varant 在mac上使用起來非常的方便，具體的下載步驟可以看這裡https://segmentfault.com/a/1190000000264347
這裡主要是記錄一下配置檔案
 

# -*- mode: 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|

  # 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://vagrantcloud.com/search.

  config.vm.box = "ubuntu/xenial64"                                #這裡需是預設的配置

  # 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  # `vagrant box outdated`.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.

  # NOTE: This will enable public access to the opened port

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

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

  # within the machine from a port on the host machine and only allow access

  # via 127.0.0.1 to disable public access

  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

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

  # using a specific IP.

   config.vm.network "private_network", ip: "192.168.60.60"            #這裡需要注意，配置的你是你需要訪問的ip

  # 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"    #這裡是這正常的指向就行 

config.vm.synced_folder "/Users/project/COD_ONLINE", "/var/www",create: true, owner:"www-data", group: "www-data"   #加這個是因為本的許可權一直不對，新增這個後可以直接將虛擬機器上的檔案的許可權進行改變

  # 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.

  # 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

  #   apt-get update

  #   apt-get install -y apache2

  # SHELL

end

注意1：有的時候一直出現的是 vagrant default: Warning: Connection timeout. Retrying...  被這個坑了好久，也找出了很多個不同的解決方案，終極的解決方案如下
按照https://blog.csdn.net/u011486871/article/details/79492485 裡面的操作 其中的第二條就可以解決

1、mac上的virtualbox突然提示effctive UID is not root

直接在命令列下sudo執行virtualbox是可以開啟的，但是vagrant仍然無法執行，說明還是沒有許可權

解決方法是在命令列下輸入：

for bin in VirtualBox VirtualBoxVM VBoxNetAdpCtl VBoxNetDHCP VBoxNetNAT VBoxHeadless; do
    sudo chmod u+s "/Applications/VirtualBox.app/Contents/MacOS/${bin}"
done
2、Vagrant配置network之後一直default: Warning: Remote connection disconnect. Retrying...
Vagrant init了之後，直接修改Vagrantfile檔案，將ip地址和共享目錄等配置都加上然後up

但是一旦配置network，不管是public還是private就一直響應：

    default: Warning: Connection reset. Retrying...

    default: Warning: Remote connection disconnect. Retrying...

一直不得解決

回想起剛開始跟著教程學習的時候，是一步步先up，然後再修改配置檔案，再reload

步驟如下：vagrant init -> vagrant up -> vagrant ssh -> 修改Vagrantfile -> vagrant reload

3、打包分發之後up一直提示default: Warning: Authentication failure. Retrying...

測試這個的環境是ubuntu16，按網上說的新增config.ssh.password也不行，自己生成祕鑰略麻煩，不想實驗了，以後有機會再說。

但是用centos7的景象，一切ok

另外又觀察了一下，ubuntu用原映象up提示是：

default: SSH username: ubuntu

default: SSH auth method: password

但是用box檔案生成的映象add並up後卻變成了:

default: SSH username: vagrant
default: SSH auth method: private key

而centos則始終是private key

這就是原因吧，不知道怎麼解決，這裡mark一下，作為TODO吧
