我們在安裝完MySql服務器，設置好MySql的root用戶密碼后，就直接開始使用了，其實這樣的MySql服務器還存在著一些不安全因素，本篇演示一下用命令mysql_secure_installation來安全初始化我們的MySql服務器。

01?[root@test ~]# /usr/bin/mysql_secure_installation

02?NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

03?????? SERVERS IN PRODUCTION USE!? PLEASE READ EACH STEP CAREFULLY!

04

05?In order to log into MySQL to secure it, we'll need the current

06?password for the root user.? If you've just installed MySQL, and

07?you haven't set the root password yet, the password will be blank,

08?so you should just press enter here.

09

10?Enter current password for root (enter for none):

11?OK, successfully used password, moving on...

12

13?Setting the root password ensures that nobody can log into the MySQL

14?root user without the proper authorisation.

15

16?Set root password? [Y/n] Y??

17?New password:

18?Re-enter new password:

19?Password updated successfully!

20?Reloading privilege tables..

21? ... Success!

22

23?By default, a MySQL installation has an anonymous user, allowing anyone

24?to log into MySQL without having to have a user account created for

25?them.? This is intended only for testing, and to make the installation

26?go a bit smoother.? You should remove them before moving into a

27?production environment.

28

29?Remove anonymous users? [Y/n] Y

30? ... Success!

31

32?Normally, root should only be allowed to connect from 'localhost'.? This

33?ensures that someone cannot guess at the root password from the network.

34

35?Disallow root login remotely? [Y/n] Y

36? ... Success!

37

38?By default, MySQL comes with a database named 'test' that anyone can

39?access.? This is also intended only for testing, and should be removed

40?before moving into a production environment.

41

42?Remove test database and access to it? [Y/n]

43? - Dropping test database...

44? ... Success!

45? - Removing privileges on test database...

46? ... Success!

47

48?Reloading the privilege tables will ensure that all changes made so far

49?will take effect immediately.

50

51?Reload privilege tables now? [Y/n] Y

52? ... Success!

53

54?Cleaning up...

55

56?All done!? If you've completed all of the above steps, your MySQL

57?installation should now be secure.

58

59?Thanks for using MySQL!
