Authentication failure. Retrying - 徹底解決vagrant up時警告

碰到的問題

使用vagrant啟動虛擬機時，出現如下警告：

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

原因分析

授權失敗主要原因：

虛擬機獲取不到物理機的公鑰（有疑問的小伙伴，建議先了解一下SSH）

解決方案

將公鑰復制到虛擬機vagrant用戶家目錄下的authorized_keys文件中

Vagrantfile中指定物理機當前用戶的私鑰路徑

步驟一、確認物理機中已經生成了公鑰和私鑰

以windows系統為例，查看當前登錄用戶的文件夾下是否包含.ssh文件夾，以及.ssh文件夾下是否包含id_rsa（私鑰）、id_rsa.pub（公鑰）兩個文件

.ssh文件夾文件如下：

注意：必須打開 【顯示隱藏的文件、文件夾或驅動器】才能看到.ssh文件夾

如果已經包含id_rsa（私鑰）、id_rsa.pub（公鑰）兩個文件則可跳過步驟一。如果沒有兩個文件則繼續往下看

生成公鑰和私鑰有多種方法，我們使用最常用的辦法。開發者一般都會安裝git。直接使用git bash生成一下就好了

一路回車，完成后，記住下面的地址

這兩個文件的含是：首先，他們是1對的，兩者缺1不可，id_rsa 是私鑰，id_rsa.pub是公鑰

步驟二、將公鑰復制到authorized_keys文件中

小伙伴可能奇怪，vagrant都報錯了，怎么還能進入虛擬機？沒錯！其實此時虛擬機已經啟動完畢了，只不過此時不能接受vagrant的命令，也無法設置共享目錄。

一般來說默認的用戶名是vagrant，密碼也是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，則自己手動創建一下。

注意authorized_keys 文件的權限是600，所有者是vagrant，所屬組也是vagrant

[vagrant@localhost .ssh]$ touch authorized_keys

[vagrant@localhost .ssh]$ chmod 600 authorized_keys

如果已經存在authorized_keys文件，復制物理機公鑰文件id_rsa.pub的內容，粘貼到authorized_keys文件中。每個公鑰只占一行

注意：公鑰內容只占一行

例如我的authorized_keys文件中有兩個公鑰

[vagrant@localhost .ssh]$ vim authorized_keys

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

步驟三、在物理機的Vagrantfile中添加以下內容

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

config.ssh.forward_agent = true

Vagrantfile全部配置內容如下：

# -*- 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

步驟四、重啟虛擬機

在物理機的命令行重啟虛擬機

vagrant?reload XXXX
