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 ~]#
