我正在尝试在同一个端口上创建一个包含多个应用程序的凤凰伞项目。使用我当前的配置，我收到此错误：

⧕ /m/i/d/p/e/portfolio on master * ⟩mix phoenix.server                                                                                                                                   13m 20s 412ms

我的伞形项目的详细信息是我目前有 3 个应用程序。1 个应用代理对其他 2 个应用的请求。代理应用程序是一个基本的插件应用程序。

# /apps/proxy/lib/proxy/plug.ex
...
  def call(conn, _opts) do
    cond do
      conn.host =~ ~r{rumbl.} ->
        Rumbl.Endpoint.call(conn, [])
      true ->
        Persona.Endpoint.call(conn, [])
    end
  end
...

角色应用

# /apps/persona/config/dev.exs
...
config :persona, Persona.Endpoint,
  http: [port: 8080],
  debug_errors: true,
  code_reloader: true,
  check_origin: false,
  watchers: [node: ["node_modules/brunch/bin/brunch", "watch", "--stdin",
                    cd: Path.expand("../", __DIR__)]]

...

Rumbl.app

# /apps/rumbl/config/dev.exs
config :rumbl, Rumbl.Endpoint,
  http: [port: 8080],
  debug_errors: true,
  code_reloader: true,
  check_origin: false,
  watchers: [node: ["node_modules/brunch/bin/brunch", "watch", "--stdin",
                    cd: Path.expand("../", __DIR__)]]

我的要求是因为我正在使用 nanabox.io 进行开发和部署，并且它要求在端口 8080 上接收所有 http/https。

如果您的代理端点无论如何都接收到所有流量，请将另外 2 个的端口设置为随机的，这样端口就不会发生冲突。
