How to Install MariaDB 5.5 Server on RHEL 7/CentOS 7 Linux with Easy Steps

In this article, I will take you through 6 Simple and Easy Steps to Install MariaDB Server on Linux(RHEL/CentOS 7/8). MariaDB is an open source MySQL based relational database management system. It is probably the most popular database currently in use on Linux Based Platforms due to its various features over other databases. It offers better storage engine along with faster caching and query performance. For more info, check MariaDB Official Website. We will look into the detailed steps required to Install MariaDB 5.5 Server on RHEL 7/CentOS 7 Servers.

Step 1: Prerequisites

a) You need to have a running RHEL 7/CentOS 7 System.

b) You should have yum tool installed in your Server. You can check Top 22 YUM command examples in RedHat/CentOS 7 to know more about yum command.

c) You need to have root or sudo access to run privileged commands. Please Check How to Add User to Sudoers to know more about providing sudo access to the User.

Step 2: Update Your Server

Before going through the steps to install MariaDB 5.5 Server on RHEL 7/CentOS 7, it is always recommended to update your Server first by using yum update -y command as shown below.

Complete!

Step 4: Enable and Start MariaDB Server

After installing MariaDB if you check the status using systemctl status mariadb command then you can see by default it does not start the service after installation. So you need to start it manually and then enable it.

[root@localhost ~]# systemctl status mariadb
● mariadb.service - MariaDB database server
Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled)
Active: inactive (dead)

You can start the mariadb service by using systemctl start mariadb command as shown below. If there is any error in starting the MariaDB service then it will show on the output.

[root@localhost ~]# systemctl start mariadb

Then enable the service by using systemctl enable mariadb command as shown below.

[root@localhost ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

Once started you can check and verify the service status using systemctl status mariadb command as shown below.

[root@localhost ~]# systemctl status mariadb
● mariadb.service - MariaDB database server
Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)

Step 5: Secure Your MariaDB Server

After every installation, it is always recommended to first secure your MySQL Server by using mysql_secure_installation tool as shown below. By using this tool, you can setup the root password, allow/remove the anonymous user access, allow/disallow the root login remotely, keep/delete the test database.

[root@localhost ~]# mysql_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
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set 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] n
... skipping.

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!

Step 6: Login to MariaDB Server

Once MySQL setup is ready, you can try to login using mysql -u root -p command as shown below. Here I am using root(-u) user to login to database as you can see in the below output. You can enable and use any user with sufficient privileges to login to database. If you are not providing any hostname(-h) then by default it will take localhost as your hostname. If you don’t want to provide password with -p option then you can simply use -p option without any argument, It will prompt you to provide the password.

[root@localhost bkp_mysql]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
