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 ~]# 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

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

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。
