server and remove unused accounts. Read more about the security script here.

To ensure that our database is secure we need to run the mysql_secure_installation command to remove all remote root login, remove anonymous users, etc.

$ sudo mysql_secure_installation

The following sample output will be displayed.

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] n
 ... skipping.

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

Change the root password? [Y/n] n
 ... skipping.

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
 ... 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
 ... 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
 - 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
 ... 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!

Next is to enable MariaDB database

$ sudo systemctl enable mariadb

Start MariaDB database

$ sudo systemctl start mariadb

Check the status of the MariaDB database

$ sudo systemctl status mariadb

Test MariaDB 10.7

To test MariaDB we can create a database. Login to MariaDB console with the following command.

$ mysql -u root -p
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 51
Server version: 10.7.1-MariaDB-1:10.7.1+maria~focal mariadb.org binary distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Conclusion

We have learned how to install MariaDB on Ubuntu 21.04 server and secured it using the mysql_secure_installation script. You can now practice running SQL queries to learn more. I hope you enjoyed it and you have learned something new.
