#4
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 (我的选项，选择N，允许root远程连接)

#5
By default, MySQL comes with a database named 'test' that anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (选择N，不删除test数据库)

#6
Reloading the privilege tables will ensure that all changes made so far will take effect immediately.
