这里重点要注意的是Type的值要修改为simple,不能用原来的forking，否则会在执行systemctl start vncserver@:1.service时出现问题，故障信息如下:
[root@oracle12c system]# systemctl start vncserver@:1.service
Job for vncserver@:1.service failed. See 'systemctl status vncserver@:1.service' and 'journalctl -xn' for details.
[root@oracle12c system]# systemctl status vncserver@:1.service

3.设置远程登陆的密码
操作系统登陆，执行vncpasswd,注意这个密码不一定与操作系统登陆的密码一致，需要远程桌面的所有的账号，都需要设置一次。
[root@oracle12c /]# vncpasswd root
Password:

4.设置vncserver 为自启动
[root@oracle12c system]# systemctl daemon-reload
[root@oracle12c system]# systemctl enable vncserver@:1.service
[root@oracle12c system]# systemctl start vncserver@:1.service
[root@oracle12c system]# systemctl status vncserver@:1.service
