Authentication failure. Retrying - 彻底解决vagrant up时警告

碰到的问题

使用vagrant启动虚拟机时，出现如下警告：

vagrant up default: Warning: Authentication failure. retrying...

原因分析

授权失败主要原因：

虚拟机获取不到物理机的公钥（有疑问的小伙伴，建议先了解一下SSH）

解决方案

将公钥复制到虚拟机vagrant用户家目录下的authorized_keys文件中

Vagrantfile中指定物理机当前用户的私钥路径

步骤一、确认物理机中已经生成了公钥和私钥

以windows系统为例，查看当前登录用户的文件夹下是否包含.ssh文件夹，以及.ssh文件夹下是否包含id_rsa（私钥）、id_rsa.pub（公钥）两个文件

.ssh文件夹文件如下：

注意：必须打开 【显示隐藏的文件、文件夹或驱动器】才能看到.ssh文件夹

如果已经包含id_rsa（私钥）、id_rsa.pub（公钥）两个文件则可跳过步骤一。如果没有两个文件则继续往下看

生成公钥和私钥有多种方法，我们使用最常用的办法。开发者一般都会安装git。直接使用git bash生成一下就好了

一路回车，完成后，记住下面的地址

这两个文件的含是：首先，他们是1对的，两者缺1不可，id_rsa 是私钥，id_rsa.pub是公钥

步骤二、将公钥复制到authorized_keys文件中

小伙伴可能奇怪，vagrant都报错了，怎么还能进入虚拟机？没错！其实此时虚拟机已经启动完毕了，只不过此时不能接受vagrant的命令，也无法设置共享目录。

一般来说默认的用户名是vagrant，密码也是vagrant。

查看是否有authorized_keys文件

[vagrant@localhost .ssh]$ pwd

/home/vagrant/.ssh

[vagrant@localhost .ssh]$ ls -al

total 8

drwx------ 2 vagrant root 28 Jul 26 2016 .

drwx------. 8 vagrant vagrant 4096 Nov 6 11:02 ..

-rw------- 1 vagrant vagrant 786 Jul 26 2016 authorized_keys

[vagrant@localhost .ssh]$

如果authorized_keys文件不存在，则自己手动创建一下。

注意authorized_keys 文件的权限是600，所有者是vagrant，所属组也是vagrant

[vagrant@localhost .ssh]$ touch authorized_keys

[vagrant@localhost .ssh]$ chmod 600 authorized_keys

如果已经存在authorized_keys文件，复制物理机公钥文件id_rsa.pub的内容，粘贴到authorized_keys文件中。每个公钥只占一行

注意：公钥内容只占一行

例如我的authorized_keys文件中有两个公钥

[vagrant@localhost .ssh]$ vim authorized_keys

1 ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDlo4N35+9OM2UCAC82E4RtiqROZU/jI6bgg76QAA56cGdLwk4CNZzbn309nNRtO7tyBtWCyFx2AOn3Hd8hIFWiokMgxlf3eSjowT9dZqmbhGrYzAkPq r63rpHUX7M4FVjMLtoREqrGbBQZ7uZItViKeXXXl7bsGOUserLchzi+p3PJgjmw5j6ea+Kj2P7EThvcevoEPLcwGyckCTEiYo8nJ21K5bkmKCi2F8kaaJ9zbIeJ/2woayUkoZeufNo3A/gZx2bvHYAiFT 4RYLDwjrspq7pQS5Cs83YUGvolPKQfCrJRH3N+sNaeHx1NzEULMvQNxgEsFIVpi5k7OBIf4BY/ vagrant

步骤三、在物理机的Vagrantfile中添加以下内容

config.ssh.private_key_path = "C:/Users/dc/.ssh/id_rsa"

config.ssh.forward_agent = true

Vagrantfile全部配置内容如下：

# -*- mode: ruby -*-

# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure

# configures the configuration version (we support older styles for

# backwards compatibility). Please don't change it unless you know what

# you're doing.

Vagrant.configure(2) do |config|

config.vm.box = "web"

config.ssh.private_key_path = "C:/Users/dc/.ssh/id_rsa"

config.ssh.forward_agent = true

# config.winnfsd.logging="on"

# config.winnfsd.uid=1

# config.winnfsd.gid=1

# config.vm.synced_folder "./","/vagrant",type:"nfs"

config.vm.define :web do |web|

web.vm.provider "virtualbox" do |v|

v.customize ["modifyvm", :id, "--name", "web", "--memory", "2048", "--cpus","2"]

end

web.vm.box = "web"

web.vm.hostname = "web"

web.vm.synced_folder "./","/vagrant"

