運行一段時間後Apache/mod_jk模塊無法連接jboss

Question

我使用Apache/mod_jk module來連接jboss。但經過一段時間後，出現了一些問題。

阿帕奇：2.2.22 mod_jk的：1.2.37 Jboss的：5.1.0 GA（羣集環境） OS：CentOS的5.2 x86_64的 JDK：1.6.0_30-B12

這裏是mod_jk的某些部分的.log的http.conf的

worker.loadbalancer_2.type=lb

注意事項：Jboss工作正常。 telnet jboss 8009是正常的。如果你重新啓動jboss，它會再次運行。但是，如果你重新啓動apache，它並沒有幫助。

任何人都遇到過這個問題？

Answer 1

我認爲設置連接超時ajp連接器將解決您的問題。 設置像這應該工作

<Connector port="8009" address="${jboss.bind.address}" protocol="AJP/1.3" 
     emptySessionPath="true" enableLookups="false" redirectPort="8443" maxThreads="1000" connectionTimeout="60000000" /> 

你在server.xml中，爲什麼你設置兩個相同loadbalansers配置此此屬性，你可以在官方的文檔http://docs.jboss.org/jbossweb/latest/config/ajp.html

Answer 2

您是否在server.xml文件中設置了正確的jvmRoute？

jboss-as/server/${profile}/deploy/jbossweb.sar/server.xml 

確切的行應該是這樣的：

<Engine name="jboss.web" defaultHost="localhost" jvmRoute="node1"> 

和第二臺服務器上會有=的jvmRoute 「節點2」。
