如下是一个示例：
原本我以为在没有联网的情况下、不能使用yum 的、可能是本地配置了yum 了吧也可以使用
1. [oracle@11GR2-test ~]$ export DISPLAY=192.168.181.128:1
在虚拟机中安装ORACLE, 设置完DISPLAY变量后,运行xhost +命令无法找到,明显为xhost相对应的rpm包未安装.
用yum命令加参数whatprovides 加xhost查到相对应的包为xorg-x11-server-utils-7.7-14.el6.x86_64,如下图.
2. [root@11GR2-test ~]# yum whatprovides */xhost
Loaded plugins: refresh-packagekit, security, ulninfo
xorg-x11-server-utils-7.7-14.el6.x86_64 : X.Org X11 X server utilities
Repo : public_ol6_latest
Matched from:
Filename : /usr/bin/xhost
3. yum安装xorg-x11-server-utils-7.7-14.el6.x86_64包
[root@11GR2-test ~]# yum install -y xorg-x11-server-utils-7.7-14.el6.x86_64
Loaded plugins: refresh-packagekit, security, ulninfo

4. 安装完xorg-x11-server-utils-7.7-14.el6.x86_64包后,产生了xhost +
[oracle@11GR2-test ~]$ xhost +
access control disabled, clients can connect from any host
多一次尝试，多一份希望 加油！
