• cp1

host os->physical machine. guest os->vm

• cp2

vagrant global-status  //show all guest vm runnning on host machine.

to destroy vm, to ways

vagrant destroy  //must in folder
vagrant destroy 12345  //can be in any folder

if you shutdown a vm in virtubox, need to run

vagrant global-status --prune

port forwarding (note the order)

config.vm.network :forwarded_port, guest: 4567, host: 45670, host_ip: "127.0.0.1"

in boot up,

default: Forwarding ports...
default: 4567 => 45670 (adapter 1)

Then run

vagrant status

to check guest os status.

• cp3 init a guest os

vagrant init -m ubuntu/trusty32

-m :minimal Vagrantfile will be generated -f : will rewrite Vagrantfile if already exists

• cp4 download file, two syntax

$ curl [URL] -o [FILENAME]
$ curl http://xxx.box > xxx.box
$ wget -O [FILENAME] [URL]

• cp5 make first box:
  How to package:

vagrant package --output name.box

(Can be used for running or halted. If running, it will be shut down.)

list all boxes:

ls -la $VAGRANT_HOME/.vagrant.d/boxes/

Download box

vagrant box add [NAME] [ADDRESS]       //address may be http://, file:///

Ex:

vagrant box add first-box first-box.box

jekyll: build first page

jekyll new -f .
jekyll build
jekyll serve -H 0.0.0.0 --detach

Repackaging (first,delete old version box)

syntax: vagrant box repackage NAME PROVIDER VERSION

vagrant box repackage boxname

• cp6 provisioning, some possible usage:

config.vm.provision "PROVISIONER"
config.vm.provision "shell", path: "script.sh"
config.vm.provision "ansible", playbook: "playbook.yml"
config.vm.provision "shell", inline: "echo abc"

By default, provisioning is executed only during the first run of $ vagrant up
If you halt the system using $ vagrant halt or $ vagrant suspend, the next run of $ vagrant up will skip the provisioners.

vagrant up --provision
vagrant up --no-provision (turn off provisioners even already executed)

create a sh file(in host machine)

#!/usr/bin/env bash
echo "Installing: nodejs, lynx, ruby and jekyll"
apt-get update -y >>/tmp/provision-script.log 2>&1
apt-get install nodejs -y >>/tmp/provision-script.log 2>&1
apt-get install lynx-cur -y >>/tmp/provision-script.log 2>&1
apt-get install ruby1.9.1-dev -y >>/tmp/provision-script.log 2>&1
gem install jekyll >>/tmp/provision-script.log 2>&1

assign provisioner

vagrant up --provision-with x, y, z
vagrant up --provision-with shell

You can boot up guest os first by no provisioning

vagrant up --no-provision

then

vagrant provision

same on reload:

vagrant reload --provision
vagrant reload --no-provision
vagrant reload --provision-with shell

inline script

Vagrant.configure(2) do |config|
  config.vm.box = "vagrant"
  config.vm.network :forwarded_port, guest: ......

$script = <<SCRIPT

cd /vagrant
jekyll serve -H 0.0.0.0 --detach

SCRIPT

  config.vm.provision "shell", inline: $script, run: "always"

end

solve “not a tty” Problem
delete 'mesg n' in /root/.profile

vagrant up
vagrant ssh
sudo sed -i "/mesg n/d" /root/.profile

Create ansible provisioner

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible

• cp8 vm config

config.vm.provider "virtualbox" do |v|
    v.name = "my-project"
    v.gui = true
    v.memory = 4096
    v.cpus = 2
    v.customize ["modifyvm", :id, "--cpus", "2"]  #same as above
    v.customize ["modifyvm", :id, "--cpuexecutioncap", "50"]
end

package a iso file to box(?)

vagrant package --base my--project

run with debug mode:

vagrant up --debug

check guest ram

free m
cat /proc/meminfo
sudo lshw

memory test:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

config guest machine's hostname

Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu/trusty32"
  config.vm.hostname = "www.example.com"
  config.vm.post_up_message = "Finished"
  config.vm.boot_timeout = 1  #boot time. if exceeds,give prompt
  config.vm. graceful_halt_timeout = 5 #time before halt
  
  config.ssh.username
  config.ssh.password
  config.ssh.host
  config.ssh.port
  config.ssh.private_key_path
  config.ssh.insert_key = false #for public
  
  config.vm.box_download_checksum_type = "sha256"
  config.vm.box_download_checksum = "01234567890"
end

check using hostname -f
And change host os hostfile

127.0.0.1 www.example.com

Get checksum

# OS X
shasum -a 256 filename.box
# On Windows
openssl dgst -sha256 filename.box

Add box with checksum

vagrant box add boxname --checksum-type sha256 --checksum 123456 <link>

port collision.
Fix

config.vm.network :forwarded_port, guest: 80, host: 8800, auto_correct: true #if 8800 already used, may forward to 2201
config.vm.usable_port_range = (2200..2250)  #defaults to 2200..2250.

• cp10 multi machine management
  Ex:

Vagrant.configure(2) do |config|
  config.vm.define "web" do |web|
    web.vm.box = "chef/centos-6.5-i386"
    web.ssh.insert_key = false
    web.vm.provider "virtualbox" do |v|
      v.memory = 1024
    end
  end

  config.vm.define "db" do |db|
    db.vm.box = "ubuntu/trusty32"
  end
end

To start individual:

vagrant up web

define primary machine:

config.vm.define "web", primary: true do |web|
