在Linux下安装Oracle时
运行
./runInstaller
报错
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
解决方法：
vncserver
root@localhost ~]# vncserver
New 'localhost:1 (root)' desktop is localhost:1
Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/localhost:1.log
export DISPLAY=localhost:1
xhost +
access control disabled, clients can connect from any host
出现上面提示即可。再次运行
./runInstaller
若是运行上述命令的时候，提示没有vncserver这个命令，则执行：
yum install tigervnc-server
若是提示没有xhost,则执行：
yum whatprovides "*/xhost" ----------------------查看是哪些提供了 */xhost

xorg-x11-server-utils-7.7-2.el6.x86_64 : X.Org X11 X server utilities ---------------------就是缺少这个包xorg-x11-server-utils-7.7-2.el6.x86_64
Repo : base
Matched from:
Filename : /usr/bin/xhost
安装xorg-x11-server-utils-7.7-2.el6.x86_64
yum -y install xorg-x11-server-utils-7.7-2.el6.x86_64
这样这两个命令就都可以用啦。
