百胜说mod_cluster已经安装，但是文件不在那里
RHEL 6.5 + JBoss EAP 6.
我使用JBoss安装从repos安装了RHEL 6：
# yum groupinstall "JBoss EAP 6"这看起来很好，只是mod_cluster的文件并没有实际安装，尽管yum说已经安装了mod_cluster。我试过重新安装整个团队，重新安装mod_cluster，清除yum缓存等等。但是到目前为止，我感到很困惑，而且RHEL的支持还没有帮助。

我相信这是红帽的缺点。它们似乎有两个名为"mod_cluster“的包，一个包是Apache的一部分，另一个包是JBoss的一部分(它只是mod_JBoss-本机？)的别名：
mod_cluster.noarch : JBoss mod_cluster for Apache httpd
mod_cluster-demo.noarch : Sample app for mod_cluster
mod_cluster-native.x86_64 : JBoss mod_cluster for Apache httpd
mod_cluster.x86_64 : Apache HTTP load balancer"yum 'JBoss EAP 6'“应该安装mod_cluster.noarch，而不是mod_cluster.x86_64。
“'rpm -ql”的结果来自这个损坏的系统，而来自一个工作系统的结果是相同的：
# rpm -ql mod_cluster

/usr/share/maven2/poms/JPP-mod_cluster-parent.pom背景：
为在域模式下运行JBoss EAP，建立了两个RHEL6.5VM，一个系统作为域控制器/主控制器，另一个作为从控制器。这些系统运转良好。
添加了第三个VM作为第二个从机。用于安装此系统的模板与前两个模板不同。特别是，该系统使用的模板包括"epel“(Fedora)回购。另外两个越南船民没有这种回购。
在所有情况下，JBoss都按以下方式安装：
# yum groupinstall "JBoss EAP 6"这个群安装将安装软件包"mod_cluster“。epel有一个mod_cluster包(mod_cluster.x86_64)，它与JBoss EAP中的mod_cluster包(JB-EAP-6-for-heml-6-server-rpms- mod_cluster.noarch / mod_cluster-native.x86_64)相冲突。
删除epel回购解决了这个问题。在我的例子中，我重建了第三个VM，以匹配前两个VM。
