在使用Vagrant并从脚本停止的地方开始配置计算机时，是否可以重新启动计算机? [英] Is it possible to restart a machine when provisioning a machine using Vagrant and pickup where the script left off?

问题描述

我正在bash上阅读教程，他们说要重启机器，没有选择直接重启服务的问题，这是重启机器的问题，之后还有更多命令需要在配置时运行.

I was reading a tutorial in bash where they said to restart the machine, there was no option to restart a service directly, it was a matter of restarting the machine, and then there were more commands after that that still needed to be run when provisioning.

那么，有什么方法可以在置备过程中重新启动一个盒子，然后在那之后停下来的地方继续工作吗?

So is there any way to restart a box amid provisioning and then pick up where you left off after that?

推荐答案

据我所知，如果尝试重新启动操作系统，您将无法在中断的地方执行单个脚本/命令集，例如:

As far as I know you can't have a single script/set of commands that would carry on where it left off if it attempts to restart the OS, such as:

  config.vm.provision "shell", inline: <<-SHELL
    echo $(date) > ~/rebootexample
    reboot
    echo $(date) >> ~/rebootexample
  SHELL

在此示例中，将不会执行第二次回声调用.

In this example the second echo call would not be carried out.

您可以拆分脚本/命令，并使用流浪者重装.

You could split the script/commands up and use a plugin such as vagrant reload.

Vagrantfile的示例片段，以突出显示其可能的用途:

An example snippet of a Vagrantfile to highlight its possible use:

  # execute code before reload
  config.vm.provision "shell", inline: <<-SHELL
     echo $(date) > ~/rebootexample
  SHELL

  # trigger reload
  config.vm.provision :reload

  # execute code after reload
  config.vm.provision "shell", inline: <<-SHELL
     echo $(date) >> ~/rebootexample
  SHELL
