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 (删除匿名用户)
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 (禁止 root 用户远程登录)
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 (删除测试数据库)
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 (重新加载权限表)
Success.
All done!
