mysql批量kill进程

2017/06/17 mysql

##通过information_schema.processlist表中的连接信息生成需要处理掉的MySQL连接的语句临时文件,然后执行临时文件中生成的指令。 desc information_schema.processlist ; SELECT concat(‘KILL ‘,id,’;’) FROM information_schema.processlist WHERE user=’root’; SELECT concat(‘KILL ‘,id,’;’) FROM information_schema.processlist WHERE user=’root’ INTO OUTFILE ‘/tmp/a.txt’; source /tmp/a.txt;

/usr/local/mysql/bin/mysql -uroot -pbdweb..pw..1999yy -S /tmp/mysql.sock -e “show processlist” grep Query awk ‘{print “kill “$1”;”}’ > /tmp/kill.sql

/usr/local/mysql/bin/mysql -uroot -pbdweb..pw..1999yy -S /tmp/mysql.sock -e “source /tmp/kill.sql;”

##杀掉当前所有的MySQL连接 mysqladmin -uroot -p processlist|awk -F “|” ‘{print $2}’|xargs -n 1 mysqladmin -uroot -p kill

##通过SHEL脚本实现,杀掉锁定的MySQL连接 for id in mysqladmin processlist|grep -i locked|awk '{print $1}' do mysqladmin kill ${id} done

##通过Maatkit工具集中提供的mk-kill命令进行

#杀掉超过60秒的sql mk-kill -busy-time 60 -kill #如果你想先不杀,先看看有哪些sql运行超过60秒 mk-kill -busy-time 60 -print #如果你想杀掉,同时输出杀掉了哪些进程 mk-kill -busy-time 60 -print –kill
