某个初级dba误删index,mysql漫山遍野全是10S以上的慢sql,mysql服务被hang住了,而且慢sql不断在增加中,如果手动在mysql界面kill的话,根本来不及,这个时候,shell就必须要出手了,如下的shell脚本,大家可以参考:
#It is used to kill processlist of mysql sleep #!/bin/sh while : do n=`mysqladmin processlist -uadmin -pxxxxx|grep -i sleep |wc -l` date=`date +%Y%m%d[%H:%M:%S]` echo $n if [ "$n" -gt 10 ] then for i in `mysqladmin processlist -uadmin -pxxxxxx|grep -i sleep |awk '{print $2}'` do mysqladmin -uadmin -pxxxxxx kill $i done echo "sleep is too many I killed it " >> /tmp/sleep.log echo "$date : $n" >> /tmp/sleep.log fi sleep 1 done
最后,赶紧添加上合适的索引!
