Vagrant基础简要记录

della0887

　　Vagrant是一种开源软件，它为跨众多操作系统构建可重复的开发环境提供了一种方法。Vagrant使用提供者(provider)来启动隔离的虚拟环境。默认的提供者是Virtualbox
　　Vagrant ( http://www.vagrantup.com/ ) is a powerful development tool, which
　　lets you manage and support the virtualization of your development environment.
　　Instead of running all your projects locally on your own computer, having to juggle
　　the different requirements and dependencies of each project, Vagrant lets you run
　　each project in its own dedicated virtual environment.
　　Vagrant uses Providers to integrate with the third-party virtualization software,
　　which provides the virtualized machines for our development environment. The
　　default provider is for Oracle's VirtualBox however, there are providers to work
　　with Amazon Web Services and VMware Fusion. The entire configuration is stored
　　in simple plain text files. The Vagrant configuration (Vagrantfile), Puppet, and Chef
　　manifests are simply written in text files in a Ruby Domain Specific Language. This
　　means we can easily share the configurations and projects with colleagues, using
　　Version Control Systems such as Git or Subversion.
Docker vs Vagrant

　　vagrant可以帮助用户管理/部署虚拟机的程序。docker是一个帮助用户创建/运行/管理基于lxc的linux container的程序。coreos是一个专门为运行linux container而设计的发行版。
安装和使用

　　https://docs.vagrantup.com/v2/providers/ VMWare和Virtualbox等各种提供者
　　Vagrant can be installed on Linux, Windows, and Mac OS X, and although it
　　uses Ruby, the package includes an embedded Ruby interpreter. The only other
　　requirement is a virtualization tool such as Oracle's VirtualBox. The Oracle's
　　VirtualBox provider is available for free, and is included built-in with Vagrant
　　https://www.virtualbox.org/
　　http://downloads.vagrantup.com
　　Each virtual machine starts with what Vagrant calls a base box. This is a specially
　　packaged version of an operating system with some specific configurations in
　　place. The number of configurations and packages installed on this packaged
　　operating system is typically minimal (containing only a few tools which allow it
　　to communicate with Vagrant).
初始化
　　Ubuntu的几个box
　　Ubuntu10
　　·  Lucid32 is available at  http://files.vagrantup.com/lucid32.box
　　·  Lucid64 is available at  http://files.vagrantup.com/lucid64.box
　　Ubuntu12
　　·  Precise32 is available at  http://files.vagrantup.com/precise32.box
　　·  Precise64 is available at  http://files.vagrantup.com/precise64.box
　　Ubutnu14
　　vagrant init ubuntu/trusty64; vagrant up --provider virtualbox
　　vagrant init precise64 http://files.vagrantup.com/precise64.box
　　Vagrantfile生成[ruby]
　　vagrant init base64
　　vagrant init
　　vagrant box add <name> <url> [--provider provider] [--force]
Powering up
　　vagrant up
　　Vagrant will then perform the following:
　　·  Copy the base box
　　·  Create a new virtual machine with the relevant provider (the default
　　being VirtualBox)
　　·  Forward any configured ports; by default, it will forward port 22 (SSH) on
　　the VM to port 2222 on the host; this will allow us to connect to the VM
　　·  Boot (power up) the VM
　　·  Configure and enable networking, so that we can communicate with the VM
　　·  Map shared folders between the host and the guest (by default, it will map
　　the folder containing the Vagrant project to  /vagrant on the guest machine)
　　·  Run any provisioning tools that are set up such as Puppet, Chef, or
　　SSH provisioning
　　vagrant suspend
　　vagrant resume
　　vagrant halt
　　vagrant destroy
　　vagrant ssh
和HOST机器共享
　　Port forwarding
　　Vagrantfile 文件中进行端口映射
　　config.vm.network :forwarded_port, guest: 80, host: 8888
　　Synced folders
　　config.vm.synced_folder "/Users/michael/assets/" "/var/www/assets"
　　The first parameter is the path to the folder on our machine, the second being the
　　mount point on the VM.
　　Networking
　　config.vm.network :private_network, ip: "192.168.1.100"
　　Auto-running commands
　　config.vm.provision :shell, :inline => "sudo apt-get update"
　　config.vm.provision :shell, :path => "provision.sh"  (the location of the
　　script specified is relative to our project root, that is, /vagrant )
Provisioning
　　Puppet modules
　　http://docs.puppetlabs.com/references/latest/type.html
　　http://forge.puppetlabs.com/
　　puppet apply --modulepath=/home/michael/provision/modules /home/michael/provision/manifests/default.pp
　　独立运行模式
　　config.vm.provision :puppet do |puppet|
　　puppet.manifests_path = "provision/manifests"
　　puppet.manifest_file = "default.pp"
　　puppet.module_path = "provision/modules"
　　end
　　client/server模式
　　config.vm.provision :puppet_server do |puppet|
　　puppet.puppet_server = "puppet.internal.michaelpeacock.co.uk"
　　puppet.puppet_node = "vm.internal.michaelpeacock.co.uk"
　　end
　　SSH
　　config.vm.provision :shell, :path => "provision/setup.sh"
　　config.vm.provision :shell, :inline => "apt-get install apache2"
　　vagrant provision 命令可以重新进行provisioning
multiple virtual machines
　　Vagrantfile的配置
　　# -*- mode: ruby -*-
　　# vi: set ft=ruby :
　　Vagrant.configure("2") do |config|
　　config.vm.define :server1 do |server1|
　　server1.vm.box = "precise64"
　　server1.vm.network :private_network, ip: "10.11.1.100"
　　end
　　config.vm.define :server2 do |server2|
　　server2.vm.box = "precise64"
　　server2.vm.network :private_network, ip: "10.11.1.101"
　　end
　　end
　　1. Power up the project ( vagrant up )
　　2. Connect to  server1 ( vagrant ssh server1 )
　　3. Ping  server2 from  server1 ( ping 10.11.1.101
　　不同的配置
　　# -*- mode: ruby -*-
　　# vi: set ft=ruby :
　　Vagrant.configure("2") do |config|
　　config.vm.define :server1 do |server1|
　　server1.vm.box = "precise64"
　　server1.vm.network :private_network, ip: "10.11.1.100"
　　server1.vm.provision :puppet do |puppet|
　　puppet.manifests_path = "provision/manifests"
　　puppet.manifest_file = "server1.pp"
　　puppet.module_path = "provision/modules"
　　end
　　end
　　config.vm.define :server2 do |server2|
　　server2.vm.box = "precise64"
　　server2.vm.network :private_network, ip: "10.11.1.101"
　　server2.vm.provision :puppet do |puppet|
　　puppet.manifests_path = "provision/manifests"
　　puppet.manifest_file = "server2.pp"
　　puppet.module_path = "provision/modules"
　　end
　　end
　　end
