What is MariaDB?:
MariaDB is a community-developed, commercially supported fork of the MySQL relational database management system (RDBMS), intended to remain free and open-source software under the GNU General Public License. Development is led by some of the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle Corporation in 2009.
MariaDB is intended to maintain high compatibility with MySQL, with library binary parity and exact matching with MySQL APIs and commands, allowing it in many cases to function as drop-in replacement for MySQL. However, new features are diverging. It includes new storage engines like Aria, ColumnStore, and MyRocks.
Its lead developer/CTO is Michael “Monty” Widenius, one of the founders of MySQL AB and the founder of Monty Program AB. On 16 January 2008, MySQL AB announced that it had agreed to be acquired by Sun Microsystems for approximately $1 billion. The acquisition completed on 26 February 2008. Sun was then bought the following year by Oracle Corporation. MariaDB is named after Widenius’ younger daughter, Maria. (MySQL is named after his other daughter, My. (Source: Wikipedia)
MariaDB vs MySQL
MariaDB and MySQL are both popular open-source relational database management systems (RDBMS) with similar roots, but they have diverged over time. Here’s a comparison to help you understand their differences and decide which one might be better suited for your needs:
Origins and Development
- MySQL: Originally developed by MySQL AB, it was acquired by Sun Microsystems and later by Oracle Corporation. Oracle now maintains MySQL.
- MariaDB: Created by the original developers of MySQL after concerns about Oracle’s acquisition. It aims to maintain open-source freedom and compatibility with MySQL.
Licensing
- MySQL: Dual-licensed under the GPL and a commercial license. Some advanced features are available only under the commercial license.
- MariaDB: Entirely open-source under the GPL. All features are available without the need for a commercial license.
Features
- MySQL:
- Strong community and widespread adoption.
- Some enterprise features (e.g., MySQL Enterprise Firewall) are only available in the commercial version.
- Offers different storage engines, with InnoDB as the default.
- MariaDB:
- Includes features not found in MySQL, such as the Aria storage engine and advanced Galera Cluster for synchronous multi-master replication.
- Generally, incorporates community-contributed patches faster.
- Strives for backward compatibility with MySQL, including matching command-line options and API endpoints.
Performance
- MySQL: Known for stability and reliability. Performance can be enhanced with proprietary add-ons available through Oracle.
- MariaDB: Often includes performance improvements and optimizations. Some benchmarks show MariaDB performing better in certain scenarios due to additional storage engines and query optimizations.
Compatibility
- MySQL: Standard in many applications and services; widely supported by third-party tools and hosting providers.
- MariaDB: Designed to be a drop-in replacement for MySQL. Most MySQL connectors, clients, and libraries work seamlessly with MariaDB. Some newer MySQL features may not be immediately available in MariaDB.
Community and Support
- MySQL: Backed by Oracle, offering extensive professional support and resources. A large community of users and developers provides a wealth of information and third-party tools.
- MariaDB: Maintained by the MariaDB Foundation, which ensures its open-source nature. It has a growing community and increasing enterprise adoption, with various support options available through MariaDB Corporation.
Use Cases
- MySQL: Suitable for applications that rely on Oracle’s proprietary features or those embedded in Oracle’s ecosystem. It remains a popular choice for web applications, enterprise environments, and software that explicitly supports MySQL.
- MariaDB: Ideal for users who prioritize open-source software, need features like Galera Cluster for high availability, or want to avoid potential licensing costs associated with MySQL’s commercial version. It’s increasingly being adopted for enterprise applications and large-scale deployments.
Conclusion
- Choose MySQL if you need guaranteed compatibility with Oracle’s ecosystem, rely on enterprise features provided by Oracle, or require a widely supported and stable RDBMS.
- Choose MariaDB if you prefer a fully open-source solution with advanced features, improved performance, and a commitment to open-source principles. It’s also a strong choice if you want to avoid potential licensing costs and embrace a rapidly evolving platform.

Configure initial settings of your MariaDB database server as follows.
# 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] n
... skipping.
You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] Y
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
... 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!Login to your database server by using mysql command and execute some SQL commands thereon.
# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or g. Your MariaDB connection id is 11 Server version: 10.9.3-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or 'h' for help.

