這篇文章主要給大家介紹了關(guān)于在ORACLE 11g安裝中出現(xiàn)xhost: unable to open display問題的解決方法，文中介紹的非常詳細，對大家具有一定的參考價值，需要的朋友們下面來一起看看吧。

一、Xhosts報錯

安裝好vncserver，本地pc筆記本能通過vnc viewer遠程連接Oracle服務(wù)器，但是在執(zhí)行xhost+報錯，嘗試過localhost，嘗試過127.0.0.1，也試過本機ip地址，都是unable toopen displa，如下所示

[root@orcltest ~]# export DISPLAY=localhost:1
[root@orcltest ~]# xhost
xhost: unable to open display "localhost:1"
[root@orcltest ~]#
 
[root@orcltest ~]# export DISPLAY=127.0.0.1:1
[root@orcltest ~]# xhost
xhost: unable to open display "127.0.0.1:1"
[root@orcltest ~]# xhost +
xhost: unable to open display "127.0.0.1:1"
[root@orcltest ~]# xhost + 192.51.3.12
xhost: unable to open display "192.51.3.12:1"

二、去查看后臺的vnc日志信息，日志信息，看到vnc日志信息正常，沒有啥異常信息

   [root@orcltest ~]# vim /root/.vnc/orcltest:1.log

三、試試xdyinfo

Google到了一些資料，有準備安裝xdyinfo成功的，這里也試試看，先安裝xdpyinfo

   [root@orcltest ~]# xdpyinfo
   -bash: xdpyinfo: command not found
   [root@orcltest ~]# yum install -y xdpyinfo
   Loaded plugins: refresh-packagekit, security

   Complete!
   [root@orcltest ~]#

之后再執(zhí)行xdpyinfo，可以xhsot +成功，如下所示，就可以啟動./runInstaller安裝oracle了。

   [root@orcltest ~]# xdpyinfo
   xdpyinfo: unable to open display "localhost:1".
   [root@orcltest ~]# xhost + 192.51.3.12
   Xhost: unable to open display "localhost:1"
   [root@orcltest ~]# export DISPLAY=:1.0 
   [root@orcltest ~]# xhost +

   [root@orcltest ~]#
