DevStack Quick Start

Create stack user (optional)

Devstack should be run as a non-root user with sudo enabled (standard logins to cloud images such as “ubuntu” or “cloud-user” are usually fine).

You can quickly create a separate stack user to run DevStack with.

$ sudo useradd -s /bin/bash -d /opt/stack -m stack

Since this user will be making many changes to your system, it should have sudo privileges:

$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

$ sudo su - stack

Download DevStack

$ git clone https://git.openstack.org/openstack-dev/devstack

$ cd devstack

The devstack repo contains a script that installs OpenStack.

Create local.conf file

Create a local.conf file at the root of the devstack git repo.

Host settings

[[local|localrc]]
# Multi-host settings
MULTI_HOST=False
HOST_IP=YOUR_IP_CONFIG
SERVICE_HOST=$HOST_IP
DATABASE_TYPE=mysql
MYSQL_HOST=$HOST_IP
RABBIT_HOST=$HOST_IP

Replace YOUR_IP_CONFIG with your host IP (e.g. 10.0.0.72 or localhost).
If you are not configuring OpenStack env in multi-host settings, please set MULTI_HOST=False.

Password settings

# Passwords
DATABASE_PASSWORD=123
ADMIN_PASSWORD=123
MYSQL_PASSWORD=123
RABBIT_PASSWORD=123
SERVICE_PASSWORD=123
SERVICE_TOKEN=ADMIN

Pre-set the passwords to prevent interactive prompts.

Enable services

#GIT_BASE=/opt/git

VNCSERVER_PROXYCLIENT_ADDRESS=$SERVICE_HOST
RECLONE=False
#enable Logging
LOGFILE=/opt/stack/logs/stack.sh.log
VERBOSE=True
LOG_COLOR=True
LOGDIR=/opt/stack/logs

Uncomment GIT_BASE configuration if you have a local git repo
enable_plugin cyborg will execute cyborg/devstack/plugin.sh and start cyborg service
The devstack logs will appear in $LOGDIR

Note

If you got version conflicts, please set PIP_UPGRADE to True in local.conf

Run DevStack

$ ./stack.sh

This will take a 30-40 minutes, largely depending on the speed of your internet connection. Many git trees and packages will be installed during this process.

It will speed up your installation if you have a local GIT_BASE.

Use OpenStack

Command line

You can source openrc YOUR_USER YOUR_USER (e.g. source openrc admin admin) in your shell, and then use the openstack command line tool to manage your devstack.

Horizon

You can access horizon to experience the web interface to OpenStack, and manage vms, networks, volumes, and images from there.
