This is the error message I get when I try to run nginx:


nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] still could not bind()


I have disabled apache, so it's not that. Previous to this, I uninstalled nginx (using mac osx snow leopard), but 0.0.0.0 and 127.0.0.1 were still displaying "Welcome to nginx". I then re-installed nginx and I have been trying to run it, but I am getting these errors.

I've tried checking what is on port 80 with this:
$ sudo lsof -i:80
but nothing is returned.

0.0.0.0:80 displays: "404 Not Found nginx/1.0.6"

Output of "ps ax -o pid,ppid,%cpu,vsz,wchan,command|egrep '(nginx|PID)'"

nginx.conf can be found here: http://pastebin.com/Rq8vKHXn

Would anyone happen to know how to resolve this?

Thank you in advance.
