Before getting started, make sure to follow our Initial Server Setup Guide for CentOS 8 guide:

Also, make sure that you have wget installed:

  • sudo yum install wget

Adding the MariaDB repository

In order to install the latest stable MariaDB Community server on RHEL 8 or CentOS 8, you need to first add the MariaDB repository to yum.

To do so, you can use the following automation script provided by MariaDB:

  • Download the script:
  • wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup
  • Make the script executable:
  • chmod +x mariadb_repo_setup
  • Finally run the script:
  • sudo ./mariadb_repo_setup

With that, you are ready to install the latest stable MariaDB Community Server on your CentOS 8 server!

Installing the latest MariaDB version

With the MariaDB repository that we just added, dnf will install the stable MariaDB version.

To avoid any unexpected problems, first install the required dependencies:

  • sudo yum install perl-DBI libaio libsepol lsof boost-program-options

After that install MariaDB from the new repository that we just added by specifying it with the --repo argument:

  • sudo yum install --repo="mariadb-main" MariaDB-server

After that make sure to start MariaDB:

  • sudo systemctl start mariadb

And also make sure that the service is enabled so that it starts automatically in case of a server reboot:

  • sudo systemctl enable mariadb

Finally, check if MariaDB is running:

  • sudo systemctl status mariadb

With that you would have the latest MariaDB up and running!

Next make sure that you secure MariaDB as well!

Securing MariaDB

In order to secure your MariaDB server, you just need to run the following command:

  • sudo mysql_secure_installation

Finally to check your version run the following command:

  • mysqladmin -u root -p version
