本人需要安装vnc来登陆服务器。现在照以下这篇文章进行了安装和配置，但是运行总是报错。

运行systemctl start vncserver@:1.service报错后查status，显示:
[root@VM-0-4-centos ~]# systemctl status vncserver@:1.service
● vncserver@:1.service - Remote desktop service (VNC)

问题大概率出现在这个PID文件上，因为我的默认service文件中没有教程中的那一行“PIDFile=/home/user/.vnc/%H%i.pid“，是我手动加上的。本人基本没接触过运维，还请大家指教
