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 #是否删除匿名用户&＃xff0c;输入Y

Success.

Normally, root should only be allowed to connect from &＃39;localhost&＃39;. 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远程登录&＃xff0c;输入Y

Success.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y #是否删除test库和对它的访问权限&＃xff0c;输入Y
