嘗試使用的mod_proxy用的httpd和tomcat

Question

我一直在試圖用的httpd和tomcat使用的mod_proxy ...

我有VirtualBox的運行具有的httpd和Tomcat 6上的Linux科學..我做了兩個節點tomcat6中。

我遵循這個指南像10倍和斜面仍然得到Tomcat的工作的第二個節點..

http://www.richardnichols.net/2010/08/5-minute-guide-clustering-apache-tomcat/

這裏是我的http.conf文件

<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 
</Location> 

現在線這裏是我的server.xml從節點1

我不知道它是什麼。但我一直在努力了好幾天

Answer 1

這是用科學的Linux發行一個釋放6.2我不得不告訴它停止通過執行以下命令

setenforce 0

它的工作原理則阻塞端口。
