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 10.6 on CentOS 8 Stream.
Table of Contents
- Recommended OS: Any current CentOS 8 Stream.
- User account: root access
Updating Operating System
Update your CentOS Stream operating system to make sure all existing packages are up to date:
sudo dnf upgrade --refresh -y
The tutorial will be using the sudo command and assuming you have sudo status.
To verify sudo status on your account:
Example output showing sudo status:
[joshua@centos-stream ~]$ sudo whoami root
To set up an existing or new sudo account, visit our tutorial on adding a User to Sudoers on CentOS Stream.
To use the root account, use the following command with the root password to log in.
Import MariaDB 10.6 Repository
The second choice and maybe more preferred is to use the official bash script as any updates will be instant once deployed to the official repositories. Users not near their servers may face some issues, but this will not be an issue for the majority.
In your terminal, use the following command.
curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=10.6 --skip-maxscale --skip-tools
If the command fails, you most likely forgot to install the curl package.
sudo dnf install curl -y
Note, the maxscale and tools were skipped. You can remove these flags, but at the current moment, tools are not supported for RHEL type distributions. Most users will not need these extras.
This shows the repository has been successfully imported.
Install MariaDB 10.6 on CentOS
To install MariaDB, you will need to install the client and the server packages. This can be done as follows:
sudo dnf install mariadb-server
Type Y and then press the ENTER KEY to proceed with the installation.
Confirm the installation of MariaDB by checking the version and build:
mariadb Ver 15.1 Distrib 10.6.5-MariaDB, for Linux (x86_64) using readline 5.1
Check MariaDB 10.6 Service Status
By default, MariaDB is installed and not activated to enable MariaDB to use the following command.
sudo systemctl enable mariadb --now
Now you have installed MariaDB, and you can verify the status of the database software by using the following systemctl command:
systemctl status mariadb
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
Secure MariaDB 10.6 with 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):
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.
[joshua@centos-stream-8 ~]$ 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!
Login to MariaDB 10.6 Terminal Instance
Now that you have completed the post-installation installation security script, login into your MariaDB database can be done using the following:
sudo mysql -u root -p
You will be prompted to enter the root password that you set in either the installation setup or post-installation security script. Once inside the MariaDB service instance, you can execute the following command as a test to see it in operation.
Type the following SHOW DATABASE command:
For those new to MySQL/MariaDB, all commands syntax must end with “;”
TO (CREATE) a database, use the following command.
CREATE DATABASE MYDATA;
To delete (DROP) a database, use the following command.
DROP DATABASE MYDATA;
To exit the terminal, type the following exit command :
How to Remove (Uninstall) MariaDB 10.6
If you no longer wish to use MariaDB and want to remove it in full, execute the following command:
sudo dnf remove mariadb*
Type Y and then press the ENTER KEY to proceed with the uninstallation.
Note that this command will remove most of the unused dependencies in the MariaDB installation to help clean up your system.
To remove the bash script repository, use the following command.
sudo rm /etc/yum.repos.d/mariadb.repo
Comments and Conclusion
In the tutorial, you have learned how to install the latest MariaDB 10.6 Community release CentOS 8 Stream.
Overall, it is pretty safe for most users who do not operate in strict production environments to upgrade from the old stable MariaDB 10.5 to the current stable branch 10.6. There are considerable advantages in performance with upgrading. If you do upgrade, always back up your database before doing so to avoid countless hours of pain and utter frustration in anything to do with database maintenance or upgrades.
