我们直截了当直截了当说出解决办法
安装tigervnc-server
在终端运行vncserver
输出如下内容
You will require a password to access your desktops.
Password:
Verify:
Would you like to enter a view-only password (y/n)? y
Password:
Verify:
xauth: file /root/.Xauthority does not exist
New 'db.zyxasr.com:1 (root)' desktop is db.zyxasr.com:1
Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/db.zyxasr.com:1.log
这个时候再次执行xhost + 依然报错
在vncserver输出的结果中，我们可以看出 是在终端1上有界面显示 [db.zyxasr.com:1]
所以这是导入环境变量export DISPLAY=localhost:1
再次执行xhost +
输出access control disabled, clients can connect from any host
这样就完成了
