我有一个场景，其中对 Tomcat 服务器（应用服务器）的所有请求都应通过 Apache 2.2（Web 服务器）。这两个服务器位于两台不同的机器上。出于安全原因，这两台机器不在同一个域或网络上。
我必须使用如下所示的虚拟主机设置，因为它已被我公司的其他开发人员使用过，并且经过了全面测试并且运行良好。
<VirtualHost *:*>
#Full Computer Name with port if its not 80
ServerName Full_Name_OF_Computer
ServerAlias Full_Name_OF_Computer
LogFormat "%h %l %u %t \"%r\" %s %b %D" app
CustomLog logs/app-access.log app
SSLProxyEngine On
RewriteEngine on
RewriteLogLevel 5
RewriteLog logs/rewrite.log
# Root URL handling
RewriteRule ^\/app\/?$ /app/launch.jsp [R,L]
RewriteRule ^\/app\/?$ ajp://Full_Name_OF_Computer:8009/app [P,L]
# Dynamic content
RewriteRule ^/app/(.+\.(?:jsp|do|rpc).*)$ ajp://Full_Name_OF_Computer:8009/app/$1 [P,L]
# This must be the location where application is deployed
# SHOULD THIS BE THE LOCATION WITH IN THE APPLICATION SEVER OR THE LOCATION PATH TO THE APPLICATION SERVER FROM WEB SERVER??
Alias /app "D:\apache-tomcat-7.0.63\webapps\app"

如果我在同一台机器上安装了 apache 和 tomcat 服务器，那么这对我来说没问题。但是，如果我在不同的机器上安装了 Apache 和 Tomcat 服务器（根据需要），那么我对 HTTPD.conf 进行了一些更改，之后我无法通过 Apache 访问应用程序。但是可以通过 Appplication URL 从 WebServer 访问该应用程序（使用端口 8080）。
有人可以帮我指出我做错的事情吗？
在更改 Tomcat 上的 WebServerFullName、ApplicationServerFullName 和应用程序部署文件夹的网络路径后，新的虚拟主机设置如下：
<VirtualHost *:*>
#Full Computer Name with port if its not 80
ServerName Web_Server_Ful_Name
ServerAlias Web_Server_Ful_Name
LogFormat "%h %l %u %t \"%r\" %s %b %D" app

RewriteRule ^\/app\/?$ ajp://ApplicationServerFullName:8009/app [P,L]
# Dynamic content
RewriteRule ^/app/(.+\.(?:jsp|do|rpc).*)$ ajp://ApplicationServerFullName:8009/app/$1 [P,L]
# This must be the location where application is deployed
# SHOULD THIS BE THE LOCATION WITH IN THE APPLICATION SEVER OR THE LOCATION PATH TO THE APPLICATION SERVER FROM WEB SERVER??

我对 Tomcat 上应用程序部署文件夹的网络路径有疑问，因为两台计算机不在同一个网络上，网络管理员不得不给我一个奇怪的路径，考虑到其中的美元符号 ($)，\ApplicationServerFullName\cim$\apache-tomcat-7.0.63\webapps\app （虽然可以通过浏览器从 WebServer 访问）
其他详细信息包括：
- Apache2.2
- Apache-tomcat-7.0.63-windows-x64
- Windows Server 2012 适用于 Web 服务器和应用程序服务器。
Tomcat Server.xml AJP 设置：
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

有人可以帮我解决这个问题吗，因为我没有时间实现这个功能，而且我在网上查找了很多类似的问题，但我找不到任何解决方案。
提前致谢。
答案1
该错误是由于 tomcat 的 AJP 端口无法从外部访问造成的。
打开端口后，我只是将静态内容放在 Apache 托管的服务器上，因此不需要在 WebServer 上映射网络路径。
