Openstack with Packstack¶

packstack¶

vagrant¶

สร้าง directory ชื่อ openstack และภายในมี Vagrantfile ดังนี้

# -*- mode: ruby -*-
# vi: set ft=ruby :

$script = <<SCRIPT
echo "run provisioning..."
echo 'root:password' | sudo chpasswd
sudo sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config
yum install -y epel-release
yum install -y centos-release-openstack-mitaka
yum update -y
yum install -y openstack-packstack

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.define :controller do |node|
            node.vm.network :private_network, :ip => "10.0.0.10"
            node.vm.network :private_network, :ip => "20.0.0.10"

เข้าไปยัง controller

    vagrant ssh controller
sudo su -
//set selinux to disable
getenforce
sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config
--or--
vi /etc/selinux/config

setenforce 0

upload image¶

(packstack จะสร้าง ไฟล์ keystonerc_admin ใช้สำหรับการ login ทาง commandline)
