        'LOCATION': 'controller:11211',
    },
}

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True    //开启domains版本支持 

OPENSTACK_API_VERSIONS = {    //配置API版本
    "identity": 3,
    "image": 2,
    "volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

OPENSTACK_NEUTRON_NETWORK = {
    'enable_router': False,
    'enable_quotas': False,
    'enable_distributed_router': False,
    'enable_ha_router': False,
    'enable_lb': False,
    'enable_firewall': False,
    'enable_***': False,
    'enable_fip_topology_check': False,
}

13.3 解决网页无法打开检查

vim /etc/httpd/conf.d/openstack-dashboard.conf

15.块cinder服务（contorller）

15.1 创建cinder数据库并授权

mysql -uroot -p
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder’@‘localhost’ IDENTIFIED BY ‘bigdata’;
GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder’@’%’ IDENTIFIED BY ‘bigdata’;

15.2 创建cinder用户

openstack user create --domain default --password bigdata cinder
openstack role add --project service --user cinder admin

15.2 创建cinderv2、cinderv3实体

openstack service create --name cinderv2 --description “OpenStack Block Storage” volumev2
openstack service create --name cinderv3 --description “OpenStack Block Storage” volumev3
在这里插入图片描述

15.3 创建块设备存储服务的 API 入口点

openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%(project_id)s
openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%(project_id)s
openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%(project_id)s
openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%(project_id)s
openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%(project_id)s
openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%(project_id)s

15.4 软件包安装

yum install openstack-cinder -y

15.5 修改配置文件

vim /etc/cinder/cinder.conf

[database]
connection = mysql+pymysql://cinder:bigdata@controller/cinder

[DEFAULT]
my_ip = 192.168.120.111
auth_strategy = keystone
transport_url = rabbit://openstack:bigdata@controller
