MariaDB Server

Updated April 11, 2023

Definition of MariaDB Server

MariaDB server is the one of most famous relational database management and the MariaDB server is officially supported by MySQL relational database management system. On the other hand, we can also call it a child of MySQL in the updated version. Basically, MariaDB operates on the cloud and supports Linux administration. MariaDB normally works on stability, reliability, and openness as well as the performance of the databases. The Latest version of It provides clustering functionality to the user. It supports all repositories of Linux operating systems. MariaDB is compatible with the oracle database management system. Finally, we can say that the MariaDB server works like a relational database and it provides an SQL interface to access data.

How to use MariaDB server?

Let’s see how we use MariaDB server, basically, MariaDB is replayed by MySQL and it is the default database system to CentOS. First, see how we can install the MariaDB server as follows.

We will see how we can install the MariaDB server on CentOS operating system by using the following command.

sudo yum install mariadb-server

Explanation:

In the above command, we use the yum package manager to complete the installation of the MariaDB server.

After that, we need to allow remote access by using the following command as follows.

firewall-cmd --zone=public --add-service=mysql --permanent

The next step is to set the root password. The main reason to set a root password is that we just complete the installation of the MariaDB server, so we need to set a root password for security purposes by using the following command.

/usr/bin/mysql_secure_installation

After installation of the server, we need to restart some database services by using the following command as follows.

We can restart the server by the following commands as follows.

sudo systemctl start mariadb.service

We can stop the server by the following commands as follows.

sudo systemctl stop mariadb.service

In the next step, we need to reboot the server by using the following command.

sudo systemctl enable mariadb.service

The final step is to start the server shell and run the following command.

mysql –u root –p

After running the above command, insert the root password that we already set at the time of installation. Then the shell command prompt is open as the following snapshot as follows.

Now let’s see how we can use the server as follows.

Suppose database administrators want to see details of all users by using the following statement as follows.

select Password, Host, User from mysql.user;

Explanation:

In the above statement, we use a select clause to access data from MySQL, after that we write different attribute names that we need to show such as Password, Host, and user as shown in the above statement. After that we mysql.user means here MySQL is a database name and the user is the table name and a semicolon is used to end the statement.

It works like MySQL, which means it uses the same command as follows.

Suppose the user needs to create a database. At that time users can use the following command to create a database as follows.

create database database_name;

Suppose users need to see all available databases on the server then we can use the following command as follows.

show databases;

So in this way, we can use the MariaDB server as well as we can set privileges or we can manage users by using different commands like MySQL.

MariaDB Server Uses

The MariaDB server uses client-server architecture with a server program that requests files from the client program; we can say that a typical client-server machine and client program will be different hosts.

• It is used to manage data processing capabilities.
• It is used for reliability to the user.
• It is used to create databases, to drop the database as well as to create users and drop users by using commands.
• It provides a data analysis service.

Features

• MariaDB is equivalent to MySQL, every version of MariaDB works as a drop-in replacement of the MySQL version.
• When we migrate to MariaDB its binary data files are compatible with the MySQL version as well as client protocol is also compatible with MySQL.
• Its supports different SQL structures, procedures, functions, statements, user-defined functions, server variables, partitioning of tables, and backup.
• MariaDB supports different new features such as extensions, storage engines, and bug fixes. It also provides some advanced features such as clustering with Galera Cluster 4 and many more features are compatible with oracle database systems.
• The most important feature of the server is that it provides security options to the user.
• Basically, it works under LGPL, BSD, and GPL licenses.
• It supports query language.
• MariaDB supports the PHP programming language or we can say that web development.
• The Main advantage of MariaDB is it supports different programming languages as well as runs on different operating systems.
• MariaDB supports some additional features that are not present in MySQL which have a negative impact on database management systems.
• MariaDB has some powerful features such as usability and security.
• Another powerful feature of MariaDB is its improvement of server performance as well as a system that cannot be found in MySQL.
• It supports metadata for replication as well as binary logs.
• It provides a very good platform for small-scale and global scale development.
• It provides high availability such as automatic failover.
• It is many more functions as well as many commands that are not present in the MySQL server.

Conclusion

We hope from this article you have understood about the MariaDB Server. From the above article, we have learned different uses of MariaDB Server as well as how we can use them. We also learned the key feature of the MariaDB server with different parameters that are not present in MySQL. From this article, we learned how and when we use MariaDB Server.
