1,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"

 

 

 

2,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

3,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 +

         access control disabled, clients can connect from any host

         [root@orcltest ~]#
