To enable the MariaDB MySQL Server service on startup refer to the below command.
[root@localhost ~]# systemctl enable mariadb # Enable the MariaDB Service on Startup Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
To confirm the installed package of MariaDB Server and MariaDB client use the below command.
[root@localhost ~]# rpm -qa | grep mariadb # Confirm the installed Package mariadb-5.5.52-1.el7.x86_64 mariadb-server-5.5.52-1.el7.x86_64 mariadb-libs-5.5.52-1.el7.x86_64
To check the version of the MariaDB installed the package we can use the below command.
[root@localhost ~]# mysql --version; # Check Version of MariaDB Database Server Package Version mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1
Now to configure the MariaDB MySQL Server like, set a root password for MySQL server, remove anonymous users, Disallow root login remotely…etc, we can use the mysql_secure_installation command.
[root@localhost ~]# mysql_secure_installation # Configuring MariaDB Mysql Server
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): ---> Just Press ENTER to continue as currently we don't have any root password
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 # Enter "y" to Set root Password
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 ---> Enter "y" If you want to remove Anonymous Users to login MariaDB MySQL Server
... 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 ---> Enter "y" to Disable root Login of MariaDB Database Server on Remote Access
... 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 ---> Enter "y" to remove all test Database's and access to it from MariaDB MySQL Server
- 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 ---> Enter "y" reload Privilege Table
... 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!
