takizo, not takezo

Sometime I have problem killing all apache processes or PID on a high load web server even though the service has been stopped. One of the quick way to kill all the services is using ps command.

shell> ps ax | grep http
  795  ??  S      0:01.03 /usr/local/sbin/httpd -DSSL
 4280  ??  S      0:00.59 /usr/local/sbin/httpd -DSSL
 4796  ??  S      0:00.47 /usr/local/sbin/httpd -DSSL
 6219  ??  S      0:01.36 /usr/local/sbin/httpd -DSSL
10459  ??  S      0:01.34 /usr/local/sbin/httpd -DSSL
16048  ??  S      0:00.64 /usr/local/sbin/httpd -DSSL
16050  ??  S      0:00.43 /usr/local/sbin/httpd -DSSL
16562  ??  S      0:00.39 /usr/local/sbin/httpd -DSSL
19888  ??  S      0:00.47 /usr/local/sbin/httpd -DSSL
22362  ??  S      0:00.10 /usr/local/sbin/httpd -DSSL
92166  ??  Ss     0:49.08 /usr/local/sbin/httpd -DSSL

Try to grep httpd processes which currently running on your server

shell> ps ax | grep http | awk '{print $1}'
795
4280
4796
6219
10459
16048
16050
16562
19888
22362
92166
24995

use awk command to grab the process IDs

shell> ps ax | grep http | awk '{print $1}' | xargs kill

using xrgs command to kill all the process ID we have gather earlier.

This is a handful command instead of killing the process ID one by one.
A clean kill.
