Vagrant基礎簡要記錄

Vagrant是一種開源軟件，它爲跨衆多操做系統構建可重複的開發環境提供了一種方法。Vagrant使用提供者(provider)來啓動隔離的虛擬環境。默認的提供者是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能夠幫助用戶管理/部署虛擬機的程序。docker是一個幫助用戶建立/運行/管理基於lxc的linux container的程序。coreos是一個專門爲運行linux container而設計的發行版。

安裝和使用

https://docs.vagrantup.com/v2/providers/ VMWare和Virtualbox等各類提供者

 

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的幾個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機器共享

Port forwarding

Vagrantfile 文件中進行端口映射

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

 

獨立運行模式

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 命令能夠從新進行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

 

不一樣的配置

# -*- 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

 

LAMP

根下的Vagrantfile文件內容

# -*- mode: ruby -*-

# vi: set ft=ruby :

  config.vm.provision :shell, :inline => "apt-get update"

 

  config.vm.box = "precise64"

 

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

 

  config.vm.provision :puppet do |puppet|

    puppet.module_path = "provision/modules"

    puppet.manifest_file  = "default.pp"
