apache2-mpm-itk will not successfully restart

Hey guys,

I am having some problems after installing apache2-mpm-itk on my Debian 5.4 server. From my understanding apache2-mpm-itk will run child processes as root until a http request is received. It then suid's to the username in the VirtualHost directive. This is all working fine, as I can see a few apache processes started by a specific user.

However, the problem is when I try to restart apache. It will kill all the processes running by root but wont kill any of the processes that have been suid'ed to another username.

When i attempt to restart I get this error:

Code:

charged:/etc/apache2# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
 failed!

If I do a "ps aux | grep apache" before and after I see all the root processes killed, but processes running as specified users from VritualHost directive remaining.

Now I am not an extreme linux power user, but I know a bit. So could you please post detail reponses.

regards,
Shayne

Hi Shayne,

You should be able to find the pid of whatever is running on port 80. Use:

netstat -nlp | grep :80

That should show you what is bound to that port so that you can kill it and get things started up again. Where it says number/httpd or number/apache2 is the pid that you need to kill.
