Step #3 : Find MySQL Root Password

If you install MySQL 8.0 it will create a temporary password for MySQL root user. You can find this password using its log file as shown below.

# grep "A temporary password" /var/log/mysqld.log

[Note] A temporary password is generated for root@localhost: hosygMikj1+t636

Step #4 : Start MySQL Service

After installing MySQL server now lets start MySQL service using below command.

Using SysVinit

# service mysqld start

Using Systemd

# systemctl start mysqld.service

Step #5 : MySQL Secure Installation

# mysql_secure_installation

You will get some output like below:

New password:

Re-enter new password:
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.

Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : No

 ... skipping.
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
environment.

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

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
environment.


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

Success.

All done!

Step #6 : Restart and Eanble MySQL Service at Boot Time

# service mysqld restart

### Using Systemd
