Vagrant多虚拟机SSH无法正常工作

Vagrant多虚拟机SSH无法正常工作

3

我使用底部的Vagrantfile设置了一个多虚拟机环境。但我无法ssh进入任何一台虚拟机。我尝试了 vagrant ssh vm-cluster-node1 但它显示“未在此Vagrant环境中配置名称为'vm-cluster-node1'的虚拟机。”

如果你运行 vagrant status，你会得到什么？ - BMW

谢谢，解决了问题。Vagrant 状态给了我当前机器名称的列表，我能够正确地 ssh 连接到其中一个。如果您把这个作为答案回答，我会选择它。 - John Asbaghi

类似于config.vm.define :slave1 do |slave1|这样的代码定义了vagrant实例名称，在本例中将为slave1

因此，您需要通过vagrant ssh slave1连接到实例。

但是没有名为vm-cluster-node1的实例

为了帮助您轻松找出实例名称，请运行此命令

vagrant status
