mysql kill process解决死锁

1、查看进程列表，

show processlist;
+--------+--------+--------------------+----------+---------+------+----------+------------------+
 | Id     | User   | Host               | db       | Command | Time | State    | Info             |
 +--------+--------+--------------------+----------+---------+------+----------+------------------+
 |      8 | remote | 10.16.30.96:36592  | activity | Sleep   |  239 |          | NULL             |
 | 396749 | remote | 172.17.1.122:53028 | activity | Sleep   | 1966 |          | NULL             |
 | 397104 | remote | 172.17.3.211:52666 | activity | Sleep   |    7 |          | NULL             |
 | 397177 | remote | 172.17.3.211:52819 | activity | Sleep   | 7366 |          | NULL             |
 | 397267 | remote | 172.17.1.122:55728 | activity | Sleep   | 5741 |          | NULL             |
 | 397268 | remote | 172.17.1.122:55730 | activity | Sleep   | 7849 |          | NULL             |
 | 397287 | remote | 172.17.3.150:57151 | activity | Sleep   | 7128 |          | NULL             |
 | 397294 | remote | 172.17.3.68:53158  | activity | Sleep   | 2882 |          | NULL             |
 | 397296 | remote | 172.17.3.68:53160  | NULL     | Sleep   | 6492 |          | NULL             |

2、 查询语句把表锁住了, 赶紧找出第一个Locked的thread_id, 在​​MySQL​​的shell里面执行.

kill  id

#!/bin/bash
  

  mysql
   -
  u
   
  root
   -
  e
   
  "
  show processlist
  "
   | 
  grep
   -
  i
   
  "
  Locked
  "
   >> 
  locked_log
  .
  txt
  


  for
   
  line
   
  in
   
  `
  cat locked_log.txt | awk '{print 
  $1
  }'
  `
  

  do
   
    
  echo
   
  "
  kill 
  $line
  ;
  "
   >> 
  kill_thread_id
  .
  sql
  

  done

现在kill_thread_id.sql的内容像这个样子

kill   66402982 ;
kill   66402983 ;
kill   66402986 ;
kill   66402991 ;
.....

好了, 我们在mysql的shell中执行, 就可以把所有锁表的进程杀死了.

mysql
  >
  source
   
  kill_thread_id
  .
  sql

当然了, 也可以一行搞定
 
  for id in `mysqladmin processlist | grep -i locked | awk '{print $1}'`
do
    mysqladmin kill ${id}
done
