Red Hat Enterprise Linux 7 (RHEL 7) and CentOS 7 were released back in 2014, and has support until 2024 when it reaches end-of-life. The CentOS Project follows releases of upstream RHEL source code with community binary builds a few months later. MariaDB Database Server can be installed on both RHEL 7 and CentOS 7 Linux servers. MariaDB is an open source and successful database project created from MySQL. It enjoys support from hundreds to thousands of open source contributors, and some companies.
In this guide, we shall be performing an installation of MariaDB 10.7 on CentOS 7 / RHEL 7 Linux system. Please note this is a single node database server setup using MariaDB. If you’re interested in a highly available deployment, consider using MariaDB Galera Cluster setup.
Some good features available in MariaDB 10.7 includes;
- New UUID Data Type – There is a new UUID data type aimed at the storage of 128-bit UUID (Universally Unique Identifier) data.
- Natural Sort – To be used in ordering of strings in alphabetical order
- Updates in InnoDB – New improvements and features in the MariaDB InnoDB storage engine
- Addition of Provider Plugins – There are five provider plugins (bzip2, lzma, lz4, lzo, snappy) for compression functionalities.
- New SFORMAT function
- InnoDB Bulk Insert – In bulk insert, pre-sort and build indexes one page at a time
- Password Reuse – The password_reuse_check plugin is a new password validation plugin
- Diagnostics Property – Used to identify the affected row
- Among many other new features, improvements and deprecations.
Install MariaDB 10.7 on CentOS 7 / RHEL 7
Follow the steps provided in the next sections to perform a working installation ofMariaDB 10.7 on CentOS 7 / RHEL 7 Linux machine. Ensure you’re not running any other MySQL based database management system, else uninstallation has to be performed prior to this setup.
Step 1) Add MariaDB YUM repository
A MariaDB YUM repository for RHEL based systems is available and can be added by running the following commands:
curl -LsS -O https://downloads.mariadb.com/MariaDB/mariadb_repo_setup
sudo bash mariadb_repo_setup --mariadb-server-version=10.7The script executed automates the configuration of MariaDB repositories for YUM and the importation of all required GPG keys.

mariadb Ver 15.1 Distrib 10.7.1-MariaDB, for Linux (x86_64) using readline 5.Run mariadb-secure-installation script which helps you secure your MariaDB database server
$ 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): <ENTER>
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
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
New password: <INPUT-PASSWORD>
Re-enter new password: <CONFIRM-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
... 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!Access to MariaDB shell should only be possible with a password
