Linux script implements bulk SSH remote kill process

Preface :

The company has more than 150 servers, on each server deployed script, and then this script has been running, there are some problems, now to remote batch to kill these processes, tossing for half a day, the following script can be implemented

Script :

#/bin/bash

For i in ' cat/home/zhangdl/old/ip.txt | Grep-i-V Port | awk ' {print $} '

Do

Ssh-p 888 $i "PS aux | Grep-v grep | grep amateurback.sh | awk ' {print \$2} ' | Xargs Kill "

If [$? = = 1];then

echo $i >>/home/zhangdl/old/error.txt

Fi

Done

parsing :

(1) Ip.txt inside the format is as follows, inconvenient words use XXX instead of

XXX base 61.190.XX. XX Xxxjidi xxx,xxx,xxx,xxx,xxx

(2) For security, the SSH port is set to another port, assuming this is 888 port, if it is 22 port, will be "xxx base (Port 22)", the remaining is the other port

(3) After filtering the IP to traverse

Ssh-p 888 "PS aux | Grep-v grep | grep amaterback.sh | awk ' {print \$2} ' Xargs kill '

Select the process number to Xargs kill, SSH combined with awk to use the $ symbol escaped, here no matter how many processes you have, as long as the conditions, will kill off.
