一、用户

1.创建用户

CREATE USER 'test1'@'localhost' identified BY 'test1';

2.删除用户

DROP USER 'test2'@'localhost';

二、权限分配

1.查询用户权限

SHOW GRANTS FOR 'test1'@'localhost';

2.分配权限

# 分配用户所有权限在for_end_test库的test1表
GRANT ALL PRIVILEGES ON for_end_test.test1 TO 'test1'@'localhost';
# 分配用户可查询权限在for_end_test库的test1表
GRANT SELECT ON for_end_test.test1 TO 'test1'@'localhost';

3.移除权限

# 收回用户可查询权限在for_end_test库的test1表
REVOKE SELECT ON for_end_test.test1 FROM 'test1'@'localhost';

4.权限生效

FLUSH PRIVILEGES;
