nginx is started from npm run scripts

I had run npm run start-prod
scripts:
start-prod: has the following command

 concurrently --no-color "uwsgi --ini build/docker/uwsgi.ini" "nginx" "npm run render-prod"

npm run render-prod value for script is "render-prod": "babel-node node/react-render.jsx"

ntdl@1.0.2 start-prod /home/ubuntu/bharath/sourcecode/projects/NTDL/ntdl

Some other process is already listening on port 80. This may mean, for example, that you have an Apache process running already.

You can use this suggested command to find out what may be listening on that port:

sudo lsof -i :80 | grep LISTEN

Note: In rare cases it could be that a separate nginx is already listening on the port, for example if you manually started an nginx daemon (not recommended) or if you've modified which user nginx runs under (not recommended). More than likely, however, it'll be some other application listening on that port.

Ubuntu lets you install two web servers at once, since it's possible to configure them to listen on different ports. If you don't do this, you'll have problems with one or the other starting.
