Apache websocket重定向到Tomcat：mod_proxy和mod_proxy_wstunnel

我想通过使用mod_proxy和mod_proxy_wstunnel模块将流量从Apache重定向到Tomcat。 HTTP流量重定向没有问题，但我无法成功重定向websocket流量与我到目前为止尝试的任何配置。Apache websocket重定向到Tomcat：mod_proxy和mod_proxy_wstunnel

我使用Apache 2.4.28和Tomcat 8.5.13

我必须说，当我使用Tomcat没有了Apache，WebSockets的工作完全正常：

Tomcat的连接器，对于工程这个配置是下一个：

<Connector URIEncoding="UTF-8" 
     compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/javascript" 
     compression="on" 
     compressionMinSize="1024" 
     connectionTimeout="20000" 
     noCompressionUserAgents="gozilla, traviata" 
     port="443" 
     protocol="org.apache.coyote.http11.Http11AprProtocol" 
     SSLEnabled="true" 
     scheme="https" 
     secure="true"> 
     <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" /> 
     <SSLHostConfig> 
      <Certificate certificateKeyFile="/opt/tomcat/cert/privkey.pem" 
         certificateFile="/opt/tomcat/cert/cert.pem" 
         certificateChainFile="/opt/tomcat/cert/chain.pem" 
         type="RSA" /> 
     </SSLHostConfig> 
    </Connector>

直到这一点很明显。现在，我在Tomcat中的前启动Apache服务器，我改的第一件事是Tomcat的连接器是这样的：

<Connector URIEncoding="UTF-8" 
    compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/javascript" 
    compression="on" 
    compressionMinSize="1024" 
    connectionTimeout="20000" 
    noCompressionUserAgents="gozilla, traviata" 
    port="8080" 
    protocol="org.apache.coyote.http11.Http11AprProtocol"> 
    <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" /> 
</Connector>

在Apache中我成功加载下一个模块（我已经确认他们真正在加载）：

LoadModule proxy_module modules/mod_proxy.so 
LoadModule proxy_http_module modules/mod_proxy_http.so 
LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so 
LoadModule ssl_module modules/mod_ssl.so

这是我在vhosts.conf文件试过的配置之一：

<VirtualHost *:443> 
    ServerName www.example.com 
    ServerAdmin [email protected] 
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined 
    CustomLog /var/log/httpd/lavnet_access.log combined 
    ErrorLog /var/log/httpd/lavnet_error.log 

    SSLProxyEngine on 
    #websocket 
    RewriteEngine on 
    RewriteCond %{HTTP:Upgrade} "(?i)websocket" 
    RewriteRule ^/(.*)$ wss://www.example.com/$1 [P] 
    #rest 
    ProxyPass "/" "http://www.example.com:8080/" 
    ProxyPassReverse "/" "http://www.example.com:8080/" 

    SSLEngine on 
    SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem 
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem 
    SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem 
</VirtualHost>

这是我已经实现最佳效果的配置，但它仍然没有工作。在lavnet_error.log日志痕迹似乎相当不错，当我尝试建立此连接：

[Tue Oct 10 16:46:39.014980 2017] [proxy:debug] [pid 10558:tid 47319680603904] proxy_util.c(2209): [client XX.XX.XX.109:11208] AH00944: connecting wss://www.example.com:443/rest/notify/675/fgcw02lm/websocket to www.example.com:443

但是，这是错误的Chrome显示：

enter image description here enter image description here

我也试过这种其他配置：

<VirtualHost *:443> 
    ServerName www.example.com 
    ServerAdmin [email protected] 
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined 
    CustomLog /var/log/httpd/lavnet_access.log combined 
    ErrorLog /var/log/httpd/lavnet_error.log 
    SSLProxyEngine on 

    ProxyPass "/rest/notify/" "wss://www.example.com:8080/rest/notify" 
    ProxyPassReverse "/rest/notify/" "wss://www.example.com:8080/rest/notify" 

    ProxyPass "/" "http://www.example.com:8080/" 
    ProxyPassReverse "/" "http://www.example.com:8080/" 

    SSLEngine on 
    SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem 
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem 
    SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem 
</VirtualHost>

但在这种情况下，我得到一个“500（内部服务器错误或）”，也我可以看到未来痕迹lavnet_error.log：

[Tue Oct 10 17:14:14.778824 2017] [proxy:warn] [pid 11924:tid 47694559057664] [client XX.XX.XXX.189:11665] AH01144: No protocol handler was valid for the URL /rest/notify/info (scheme 'wss'). If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule., referer: https://www.example.com/equipment-command-panel/8287/8482

我已经尝试了很多配置，但我不能得到这个工作。我希望你能帮助我。

谢谢。

经过多次试验，我终于解决了它。其次是万一有人工作结构需要它：

这是阿帕奇的vhost.conf文件：

<VirtualHost *:443> 
    ServerName www.example.com 
    ServerAdmin [email protected] 
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined 
    CustomLog /var/log/httpd/lavnet_access.log combined 
    ErrorLog /var/log/httpd/lavnet_error.log 

    ProxyPreserveHost On 
    ProxyPass/http://www.example.com:8080/ 
    ProxyPassReverse/http://www.example.com:8080/ 
    ProxyRequests Off 
    RewriteEngine on 
    RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC] 
    RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC] 
    RewriteRule .* ws://www.example.com:8080%{REQUEST_URI} [P] 

    SSLEngine on 
    SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem 
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem 
    SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem 
</VirtualHost>

而这一次在Tomcat的server.xml中定义的接口：

<Connector URIEncoding="UTF-8" 
    connectionTimeout="20000" 
    port="8080" 
    protocol="org.apache.coyote.http11.Http11AprProtocol"> 
    <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" /> 
</Connector>

谢谢。
