node.js WebSockets 和 Apache 代理：如何配置 mod_proxy_wstunnel？

Question

提问by Basj

I have :

我有：

Apache(v2.4) on port 80 of my server for www.domain1.com, with mod_proxyand mod_proxy_wstunnelenabled
node.js + socket.ioon port 3001 of the same server.

Apache(v2.4) 在我的服务器的端口 80 上www.domain1.com，启用了mod_proxy和mod_proxy_wstunnel
node.js + socket.io在同一台服务器的 3001 端口上。

Accessing www.domain2.com(with port 80) redirects to 2. thanks to the method described here. I have set this in the Apache configuration:

www.domain2.com由于这里描述的方法，访问（使用端口 80）重定向到 2 。我已经在 Apache 配置中设置了这个：

<VirtualHost *:80>
    ServerName www.domain2.com
    ProxyPass / http://localhost:3001/
    ProxyPassReverse / http://localhost:3001/
    ProxyPass / ws://localhost:3001/
    ProxyPassReverse / ws://localhost:3001/
</VirtualHost>

It works for everything, except the websocket part : ws://...are not transmitted like it should by the proxy.

它适用于所有内容，除了 websocket 部分：ws://...不会像代理那样传输。

When I access the page on www.domain2.com, I have:

当我访问上的页面时www.domain2.com，我有：

Impossible to connect ws://www.domain2.com/socket.io/?EIO=3&transport=websocket&sid=n30rqg9AEqZIk5c9AABN.

Question: How to make Apache proxy the WebSockets as well?

I finally managed to do it, thanks to this topic.

多亏了这个话题，我终于做到了。

TODO:

去做：

1) Have Apache 2.4 installed (doesn't work with 2.2), and do:

1) 安装 Apache 2.4（不适用于 2.2），然后执行：

a2enmod proxy
a2enmod proxy_http
a2enmod proxy_wstunnel

2) Have nodejsrunning on port 3001

2)nodejs运行在 3001 端口

3) Do this in the Apache config

3）在Apache配置中执行此操作

<VirtualHost *:80>
  ServerName www.domain2.com

  RewriteEngine On
  RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]
  RewriteCond %{QUERY_STRING} transport=websocket    [NC]
  RewriteRule /(.*)           ws://localhost:3001/ [P,L]

  ProxyPass / http://localhost:3001/
  ProxyPassReverse / http://localhost:3001/
</VirtualHost>

Note: if you have more than one service on the same server that uses websockets, you might want to do thisto separate them.

注意：如果您在使用 websockets 的同一台服务器上有多个服务，您可能需要这样做以将它们分开。

Instead of filtering by URL, you can also filter by HTTP header. This configuration will work for any web applications that use websockets, also if they are not using socket.io:

除了按 URL 过滤，您还可以按 HTTP 标头过滤。此配置适用于任何使用 websockets 的 Web 应用程序，即使它们不使用 socket.io：

<VirtualHost *:80>
  ServerName www.domain2.com

  RewriteEngine On
  RewriteCond %{HTTP:Upgrade} =websocket [NC]
  RewriteRule /(.*)           ws://localhost:3001/ [P,L]
  RewriteCond %{HTTP:Upgrade} !=websocket [NC]
  RewriteRule /(.*)           http://localhost:3001/ [P,L]

  ProxyPassReverse / http://localhost:3001/
</VirtualHost>

May be will be useful. Just all queries send via ws to node

可能会有用。只是所有查询都通过 ws 发送到节点

<VirtualHost *:80>
  ServerName www.domain2.com

  <Location "/">
    ProxyPass "ws://localhost:3001/"
  </Location>
</VirtualHost>

As of Socket.IO 1.0 (May 2014), all connections begin with an HTTP polling request (more info here). That means that in addition to forwarding WebSocket traffic, you need to forward any transport=pollingHTTP requests.

从 Socket.IO 1.0（2014 年 5 月）开始，所有连接都以 HTTP 轮询请求开始（更多信息请点击此处）。这意味着除了转发 WebSocket 流量之外，您还需要转发任何transport=pollingHTTP 请求。

The solution below should redirect all socket traffic correctly, without redirecting any other traffic.

