Tightvnc服务器随机崩溃？

Question

我跟着这个向导

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-20-04

但是，有时在服务器上运行状态时，我无法连接到紧密的the，我看到它不再是活动的了。

我在日记里发现

Aug 06 01:56:49 myapp1 vncserver[6198]: Log file is /home/ubuntu/.vnc/myapp1:2.log
Aug 06 01:56:49 myapp1 systemd[1]: vncserver@1.service: Can't open PID file /home/ubuntu/.vnc/myapp1:1.pid (yet?) after start: Operation not permitted

当我运行状态时，我得到：

$ sudo systemctl status vncserver@1
● vncserver@1.service - Start TightVNC server at startup
     Loaded: loaded (/etc/systemd/system/vncserver@.service; enabled; vendor preset: enabled)

重新启动紧缩服务器服务不起作用。sudo systemctl start vncserver@1

在我重新启动之后，tightvnc服务器再次正常工作。但我不想经常重启我的服务器。有什么想法吗？

我也向不同的vnc服务器开放。

编辑:我想我刚刚找到了解决方案:使用TigerVNC代替：

sudo apt purge tightvncserver
sudo apt install tigervnc-standalone-server tigervnc-viewer

这解决了我反复经历的一次坠机。

在使用此解决方案之前，至少有一种方法可以在不重新启动的情况下重新启动服务:当您运行

sudo systemctl start vncserver@1     #this fails
sudo systemctl status vncserver@1    #this shows why

您将看到它失败了，因为/tmp/.X1-lock文件仍然存在，删除该文件后，它会抱怨/tmp/.X11-unix。

所以，如果你这么做：

sudo rm -r /tmp/.X11-unix /tmp/.X1-lock
sudo systemctl start vncserver@1

您可以重新启动服务，而不需要重新启动。
