執行如下命令得以解決，而不是很多人說的export DISPLAY=localhost:0.0, 不知道爲什麼這樣，有誰知道告訴我，[email protected] ,非常感謝
[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就可以讓Client端能使用當前服務器的X Server，即用服務器的顯示設備做爲終端來輸出。