下面的解决方案应该正确重定向所有套接字流量，而不重定向任何其他流量。

Enable the following Apache2 mods:

sudo a2enmod proxy rewrite proxy_http proxy_wstunnel

Use these settings in your *.conf file (e.g. /etc/apache2/sites-available/mysite.com.conf). I've included comments to explain each piece:

<VirtualHost *:80>
    ServerName www.mydomain.com

    # Enable the rewrite engine
    # Requires: sudo a2enmod proxy rewrite proxy_http proxy_wstunnel
    # In the rules/conds, [NC] means case-insensitve, [P] means proxy
    RewriteEngine On

    # socket.io 1.0+ starts all connections with an HTTP polling request
    RewriteCond %{QUERY_STRING} transport=polling       [NC]
    RewriteRule /(.*)           http://localhost:3001/ [P]

    # When socket.io wants to initiate a WebSocket connection, it sends an
    # "upgrade: websocket" request that should be transferred to ws://
    RewriteCond %{HTTP:Upgrade} websocket               [NC]
    RewriteRule /(.*)           ws://localhost:3001/  [P]

    # OPTIONAL: Route all HTTP traffic at /node to port 3001
    ProxyRequests Off
    ProxyPass           /node   http://localhost:3001
    ProxyPassReverse    /node   http://localhost:3001
</VirtualHost>

I've included an extra section for routing /nodetraffic that I find handy, see herefor more info.

启用以下 Apache2 模组：

sudo a2enmod proxy rewrite proxy_http proxy_wstunnel

在您的 *.conf 文件（例如/etc/apache2/sites-available/mysite.com.conf）中使用这些设置。我已经包含注释来解释每个部分：

<VirtualHost *:80>
    ServerName www.mydomain.com

    # Enable the rewrite engine
    # Requires: sudo a2enmod proxy rewrite proxy_http proxy_wstunnel
    # In the rules/conds, [NC] means case-insensitve, [P] means proxy
    RewriteEngine On

    # socket.io 1.0+ starts all connections with an HTTP polling request
    RewriteCond %{QUERY_STRING} transport=polling       [NC]
    RewriteRule /(.*)           http://localhost:3001/ [P]

    # When socket.io wants to initiate a WebSocket connection, it sends an
    # "upgrade: websocket" request that should be transferred to ws://
    RewriteCond %{HTTP:Upgrade} websocket               [NC]
    RewriteRule /(.*)           ws://localhost:3001/  [P]

    # OPTIONAL: Route all HTTP traffic at /node to port 3001
    ProxyRequests Off
    ProxyPass           /node   http://localhost:3001
    ProxyPassReverse    /node   http://localhost:3001
</VirtualHost>

我已经包含了一个/node我觉得方便的用于路由流量的额外部分，请参阅此处了解更多信息。

For me it works after adding only one linein httpd.conf as below (bold line).

对我来说，它在 httpd.conf 中只添加一行后就可以工作了，如下所示（粗体）。


<VirtualHost *:80>
    ServerName: xxxxx

    #ProxyPassReverse is not needed
    ProxyPass /log4j ws://localhost:4711/logs
<VirtualHost *:80>

My setup:

我的设置：

Apache 2.4.10 (running off Debian)
Node.js (version 4.1.1) App running on port 3000 that accepts WebSockets at path /api/ws

Apache 2.4.10（脱离 Debian）
Node.js（版本 4.1.1）在端口 3000 上运行的应用程序在路径上接受 WebSockets /api/ws

As mentioned above by @Basj, make sure a2enmod proxy and ws_tunnel are enabled.

正如@Basj 上面提到的，确保启用了 a2enmod 代理和 ws_tunnel。

I use the same vHost config for the SSL configuration, no need to change anything proxy related.

我对 SSL 配置使用相同的 vHost 配置，无需更改任何与代理相关的内容。

For "polling" transport.

用于“轮询”传输。

Apache side:

阿帕奇方面：

<VirtualHost *:80>
    ServerName mysite.com
    DocumentRoot /my/path


    ProxyRequests Off

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass /my-connect-3001 http://127.0.0.1:3001/socket.io
    ProxyPassReverse /my-connect-3001 http://127.0.0.1:3001/socket.io   
</VirtualHost>

Client side:

客户端：

var my_socket = new io.Manager(null, {
    host: 'mysite.com',
    path: '/my-connect-3001'
    transports: ['polling'],
}).socket('/');
