OpenStack Train版-2.安装keystone身份认证服务

1. 创建keystone数据库并授权
mysql -u root -proot
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 -y

3. 修改配置文件
cp -a /etc/keystone/keystone.conf{,.bak}
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

7. 创建服务所使用的项目
[root@controller ~]# openstack project create –domain default –description “Service Project” service
+————-+———————————-+

| name | service |
| options | {} |
