Yeah @kurulumu-Net you can change port in config.json in one of the NodeBBs and change to the same port in the proxy-pass part of the corresponding nginx config.
Default port is 4567, one will need to be changed.
I am jumping the gun a bit, I haven't even set up my local dev environment yet, but I am thinking about my future deployment strategy. I am aiming to make full use of AWS, but not just using EC2 as a VPS which has the same drawbacks as any other vps system. I want the speed and reliability of the distributed system of the AWS cloud. In my personal situation, I plan to install Ghost CMS along with NodeBB and need those to be able to communicate, bonus points if you help with that.
AWS is something I am only just now starting to look into. I am setting up a local dockerfile setup for local dev at the moment, but at the moment I have no idea how to achieve the above.
Hope someone here is feeling generous!
