nginx请求后关闭上游连接 [英] nginx close upstream connection after request

问题描述

我需要保持nginx和上游nodejs之间的连接。

I need to keep alive my connection between nginx and upstream nodejs.

刚刚编译并安装了nginx 1.2.0

Just compiled and installed nginx 1.2.0

我的配置文件：

upstream backend {
    ip_hash;
    server dev:3001;
    server dev:3002;
    server dev:3003;
    server dev:3004;
    keepalive 128;
}

server {
    listen      9000;
    server_name dev;

    location / {
        proxy_pass http://backend;
        error_page  404 = 404.png;
    }
}

我的程序（开发：3001 - 3004）检测到响应后，nginx关闭了连接。

My programe (dev:3001 - 3004) detect that the connection was closed by nginx after response.

文档指出对于http keepalive，你还应该设置 proxy_http_version 1.1; 和 proxy_set_header连接;

The documentation states that for http keepalive, you should also set proxy_http_version 1.1; and proxy_set_header Connection "";
