[oracle@localhost database]$ ./runInstaller

执行如下命令得以解决，而不是很多人说的export DISPLAY=localhost:0.0, 不知道为什么这样，有谁知道告诉我，[email protected] ,非常感谢

[oracle@localhost database]$ export DISPLAY=:0
[oracle@localhost database]$ su
Password:
[root@localhost database]# xhost + localhost
localhost being added to access control list

 

PS: xhost + hostname /IP : 指定的host就可以让Client端能使用当前服务器的X Server，即用服务器的显示设备做为终端来输出。
