For CentOS, RedHat, and Fedora, it is highly recommended to install from a repository using yum. This page walks you through the simple steps.

Adding the MariaDB YUM Repository

We have YUM repositories for several YUM-based Linux distributions. To easily generate the appropriate MariaDB.repo entry for your distribution, use our online repository generator.
We currently have YUM repositories for CentOS 5, CentOS 6, RHEL 5, RHEL 6, Fedora 16, and Fedora 17.
Once you have your MariaDB.repo entry, add it to a file under /etc/yum.repos.d/. (We suggest something like /etc/yum.repos.d/MariaDB.repo.)
An example MariaDB.repo file for CentOS 6 64 bits is:



The example file above includes a gpgkey line to automatically fetch the GPG key we use to sign the repositories. This key enables yum and rpm to verify the integrity of the packages it downloads.
The id of our signing key is 0xcbcb082a1bb943db. The short form of the id is 0x1BB943DB and the full key fingerprint is:



If you wish to fix the version to an older version, or do a yum downgrade, you can create a yum repo defination with a baseurl set to a specific version:



Installing MariaDB with YUM

With the repo file in place you can now install MariaDB like so:



If you don't have the MariaDB GPG Signing key installed, YUM will prompt you to install it after downloading the packages (but before installing them).

If the server already has the MariaDB-Galera-server package installed, you might need to remove it prior to installing MariaDB-server (with 'sudo yum remove MariaDB-Galera-server'). No databases are removed when the MariaDB-Galera-server rpm package is removed, but as with any upgrade, it is best to have backups.

After Installation

After the installation completes, start MariaDB with:


Manually Importing the MariaDB Signing Key

If you like, you can manually install the GPG key using the rpm application like so:
