Matika版OpenStack伪生产环境部署-keystone

身份服务概述

OpenStack认证管理服务提供一个单点集成身份验证、授权和服务目录服务。其他OpenStack服务使用认证服务作为一个通用统一的API。此外,服务提供用户的信息,但不包括在OpenStack(如LDAP服务)可以集成到一个现有的基础设施。为了从认证服务中受益，其他OpenStack服务需要与身份认证服务协同工作。当一个OpenStack服务从用户那里接收一个请求，它检查与身份认证服务用户是否被授权请求。身份服务包含这些组件:

Server

一个集中的服务器使用RESTful接口提供身份验证和授权服务。

Drivers

驱动程序或服务后端集成到集中式服务器。他们是用于访问的身份信息存储库中的外部OpenStack,并且可能已经存在在OpenStack部署的基础设施(例如,SQL数据库或LDAP服务器)。

Modules

中间件模块运行在OpenStack组件的地址空间使用身份认证服务。这些模块拦截服务请求,提取用户凭证,并将它们发送到中央服务器进行授权。中间件模块和OpenStack组件之间的集成使用Python Web Server Gateway Interface。

前期需求

mysql -uroot -pSWPUcs406mariadb -e "CREATE DATABASE keystone;"
mysql -uroot -pSWPUcs406mariadb -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'SWPUcs406dbkeystone';"
mysql -uroot -pSWPUcs406mariadb -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'SWPUcs406dbkeystone';"
mysql -uroot -pSWPUcs406mariadb -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'controller' IDENTIFIED BY 'SWPUcs406dbkeystone';"
mysql -uroot -pSWPUcs406mariadb -e "FLUSH PRIVILEGES;"

安装配置组件

所有Controller节点：

yum install -y openstack-keystone httpd mod_wsgi openstack-utils

编辑 /etc/keystone/keystone.conf文件

openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token SWPUcs406token
openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:SWPUcs406dbkeystone@controller/keystone
openstack-config --set /etc/keystone/keystone.conf token provider fernet
openstack-config --set /etc/keystone/keystone.conf DEFAULT public_bind_host 10.0.0.1X
    openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_bind_host 10.0.0.1X

Controller1节点：

su -s /bin/sh -c "keystone-manage db_sync" keystone 
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
scp /etc/keystone/fernet-keys controller2:/etc/keystone/fernet-keys/

Controller2节点：

mkdir -p /etc/keystone/fernet-keys
chown -R keystone:keystone /etc/keystone/fernet-keys

所有Controller节点，配置HTTP服务

sed -i "s/#ServerName www.example.com:80/ServerName controller/" /etc/httpd/conf/httpd.conf
cat  > /etc/httpd/conf.d/wsgi-keystone.conf <<OFF
Listen 10.0.0.1x:5000
Listen 10.0.0.1x35357

<VirtualHost 10.0.0.1x:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-public
    WSGIScriptAlias / /usr/bin/keystone-wsgi-public
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost 10.0.0.1x:35357>
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-admin
    WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>
OFF

完成安装

systemctl enable httpd.service
systemctl start httpd.service

创建服务实体和API终端

在Controller1节点：

导入环境变量

export OS_TOKEN=SWPUcs406token
export OS_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

创建keystone服务

openstack service create --name keystone --description "OpenStack Identity" identity

创建endpoint

openstack endpoint create --region RegionOne identity public http://controller:5000/v3
openstack endpoint create --region RegionOne identity internal http://controller:5000/v3
openstack endpoint create --region RegionOne identity admin http://controller:35357/v3

创建default域

openstack domain create --description "Default Domain" default

创建用户角色

openstack role create admin
openstack role create user

创建admin用户

openstack project create --domain default --description "Admin Project" admin
openstack user create --domain default --password-prompt admin SWPUcs406admin
openstack role add --project admin --user admin admin

创建service项目

openstack project create --domain default --description "Service Project" service

创建demo用户

openstack project create --domain default --description "Demo Project" demo
openstack user create --domain default --password-prompt demo  SWPUcs406demo
openstack role add --project demo --user demo user

验证Keystone

删除/etc/keystone/keystone-paste.ini文件中[pipeline:public_api], [pipeline:admin_api], [pipeline:api_v3] 区域下的admin_token_auth

unset OS_TOKEN OS_URL
openstack --os-auth-url http://controller:35357/v3 \
  --os-project-domain-name default --os-user-domain-name default \
  --os-project-name admin --os-username admin token issue
