数据库偶尔会响应很慢，看着好像挂掉了，检查进程发现有大量查询语句把表锁住了，提供一个脚本给大家解决锁表导致的Mysql异常。

#!/bin/sh
while :
do
n=`/usr/local/webserver/mysql/bin/mysql -uroot -p"kk41-,dnkkedkd8>/ee" -e 'show processlist;' | grep -i locked |grep -i search_keyword | wc -l`
date=`date +%Y%m%d[%H:%M:%S]`
echo $n
if [ "$n" -gt 50 ]
then
    for i in `/usr/local/webserver/mysql/bin/mysql -uroot -p"kk41-,dnkkedkd8>/ee" processlist | grep -i locked |grep -i search_keyword | awk '{print $2}'`
    do
      /usr/local/webserver/mysql/bin/mysql -uroot -p"kk41-,dnkkedkd8>/ee" kill $i
    done
    echo "killed it" >> /tmp/sleep.log
    echo "$date : $n" >> /tmp/sleep.log
fi
sleep 10
done
