命令行裏登錄openstack的方式有兩種：
一種是密碼登錄： 在keystone裏存在已經創建的用戶和密碼
另外一種是token的方式登錄： 生成token，使用這個token登錄openstack
單獨如何安裝keystone：
生成一個token值，寫入keystone的配置文件中
# openssl rand -hex 10
寫入配置文件中
需要數據庫，安裝：
最好修改character=utf8 ，之後重啓服務
創建keystone數據庫：
MariaDB [keystone]> grant all privilegeson keystone.* to keystone@'%' identified by 'redhat';
Query OK, 0 rows affected (0.00 sec)
MariaDB [keystone]> grant all privilegeson keystone.* to keystone@'localhost' identified by 'redhat';
Query OK, 0 rows affected (0.00 sec)
MariaDB [keystone]> grant all privilegeson keystone.* to keystone@'192.168.179.140' identified by 'redhat';
Query OK, 0 rows affected (0.00 sec)
使用keystone用戶登錄到數據庫：
繼續修改keystone配置文件如下：
修改keystone的數據庫：
mysql://用戶名：密碼@數據庫的IP/數據庫名稱
keystone的服務端口，0.0.0.0 表示監聽所有的接口
管理端口35357
rabbitmq配置：
至此，配置完畢。
同步數據庫：
