Openstack I版 结合 Ceph 分布式存储 部署安装(三)

配置NOVA计算服务控制

安装服务

yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \
  openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \
  python-novaclient -y

同步ceph的配置文件

scp -r root@ceph-node01:/etc/ceph/ceph.conf root@controller:/etc/ceph/

备份nova配置文件

mv /etc/nova/nova.conf /etc/nova/nova.conf.bak

创建新的nova.conf
vi /etc/nova/nova.conf

修改配置文件权限

chown -R root:nova /etc/nova/nova.conf

同步导入nova数据库表

su -s /bin/sh -c "nova-manage db sync" nova

创建Nova管理员用户、角色、端点服务

keystone user-create --name=nova --pass=NOVA_PASS [email protected]
keystone user-role-add --user=nova --tenant=service --role=admin
keystone service-create --name=nova --type=compute \
  --description="OpenStack Compute" keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ compute / {print $2}') \ --publicurl=http://controller:8774/v2/%\(tenant_id\)s \ --internalurl=http://controller:8774/v2/%\(tenant_id\)s \ --adminurl=http://controller:8774/v2/%\(tenant_id\)s

启动nova相关服务

service openstack-nova-api start
service openstack-nova-cert start
service openstack-nova-consoleauth start
service openstack-nova-scheduler start
service openstack-nova-conductor start
service openstack-nova-novncproxy start
chkconfig openstack-nova-api on
chkconfig openstack-nova-cert on
chkconfig openstack-nova-consoleauth on
chkconfig openstack-nova-scheduler on
chkconfig openstack-nova-conductor on
chkconfig openstack-nova-novncproxy on

配置Glance镜像管理服务

安装组件

yum install openstack-glance python-glanceclient -y

备份glance配置文件

mv /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bak
mv /etc/glance/glance-registry.conf /etc/glance/glance-registry.conf.bak

创建api配置文件,其中指定ceph rbd 参数

Glance 创建image镜像

下载cirrros镜像文件

wget http://cdn.download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-disk.img

上传到glance管理

glance image-create --name "cirros-0.3.2-x86_64" --disk-format qcow2 --container-format bare --is-public True --progress < cirros-0.3.2-x86_64-disk.img

查看上传好的镜像,active为正常状态

[root@controller ~]# glance image-list
