How do I kill all the processes in Mysql “show processlist”?

Question

Because I see a lot of processes there, and the \"time\" column shows big values for all of them.

Answer 1

#! /bin/bash
if [ $# != "1" ];then
    echo "Not enough arguments.";
    echo "Usage: killQueryByDB.sh <db_name>";
    exit;
fi;

DB=${1};
for i in `mysql -u <user> -h localhost ${DB} -p<password> -e "show processlist" | sed 's/\(^[0-9]*\).*/\1/'`; do
    echo "Killing query ${i}";
    mysql -u <user> -h localhost ${DB} -p<password> -e "kill query ${i}";
done;

Answer 2

We can do it by MySQL Workbench. Just execute this:

kill id;

Example:

kill 13412

That will remove it.

Answer 3

I used the command flush tables to kill all inactive connections which where actually the mass problem.

Answer 4

Query 1 select concat('KILL ',id,';') from information_schema.processlist where user='username' into outfile '/tmp/a.txt';

Query 2 source a.txt

This will enable you to kill all the queries in show processlist by specific user.
