我使用Apache/mod_jk 模块来连接 jboss。但是运行一段时间后,出现了问题。

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

这是 mod_jk.log 的一部分

注意:Jboss 工作正常。 telnetjboss8009是正常的。如果你重新启动 jboss,它会再次工作。但是如果你重启apache就没有用了。</p>

有人遇到过这个问题吗?

我认为为 ajp 连接器设置连接超时可以解决您的问题。这样的设置应该可以

<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

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

确切的行应该是这样的:

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

在第二台服务器上会有 jvmRoute="node2"。

请按照以下方式解决问题。1.从不同的浏览器点击URL而不重新启动网络服务器。(如果它不工作下面的解决方案将适用于你)

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。检查是否误改。基本上这对应于 http 偏移量 0。
