Experimental twelve database security
First, the Experiment:
1, the database user account creation and deletion
2, the database user rights granted and recover
Second, the pilot project: staff management database
Staff management for enterprise database management, database named YGGL in, YGGL database consists of three tables: Employees (employee information table), Departments (department information table), Salary (staff salaries Fact Sheet).
Third, the experimental procedures required to complete the following :( command)
1, create a database user user_1 and user_2, passwords are 123456 (assuming that the server name is localhost), and view both user in the user table;
2
(1) to change the name of the user user_2 user2;
(2) modification of the user password is user_1 123;
3, delete user user2;
4, log on as a user user_1 mysql server, performs several database operations, to see what the user has permission?
5, grant users permissions to YGGL user_1 query the database Employees table as a user login user_1 mysql server, verify that the authority;
6, grant users permissions to YGGL u1 query the database Employees table, log on as a user u1 mysql server, verify that the permissions;.
7, user_1 grant users to query and modify permissions on the Salary table and allow the permissions granted to other users;
8, a user's login user_1 mysql server and authorize all rights user_1 to u1 users;
.
9, log on as a user u1 mysql server, verify that it has to query and modify permissions on the Salary table;
10, recovered user_1 query privileges on the Salary table as a user login user_1 mysql server, verify that the user can query the Salary table;
11、 以u1的用户身份登录mysql服务器，验证其是否还可以对Salary表进行查询。
12、 授予u1对Departments表中备注列的修改权限；
13、 授予u1对YGGL数据库中所有表的查询权限，并以u1的用户身份登录mysql服务器，验证该权限；
14、 授予u1创建数据库表的权限，并以u1的用户身份登录mysql服务器，验证该权限。
