Question

我在Ubuntu 16.04上有一个DigitalOcean小滴，我试图为它设置远程桌面功能。我在第2步中按照这些说明进行操作。但是，当我使用VNC server命令启动vncserver时，它会变得混乱并陷入服务器直至崩溃。以下是日志文件的摘录：

这是日志的开始，它从这里进入更多混乱，有许多不同的"Cannot fork"警告。命令行中没有任何内容表示启动VNC服务器时出现问题。任何人对这里出了什么问题都有任何想法吗？

Answer 1

对于运行该过程的用户，您可能没有文件描述符。

使用ulimit -n检查当前限制是什么，并相应更改。

我怎样才能阻止vncserver在启动时崩溃？
