Install OpenStack all in one centos 7

Introduction

In this tutorial, How to install OpenStack all in one Centos 7. OpenStack is open-source for setting up Infrastructure as a service. It provides a solution for both the public and private cloud.

For production a minimal OpenStack setup requires one controller and one compute node. To get started OpenStack is a practice to set up all-in-one deployment.

To install OpenStack “all-in-one” on CentOS 7, you can follow these steps:

Install OpenStack All in One Centos 7

My environment

• My Laptop use OS Linux Mint
• Installed Vagrant + VirtualBox

For example, I create a new Vagrantfile file Vagrant for OpenStack.

huupv@huupv-VivoBook-S15-X530UA:~/VMs_vagrant/Dev_Openstack$ cat Vagrantfile 

# The content as below
Vagrant.configure("2") do |config|
config.ssh.insert_key = false
config.vm.provider :virtualbox do |vb|
  vb.memory = 4500
  vb.cpus = 2
end
# Application server 1.
config.vm.define "app3" do |app3|
  app3.vm.hostname = "OpenstackDev"
  app3.vm.box = "centos/7"
  # app3.vm.network "private_network", ip: "172.20.19.31"
  app3.vbguest.installer_options = { allow_kernel_upgrade: true }
  app3.vm.network :forwarded_port, guest: 80, host: 8080
  app3.vm.network :forwarded_port, guest: 5000, host: 5000
  app3.vm.network :forwarded_port, guest: 9696, host: 9696
  app3.vm.network :forwarded_port, guest: 8774, host: 8774
  app3.vm.network :forwarded_port, guest: 35357, host: 35357
end
end

How to do it set up OpenStack for deployment

1. Prerequisites

To recommend/best practice for OpenStack disable Firewalld, NetworkManager, and SELinux.

Stop and disable NetworkManager

sudo systemctl stop NetworkManager
sudo systemctl disable NetworkManager

Stop and disable firewalld

sudo systemctl stop firewalld
sudo systemctl disable firewalld

Restart network service

sudo systemctl restart network

Disable SELinux

Can do it permanently in file /etc/selinux/config change SELINUX=enforcing to SELINUX=disabled.

Update your system.

sudo yum -y update

Configure a static IP address and set your hostname in /etc/hosts

Restart the machine.

2. Install OpenStack RPM

On CentOS, the Extras repository provides the RPM that enables the OpenStack repository.

sudo yum install -y centos-release-openstack-stein

3. Install Packstack

sudo yum install -y openstack-packstack

4. Deploy and run OpenStack using Packstack

sudo packstack --allinone

The output is below

[vagrant@OpenstackDev ~]$ sudo packstack --allinone
