Unable to bind apache2 to port 80

Hi all, I’m getting some problems with apache2, when I tried to edit the config in Yast2 I got an error telling me that it “cannot adjust ‘apache2’ service.”

Having tried to start apache from XTerm I got this error:

/etc/init.d/apache2 start
Starting httpd2 (prefork) (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
startproc: exit status of parent of /usr/sbin/httpd2-prefork: 1 failed

So, I tried the obvious, I looked for something else running on port 80

I did a netstat and nothing was listening on port 80

I ran lsof -i | grep :http and got no results

I tried ps ax | grep httpd and got pts/1 S+ 0:00 grep httpd

So my question is, how else can I find out what is stopping apache from running?

Thanks.

As root, use the command

fuser 80/tcp

to find the PID of the process with the open port. If this produces no output, the command

netstat -ant | grep :80

will show more information about the socket.
