    Step 3 – Secure MySQL Installation

    Execute the below command on your system to make security changes on your Database server. This will prompt some questions. The do the high security provide all answers to yes.

    sudo mysql_secure_installation
    

    Here you can enable/disable validate password plugin, Set required strength for passwords, remove anonymous users, disallow root login remotely, Remove test database and access to it and reload the reload privileges after applied changes.

    See the below output and action taken by me:

    Securing the MySQL server deployment.
    
    Enter password for user root:
    
    VALIDATE PASSWORD PLUGIN 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 plugin?
    
    Press y|Y for Yes, any other key for No: y
    
    There are three levels of password validation policy:
    
    LOW    Length >= 8
    MEDIUM Length >= 8, numeric, mixed case, and special characters
    STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
    
    Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
    Using existing password for root.
    
    Estimated strength of the password: 50
    Change the password for root ? ((Press y|Y for Yes, any other key for No) : y
    
    New password:
    
    Re-enter new password:
    
    Estimated strength of the password: 100
    Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
    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.
    
    Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
    Success.
    
    All done!
    

    Step 4 – Connect to MySQL

    The MySQL server has been installed on your system. Now connect to the MySQL database using the command line. Use root account password set in above step.

     mysql -u root -p
    
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 8
    Server version: 8.0.17 MySQL Community Server - GPL
