在使用mysql數(shù)據(jù)庫經(jīng)常都會遇到這么一個問題，其它用戶定義的存儲過程，現(xiàn)在使用另一個用戶卻無法修改或者刪除等；正常情況下存儲過程的定義者對它有修改、刪除的權(quán)限；但是其它的用戶就要相于的授權(quán)，不然無法查看、調(diào)用；
mysql 中使用用戶A創(chuàng)建一個存儲過程,現(xiàn)在想通過另一個用戶B來修改A創(chuàng)建的存儲過程；以下記錄就是基于這樣的情況產(chǎn)生的；
用戶A對OTO3庫的權(quán)限：
mysql> show grants for 'a'@'%';
+---------------------------------------------------+
| Grants for a@% |
+---------------------------------------------------+
| GRANT USAGE ON *.* TO 'a'@'%' |
| GRANT ALL PRIVILEGES ON `OTO3`.* TO 'a'@'%' |
+---------------------------------------------------+
2 rows in set (0.00 sec)
用戶B的權(quán)限：
mysql> show grants for 'swper'@'%';
+----------------------------------------------------------------------+
| Grants for swper@% |
+----------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'swper'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER ON `OTO3`.* TO 'swper'@'%' |
+----------------------------------------------------------------------+
2 rows in set (0.00 sec)
以用戶B的身份登陸Mysql操作；
[root@mysql ~]# mysql -h10.0.10.110 -uswper -p123456
查存儲過程列表時就提示沒有權(quán)限了：
mysql> select `name` from mysql.proc where db = 'OTO3' and `type` = 'PROCEDURE';
ERROR 1142 (42000): SELECT command denied to user 'swper'@'mysql' for table 'proc'
以root身份給B用戶添加一個查看存儲過程的權(quán)限：
mysql> grant select on mysql.proc to 'swper'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for 'swper'@'%';
+----------------------------------------------------------------------+
| Grants for swper@% |
+----------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'swper'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER ON `OTO3`.* TO 'swper'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'swper'@'%' |
+----------------------------------------------------------------------+
3 rows in set (0.00 sec)
再回到B用戶里查看存儲過程列表：
mysql> select `name` from mysql.proc where db = 'OTO3' and `type` = 'PROCEDURE';
+------------------------+
| name |
+------------------------+
| proc_cs |
+------------------------+
1 rows in set (0.00 sec)
此時發(fā)現(xiàn)多了一個mysql庫，但只有對mysql.proc有查詢權(quán)限：
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| OTO3 |
| mysql |
+--------------------+
3 rows in set (0.00 sec)
mysql庫中只有一個表：proc
mysql> use mysql
mysql> show tables;
+-----------------+
| Tables_in_mysql |
+-----------------+
| proc |
+-----------------+
1 row in set (0.00 sec)
同樣也可以看到存儲過程的詳細信息：
mysql> show create procedure proc_cs\G
*************************** 1. row ***************************
Procedure: proc_cs
sql_mode: STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Create Procedure: CREATE DEFINER=`a`@`%` PROCEDURE `proc_cs`()
BEGIN
嘗試修改存儲過程的配置：
mysql> ALTER PROCEDURE proc_cs MODIFIES SQL DATA SQL SECURITY INVOKER;
ERROR 1370 (42000): alter routine command denied to user 'b'@'%' for routine 'OTO3.proc_cs'
為了方便查看在Navicat工具上嘗試修改存儲過程，在保存的時候報如下權(quán)限問題：
1227 -Access denied;you need(at least one of)the SUPER privilege(s) for this operation
嘗試添加一個存儲過程，報權(quán)限信息：
1044 - Access denied for user ‘b'@'%' to database ‘OTO3'
這里表示b用戶沒有對OTO3有授權(quán)存儲過程的修改權(quán)限；
以B用戶嘗試調(diào)用一下存儲過程：
Procedure execution failed
1370 - execute command denied to user ‘b'@'%' for routine ‘OTO3.proc_cs'
這里很明顯連運行權(quán)限也沒有；
嘗試刪除原有的a用戶定義的存儲過程，也會報權(quán)限信息，如下：
1370 - alter routine command denied to user ‘b'@'%' for routine ‘OTO3.proc_cs'
