部署在controller节点
配置数据库
MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';
Query OK, 0 rows affected (0.00 se)
MariaDB [(none)]> flush privileges ;
Query OK, 0 rows affected (0.00 sec)
安装keystone
KeyStone服务的监听端口是5000和35357，配置Apache HTTP服务监听这两个端口，为了避免端口冲突，禁止KeyStone开机自启动：
root@controller:~# echo "manual" > /etc/init/keystone.override
安装keystone及相关软件包：
root@controller:~# apt-get install keystone python-openstackclient apache2 libapache2-mod-wsgi memcached python-memcache
生成admin token ：
root@controller:~# openssl rand -hex 10
38b35fc6a494b91f56cc
配置keystone
配置文件：/etc/keystone/keystone.conf
root@controller:~# vi /etc/keystone/keystone.conf
#[default]部分，配置初始admin_token
[DEFAULT]
verbose = True
admin_token = 38b35fc6a494b91f56cc
#[database]部分，配置数据库连接
[database]
connection = mysql://keystone:keystone@controller/keystone
#[memcache]部分，配置memcache服务
[memcache]
servers = 127.0.0.1:11211
#[revoke] 部分，配置SQL的撤回驱动
[revoke]
driver = keystone.contrib.revoke.backends.sql.Revoke
#[token]部分，配置UUID令牌的提供者和memcached的持久化驱动
[token]
provider = keystone.token.providers.uuid.Provider
driver = keystone.token.persistence.backends.sql.Token
初始化keystone数据库：
root@controller:~# su -s /bin/sh -c "keystone-manage db_sync" keystone
配置keystone的apache2接口
apache2.conf添加：
root@controller:~# vi /etc/apache2/apache2.conf
ServerName controller
创建/etc/apache2/sites-available/wsgi-keystone.conf文件，添加如下内容：
Listen 5000
Listen 35357
<VirtualHost *:5000>
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /var/www/cgi-bin/keystone/main
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
LogLevel info
ErrorLog /var/log/apache2/keystone-error.log
CustomLog /var/log/apache2/keystone-access.log combined
</VirtualHost>
<VirtualHost *:35357>
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /var/www/cgi-bin/keystone/admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
LogLevel info
ErrorLog /var/log/apache2/keystone-error.log
CustomLog /var/log/apache2/keystone-access.log combined
</VirtualHost>
启用身份认证服务的虚拟主机：
root@controller:~# ln -s /etc/apache2/sites-available/wsgi-keystone.conf /etc/apache2/sites-enabled/
为WSGI组件创建目录结构：
root@controller:~# mkdir -p /var/www/cgi-bin/keystone
WSGI组件：
root@controller:~# vi /var/www/cgi-bin/keystone/admin
import os
from keystone.server import wsgi as wsgi_server
name = os.path.basename(__file__)
application = wsgi_server.initialize_application(name)
root@controller:~# vi /var/www/cgi-bin/keystone/main
import os
from keystone.server import wsgi as wsgi_server
name = os.path.basename(__file__)
application = wsgi_server.initialize_application(name)
设置目录权限，并重启apache2：
root@controller:~# chown -R keystone:keystone /var/www/cgi-bin/keystone
root@controller:~# chmod 755 /var/www/cgi-bin/keystone/*
root@controller:~# service apache2 restart
* Restarting web server apache2 [ OK ]

其他
基于安全的原因，禁止校验令牌的机制
1、编辑 vi /etc/keystone/keystone-paste.ini：
移除 admin_token_auth从 [pipeline:public_api], [pipeline:admin_api], 和 [pipeline:api_v3] 部分
[pipeline:public_api]
pipeline = …
[pipeline:admin_api]
pipeline = …
[pipeline:api_v3]
pipeline = …
2、取消设置的操作系统环境变量：
root@controller:~# unset OS_TOKEN OS_URL
3、admin脚本，/root/admin-openrc.sh：
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL=http://$(hostname):35357/v3
export OS_IMAGE_API_VERSION=2
export OS_VOLUME_API_VERSION=2
export OS_REGION_NAME=RegionOne
export OS_COMPUTE_API_VERSION=3
export OS_IDENTITY_API_VERSION=2
