Apache Zeppelin背后的Apache反向代理

Question

我在Apache Web服务器后面运行我的Apache Zeppelin实例，其中Web服务器仅用作保留代理。

如果我浏览反向代理网站https://my-domain.com/zeppelin/，我会得到一个包含资产、按钮和所有内容的网站，但齐柏林飞船的websocket无法连接。浏览器开发工具将URL https://my-domain.com/zeppelin/ws称为405 HTTP method GET is not supported by this URL。

如果我直接访问齐柏林飞船网站(如http://priv.my-domain.com/zeppelin(，一切都很好。因此，这似乎不是齐柏林飞船代码中的错误，而是反向代理配置中的问题。

我的Apache反向代理配置看起来像：

<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位置，那没有什么区别。你知道吗？

编辑解决方案：在下面的答案之后，我修改了我的conf文件，它现在可以工作了！非常感谢！

        Order deny,allow
        Deny from all
        Allow from <my-ip>
    </Location>
    RewriteEngine On
    RewriteCond %{HTTP:Upgrade} =WebSocket [NC,NV]
    RewriteRule ^/(.*) ws://priv.my-domain.com:8080/$1 [P]
    <Proxy *>
        AddDefaultCharset Off
        Order deny,allow
        Allow from all
    </Proxy>
</VirtualHost>

这是我正在使用的conf，其中有些指定不一定适用于您的需求：
-mesos集群前面的服务发现
-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/$1 [P]
  RewriteCond %{LA-U:REMOTE_USER} (aaaa)
  RewriteRule ^/(.*) http://azerty01:31321/$1 [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/$1 [P]
  RewriteCond %{LA-U:REMOTE_USER} (bbbb)
  RewriteRule ^/(.*) http://azerty02:31901/$1 [P,QSA,L]
  ProxyPassReverse / http://azerty02:31901
</VirtualHost>

Answer 2

这是我在想要反向代理时创建的Includes文件齐柏林飞船服务器。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

Answer 3

我发现位置指令的顺序很重要。如果您先定义齐柏林飞船，然后定义如下所示的齐柏林飞船/ws，那么一切都会正常工作。然而，颠倒的顺序不起作用。

   <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>

除此之外，我还可以使用Apache2和下面的配置来重新路由到我的齐柏林飞船实例。重要的部分是websocket连接。

确保添加

sudo a2enmod proxy_wstunnel

然后我运行以下程序：

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/$1 [P,L]
      RewriteCond %{HTTP:Upgrade} !=websocket [NC]
     RewriteRule /(.*)           http://<Zeppelin Public IP>:8080/$1 [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，当你转到http://reverseproxypublicIP/时，它会重新路由到你的齐柏林飞船实例。希望这能帮助到别人！
