Question

我使用Apache/mod_jk module连接jboss。但是经过一段时间后，出了点问题。

Apache：2.2.22 mod_jk：1.2.37 Jboss：5.1.0 GA（集群环境）操作系统：CentOS 5.2 x86_64 JDK：1.6.0_30-b12

以下是mod_jk.log的一部分

http.conf的一部分：

JkWorkersFile conf/workers.properties

JkLogFile logs/mod_jk.log
JkLogLevel warn

workers.properties：

 worker.list=loadbalancer,loadbalancer_2,status
 worker.node1.port=8009
 worker.node1.host=10.123.76.6
 worker.node1.type=ajp13
 worker.node1.lbfactor=1

 worker.node2.port=8009
 worker.node2.host=10.123.76.4
 worker.node2.type=ajp13
 worker.node2.lbfactor=1

 worker.loadbalancer.type=lb
 worker.loadbalancer.balance_workers=node1,node2

 worker.loadbalancer.sticky_session=true
 worker.loadbalancer.sticky_session_force=false

 worker.loadbalancer_2.type=lb
 worker.loadbalancer_2.balance_workers=node1,node2
 worker.loadbalancer_2.sticky_session=true
 worker.loadbalancer_2.sticky_session_force=false

注意事项：Jboss工作正常。 telnet jboss 8009是正常的。如果你重新启动jboss，它会再次运行。但是，如果你重新启动apache，它就无济于事。

有人遇到过这个问题吗？

Answer 1

我认为设置ajp连接器的连接超时可以解决您的问题。像这样的设置应该有效

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

您在server.xml中配置它

有关此属性的更多文档，您可以在官方文档http://docs.jboss.org/jbossweb/latest/config/ajp.html

中阅读

Answer 2

您是否在server.xml文件中设置了正确的jvmRoute？

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

确切的行应如下所示：

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

并且在第二台服务器上将有jvmRoute =“node2”。

Answer 3

请按以下步骤解决问题。 1.在不重新启动Web服务器的情况下，从其他浏览器中单击URL。（如果其不起作用，下面的解决方案将为您工作）

请检查两个JBoss配置必须启用8009（AJP）端口。在您的情况下，两个不同的物理服务器中有两个实例。必须配置上述端口。它是默认设置。检查是否被错误更改。基本上，这对应于http偏移量0。

运行一段时间后，Apache / mod_jk模块无法连接jboss
