Apache 反向代理背后的 Apache Zeppelin

Question

我运行我的 Apache Zeppelin 实例位于 Apache 网络服务器后面，网络服务器仅用作保留代理。

如果我正在浏览 reverse-proxy 站点 https://my-domain.com/zeppelin/，我会得到一个包含资产和按钮以及所有内容的网站，但 Zeppelin 的 websocket 无法连接。 Browser-Dev-Tools 对 URL https://my-domain.com/zeppelin/ws 说 405 HTTP method GET is not supported by this URL。

如果我直接进入 Zeppelin-Website (f.e. http://priv.my-domain.com/zeppelin)，一切正常。所以它似乎不是 Zeppelin-Code 中的错误，而是 reverse-proxy-config.

中的问题

我的 Apache reverse-proxy 配置如下：

<VirtualHost *:443>
    ServerName my-domain.com
    # don't loose time with IP address lookups
    HostnameLookups Off
    ProxyRequests Off
    ProxyPreserveHost Off
    SSLEngine On
    SSLProxyEngine On
    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off
    ...
    ssl cert stuff
    ...
    <Location /zeppelin/ws>

        ProxyPass ws://priv.my-domain.com:8080/zeppelin/ws
        ProxyPassReverse ws://priv.my-domain.com:8080/zeppelin/ws

        Order deny,allow
        Deny from all

        Allow from <my-ip>

    </Location>

    <Location /zeppelin/>

        ProxyPass http://priv.my-domain.com:8080/zeppelin/
        ProxyPassReverse http://priv.my-domain.com:8080/zeppelin/

        Order deny,allow
        Deny from all

        Allow from <my-ip>

    </Location>
    <Proxy *>
        AddDefaultCharset Off
        Order deny,allow
        Allow from all
    </Proxy>
</VirtualHost>

如果我从配置中删除第一个 ws-location 没有任何区别。你有什么想法吗？

编辑解决方案：在得到以下答案后，我修改了我的 conf-file，现在可以使用了！真的非常感谢！

这是我正在使用的配置文件，其中有一些不一定适用于您的需求的指定：
- 在 mesos 集群前发现服务
- 每个用户一个实例，并根据凭据

路由用户

<VirtualHost *:3128>
    <Location "/"> 
      AuthUserFile  /.............../users
      AuthName "xxxxxxxxxxxxx" 
      AuthGroupFile /dev/null 
      AuthType Basic 
      Require valid-user
    </Location> 
    ServerName xxxxxxxxxxxxxxxxxxxxxxxxxxx
    # SSLEngine on
    # SSLCertificateFile "/.............../xxxxx.crt"
    # SSLCertificateKeyFile "/.............../xxxxx.key"

  #RewriteRules for datalab with user
  RewriteCond %{HTTP:Upgrade} =WebSocket [NC,NV]
  RewriteCond %{LA-U:REMOTE_USER} (aaaa)
  RewriteRule ^/(.*) ws://azerty01:31321/ [P]
  RewriteCond %{LA-U:REMOTE_USER} (aaaa)
  RewriteRule ^/(.*) http://azerty01:31321/ [P,QSA,L]
  ProxyPassReverse / http://azerty01:31321

  #RewriteRules for datalab with user
  RewriteCond %{HTTP:Upgrade} =WebSocket [NC,NV]
  RewriteCond %{LA-U:REMOTE_USER} (bbbb)
  RewriteRule ^/(.*) ws://azerty02:31901/ [P]
  RewriteCond %{LA-U:REMOTE_USER} (bbbb)
  RewriteRule ^/(.*) http://azerty02:31901/ [P,QSA,L]
  ProxyPassReverse / http://azerty02:31901

</VirtualHost>

Answer 2

这是我想反向代理时创建的包含文件齐柏林服务器。如果愿意，您可以或多或少地将其剪切并粘贴到 vhosts conf 文件中。

#
# Apache Reverse Proxy settings for Zeppelin server.
# note:
#  Change ZEPPELING_IP_OR_HOST and ZEPPELIN_PORT as appropriate.
#
# FreeBSD put into /usr/local/etc/apache24/Includes directory,
# Linux may vary.

# This is for your-host.your-domain.com/zeppelin 
# if you want zeppelin.your-host.your-domain.com
# Put this into a vhosts file.

RequestHeader set X_FORWARDED_PROTO 'https'
ProxyPreserveHost On
RequestHeader set X-Forwarded-Port "443"
ProxyRequests     Off
ProxyVia Off
AllowEncodedSlashes NoDecode


<Location /zeppelin/ws>
    ProxyPass  ws://ZEPPELIN_IP_OR_HOST:ZEPPELIN_PORT/zeppelin/ws 
    ProxyPassReverse ws://ZEPPELIN_IP_OR_HOST:ZEPPELIN_PORT/zeppenlin/ws
</Location>

ProxyPass        /zeppelin     http://ZEPPELIN_IP_OR_HOST:ZEPPELIN_PORT/zeppelin 
ProxyPassReverse /zeppelin     http://ZEPPELIN_IP_OR_HOST:ZEPPELIN_PORT/zeppelin

补充一下，我能够使用 Apache2 和下面的配置来重新路由到我的 zeppelin 实例。重要的部分是 websocket 连接。

确保添加

sudo a2enmod proxy_wstunnel

到模组。然后我运行以下内容：

sudo a2dissite 000-default
sudo nano /etc/apache2/sites-available/proxy-host.conf
    # Insert the following into the proxy-host.conf file
    <VirtualHost *:80>
      ServerName '<Zeppelin Public IP>:8080'
      RewriteEngine On
      RewriteCond %{HTTP:Upgrade} =websocket [NC]
      RewriteRule /(.*)           ws://<Zeppelin Public IP>:8080/ [P,L]
      RewriteCond %{HTTP:Upgrade} !=websocket [NC]
     RewriteRule /(.*)           http://<Zeppelin Public IP>:8080/ [P,L]
     ProxyPassReverse / http://<Zeppelin Public IP>:8080/
    </VirtualHost>
    # / text insert
sudo a2ensite proxy-host
sudo nano /etc/apache2/ports.conf
   #Add this to the ports.conf file and cntrl+X to save & exit  
   Listen 8080
sudo /etc/init.d/apache2 restart

然后当您转到 http://reverseproxypublicIP/ 时，它会重新路由到您的 Zeppelin 实例。希望这对某人有所帮助！

我发现位置指令的顺序很重要。如果您首先定义齐柏林飞艇然后 zeppelin/ws 如下所示，那么一切正常。但是，相反的顺序不起作用。

   <Location /zeppelin/>
        ProxyPass http://priv.my-domain.com:8080/zeppelin/
        ProxyPassReverse http://priv.my-domain.com:8080/zeppelin/
    </Location>
    <Location /zeppelin/ws>
        ProxyPass ws://priv.my-domain.com:8080/zeppelin/ws
        ProxyPassReverse ws://priv.my-domain.com:8080/zeppelin/ws
    </Location>
