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) : ... 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) : ... skipping.
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!