# web.vm.network:private_network, ip: "192.168.33.11"

web.vm.network "public_network"

end

config.vm.define :php do |php|

php.vm.provider "virtualbox" do |v|

v.customize ["modifyvm", :id, "--name", "php", "--memory", "512"]

end

php.vm.box = "php"

php.vm.network:private_network, ip: "192.168.33.10"

# php.vm.network "public_network", ip: "192.168.33.10"

php.vm.synced_folder "./","/vagrant",type:"nfs"

php.winnfsd.logging="on"

php.winnfsd.uid=1

php.winnfsd.gid=1

php.vm.synced_folder "./","/vagrant"

end

config.vm.define :swoole do |swoole|

swoole.vm.provider "virtualbox" do |v|

v.customize ["modifyvm", :id, "--name", "swoole", "--memory", "512"]

end

swoole.vm.box = "swoole"

# swoole.vm.network:private_network, ip: "192.168.33.12"

swoole.vm.network "public_network", ip: "192.168.33.12"

# swoole.vm.synced_folder "./","/vagrant",type:"nfs"

swoole.vm.synced_folder "./","/vagrant"

end

config.vm.define :master do |master|

master.vm.provider "virtualbox" do |v|

v.customize ["modifyvm", :id, "--name", "master", "--memory", "512"]

end

master.vm.box = "master"

master.vm.network "public_network"

master.vm.synced_folder "./","/vagrant"

end

config.vm.define :slave do |slave|

slave.vm.provider "virtualbox" do |v|

v.customize ["modifyvm", :id, "--name", "slave", "--memory", "512"]

end

slave.vm.box = "slave"

slave.vm.network "public_network"

slave.vm.synced_folder "./","/vagrant"

end

end

# The most common configuration options are documented and commented below.

# For a complete reference, please see the online documentation at

# https://docs.vagrantup.com.

# Every Vagrant development environment requires a box. You can search for

# boxes at https://atlas.hashicorp.com/search.

# Disable automatic box update checking. If you disable this, then

# boxes will only be checked for updates when the user runs

# `vagrant box outdated`. This is not recommended.

# config.vm.box_check_update = false

# Create a forwarded port mapping which allows access to a specific port

# within the machine from a port on the host machine. In the example below,

# accessing "localhost:8080" will access port 80 on the guest machine.

# config.vm.network "forwarded_port", guest: 80, host: 8080

# Create a private network, which allows host-only access to the machine

# using a specific IP.

# config.vm.network "private_network", ip: "192.168.33.10"

# Create a public network, which generally matched to bridged network.

# Bridged networks make the machine appear as another physical device on

# your network.

# config.vm.network "public_network"

# Share an additional folder to the guest VM. The first argument is

# the path on the host to the actual folder. The second argument is

# the path on the guest to mount the folder. And the optional third

# argument is a set of non-required options.

# config.vm.synced_folder "../data", "/vagrant_data"

# Provider-specific configuration so you can fine-tune various

# backing providers for Vagrant. These expose provider-specific options.

# Example for VirtualBox:

#

# 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

#

# View the documentation for the provider you are using for more

# information on available options.

# Define a Vagrant Push strategy for pushing to Atlas. Other push strategies

# such as FTP and Heroku are also available. See the documentation at

# https://docs.vagrantup.com/v2/push/atlas.html for more information.

# config.push.define "atlas" do |push|

# push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"

# end

# Enable provisioning with a shell script. Additional provisioners such as

# Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the

# documentation for more information about their specific syntax and use.

# config.vm.provision "shell", inline: <<-SHELL

# sudo apt-get update

# sudo apt-get install -y apache2

# SHELL

步骤四、重启虚拟机

在物理机的命令行重启虚拟机

vagrant reload XXXX
