Apache2反向代理首次安装永远加载

Question

我在整个互联网上都找遍了，但找不到任何适合我的解决方案，这让我抓狂。

我尝试使用 Tomcat8 和 Apache2 配置服务器。所以我已经安装了 Tomcat8(它正在运行)，现在我的 Apache 出现了问题(它正在运行)。

但现在我正在尝试制作一个从 apache2 到我的 Tomcat8 的反向代理。

所以我配置了这个文件:/etc/apache2/sites-available/www.bloombooking.ca.conf

<VirtualHost *:80>
       ServerName www.bloombooking.ca
       ProxyPreserveHost On
       ProxyRequests On
       ProxyPass / http://144.217.85.74/
       ProxyPassReverse / http://144.217.85.74:8080
</VirtualHost>

但是当我尝试访问我的 URL 时，它一直在加载，我收到此消息:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.

Reason: Error reading from remote server

我查看了日志，这是我得到的:

有人可以帮帮我吗？

确保在您的配置中 ProxyPass 和 ProxyPassReverse 的端口对齐

<VirtualHost *:80>
       ServerName www.bloombooking.ca
       ProxyPreserveHost On
       ProxyRequests On
       ProxyPass "/" "http://an.ip.add.res:8080/"
       ProxyPassReverse "/" "http://an.ip.add.res:8080/"
</VirtualHost>

The ProxyPass directive specifies the mapping of incoming requests to the backend server

ProxyPassReverse

To ensure that and Location: headers generated from the backend are modified to point to the reverse proxy, instead of back to itself, the ProxyPassReverse directive is most often required
