六、权限
1、先建用户，然后再授权
mysql> create user benet@‘localhost‘ identified by ‘pwd@123‘;
Query OK, 0 rows affected (0.22 sec)
mysql> show grants for ‘benet‘@‘localhost‘;
+--------------------------------------------------------------------------------------------------------------+
| Grants for benet@ localhost |
+--------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO ‘benet‘@‘ localhost ‘ IDENTIFIED BY PASSWORD ‘*760F60073FD235571A5260444301DB22136ED604‘ |
+--------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> grant all on benet_gbk.* to benet@‘ localhost ‘;
Query OK, 0 rows affected (0.22 sec)
mysql> show grants for ‘benet‘@‘ localhost ‘;
+--------------------------------------------------------------------------------------------------------------+
| Grants for benet@ localhost |
+--------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO ‘benet‘@‘ localhost ‘ IDENTIFIED BY PASSWORD ‘*760F60073FD235571A5260444301DB22136ED604‘ |
| GRANT ALL PRIVILEGES ON `benet_gbk`.* TO ‘benet‘@‘ localhost ‘ |
+--------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql>
2、直接授权法
mysql> grant all on benet_gbk.* to benet1@‘localhost‘ identified by ‘pwd@123‘;
Query OK, 0 rows affected (0.01 sec)
mysql> show grants for ‘benet1‘@‘localhos‘;
+---------------------------------------------------------------------------------------------------------------+
| Grants for benet1@localhos |
+---------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO ‘benet1‘@‘127.0.0.1‘ IDENTIFIED BY PASSWORD ‘*760F60073FD235571A5260444301DB22136ED604‘ |
| GRANT ALL PRIVILEGES ON `benet_gbk`.* TO ‘benet1‘@‘localhos‘ |
+---------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
3、授权bdqn用户在192.168.1.0/24网段可以远程连接数据库
mysql> grant all on *.* to bdqn@‘192.168.1.%‘ identified by ‘pwd@123‘;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> select user,host
-> from user;
+--------+-------------+
| user | host |
+--------+-------------+
| benet | 127.0.0.1 |
| benet1 | 127.0.0.1 |
| root | 127.0.0.1 |
| bdqn | 192.168.1.% |
+--------+-------------+
4 rows in set (0.00 sec)
[root@localhost ~]# mysql -ubdqn -ppwd@123 -h 192.168.1.101

查看all权限都包括哪些权限，先收回一个，再查看
mysql>mysql> revoke insert on benet_gbk.* from benet@‘localhost‘;
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for benet@‘ localhost ‘;
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
