title: nginx.conf (permission to write denied). How do I fix this?
body: <p>So I am trying to follow the tutorial here: <a href="https://gorails.com/deploy/ubuntu/14.04" rel="noreferrer">https://gorails.com/deploy/ubuntu/14.04</a> to deploy a Rails app. When I tried to edit the nginx.conf at (/etc/nginx/nginx.conf) file, it tells me I have read only permission, even though I followed the steps(with setting the permissions) previously. How do I fix this? </p>
