如何查看mysql的用户及授权

标签：mysql 权限

1）查看mysql中存在的用户

mysql> select user,host from mysql.user;
+------------+--------------------------+
| user       | host                     |
+------------+--------------------------+
| oldgirl    | %                        |
| wan        | %                        |
| wanlong    | %                        |
| rep        | 10.10.10.%               |
| root       | 10.10.10.%               |
| wan        | 10.10.10.%               |
| wanlong    | 10.10.10.%               |
| oldgril123 | 10.10.10.0/255.255.255.0 |
| root       | 127.0.0.1                |
| root       | ::1                      |
| root       | C67-X64-A8               |
| backup     | localhost                |
| root       | localhost                |
+------------+--------------------------+
13 rows in set (0.00 sec)

2）如何查看用户的授权

mysql> show grants for ‘wanlong‘@‘10.10.10.%‘;
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for wanlong@10.10.10.%                                                                                                                                                                                                                                                                                                                              |
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT SELECT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE ON *.* TO ‘wanlong‘@‘10.10.10.%‘ |
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

3）all privileges具备哪些权限

a、创建测试账号并进行授权：

mysql> create user wanlong identified by ‘wanlong‘;
Query OK, 0 rows affected (0.01 sec)
mysql> grant all privileges on *.* to ‘wanlong‘@‘10.10.10.%‘;
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for ‘wanlong‘@‘10.10.10.%‘;
+-------------------------------------------------------+
| Grants for wanlong@10.10.10.%                         |
+-------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO ‘wanlong‘@‘10.10.10.%‘ |
+-------------------------------------------------------+
1 row in set (0.00 sec)

b、回收insert权限，并查看用户的权限

mysql> revoke insert on *.* from ‘wanlong‘@‘10.10.10.%‘;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> show grants for ‘wanlong‘@‘10.10.10.%‘;
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for wanlong@10.10.10.%                                                                                                                                                                                                                                                                                                                              |
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT SELECT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE ON *.* TO ‘wanlong‘@‘10.10.10.%‘ |
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

c、导出文件，并查看授权（all privileges还需要添加刚才使用revoke取消的insert授权）

# mysql -uroot -predhat12345 -S /data/3306/mysql.sock -e "show grants for ‘wanlong‘@‘10.10.10.%‘;"|grep -i grant|tail -1|tr ‘,‘ ‘\n‘>all.privileges
查看all privileges具备的权限：
# cat all.privileges 
GRANT SELECT
 UPDATE
 DELETE
 CREATE
 DROP
 RELOAD
 SHUTDOWN
 PROCESS
 FILE
 REFERENCES
 INDEX
 ALTER
 SHOW DATABASES
 SUPER
 CREATE TEMPORARY TABLES
 LOCK TABLES
 EXECUTE
 REPLICATION SLAVE
 REPLICATION CLIENT
 CREATE VIEW
 SHOW VIEW
 CREATE ROUTINE
 ALTER ROUTINE
 CREATE USER
 EVENT
 TRIGGER
 CREATE TABLESPACE ON *.* TO ‘wanlong‘@‘10.10.10.%‘
