使用mysqladmin杀死失控查询:

执行如下命令:

mysqladmin -uusername -ppassword pr

然后记下进程id。

mysqladmin -uusername -ppassword kill pid

失控查询应该不再消耗资源。

如果你有mysqladmin可用，你可以得到查询的列表:

> mysqladmin -uUSERNAME -pPASSWORD pr

+-----+------+-----------------+--------+---------+------+--------------+------------------+
| Id  | User | Host            | db     | Command | Time | State        | Info             |
+-----+------+-----------------+--------+---------+------+--------------+------------------+
| 137 | beet | localhost:53535 | people | Query   | 292  | Sending data | DELETE FROM      |
| 145 | root | localhost:55745 |        | Query   | 0    |              | show processlist |
+-----+------+-----------------+--------+---------+------+--------------+------------------+

然后你可以停止运行这个长时间查询的mysql进程:

> mysqladmin -uUSERNAME -pPASSWORD kill 137

连接mysql

mysql -uusername -p  -hhostname

显示完整的流程列表:

mysql> show full processlist;
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| Id      | User   | Host              | db      | Command | Time | State | Info             |
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| 9255451 | logreg | dmin001.ops:37651 | logdata | Query   |    0 | NULL  | show processlist |
+---------+--------+-------------------+---------+---------+------+-------+------------------+

终止特定的查询。id = 9255451

mysql> kill 9255451;

如果你的权限被拒绝，试试下面的SQL:

CALL mysql.rds_kill(9255451)

再补充一下

删除查询**Id** where Id是连接Id从显示processlist

如果您不想在运行某些应用程序时终止连接，则更可取。
