RHEL6.4 xclock安装小记

近来要安装Oracle11G R2,操作系统为RHEL6.4，对于RHEL6.4系统没有经常使用，因为生产都用RHEL5，系统版本较为稳定，目前要安装Oracle，RHEL6.4系统已经安装完毕，系统安装都是自己依照习惯来安装rpm的软件包的依赖性的，待REHL6.4安装完毕，Oracle环境变量也都配置完成，以grid用户来运行xclock来检测图形化的安装条件时出现如下问题：

[grid@node1 ~]$ xclock
-bash: xclock: command not found

 先前以为是用户权限问题，切换至root用户还是同样问题，当时考虑是否安装xclock的rpm，通过查询确实没有安装，这里我用yum来安装软件，软件仓库提前已经配置完成，这里我就不说怎样配置YUM了，安装如下：

[root@node1 ~]# yum install xorg-x11-apps
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

待安装完成后，切换至grid用户执行xclock，我的桌面弹出了xclock的时钟，这个小问题至此解决。
