我在RedHat上做Jboss集群（JDK 1.5.0.12，Jboss 4.0.5 GA，apache 2.2.4，apache mod_jk 1.2.23），有三台机器192.168.1.78（Jboss节点,节点名为： Node2,端口:8888）,192.168.1.79(Jboss节点，节点名为：Node1,端口:8888)，192.168.1.80（Apache服务器,端口:8080）,现在各节点均启动成功，并且:http://192.168.1.(78/79):8888均成功出现Jboss的欢迎界面，Apache服务启动也成功，用netstat命令查看，有8080监听端口存在，但是输入:http://192.168.1.80:8080出现如下503错误：Service Temporarily Unavailable !

看看是不是selinux关掉了。

selinux有时候会影响系统服务的正常使用。
getenforce命令查看当前selinux状态
setenforce 0命令设置暂时无效
彻底无效修改/etc/sysconfig/selinux文件
SELINUX=enforcing
改成
SELINUX=disabled
getenforce命令查看当前selinux状态
setenforce 0命令设置暂时无效
彻底无效修改/etc/sysconfig/selinux文件
SELINUX=enforcing
改成
SELINUX=disabled
