node.js - Nginx 在 80 端口设置 nodejs

Question

我想将 nodejs 绑定(bind)到一个 url，就像这样: http://myproject.com/nodejs/

目前，我的 Node 在8080端口。

我有 nginx 配置:

upstream app {
    server 127.0.0.1:8080;
}    
server {
    listen   80; ## listen for ipv4; this line is default and implied

    root /home/myproject/www;
    index index.html index.htm;

    server_name myproject.com;

            location /nodejs/ {
                  proxy_set_header X-Real-IP $remote_addr;
                  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                  proxy_set_header Host $http_host;
                  proxy_set_header X-NginX-Proxy true;

                  proxy_pass http://app/;
                  proxy_redirect off;
            }
}

当我打开 url 时，我得到:

Welcome to socket.io.

连接正常

但是，当我尝试连接到我的网站时，我得到了这个:

GET http://myproject.com/socket.io/1/?t=1385767934694 404 (Not Found) socket.io.js:1659

这是我用于连接的网站行:

    var socket = io.connect('http://myproject.com/nodejs/');

我该怎么做？

Answer 1

我得到一个错误 =/

WebSocket connection to 'ws://myproject/socket.io/1/websocket/IomP5jiBBNv8rgGYFFUS' failed: Error during WebSocket handshake: 'Connection' header value is not 'Upgrade'

这是我的 nginx 服务器端配置:

map $http_upgrade $connection_upgrade {
    default   upgrade;
    ''        close;
}

server {
    listen   80; ## listen for ipv4; this line is default and implied

    root /home/myproject/www;
    index index.html index.htm;

    server_name myproject.com;

        location /socket.io/ {
        proxy_pass http://localhost:8080;
        proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
        }
}

如果我不添加:

    map $http_upgrade $connection_upgrade {
    default   upgrade;
    ''        close;
}

我收到这个错误:

Restarting nginx: nginx: [emerg] unknown "connection_upgrade" variable
nginx: configuration file /etc/nginx/nginx.conf test failed
