LAMP 專案

在此示例中，使用 Vagrant 建立自定義 LAMP 專案開發環境。

首先，你需要安裝 Virtual Box 和 Vagrant 。

然後，在主目錄中建立 vagrant 資料夾，開啟終端並將當前目錄更改為新的 vagrant 目錄。現在，執行 vagrant init。將在裡面建立一個 Vagrantfile 檔案，它將如下所示：

# -*- 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|
  # 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.
  config.vm.box = "base"

  # 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  # `vagrant box outdated`.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
end

新增或取消註釋編輯上述檔案的下一行：

config.vm.box = "hashicorp/precise64"
config.vm.network :forwarded_port, guest: 80, host: 8080
config.vm.network :private_network, ip: "192.168.33.10"
config.ssh.forward_agent = true
if Vagrant::Util::Platform.windows?
  config.vm.synced_folder "./", "/vagrant"
else
  config.vm.synced_folder "./", "/vagrant", type: "nfs"
end
# https://stefanwrobel.com/how-to-make-vagrant-performance-not-suck
config.vm.provider "virtualbox" do |v|
  host = RbConfig::CONFIG['host_os']

  # Give VM 1/4 system memory & access to all cpu cores on the host
  if host =~ /darwin/
    cpus = `sysctl -n hw.ncpu`.to_i
    # sysctl returns Bytes and we need to convert to MB
    mem = `sysctl -n hw.memsize`.to_i / 1024 / 1024 / 4
  elsif host =~ /linux/
    cpus = `nproc`.to_i
    # meminfo shows KB and we need to convert to MB
    mem = `grep 'MemTotal' /proc/meminfo | sed -e 's/MemTotal://' -e 's/ kB//'`.to_i / 1024 / 4
  else # sorry Windows folks, I can't help you
    cpus = 2
    mem = 1024
  end

  v.customize ["modifyvm", :id, "--memory", mem]
  v.customize ["modifyvm", :id, "--cpus", cpus]
end

編輯 hosts 檔案，將所需的域重定向到流浪的 VM。對於 Linux，它用作/etc/hosts，用於 Windows C:\Windows\System32\Drivers\etc\hosts; 並新增此行：

192.168.33.10 vagrantServer.com

當然，你可以用任何名稱替換 vagrantServer.com。

現在是時候建立 bootstrap.sh 檔案了（在 vagrant 目錄中）。每次從頭開始生成 VM 時，都會執行此指令碼。仔細閱讀評論：

#!/usr/bin/env bash

# .ssh/authorized_keys (you will need to create a `.ssh` directory inside the `vagrant` one and add a file named `authorized_keys` with the public keys of the users who have access to the repository and may use this environment).
# You also will have to grant access to those public keys from the Github account, Bitbucket, or whatever you're using.
cat /vagrant/config/authorized_keys >> /home/vagrant/.ssh/authorized_keys
if ! [ -d /root/.ssh ]; then
  mkdir /root/.ssh
fi
cp /vagrant/config/authorized_keys /root/.ssh
chmod 600 /root/.ssh/authorized_keys

檢查並儲存上面的檔案後，再次轉到終端，將當前目錄更改為之前建立的 vagrant，然後鍵入 vagrant up。將建立 VM，並從 VM 執行 boostrap 檔案，因此將複製/安裝所有需要的東西。完成後，你可以開啟瀏覽器轉到 vagrantServer.com（或你提供的任何名稱），你應該看到流浪漢 VM 提供的內容。

你還可以通過 vagrant/yourProjectName 目錄編輯專案檔案，並且將在主機和流浪者 VM 之間共享和同步 vagrant 目錄中的所有檔案。
