【问题描述】：
我需要在 Django 中将消息从后端推送到前端，最后我找到了这个 Twisted + Django 服务器，但在产品环境中我们使用 nginx 代理对 Django 的请求，我很困惑 hendrix 和 nginx 可以一起工作吗？
如果是，那么nginx.conf怎么写？

【问题描述】：
是的，您可以像使用任何其他 WSGI/ASGI 容器一样使用 nginx 代理传递给 hendrix。
This Question 有执行此操作的示例配置。

太好了，今天尝试使用nginx反向代理hendrix成功~

太好了，今天我尝试使用nginx反向代理hendrix成功~但是如果我想在我的产品环境中使用hendrix，我需要部署multi hendrix worker，但是我发现hendrix不支持读取从 sock 文件，当我尝试 hx start -w 4 时，我得到了错误
今天我尝试将我原来的 nginx 配置更改为反向代理 hendrix，这是一些 sn-ps：
upstream django {
server localhost:8000;
}
server {
listen 80;
server_name localhost;
location /static/ {
#root /var/www;
alias /var/www/static;
}
location / {
proxy_pass http://django;
proxy_pass_header Server;
proxy_set_header Host $host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
然后我重新启动 nginx 并启动 hendrix: hx start --log ./test.log
终于成功了，但我发现了一些警告信息： *
WebSocket 连接到“...”失败：WebSocket 期间出错 握手：“连接”标头值不是“升级”：保持活动状态 socket.io.js:2371
*
经过一些谷歌消息，我发现 nginx 版本必须更高 1.3.13，所以我将 nginx 更新到 1.10.1(stable)，警告消息消失了。
但如果想在我的生产环境中使用 hendrix，需要多个 hendrix-worker，所以我尝试：hx start -w 2，输出失败：
root@proxy:/vagrant/hendrix_taste/hendrix/examples/django_hx_chatserver/example_app# hx start -w 2
