用于本地webapp和websocket的Nginx设置

Question

following is my nginx configuration,

server { //PART-1   
        listen 80;
        server_name _;
        location / {
                proxy_pass http://127.0.0.1:8090;
                proxy_redirect off;
                proxy_pass_request_headers on;

                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;

                proxy_http_version 1.1;
                proxy_set_header Upgrade  $http_upgrade;
                proxy_set_header Connection Upgrade;
            }
        }

server { //PART-2
        listen 80;
        server_name service;
        root /usr/local/tomcat7/webapps/service-snapshot;

        location / {
                proxy_set_header X-Forwarded-Host $host;
                proxy_set_header X-Forwarded-Server $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_pass http://127.0.0.1:8080/ServiceUI/;
                }
        }

first part of config works fine for websockets, which I am already using. Second part of config is for webapp running on Apache tomcat 7.0.56, which is not working.

Is there something wrong with config? assuming server_name in both parts might be causing issue! Any suggestions!

While having multiple services on one IP and port is working perfectly fine, the server_name directive is using the HOST header submitted by the client/browser. In this case, you're not supplying the header but instead asking for a specific location on the same server (you're not asking for http://_ or http://service but for http://yourserver/services from what I see in the comments).

To make it work, you have to specify the different services via location s like this:

server { 
    listen 80;
    server_name THIS_IS_WHERE_YOUR_DOMAIN_OR_MAYBE_LOCALHOST_GOES;
    location / {
            proxy_pass http://127.0.0.1:8090;
            proxy_redirect off;
            proxy_pass_request_headers on;

            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;

            proxy_http_version 1.1;
            proxy_set_header Upgrade  $http_upgrade;
            proxy_set_header Connection Upgrade;
    }


    location /Service {

            root /usr/local/tomcat7/webapps/service-snapshot;

            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://127.0.0.1:8080/ServiceUI/;
            }
    }
