How to Install or Upgrade MariaDB 10.8 on Ubuntu 20.04 LTS

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 features such as 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 or upgrade MariaDB 10.8 on Ubuntu 20.04 LTS.

Update Ubuntu System

Update your Ubuntu operating system to make sure all existing packages are up to date:

sudo apt update && sudo apt upgrade -y

Install Depedencies

The first step is to install the dependencies needed for the installation.

To do this, use the following command in your terminal:

sudo apt-get install curl software-properties-common dirmngr ca-certificates apt-transport-https -y

Import MariaDB 10.8 GPG Key & Repository

By default, MariaDB is not available on Ubuntu 20.04 LTS but can be imported using the MariaDB bash script designed for Linux distributions such as Ubuntu that are supported given they are long-term releases.

In your terminal, use the following command.

curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=10.8

Note, if the command fails, most likely, you forgot to install the curl package.

sudo apt install curl -y

Example output:

Run MariaDB 10.8 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 that comes with the MariaDB installation.

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

sudo mysql_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@ubuntu-20-04 ~]$ 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 that 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 up 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:

Install/Upgrade MariaDB 10.8 on Ubuntu 20.04 LTS

Remove (Uninstall) MariaDB 10.8

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

sudo apt autoremove mariadb-server mariadb-client --purge -y

Note, this will remove MariaDB completely including all database data.

To remove the bash script repository, use the following command.

sudo rm /etc/apt/sources.list.d/mariadb.list
sudo apt update

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