Question

在nginx之前，也无法使用apache反向代理在nginx后面使用phoenix channel。

网站没问题，但无法建立套接字连接。套接字在开发模式下可以，一切正常。凤凰城没有授权设置

defp authorized?(_payload) do
    true
 end

错误消息

2017/04/29 09:40:50 [error] 10451#10451: failed (111: Connection refused)

按照此主题的指南进行操作是我提出的设置

在user_socket.ex

中

transport :websocket, Phoenix.Transports.WebSocket, check_origin: ["//somehost.com"]

端点

中的

config :myapp, MyApp.Endpoint,                                               
  http: [port: {:system, "PORT"}],

在nginx中

nb X-Real-IP或X-Cluster-Client-IP都失败

<VirtualHost *:80>      
  ServerName somehost.com
   ProxyPreserveHost On

   ProxyPassReverse / http://192.168.0.26/
</VirtualHost>

Answer 1

问题是apache配置。 nginx配置没问题，凤凰配置也没问题

在apache虚拟主机中，需要添加

ProxyPass /socket/ ws://192.168.0.26/socket/                                     
ProxyPassReverse /socket/ ws://192.168.0.26/socket/

在第一个块之前，然后添加一个额外的apache模块

a2enmod proxy_wstunnel
service apache2 restart

nginx连接后面的凤凰websocket拒绝了
