linux都有哪些运行级别？

答: 一共有七种运行级别,如下:

  • 0 – System halt i.e the system can be safely powered off with no activity.
  • 1 – Single user mode.
  • 2 – Multiple user mode with no NFS(network file system).
  • 3 – Multiple user mode under the command line interface and not under the graphical user interface.
  • 4 – User-definable.
  • 5 – Multiple user mode under GUI (graphical user interface) and this is the standard runlevel for most of the LINUX based systems.
  • 6 – Reboot which is used to restart the system
