Keystone Series IV: Deployment Keystone

A preface

The deployment of any software is no technical content, any deployment of the deployment of the people are charlatan.

The essence of deployment is copy, paste, enter. We domesticated a dog, and it can do the job.

We must not be pedantic when we engage in technology: credulity or unbelief.

Credulous fools like to learn only half of the Sunflower Treasure book, on the half of the book to teach you to practice this work will be the first self-palace, and the next half of the book said is not from the palace actually also can.

The idiot of the unbelief is like a horse in the winter what? What's a horse? What Winter plum?

Two version information

Official website http://docs.openstack.org/newton/install-guide-rdo/keystone.html

We follow the Newton this version to deploy, in fact, with everyone, OpenStack basically keep updating a version every 6 months, in the face of such a fast version of the change, we actually look at a version in-depth study, go deep into what level, for the community to submit code. Any master who deploys every new version will be a silly fork.

Mysql-u root-p#log in to databaseCREATE DATABASE Keystone;#New Library KeystoneGRANT all privileges the keystone.* to'Keystone'@'localhost'identified by'123';#new account for local access to the Keystone LibraryGRANT all privileges the keystone.* to'Keystone'@'%'identified by'123';#Create a new remote Access Keystone Library account

Install packages

# Keystone Package name Openstack-keystone # the reason for installing httpd and MOD_WSGI is that the community master pushes the Apache+keystone # Openstack-keystone Essence is a web app based on WSGI protocol, and HTTPD is essentially a Web server compatible with WSGI protocol, so we need to install HTTPD module for MOD_WSGI  -y install openstack-keystone httpd mod_wsgi

Configuration:/etc/keystone/keystone.conf

# let Openstack-keystone know how to connect to the back-end Database Keystone # Mysql+pymysql:pymysql is a python library that uses Python to manipulate MySQL native SQL  = mysql+pymysql://keystone:'123'@192.168.31.57/#  Fernet the way to generate tokens

Initializing the database Keystone

# The reason to initialize is because of Python's ORM Object Relational mapping, which requires initialization to generate the database table structure " keystone-manage Db_sync " Keystone
