 7 VALIDATE PASSWORD PLUGIN can be used to test passwords
 8 and improve security. It checks the strength of password
 9 and allows the users to set only those passwords which are
10 secure enough. Would you like to setup VALIDATE PASSWORD plugin?
11
12 Press y|Y for Yes, any other key for No: y                  #需要修改密码，所以输入y
13
14 There are three levels of password validation policy:
15
16 LOW    Length >= 8
17 MEDIUM Length >= 8, numeric, mixed case, and special characters
18 STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file
19
20 Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2          #设置密码复杂度为强
21 Please set the password for root here.
22
23 New password:
24
25 Re-enter new password:                                      #输入2次新密码
26
27 Estimated strength of the password: 100
28 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
29 By default, a MySQL installation has an anonymous user,
30 allowing anyone to log into MySQL without having to have
31 a user account created for them. This is intended only for
32 testing, and to make the installation go a bit smoother.
33 You should remove them before moving into a production
34 environment.
35
36 Remove anonymous users? (Press y|Y for Yes, any other key for No) : y   #删除匿名用户
37 Success.
38
39
40 Normally, root should only be allowed to connect from
41 'localhost'. This ensures that someone cannot guess at
42 the root password from the network.
43
44 Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y     #禁止root远程登录
45
46  ... skipping.
47 By default, MySQL comes with a database named 'test' that
48 anyone can access. This is also intended only for testing,
49 and should be removed before moving into a production
50 environment.
51
52
53 Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y  #删除测试数据库
54  - Dropping test database...
55 Success.
56
57  - Removing privileges on test database...
58 Success.
59
60 Reloading the privilege tables will ensure that all changes
61 made so far will take effect immediately.
62
63 Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y  #重新加载权限表
64 Success.
65
66 All done!
