openstack-kilo，glance使用swift 作为后端存储

已用RDO安装好openstack

扩展swift的存储空间

rdo安装的swift存储的地方为2G左右/srv/node/swiftloopback ，太小需扩大
本实验环境，swift节点可以将某个磁盘再分个区使用，如下：

1>.fdisk /dev/nvme0n1 2>.mkfs.ext4 -s 1024 /dev/nvme0n1p2 3>.mkdir /srv/node/nvme0n1p2 4>.chown -R swift:swift /srv/node 5>.vi /etc/fstab,加一行如下： /dev/nvme0n1p2 /srv/node/nvme0n1p2 ext4 noatime,nodiratime,nobarrier,loop,user_xattr 0 0 6>.mount /srv/node/nvme0n1p2

配置swift

1>.cd /etc/swift/ 2>.查看 swift-ring-builder account.builder swift-ring-builder container.builder swift-ring-builder object.builder 3>.平滑添加 swift-ring-builder account.builder add z1-192.168.1.76:6002/nvme0n1p2 50 swift-ring-builder container.builder add z1-192.168.1.76:6001/nvme0n1p2 50 swift-ring-builder object.builder add z1-192.168.1.76:6000/nvme0n1p2 50 swift-ring-builder account.builder rebalance swift-ring-builder container.builder rebalance swift-ring-builder object.builder rebalance swift-ring-builder account.builder swift-ring-builder container.builder swift-ring-builder object.builder swift-ring-builder account.builder set_weight z1-192.168.1.76:6002/nvme0n1p2 100 swift-ring-builder container.builder set_weight z1-192.168.1.76:6001/nvme0n1p2 100 swift-ring-builder object.builder set_weight z1-192.168.1.76:6000/nvme0n1p2 100 swift-ring-builder account.builder swift-ring-builder container.builder swift-ring-builder object.builder swift-ring-builder account.builder rebalance swift-ring-builder container.builder rebalance swift-ring-builder object.builder rebalance 参考： http://blog.fatedier.com/2016/05/25/deploy-openstack-swift/ https://my.oschina.net/u/138210/blog/195570

3. 设置glance使用swift作为后端存储
修改一些

[glance_store] ...... stores=glance.store.filesystem.Store,glance.store.swift.Store,glance.store.http.Store default_store=swift swift_store_auth_address=http://192.168.1.76:5000/v2.0/ swift_store_user=services:glance swift_store_key=f2ec0b25ee4f42d2 //glance用户的keystone认证密码 swift_store_container=glance swift_store_create_container_on_put=True swift_store_large_object_size=5120 swift_store_large_object_chunk_size=200 os_region_name=RegionOne ......

重启glance服务或者整个重启服务
systemctl restart openstack-glance-api
openstack-service restart
4.登录dashboard的上传镜像，查看到镜像存储到swift里面了
ll /srv/node/nvme0n1p2/
