route different proxy based on subdomain request in nginx

Question

I have one dedicated server in that server I deployed 5 nodejs application.

domain name: www.nnd.com dedicated server ip: xxx.xx.x.60 

I had domain which is pointed to my dedicated server ip.

sub domains are :

app1.nnd.com pointed to xxx.xx.x.60 app2.nnd.com pointed to xxx.xx.x.60 app3.nnd.com pointed to xxx.xx.x.60 app4.nnd.com pointed to xxx.xx.x.60 app5.nnd.com pointed to xxx.xx.x.60 

now in nginx configuration file based on the subdomain I need to route proxy. Example:

{     listen:80;     server_name:xxx.xx.x.60     location / {         #here based on subdomain of the request I need to create proxy_pass for my node application      } } 

Is there any condition and how can I get the original domain name from proxy header?

Answer 1

create a virtual host for each

server {   server_name sub1.example.com;   location / {     proxy_pass http://127.0.0.1:xxxx;   } } server {   server_name sub2.example.com;   location / {     proxy_pass http://127.0.0.1:xxxx;   } } 

And go on, change the port number to match the right port.
