将文件从一台虚拟机传输到另一台虚拟机

Question

问题出在subconfig1.vm.provision ...上，我应该如何继续？初始化VM的Vagrant后，告诉我SSH工作正常，因为连接被拒绝。我可以完成这项工作，但只能手动插入密码，这里我最大的问题是如何超越密码来自动完成此工作流程。

# vi: set ft=ruby : 

Vagrant.configure("2") do |config| 

    config.vm.define "Machine2" do |subconfig2| 

    subconfig2.vm.box = "ubuntu/trusty64" 
    subconfig2.vm.hostname = "Machine2" 
    subconfig2.vm.network :private_network, ip: "172.16.10.101" 
    subconfig2.vm.network "forwarded_port", guest: 80, host: 4445, host_ip: "127.0.0.1" 

    end 

    #config.vm.provision "file", source: "~/.vagrant/machines/Machine2/virtualbox/private_key", destination: "/home/vagrant/ssh" 


    config.vm.define "Machine1" do |subconfig1| 
    subconfig1.vm.box = "ubuntu/trusty64" 
    subconfig1.vm.hostname = "Machine1" 
    subconfig1.vm.network :private_network, ip: "172.16.10.100" 

    # subconfig1.vm.provision "file", source: "~/.vagrant/machines/Machine2/virtualbox/private_key", destination: "/home/vagrant" 

    subconfig1.vm.provision "shell", privileged: false, inline: <<-SHELL 
     touch vagrantvm1-info 
     ifconfig | grep "HWaddr" | cut -b 32-55 >> vagrantvm1-info 
    # ssh -o StrictHostKeyChecking=no vagrant@127.0.0.1 uptime 

     cp /vagrant/.vagrant/machines/Machine2/virtualbox/private_key ~/.ssh 
     scp -P 2222 -i ~/.ssh/private_key vagrant@127.0.0.1:/home/vagrant/vagrantvm1-info /home/vagrant 

    # ssh vagrant@172.16.10.101 
    # scp vagrant@172.16.10.101:/home/vagrant/vagrantvm1-info /home/vagrant 

    SHELL 
    end 




    config.vm.provider "virtualbox" do |vb| 
# Display the VirtualBox GUI when booting the machine 
    vb.gui = true 
# Customize the amount of memory on the VM: 
    vb.memory = "1024" 
    end 

    config.vm.provision "shell", privileged: false, inline: <<-SHELL 
    apt-get install -y avahi-daemon libnss-mdns 
    apt-get update 
    apt-get install -y apache2 
    SHELL 

end

您需要传递私钥才能成功登录。

1. 检索的私钥用于

一般来说，文件是.vagrant/machines/<machine_name>/provider/private_key

下也可以运行vagrant ssh-config找出哪个私钥被用于所有的机器：

fhenri@machine:/Volumes/VM/vagrant/golang (master)$ vagrant ssh-config 
Host default 
    HostName 127.0.0.1 
    User vagrant 
    Port 2222 
    UserKnownHostsFile /dev/null 
    StrictHostKeyChecking no 
    PasswordAuthentication no 
    IdentityFile /Volumes/VM/vagrant/golang/.vagrant/machines/default/virtualbox/private_key 
    IdentitiesOnly yes 
    LogLevel FATAL 

在这种情况下，私钥是/Volumes/VM/vagrant/golang/.vagrant/machines/default/virtualbox/private_key

1. 复制VM中的密钥。

由于您要将副本虚拟机运行到虚拟机，因此原始虚拟机需要知道私钥才能连接到目标虚拟机。

使用文件配置器或shell脚本中的副本文件将用于登录到目标虚拟机的私钥复制到原始虚拟机中。

SCP使用私钥 - 见scp man page

scp -i ~/.ssh/private_key \ 
/home/vagrant/vagrantvm1-info \ 
vagrant@172.16.10.101:/home/vagrant 

更新Vagrantfile我用来测试，这是以下

# -*- mode: ruby -*- 
# vi: set ft=ruby : 

Vagrant.configure("2") do |config| 

    config.vm.define "Machine2" do |subconfig2| 

    subconfig2.vm.box = "ubuntu/trusty64" 
    subconfig2.vm.hostname = "Machine2" 
    subconfig2.vm.network :private_network, ip: "172.16.10.101" 
    subconfig2.vm.network "forwarded_port", guest: 80, host: 4445, host_ip: "127.0.0.1" 

    end 

    #config.vm.provision "file", source: "~/.vagrant/machines/Machine2/virtualbox/private_key", destination: "/home/vagrant/ssh" 


    config.vm.define "Machine1" do |subconfig1| 
    subconfig1.vm.box = "ubuntu/trusty64" 
    subconfig1.vm.hostname = "Machine1" 
    subconfig1.vm.network :private_network, ip: "172.16.10.100" 

    # subconfig1.vm.provision "file", source: "~/.vagrant/machines/Machine2/virtualbox/private_key", destination: "/home/vagrant" 

    subconfig1.vm.provision "shell", privileged: false, inline: <<-SHELL 
     touch vagrantvm1-info 
     ifconfig | grep "HWaddr" | cut -b 32-55 >> vagrantvm1-info 
    # ssh -o StrictHostKeyChecking=no vagrant@127.0.0.1 uptime 

     cp /vagrant/.vagrant/machines/Machine2/virtualbox/private_key ~/.ssh && chmod 0644 ~/.ss/private_key 
     # make sure to accept the server keys 
     ssh-keyscan 172.16.10.101 >> ~/.ssh/known_hosts 
     scp -i ~/.ssh/private_key /home/vagrant/vagrantvm1-info vagrant@172.16.10.101:/home/vagrant 

    # ssh vagrant@172.16.10.101 
    # scp vagrant@172.16.10.101:/home/vagrant/vagrantvm1-info /home/vagrant 

    SHELL 
    end 




    config.vm.provider "virtualbox" do |vb| 
# Display the VirtualBox GUI when booting the machine 
    #vb.gui = true 
# Customize the amount of memory on the VM: 
    vb.memory = "1024" 
    end 

    config.vm.provision "shell", inline: <<-SHELL 
    apt-get install -y avahi-daemon libnss-mdns 
    apt-get update 
    apt-get install -y apache2
