这篇文章主要给大家介绍了关于在ORACLE 11g安装中出现xhost: unable to open display问题的解决方法，文中介绍的非常详细，对大家具有一定的参考价值，需要的朋友们下面来一起看看吧。

一、Xhosts报错

安装好vncserver，本地pc笔记本能通过vnc viewer远程连接Oracle服务器，但是在执行xhost+报错，尝试过localhost，尝试过127.0.0.1，也试过本机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、去查看后台的vnc日志信息，日志信息，看到vnc日志信息正常，没有啥异常信息

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

三、试试xdyinfo

Google到了一些资料，有准备安装xdyinfo成功的，这里也试试看，先安装xdpyinfo

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

   Complete!
   [root@orcltest ~]#

之后再执行xdpyinfo，可以xhsot +成功，如下所示，就可以启动./runInstaller安装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 ~]#
