MySQLKillsleep process _ MySQL

If the MySQLKillsleep process is idle, study it slowly...

--------------------------------------------------------

Mysql> SELECT concat ('Kill ', id,'; ') FROM information_schema.processlist WHERE user = 'root' INTO outfile'/tmp/a.txt'; Query OK, 2 rows affected (0.00 sec) mysql> source/tmp/a.txt; Query OK, 0 rows affected (0.00 sec)

#! /Bin/bash
# While ["2"-gt "1"]
# Do
Log_command = 'mysqladmin processlist | grep-I sleep | wc-L'
Date = 'date + % Y % m % d/[% H: % M: % S]'
# Echo $ log_command
If ["$ log_command"-gt 250]
Then
For I in 'mysqladmin processlist | grep-I sleep | awk '{print $2 }''
Do
Mysqladmin kill $ I

# Done

Note that the user executing mysqladmin directly runs mysqladmin processlist | grep-I sleep | wc-l on the command line, which is actually-uroot. The user logging on to the server is used to execute this script on the command line. While crontab is used for execution, although it is edited as the root crontab, it is not a root user during execution, and I do not know which one is used. It is best to add su-root to the crontab command.
