帮助使用 mod_jk 转发到后端应用程序服务器
我之前有 mod-jk 可以工作，但是在切换服务器并修改一些文件后，它不再工作。我使用 mod_jk-1.2.28 和 JBoss 4.2.3 作为后端。
在 JBoss server.xml 文件中，我在端口 8009 上定义了 AJP 1.3 连接器，并将 jboss 绑定到服务器的新 IP 地址。我尝试转发到的应用程序部署为：
[TomcatDeployer] deploy, ctxPath=/ManualAlerts, warUrl=.../tmp/deploy/tmp8097651929280250028ManualAlertsApp.ear-contents/ManualAlerts-exp.war/
在Web服务器上，我有worker.properties，其中包含为JBoss地址和端口8009设置的worker。mod
-jk.conf有JkMount /ManualAlerts/*worker1。
难道这不应该将所有对 URL http://address/ManualAlerts/ 的 Web 服务器请求转发到后端吗应用程序名为 ManualAlerts？
mod-jk.log 显示：

在应用程序服务器上运行 netstat -an 显示 jboss 正在侦听 8009，并且本地地址是应用程序服务器的地址。在 mod-jk.log 中，它显示连接到 (XXX.XXX.XXX.XXX:8009) 失败，并且应用程序服务器地址在这里也是正确的。我无法弄清楚是什么导致了这个问题。
I had mod-jk working a while ago but after switching servers and modifying some files, it no longer works. I am using mod_jk-1.2.28 with JBoss 4.2.3 as the backend.
In the JBoss server.xml file I have the AJP 1.3 connector defined on port 8009 and I am binding jboss to the server's new IP address. The app I am trying to forward to is deployed as:
[TomcatDeployer] deploy, ctxPath=/ManualAlerts, warUrl=.../tmp/deploy/tmp8097651929280250028ManualAlertsApp.ear-contents/ManualAlerts-exp.war/
On the web server, I have worker.properties with a worker set for the JBoss address and port 8009.
The mod-jk.conf has JkMount /ManualAlerts/* worker1.
Shouldn't this forward all requests to the web server with the URL http://address/ManualAlerts/ to the backend app named ManualAlerts?
The mod-jk.log shows:
[Sat Oct 31 14:19:28 2009][30709:3086014224] [error] ajp_send_request::jk_ajp_common.c (1507): (worker1) connecting to backend failed. Tomcat is probably not started or is listening on the wrong port (errno=115)

Running netstat -an on the app server shows jboss listening on 8009 and the local address is the app server's address. In the mod-jk.log it shows connect to (XXX.XXX.XXX.XXX:8009) failed, and the app-server address is correct here, too. I cannot figure out what's causing the issue.

最好发布您的 mod-jk.conf、workers.properties 和 ajp 连接定义。如果没有它们，我建议您应该尝试添加以下安装点：
It msay be s good idea to post your mod-jk.conf, workers.properties and the ajp connection definition. Without them, I'd say you should try adding the following mount point:
