楼主不知道怎么回事，突然就边不上VNC了，我就打算重新启动服务，发现服务启不来，我用
journalctl -xe命令出现下面的东西：

然后我知道可能是
于是我就把这个文件删除，再重启 发现就好啦
[root@zhouziqi tmp]# rm -rvf .X11-unix
removed ‘.X11-unix/X0’
removed ‘.X11-unix/X1’
removed directory: ‘.X11-unix’
[root@zhouziqi tmp]# systemctl restart vncserver@:1.service
[root@zhouziqi tmp]#
楼主想看看这个文件夹是干嘛的，我就进去看看，原来这个文件夹是里面是一个文件，X1，估计这个文件是你连接的时候产生的，如果你VNC不正常退出的话，这个文件就没有被删除，所以就会出现
A VNC server is already running as :1，这时候你只要手动删除那个文件夹里面的文件就可以重启服务啦
