# mysql_secure_installation Securing the MySQL server deployment. Enter password for user root: 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? # Enable/disable password quality check 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 # Select strength if password quality check is enabled Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0 ←May be optional for each Using existing password for root. # Set MySQL root password Estimated strength of the password: 100 Change the password for root ?

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. # Whether to remove anonymous users or not 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. # Disable/enable remote login for root user 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. # Whether to delete the test database or not 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. # Whether to reload privilege information or not Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y Success. All done! |
