-===== Workaround for slow HTTPD shutdown ===== 
-In some RHEL/CentOS versions Apache HTTPD shutsdown or restarts itself very slowly. It is caused by [[https://bugzilla.redhat.com/show_bug.cgi?id=906321]]. 
-Workaround is to edit '''/usr/lib/systemd/system/httpd.service''' and add the option: 
-<code> 
-KillMode=none 
-</code> 
-Then reload systemd: 
- 
-<code> 
-systemctl daemon-reload 
-</code> 
- 
-It is absolutely correct to create new versions of unity in /etc, that has the option: 
- 
-<code> 
-cp /usr/lib/systemd/system/httpd.service /etc/systemd/system/httpd.service 
-vim /etc/systemd/system/httpd.service # add parametr KillMode=none 
-systemctl daemon-reload 
-</code> 
- 
-The patch of httpd should come soon so the first option is OK too.
