在安裝mysql後，會安裝一個名為 mysql_secure_installation的程式，此程式主要完成以下幾個功能：

1、為root使用者佈建密碼；

2、刪除匿名帳號；

3、取消root使用者遠程登入；

4、刪除test庫和對test庫的存取權限；

5、重新整理授權表使修改生效；

通過這幾項加固設定能夠提高mysql庫的安全。

執行例子：（注意：其中//開頭的行是人為添加的注釋）

fuckids@debian-IDS:~/Autosnort - Debian$ /usr/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

//1、為root使用者佈建密碼；

Change the root password? [Y/n] n
... 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.

//2、刪除匿名帳號；

Remove anonymous users? [Y/n] 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.

//3、取消root使用者遠程登入；

Disallow root login remotely? [Y/n] 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.
//4、刪除test庫和對test庫的存取權限；
Remove test database and access to it? [Y/n] y
- Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
... Failed! Not critical, keep moving...
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
//5、重新整理授權表使修改生效；
Reload privilege tables now? [Y/n] n
... skipping.

Cleaning up...

All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!
