Apache nginx连接后的phoenix websocket被拒绝

无法使用nginx之前的apache反向代理使凤凰频道在nginx之后工作

网站正常，但无法建立套接字连接。socket在dev模式下一切正常。phoenix中没有授权设置

defp authorized?(_payload) do
    true
 end

错误消息为

2017/04/29 09:40:50 [error] 10451#10451: failed (111: Connection refused) 
while connecting to upsteam, client: 192.168.0.10, 
server: somehost.com, 
request: "GET /socket/websocket?token=undefined&vsn=1.0.0 HTTP/1.1",
upstream:"http://phoenix3/socket/websocket?token=undefined&vsn=1.0.0", 
host: "somehost.com"

根据本主题的指南，这里是我提出的设置

在user_socket.ex中

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

终点

config :myapp, MyApp.Endpoint,                                               
  http: [port: {:system, "PORT"}],                                                   
  url: [host: "somehost.com", port: 80],                               
  cache_static_manifest: "priv/static/manifest.json"  

在nginx中

nbX-Real-IP或X-Cluster-Client-IP都失败

upstream phoenix3 {

 }                                                                            

在apache中（获取真实世界的连接）

ServerName somehost.com
代理主机
代理请求关闭
ProxyPass/http://192.168.0.26/                                                 
ProxyPassReverse/http://192.168.0.26/

问题在于apache配置。 nginx配置正常，phoenix配置也正常

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，然后添加一个附加的apache模块

a2enmod proxy_wstunnel
service apache2 restart

你的凤凰港是什么？8765是标准，除非您更改它。它被更改为4020，正如在topI的nginx配置中提到的，我认为apache可能正在阻止websocket连接。我试图在没有nginx的情况下直接从apache连接到phoenix，但websocket仍然无法工作。那么可能是apache配置？问题是传入的ws://somehost.com调用被原始的proxy指令转换为http://somehost.com，并且还需要它来升级与proxy\u wstunnel的连接

a2enmod proxy_wstunnel
service apache2 restart
