服务填充至数据库
# su -s /bin/sh -c \结束安装
# systemctl enable openstack-glance-api.service \\ openstack-glance-registry.service
# systemctl start openstack-glance-api.service \\ openstack-glance-registry.service
验证操作
切换admin用户 $ . admin-openrc
17
下载源镜像
$ wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img 镜像上传并设置属性
$openstack image create \ --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public
验证是否成功
$openstack image list
计算服务
OpenStack计算服务主要包括以下组件：nova-api服务、nova-api-metadata服务、nova-compute服务、nova-scheduler服务、nova-conductor模块、nova-cert模块、nova-network worker模块、nova-consoleauth模块、nova-novncproxy守护进程、nova-spicehtml5proxy守护进程、nova-xvpvncproxy守护进程、nova-cert守护进程、nova客户端、队列、SQL数据库。
管理节点上安装与配置 基本配置
创建数据库表及用户 $ mysql -u root –p
18
执行以下SQL命令
CREATE DATABASE nova_api; CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \\ IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \\ IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \\ IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \\ IDENTIFIED BY 'NOVA_DBPASS';
切换用户获取认证 $ . admin-openrc
创建nova用户
$ openstack user create --domain default \\ --password-prompt nova User Password:（123456） Repeat User Password:
增加admin角色
$ openstack role add --project service --user nova admin
创建nova服务实体
$ openstack service create --name nova \\
--description \
创建计算服务的API endpoints
$ openstack endpoint create --region RegionOne \\
compute public http://Controller:8774/v2.1/%\\(tenant_id\\)s $ openstack endpoint create --region RegionOne \\
compute internal http://Controller:8774/v2.1/%\\(tenant_id\\)s $ openstack endpoint create --region RegionOne \\
