OpenStack kilo版(3) Nova部署

部署在controller和compute节点

配置数据库

MariaDB [(none)]> CREATE DATABASE nova; 
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';       
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'127.0.0.1' IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.00 sec

MariaDB [(none)]> flush privileges ;
Query OK, 0 rows affected (0.00 sec)

project_name = service
username = nova
password = nova

#配置镜像服务
[glance] 
host = controller

#配置锁路径
