配置：

 cp /lib/systemd/system/[email protected] /etc/systemd/system/[email protected]:1.service

在這兩中把<USER>替換成root

PIDFile=/home/<USER

重啟 systemd 

systemctl daemon-reload

export DISPLAY=localhost:1

source /etc/profile

[[email protected] java]# xhost +

PORT一般為5900或者5901

遇到過的報錯：

PID file /home/root/.vnc/trs1:1.pid not readable (yet?) after start.

Host name conflict, retrying with trs1-21234

解決方法：

systemctl disable [email protected]:1

systemctl stop [email protected]:1

systemctl enable [email protected]:1

systemctl start [email protected]:1

重啟，在客戶端連線時注意加埠號
