解决方法：

出现错误提示：“Xlib: connection to ":1.0" refused by server”

如下处理：

实用技巧：在Linux下设置xhost方法步骤

    第一步：用root登陆linux，启动vnc服务；

    第二步：根据vnc起来的端口，设置export DISPLAY=localhost:1（1表示vnc在第一个tty上启动的），vnc的启动信息如下：

 

[root@localhost ~]# vncserver   
  
New 'localhost:1 (root)' desktop is localhost:1  
  
Starting applications specified in /root/.vnc/xstartup   
Log file is /root/.vnc/localhost:1.log   
  
[root@localhost ~]# export DISPLAY=localhost:1    
[root@localhost ~]# xhost +   
access control disabled, clients can connect from any host  

[root@localhost ~]# vncserver

New 'localhost:1 (root)' desktop is localhost:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost:1.log

[root@localhost ~]# export DISPLAY=localhost:1
[root@localhost ~]# xhost +
access control disabled, clients can connect from any host

  

    第三步：执行xhost +，并且提示“access control disabled, clients can connect from any host”才正确。 

使用上诉方法就可以搞定。

还有个问题，在服务器在图形界面里，直接启动的Oracle页面不停的刷新，根本点不到确认按键～～    不知道问题出在哪里～～