可以看出B用戶連調(diào)用存儲過程的權(quán)限都沒有，這里先加入執(zhí)行權(quán)限：
接下來添加一個執(zhí)行存儲過程的權(quán)限：
mysql> grant execute on OTO3.* to 'b'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for 'b'@'%';
+-------------------------------------------------------------------------------+
| Grants for b@% |
+-------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'b'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER, EXECUTE ON `OTO3`.* TO 'b'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'b'@'%' |
+-------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
再次執(zhí)行一下存儲過程，發(fā)現(xiàn)成功了；
時間: 0.080ms
Procedure executed successfully
受影響的行: 0
那再添加一下創(chuàng)建添加存儲過程的權(quán)限：
mysql> grant CREATE ROUTINE on OTO3.* to 'b'@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> show grants for 'b'@'%';
+-----------------------------------------------------------------------------------------------+
| Grants for b@% |
+-----------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'b'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER, EXECUTE, CREATE ROUTINE ON `OTO3`.* TO 'b'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'b'@'%' |
+-----------------------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
上面添加權(quán)限后就可以創(chuàng)建存儲過程了;
CREATE DEFINER=`b`@`%` PROCEDURE `aaaa`()
BEGIN
#Routine body goes here...
SELECT * from mysql.user;
END
但是自己創(chuàng)建的都無法刪除；
1370 - alter routine command denied to user ‘b'@'%' for routine ‘OTO3.aaaa'
接下來再添加一個修改的權(quán)限，也可以刪除的哦；
mysql> grant alter ROUTINE on OTO3.* to 'b'@'%';
Query OK, 0 rows affected (0.01 sec)
查看用戶權(quán)限
mysql> show grants for 'b'@'%';
+--------------------------------------------------------------------------------------------------------------+
| Grants for b@% |
+--------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'b'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER, EXECUTE, CREATE ROUTINE, ALTER ROUTINE ON `OTO3`.* TO 'b'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'b'@'%' |
+--------------------------------------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
上面添加完alter ROUTINE權(quán)限后就可以對OTO3所有的存儲過程有刪除權(quán)限[自己定義的增、刪、改]，別人定義的可以刪除，但是還不能修改；修改別人定義的存儲過程會有如下提示：
1227 - Access denied; you need (at least one of)the SUPER privilege(s) for this operation
這里說明一下這個SUPER權(quán)限在哪里？通過查看用戶權(quán)限原來在這里：
mysql> select * from mysql.user where user='b'\G
*************************** 1. row ***************************
Host: %
User: b
Select_priv: N
Insert_priv: N
Update_priv: N

password_expired: N
password_last_changed: 2017-03-06 11:37:35
password_lifetime: NULL
account_locked: N
1 row in set (0.00 sec)
嘗試添加一下這個SUPER權(quán)限看看：
mysql> grant SUPER on OTO3.* to 'b'@'%';
ERROR 1221 (HY000): Incorrect usage of DB GRANT and GLOBAL PRIVILEGES
mysql> grant SUPER on *.* to 'b'@'%';
Query OK, 0 rows affected (0.00 sec)
不能對指定的庫執(zhí)行這個權(quán)限，因為SUPER為全局的就是整個mysql的權(quán)限；
mysql> show grants for 'swper'@'%';
+--------------------------------------------------------------------------------------------------------------+
| Grants for swper@% |
+--------------------------------------------------------------------------------------------------------------+
| GRANT SUPER ON *.* TO 'swper'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER, EXECUTE, CREATE ROUTINE, ALTER ROUTINE ON `OTO3`.* TO 'swper'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'swper'@'%' |
