How to Install MySQL on AlmaLinux 9

MySQL is a freely available open-source Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). SQL is the most popular language for adding, accessing, and managing content in a database. It is most noted for its quick processing, proven reliability, ease, and flexibility of use.

Start the MySQL service and enable it to automatically start on boot by running the following command.

systemctl enable --now mysqld
systemctl start mysqld

To check the MySQL service by running the following command.

systemctl status mysqld


[root@server ~]# systemctl status mysqld

Securing MySQL

Finally, you will want to secure your MySQL installation by issuing the following command.



[root@server ~]# mysql_secure_installation

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No:
Please set the password for root here.

New password:

Re-enter new password:
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y

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? (Press y|Y for Yes, any other key for No) : y

By default, MySQL 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

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...

 - Removing privileges on test database...
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

All done!

Once secured, you can connect to MySQL and review the existing databases on your database server by using the following command.

mysql -e "SHOW DATABASES;" -p


[root@server ~]# mysql -e "SHOW DATABASES;" -p
Enter password:
| Database           |
| information_schema |
| mysql              |
| performance_schema |
| sys                |
