Question

Vestacp Nginx proxy passing to a node application

Hello DO Community, I hope all of you are doing great.

I am facing an issue with nginx proxy passing. So far I have successfully install Ubuntu 14.04 and vestacp panel and they are working great. I can even create sub-domains with no problem.

Now I want to create a ghost blog in a sub-domain (eg blog.main-doimain.com) which by the way runs on node. I have managed to run the ghost blog on port 3000 and i can access it using main-domain.com:3000

To access it via sub-domain I have added following server block on nginx (which is installed by vestacp)

server {
    listen 80;
    server_name blog.main-domain.com;

    root /var/www/ghost;
    index index.html index.htm;

    location / {
        proxy_pass http://127.0.0.1:3000;
    }
}

but still i can’t access it.

Then I created a blank droplet, installed ubuntu 14.04, installed nginx (only) then installed ghost in it in the same way and added the above server block. And surprisingly it worked, I could access it like blog.main-domain.com!!!

My question is:

  1. Am I doing something wrong??
  2. Does vestacp & ghost work along side this way or not??
  3. Has anyone tried something like this and succeeded or failed??

Thank you and sorry for really long post.

I was able to solve my problem. I had to make following changes to do so:

in the server block:

    server {
        # previously
        # listen 80; 

        # now
        # here a.b.c.d is my droplet ip
        listen a.b.c.d:80;  

        server_name blog.main-domain.com;

        root /var/www/ghost;
        index index.html index.htm;

        location / {
            # previously
            # proxy_pass http://127.0.0.1:3000;

            # now
            # here a.b.c.d is my droplet ip
            proxy_pass http://a.b.c.d:3000;
        }
    }

and in the ghost blog config file:

    server: {
        host: 'a.b.c.d', /* here a.b.c.d is my droplet ip */
        port: '3000'
    }

and lastly i had to change iptable to accept request on port 3000. that it!

When i do that my mail service stop working, what should i do??

ip i try to redirect x.x.x.x:8069, i want to show like x.x.x.x

when i try to loging to my x.x.x.x/webmail i get 404
