安装oracle数据时需要用到图形界面安装，当我们用root用户登录后切换到oracle用户时运行./runInstaller
提示报错： Can‘t connect to X11 window server using ‘:1.0‘ as the value of the DISPLAY variable.

这是因为没有赋予oracle运行图形界面的权限，这时只要在root下运行xhost + 然后回车即可解决问题。
[[email protected] ~]# xhost +
access control disabled, clients can connect from any host
[[email protected] ~]#
[[email protected] ~]# su - oracle
 再运行./runInstaller就可以出安装界面了。