If you planning to access your database server over the network then you need to allow the service/port in Linux firewall, otherwise you can skip this step.
# firewall-cmd --permanent --add-service=mysql success # firewall-cmd --reload success
You have successfully setup MariaDB server on Linux.
Install phpMyAdmin on Rocky Linux 9
phpMyAdmin is the most popular and de facto preferred tool for MySQL database administration. Just like MariaDB, it is also free and open source. As a portable web application written primarily in PHP, it has become one of the most popular MySQL administration tools, especially for web hosting services.
phpMyAdmin is a PHP web application, therefore, you need a LAMP or LEMP server to deploy it.
Here, we are using Apache based PHP server (i.e. LAMP), however you can also install a Nginx based PHP server (i.e. LEMP) according to your requirements.
Execute following dnf command to install Apache, PHP, PHP modules and other required software packages in one go.
# dnf install -y httpd php php-common php-opcache php-cli php-gd php-curl php-mysqlnd php-xml wget policycoreutils-python-utils
Enable and start Apache and PHP services.
# systemctl enable --now httpd.service php-fpm.service Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service. Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.
Allow the http service in Linux Firewall.
# firewall-cmd --permanent --add-service=http success # firewall-cmd --reload success
phpMyAdmin is a free software, therefore you can download it from their official website.
Or you can copy the link and use it with wget command to download phpMyAdmin straight from Linux commandline. Just as we did below.
# cd /tmp # wget https://files.phpmyadmin.net/phpMyAdmin/5.2.0/phpMyAdmin-5.2.0-english.tar.gz --2022-09-29 15:40:01-- https://files.phpmyadmin.net/phpMyAdmin/5.2.0/phpMyAdmin-5.2.0-english.tar.gz Resolving files.phpmyadmin.net (files.phpmyadmin.net)... 212.102.56.179, 195.181.170.18, 156.146.33.27, ...

Extract the downloaded file in Apache document root by using tar command.
# tar xf phpMyAdmin-5.2.0-english.tar.gz --directory /var/www/html
Rename the phpMyAdmin software directory for easy accessibility.
# mv /var/www/html/phpMyAdmin-5.2.0-english/ /var/www/html/pma
phpMyAdmin software provides a SQL script to create its meta data repository. You can easily execute it by using mysql command as follows.
# mysql -u root -p < /var/www/html/pma/sql/create_tables.sql Enter password:
Create a copy of phpMyAdmin configuration file in the application root.
# cp /var/www/html/pma/config.sample.inc.php /var/www/html/pma/config.inc.php
Open config.inc.php file in vim text editor.
# vi /var/www/html/pma/config.inc.php
Locate and set following directives in this file.
$cfg['blowfish_secret'] = 'I;Am;Fan;0f;0p3n;S0urc3;S0ftwar3'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */ $cfg['Servers'][$i]['host'] = '127.0.0.1';
Create a temporary directory to cache templates by the web application.
# mkdir /var/www/html/pma/tmp
Set apache user as the owner of pma directory.
# chown -R apache:apache /var/www/html/pma/
Enable following SELinux Boolean to allow Apache to connect with your MariaDB Database.
# setsebool -P httpd_can_network_connect 1
Set SELinux permissions for tmp directory, to make it writable by the apache user.
# semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/pma/tmp(/.*)?" # restorecon -Rv /var/www/html/pma/tmp Relabeled /var/www/html/pma/tmp from unconfined_u:object_r:httpd_sys_content_t:s0 to unconfined_u:object_r:httpd_sys_rw_content_t:s0
Create a Admin user in MariaDB database. You can use this user to login via phpMyAdmin administration panel.
# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or g. Your MariaDB connection id is 14 Server version: 10.9.3-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. MariaDB [(none)]> CREATE USER ahmer@localhost IDENTIFIED BY 'pma'; Query OK, 0 rows affected (0.025 sec) MariaDB [(none)]> GRANT ALL ON *.* TO ahmer@localhost; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> exit Bye
Open URL http://mariadb-01.centlinux.com/pma/ in a web browser.
Login as user ‘ahmer’.
You are now at the dashboard of phpMyAdmin administration panel. To effectively user your MySQL administration tool, you should read Mastering phpMyAdmin 3.4 for Effective MySQL Management (PAID LINK) by Packt Publishing.
