150.OpenStack Train版-2.安装keystone身份认证服务

1. 创建keystone数据库并授权

[root@controller ~]# mysql -uroot 
	CREATE DATABASE keystone;
	GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'KEYSTONE_DBPASS';
	GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'KEYSTONE_DBPASS';

2. 安装keystone软件包

[root@controller ~]# yum install openstack-keystone httpd mod_wsgi

3. 修改配置文件

[root@controller ~]# cp -a /etc/keystone/keystone.conf{,.bak}
[root@controller ~]# grep -Ev "^$|#" /etc/keystone/keystone.conf.bak > /etc/keystone/keystone.conf
	
[root@controller ~]# yum install -y openstack-utils

[root@controller ~]# openstack-config --set /etc/keystone/keystone.conf database connection  mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

[root@controller ~]# openstack-config --set /etc/keystone/keystone.conf token provider  fernet

4. 填充数据库

[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化Fernet密钥存储库
这是新版本的OpenStack的新功能，在Train版本下，keystone不再使用简单的字符串作为临时token，而是使用下面创建的fernet的用户来运行keystone。同时，keystone也不再对管理员用户和普通用户的服务端点区分使用不同的端口5000和35357，而是只使用5000端口不再使用35357端口。
[root@controller ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@controller ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

[root@controller ~]# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
  	--bootstrap-admin-url http://controller:5000/v3/ \
  	--bootstrap-internal-url http://controller:5000/v3/ \
  	--bootstrap-public-url http://controller:5000/v3/ \
  	--bootstrap-region-id RegionOne

5. 修改apache配置

[root@controller ~]# echo "ServerName controller" >> /etc/httpd/conf/httpd.conf

创建wsgi配置文件软链接
[root@controller ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

启动和开机自启动apache
[root@controller ~]# systemctl enable httpd.service
[root@controller ~]# systemctl start httpd.service

6. 初始化环境变量

[root@controller ~]# cat >> ~/.bashrc << EOF
	export OS_USERNAME=admin
	export OS_PASSWORD=ADMIN_PASS
	export OS_PROJECT_NAME=admin
	export OS_USER_DOMAIN_NAME=Default
	export OS_PROJECT_DOMAIN_NAME=Default
	export OS_AUTH_URL=http://controller:5000/v3
	export OS_IDENTITY_API_VERSION=3
	EOF
	
[root@controller ~]# source ~/.bashrc 
[root@controller ~]# openstack token issue