+--------------------------------------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
再次檢查時會發(fā)現(xiàn) Super_priv: Y 變化了；再修改一下別人定義的存儲過程；
mysql> select * from mysql.user where user='b'\G
查看所有數(shù)據(jù)庫，發(fā)現(xiàn)mysql庫只有一張proc表有讀取的權(quán)限，SUPER并非我所想象中那么強大；
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| OTO3 |
| mysql |
+--------------------+
3 rows in set (0.00 sec)
仔細觀看會發(fā)現(xiàn)執(zhí)行語句：
mysql> select * from mysql.user where user='b'\G
可以看到有 Create_routine_priv: N和 Alter_routine_priv: N 這兩個明顯就是對存儲過程的權(quán)限嘛，能不能不用SUPER而使用這兩個權(quán)限呢？
回收一下這個SUPER權(quán)限；
mysql> revoke super on *.* from 'b'@'%';
Query OK, 0 rows affected (0.01 sec)
再添加Alter_routine_priv，Create_routine_priv
mysql> grant alter routine,create routine on *.* to 'b'@'%';
Query OK, 0 rows affected (0.00 sec)
查看用戶b權(quán)限
mysql> show grants for 'b'@'%';
+--------------------------------------------------------------------------------------------------------------+
| Grants for b@% |
+--------------------------------------------------------------------------------------------------------------+
| GRANT CREATE ROUTINE, ALTER ROUTINE ON *.* TO 'b'@'%' |
| GRANT SELECT, UPDATE, DELETE, DROP, ALTER, EXECUTE, CREATE ROUTINE, ALTER ROUTINE ON `OTO3`.* TO 'b'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'b'@'%' |
+--------------------------------------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
發(fā)現(xiàn)還是報相同的權(quán)限問題：
1227 - Access denied; you need (at least one of)the SUPER privilege(s) for this operation
執(zhí)行上面權(quán)限后發(fā)現(xiàn)，可以看到其它的系統(tǒng)庫：[例如sys庫也有存儲過程，由于這兩個權(quán)限是全局的]
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| OTO3 |
| mysql |
| performance_schema |
| sys |
| test |
+--------------------+
6 rows in set (0.00 sec)
這兩個權(quán)限更大，連系統(tǒng)庫sys中的存儲過程都能看到，甚至修改刪除，非常危險；決定再次回收權(quán)限
create routine,alter routine；
mysql> revoke create routine,alter routine on *.* from 'b'@'%';
還是使用SUPER權(quán)限比較安全；
通過上面的測試得出以下結(jié)論：
- 查看存儲過程權(quán)限：SELECT #是對mysql.proc表的權(quán)限；
- 執(zhí)行存儲過程權(quán)限：EXECUTE #是對指定數(shù)據(jù)庫的權(quán)限；
- 創(chuàng)建存儲過程權(quán)限：CREATE ROUTINE #是對指定數(shù)據(jù)庫的權(quán)限；
- 修改存儲過程權(quán)限：ALTER ROUTINE #是對指定數(shù)據(jù)庫的中自己定義的存儲過程；
- 修改別人定義的存儲過程權(quán)限：SUPER #是對全局整個mysql的權(quán)限；
簡來說用戶A在數(shù)據(jù)庫OTO3中定義了一個存儲過程，現(xiàn)在想用用戶B來執(zhí)行、修改存儲過程,需要對用戶B添加以下權(quán)限：
GRANT SELECT ON MYSQL.PROC TO 'B';
GRANT EXECUTE, CREATE ROUTINE, ALTER ROUTINE ON `OTO3`.* TO 'B';
GRANT SUPER ON *.* TO 'B';
所以用戶B的最基本的權(quán)限：
mysql> show grants for 'b'@'%';
+----------------------------------------------------------------------------------------+
| Grants for b@% |
+----------------------------------------------------------------------------------------+
| GRANT SUPER ON *.* TO 'b'@'%' |
| GRANT SELECT, ALTER, EXECUTE, CREATE ROUTINE, ALTER ROUTINE ON `OTO3`.* TO 'b'@'%' |
| GRANT SELECT ON `mysql`.`proc` TO 'b'@'%' |
+----------------------------------------------------------------------------------------+
3 rows in set (0.00 sec)
至此，對于Mysql中以另的用戶修改其它人定義的存儲過程權(quán)限也就非常的顯白了；
如果不是以另一個用戶身份調(diào)用存儲過程，可以使用root權(quán)限修改存儲過程的定義者; 這樣就等于linux里的所有者權(quán)限變更了；
update mysql.proc set DEFINER='b'@'%' WHERE NAME='proc_cs' AND db='OTO3';
