第三步：執行xhost +，并且提示“access control disabled, clients can connect from any host”才正確。
linux下的操作日志如下：
[root@localhost ~]# vncserverNew 'localhost:1 (root)' desktop is localhost:1Starting applications specified in /root/.vnc/xstartupLog 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
