怎么样解决Oracle 11g安装中出现xhost:unable to open display的问题?

怎么样解决Oracle 11g安装中出现xhost:unable to open display的问题?

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

  [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 +
  access control disabled, clients can connect from any host
  [root@orcltest ~]#
