How do I get ngix to stop listening on port 80?

Question

I'm running a node.js webserver on an Amazon Linux EC2, but I can't listen on port 80 because there's an nginx server listening on that port:

[ec2-user@ip-172-31-39-178 server]$ sudo netstat -tulpn

I don't know if I should just delete nginx (Not sure where to find it, if I were to try), or turn it off, or something like that. I don't use an nginx web-server, I guess it came packaged with the Amazon EC2.

I tried this, but it didn't work:

 sudo rm -f -R /usr/local/nginx && rm -f /usr/local/sbin/nginx

I will say right from the start I do not know Amazon Linux EC2, but I did do a bit of research to try and help.

You should be able to stop nginx with:

nginx -s stop

You should be able to stop it from starting on reboot with:

chkconfig nginx off

It may be that you need to use sudo to issue both of these commands:

sudo nginx -s stop

sudo chkconfig nginx off

It may be that you need to use the path:

sudo /etc/init.d/nginx stop

sudo /sbin/chkconfig nginx off

I cannot tell you this is the right path, however, this is what I found. If this does not seem to be the right path, you can always use find. You may need to use man find for specifics.
