Nginx subdomain vhost [SOLVED]

[Praveen]

Hello
I am having trouble setting up the following configuration.

domain.com - nginx (reverse proxy) -> Apache ---- This works, no issues
myapp.domain.com - nginx (reverse proxy) -> Nodejs ---- This setup doesn't work.

Here are the things which I tried.

My app works as subfolder (by adding "location /myapp" and proxy directives in Plesk web server settings -> nginx directives )
domain.com/myapp - nginx (reverse proxy) -> Nodejs --- works

But I want it at the subdomain root level. So I created a subdomain in plesk and I tried the "location /" in nginx directive, but I am getting duplicate location.

So I deleted the subdomain and tried the server directive in /etc/nginx/conf.d/myapp.conf as follows,

server {
        listen 0.0.0.0:80;
        server_name myapp.domain.com;
        access_log /var/log/nginx/myapp.log;
        location / {
            proxy_pass http://127.0.0.1:38600/;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-NginX-Proxy true;
            proxy_cache_bypass $http_upgrade;
        }
}

What I am getting is plesk default web page and not my app page. My subdomain DNS is also setup to point to main domain's ip address.

So how do I achieve this setup? Please help.

Hi Praveen,

without any specific root - folder definition, you always will be rooted to for example "/var/www/vhosts/default/htdocs". Please have a look at your default site - configuration, defined at "/etc/nginx/sites-enabled/*" to learn how your system is configured.

 

[Praveen]

Thanks for the feedback. My nginx installation does not contain sites-enabled folder but it contains conf.d, so I added my subdomain conf in that folder as shown in the original post. Moreover is the root definition required? Because nginx has to just proxy the request (on a subdomain) to nodejs running on specific port in localhost.

I also tested with root set to my nodejs app folder but still getting the default domain page.

 

[Praveen]

I got it to work. This line was causing the problem

access_log /var/log/nginx/myapp.log;

I missed double quotes for the path.

 

[Praveen]

Again the problem started showing up. I don't know what is causing the issue. Double quotes/no quotes does not make any difference.

Hi Praveen,

apache and nginx have both "configuration checker" included. Before you restart apache and/or nginx ( because you probably added configuration directives or modifications ), please always use the commands:

/usr/sbin/apachectl -t
Successfull configuration checks end with "Syntax OK"​

or/and

/etc/init.d/nginx configtest
Successfull configuration checks end with:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

Looks like 0.0.0.0 is not working whereas when I give the specific ip, it is working.
