一、数据库

1. [root@controller ~]# yum install -y openstack-keystone httpd mod_wsgi python2-openstackclient

2.创建keystone数据库

1. [root@controller ~]# mysql -uroot -p
2. MariaDB [(none)]> create database keystone;
3. Query OK, 1 row affected (0.00 sec)

3.建两个授权用户

（1）允许本地登录的数据库用户

1. MariaDB [(none)]> grant all on keystone.* to 'keystone'@'localhost' identified by 'redhat';
2. Query OK, 0 rows affected (0.00 sec)

（2）允许远程登录主机数据库的用户

1. MariaDB [(none)]> grant all on keystone.* to 'keystone'@'%' identified by 'redhat';
2. Query OK, 0 rows affected (0.00 sec)
4. MariaDB [(none)]> flush privileges;
5. Query OK, 0 rows affected (0.00 sec)

二、keystone配置文件

1.指定数据库的连接

1. [root@controller ~]# vim /etc/keystone/keystone.conf
2. [database]
3. connection = mysql+pymysql://keystone:redhat@controller/keystone
