尝试将mod_代理与httpd和tomcat一起使用

我一直在尝试将mod_代理与httpd和tomcat一起使用

我在VirtualBox上运行的是Scientific Linux，上面有httpd和tomcat 6。。我制作了两个tomcat6节点

我按照这个指南做了10次，仍然无法让tomcat的第二个节点工作

下面是我的http.conf文件中的行

<Proxy balancer://testcluster stickysession=JSESSIONID>
BalancerMember ajp://127.0.0.1:8009 min=10 max=100 route=node1 loadfactor=1
BalancerMember ajp://127.0.0.1:8109 min=10 max=100 route=node2 loadfactor=1
</Proxy>

ProxyPass /examples balancer://testcluster/examples

<Location /balancer-manager>
SetHandler balancer-manager
AuthType Basic
AuthName "Balancer Manager"
AuthUserFile "/etc/httpd/conf/.htpasswd"
Require valid-user

需要有效用户

下面是node1中的server.xml

我不知道是什么。但是我已经尝试了好几天了，这是Scientific Linux 6.2版的一个问题，我必须告诉它停止阻塞端口，方法是执行以下命令

设置强制执行0

那就行了。

在黑暗中拍摄：检查你的ipfw规则了吗？可以使用更多关于您看到的行为的信息。我做了一个服务，看起来node1工作正常。。。。我删除了node2并将node1复制到node2 dir，它成功了。。直到我将端口更改为8009以外的任何端口。我用8109进行了测试。82098019，什么都没用。。是的，我在server.xml和httpd.conf中更改了端口，直到端口工作为8009？听起来仍然像是防火墙问题。你有没有试过使用netcat（例如nc-L8009）来监听端口，看看你是否可以连接？它只在8009上工作，没有其他功能…我对8019进行了远程登录，我可以访问它
