批量杀死MySQL连接

下面简述 2 种方法

㈠ 巧用 information_schema.processlist

[sql]
view plaincopyprint?

mysql> select concat('KILL ',id,';') from information_schema.processlist where user='root' into outfile '/tmp/killall.txt';

mysql> source /tmp/killall.txt;

㈡ 在 Bash 层用 AWK 实现

① 杀掉所有

[sql]
view plaincopyprint?

mysqladmin -uroot -p processlist|awk -F "|" '{print $2}'|xargs -n 1 mysqladmin -uroot -p kill

② 杀掉指定、比如：Rocky

[sql]
view plaincopyprint?

mysqladmin -uroot -p processlist|awk -F "|" '{if($3 == "Rocky")print $2}'|xargs -n 1 mysqladmin -uroot -p kill
