Nginx 从子域到端口的反向代理

Question

这是我的整个 nginx.conf 文件

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {
        server_name  subsonic.domain.com;
        location / {
            proxy_pass http://localhost:4040/;
            proxy_set_header Host      $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_pass_request_headers      on;
        }
    }

    # server {
    #     server_name  perforce.domain.com;
    #     location / {
    #         proxy_pass http://localhost:1666/;
    #         proxy_set_header Host      $host;
    #         proxy_set_header X-Real-IP $remote_addr;
    #         proxy_pass_request_headers      on;
    #     }        
    # }

}

我在 Windows 8 上，如果我取消注释第二个服务器声明，nginx 会立即崩溃。我花了几个小时尝试示例，但不知道为什么它不起作用。请帮忙，谢谢。
