尝试使用代理在 Apache 上运行 Faye websocket

Question

我正在尝试在瘦服务器上使用 Faye gem，在生产环境中使用 Rails，但我无法使其工作。我使用的是 apache 2.4，ws_tunnel 也启用了代理模块。我的设置如下。

Apache 配置

<VirtualHost *:443>
    ServerName mysite.example.com
    ServerAlias mysite.example.com
    DocumentRoot /var/www/html/mysite/current/public

    SSLEngine on
    SSLCertificateFile "/etc/httpd/conf/keys/ServerCertificate.cer"
    SSLCertificateKeyFile "/etc/httpd/conf/keys/example.com.key"
    SSLCertificateChainFile "/etc/httpd/conf/keys/CACertificate-1.cer"

    RewriteEngine On
    SSLProxyEngine On
    ProxyRequests off
    ProxyPreserveHost on

    ProxyPass /faye !
    ProxyPassReverse /faye !

    ProxyPass / balancer://thinservers/
    ProxyPassReverse / balancer://thinservers/
    <Proxy *>
        Require all granted
    </Proxy>

    <Location /faye>
         ProxyPass ws://localhost:9292
         ProxyPassReverse ws://localhost:9292
    </Location>

    RequestHeader set X_FORWARDED_PROTO 'https'
    # Custom log file locations
    ErrorLog  /etc/httpd/logs/error-unilever.log
    CustomLog /etc/httpd/logs/access-unilever.log combined
 </VirtualHost>

Faye.ru 文件

require 'faye'

Faye::WebSocket.load_adapter('thin')

app = Faye::RackAdapter.new(:mount => '/faye', :timeout => 25)

run app

我将使用以下命令启动 faye

rackup faye.ru -E production -s thin

这样我就可以通过在浏览器中输入以下 url 来访问 faye.js。

https://mysite.example.com/faye/faye.js

但是当我键入 https://mysite.example.com/faye/ 时，我得到以下结果

Sure you're not looking for /faye ?<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>
</head><body>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete
your request.</p>
<p>Please contact the server administrator at 
root@localhost to inform them of the time this error occurred,
and the actions you performed just before this error.</p>
<p>More information about this error may be available
in the server error log.</p>
</body></html>

这很奇怪，因为我在开发中只得到 "Sure you're not looking for /faye ?"。

我在application.js中称王菲为

client = new Faye.Client("https://mysite.example.com/faye/faye")

然后我收到类似

的错误

POST https://mysite.example.com/faye/faye 400 (Bad Request)

我还尝试在代理设置中使用 wss 协议，并将我的证书路径设置为 thin 以从 SSL 开始，但没有任何效果。

我假设这可能是由于代理或 ws_tunnel 模块而发生的，因为当我运行来自服务器 shell 的以下命令时

curl http://localhost:9292

我只收到 "Sure you're not looking for /faye ?" 条消息。

有人遇到过这样的事情吗？

如果有人能帮助我，我将不胜感激。

提前致谢。

对于遇到同样问题的朋友，我的建议是无论你使用的是哪个版本的Apache，都可以毫不犹豫的换成nginx。配置和运行非常容易。

我正在为我的应用命名示例使用以下配置。正确设置nginx后，其他一切都很好。

希望这对某人有所帮助

# app: example
# locally running on port 7000
upstream example {
    server 127.0.0.1:7000;
    server 127.0.0.1:7001;
}

# Faye is set to run on port 9292
upstream example_socket{
    server 127.0.0.1:9292;
}

server {
    # listen 80 if it's a non SSL site
    listen 443;
    server_name www.example.com;
    location /faye {
        proxy_pass http://example_socket;
        # Including common configurations
        include /etc/nginx/conf.d/proxy.conf;
        include /etc/nginx/conf.d/proxy_socket.conf;
   }

    location / {
        root /var/www/vhost/example/current/public;
        proxy_pass http://example;
        # Including common configurations
        # can be found on Internet easily
        include /etc/nginx/conf.d/proxy.conf;
    }
}
