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.
 
#是否删除用于test的annoymous用户，如果在生产环境下建议删除
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.
 
#是否禁止root远程登录
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n
 
 ... skipping.
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.
 
#是否删除test数据库
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : n
 
... skipping.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
 
#是否让设置立即生效
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
 
All done!
