修改用户user2的主目录为/var/user2，把启动Shell修改为/bin/sh
举一反三
- 下面使用DELETE语句删除用户user2的语句中,正确的是 A: DELETE FROM mysql.user WHERE Host='localhost' AND User='user2'; B: DELETE FROM mysql.user WHILE Host='localhost' AND User='user2'; C: DELETE FROM mysql.user WHERE Host='localhost' OR User='user2'; D: DELETE FROM mysql.user WHILE Host='localhost' OR User='user2';
- 使用CREATE USER语句创建一个新用户,用户名为user2、密码为123 下面选项中,能实现上述功能的语句是 A: CREATE USER 'user2'@'localhost' IDENTIFIED BY '123'; B: CREATE USER user2@localhost IDENTIFIED BY 123; C: CREATE USER 'user2'@'localhost' IDENTIFIED TO '123'; D: CREATE USER user2@localhost IDENTIFIED TO '123';
- 创建一个用户，用户名user02，所属主要组群和次要组群均为stuff，用户家目录为/home/user2，用户登录shell为/bin/bash
- 创建一个用户,用户名为user02,所属私有组和标准组为stuff,用户家目录为/home/user2,用户登陆shell为/bin/bash,正确的操作是( )。
- 将用户user2的名称改为user3。
