openstack pike版本安装笔记2(keystone认证组件安装)

	Identity:主要有两个功能
		keystone组件:
			用户管理：认证和授权
				token
				账号和密码
			服务目录：所有可用服务的信息库，包含API endpoint路径
			几个核心术语:
				User:用户相对于tanent而言的用户(类似于阿里云里的二级账号)
				Tanent:租户(类似于阿里云的主账号)
				Role：角色用于对用户授权
				Service：服务
				Endpoint：API访问的路径
				Token：令牌，用于认证
			keystone安装：
				yum install openstack-keystone
			配置文件(/etc/keystone/keystone.conf):
				[DEFAULT]#定义初始管理令牌的值：:
				admin_token = TOKEN_PASSWORD
				
				[database]#配置数据库访问：
				connection = mysql+pymysql://root:123456@con.colinshi.top/keystone
				
				[token]#配置Fernet UUID令牌的提供者。
				provider = fernet
			注：这里需要先在mysql上建立keystone数据库，并赋予相关访问权限
			初始化身份认证服务的数据库：
				su -s /bin/sh -c "keystone-manage db_sync" keystone
			初始化Fernet keys：
				keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
				keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
			引导身份服务：
				keystone-manage bootstrap --bootstrap-password 123456 --bootstrap-admin-url http://con.colinshi.top:35357/v3/ --bootstrap-internal-url http://con.colinshi.top:5000/v3/ --bootstrap-public-url http://con.colinshi.top:5000/v3/ --bootstrap-region-id RegionOne
			安装httpd：
				yum istall httpd mod-wsgi
			配置 Apache HTTP 服务器
				/etc/httpd/conf.d/wsgi-keystone.conf

				Listen 5000
				Listen 35357

				<VirtualHost *: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 *: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>
			
			启动 Apache HTTP 服务并配置其随系统启动：
				systemctl enable httpd.service
				systemctl start httpd.service
				
			创建项目(租户)(Service Project)：
				openstack project create --domain default --description "Service Project" service
			创建用户(demo)
				openstack user create --domain default <[--password-prompt]|[--password <password>]> demo
			创建角色授权role:
				openstack role create user
			将用户关联至租户和role上:
				openstack role add --project service --user demo user
				openstack role add --project service --user demo _member_
			将变量写入文件，方便直接调用:
				编辑文件 admin-openrc 并添加如下内容：
					export OS_PROJECT_DOMAIN_NAME=default
					export OS_USER_DOMAIN_NAME=default
					export OS_PROJECT_NAME=admin
					export OS_USERNAME=admin
					export OS_PASSWORD=123456
					export OS_AUTH_URL=http://con.colinshi.top:35357/v3
					export OS_IDENTITY_API_VERSION=3
					export OS_IMAGE_API_VERSION=2
				编辑文件 demo-openrc 并添加如下内容：
					export OS_PROJECT_DOMAIN_NAME=default
					export OS_USER_DOMAIN_NAME=default
					export OS_PROJECT_NAME=demo
					export OS_USERNAME=demo
					export OS_PASSWORD=demo
					export OS_AUTH_URL=http://con.colinshi.top:35357/v3
					export OS_IDENTITY_API_VERSION=3
					export OS_IMAGE_API_VERSION=2
