一、 Swift简介
openstack swift是openstack开源云计算项目开源的对象存储，提供了强大的扩展性、冗余和持久性
1.1 swift特性
极高的数据持久性
完全对称的系统架构
无限的可扩展性
无单点故障
1.2 对象存储在容器中
Openstack Swift API的用户模型与Amazon S3 API稍有不同。若要使用swift api通过rados网关的身份验证，需要rados网关用户帐户配置子用户
Amazon S3 API授权和身份验证模型具有单层设计。一个用户可以有多个access key和secret key，用于在同一帐户中提供不同类型的访问
而swift有租户概念，rados网关用户对应swift的租户，而子帐号则对应swift的api用户
RADOS网关支持Swift v1.0以及OpenStack keystone v2.0身份验证
二、swift 用户管理
2.1 创建Swift的子用户
[root@ceph5 ~]# radosgw-admin user info --uid joy
{ "user_id": "joy", "display_name": "Joy Ning", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [], "keys": [ { "user": "joy", "access_key": "5XCV68WUQJFFJPVM3UHK", "secret_key": "xhaA2YB1CA3xH54xLbmwPcglqjDyuFez36F8XGuG" } ], "swift_keys": [], "caps": [], "op_mask": "read, write, delete", "default_placement": "", "placement_tags": [], "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": 1024, "max_size_kb": 1, "max_objects": -1 }, "user_quota": { "enabled": true, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 }, "temp_url_keys": [], "type": "rgw" }
2.2 创建一个子账号
[root@ceph5 ~]# radosgw-admin subuser create --uid joy --subuser joy:swift --access=full
{ "user_id": "joy", "display_name": "Joy Ning", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [ { "id": "joy:swift", "permissions": "full-control" } ], "keys": [ { "user": "joy", "access_key": "5XCV68WUQJFFJPVM3UHK", "secret_key": "xhaA2YB1CA3xH54xLbmwPcglqjDyuFez36F8XGuG" } ], "swift_keys": [ { "user": "joy:swift", "secret_key": "6Ea8Cu94ea37ESj7mJWFV1TmoL9ffMjVHJ5D0vKK" } ], "caps": [], "op_mask": "read, write, delete", "default_placement": "", "placement_tags": [], "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": 1024, "max_size_kb": 1, "max_objects": -1 }, "user_quota": { "enabled": true, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 }, "temp_url_keys": [], "type": "rgw" }
创建另一个子账号
[root@ceph5 ~]# radosgw-admin subuser create --uid joy --subuser joy:swift2 --access=full
{ "user_id": "joy", "display_name": "Joy Ning", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [ { "id": "joy:swift", "permissions": "full-control" }, { "id": "joy:swift2", "permissions": "full-control" } ], "keys": [ { "user": "joy", "access_key": "5XCV68WUQJFFJPVM3UHK", "secret_key": "xhaA2YB1CA3xH54xLbmwPcglqjDyuFez36F8XGuG" } ], "swift_keys": [ { "user": "joy:swift", "secret_key": "6Ea8Cu94ea37ESj7mJWFV1TmoL9ffMjVHJ5D0vKK" }, { "user": "joy:swift2", "secret_key": "kJl6k4dVfqbOlZxdIX1Apmu5VFkL0KmSb5B8MkXz" } ], "caps": [], "op_mask": "read, write, delete", "default_placement": "", "placement_tags": [], "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": 1024, "max_size_kb": 1, "max_objects": -1 }, "user_quota": { "enabled": true, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 }, "temp_url_keys": [], "type": "rgw" }
2.3 删除一个子账号
[root@ceph5 ~]# radosgw-admin subuser rm --uid joy --subuser joy:swift2
{ "user_id": "joy", "display_name": "Joy Ning", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [ { "id": "joy:swift", "permissions": "full-control" } ], "keys": [ { "user": "joy", "access_key": "5XCV68WUQJFFJPVM3UHK", "secret_key": "xhaA2YB1CA3xH54xLbmwPcglqjDyuFez36F8XGuG" } ], "swift_keys": [ { "user": "joy:swift", "secret_key": "6Ea8Cu94ea37ESj7mJWFV1TmoL9ffMjVHJ5D0vKK" } ], "caps": [], "op_mask": "read, write, delete", "default_placement": "", "placement_tags": [], "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": 1024, "max_size_kb": 1, "max_objects": -1 }, "user_quota": { "enabled": true, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 }, "temp_url_keys": [], "type": "rgw" }
2.4 修改子用户秘钥
[root@ceph5 ~]# radosgw-admin key create --subuser joy:swift --gen-secret
{ "user_id": "joy", "display_name": "Joy Ning", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [ { "id": "joy:swift", "permissions": "full-control" } ], "keys": [ { "user": "joy", "access_key": "5XCV68WUQJFFJPVM3UHK", "secret_key": "xhaA2YB1CA3xH54xLbmwPcglqjDyuFez36F8XGuG" } ], "swift_keys": [ { "user": "joy:swift", "secret_key": "RB5SfO54XqgPl7TkfEjobfz9GP63dLIG1tZ9MQiq" } ], "caps": [], "op_mask": "read, write, delete", "default_placement": "", "placement_tags": [], "bucket_quota": { "enabled": false, "check_on_raw": false, "max_size": 1024, "max_size_kb": 1, "max_objects": -1 }, "user_quota": { "enabled": true, "check_on_raw": false, "max_size": -1, "max_size_kb": 0, "max_objects": -1 }, "temp_url_keys": [], "type": "rgw" }
三、使用swift客户端
3.1 安装swift客户端
[root@ceph1 ceph]# yum -y install python-swiftclient
3.2 创建一个容器
[root@ceph1 ceph]# swift -A http://ceph5.lab.example.com/auth/v1.0 -U joy:swift -K RB5SfO54XqgPl7TkfEjobfz9GP63dLIG1tZ9MQiq post swiftbk
3.3 向容器上传一个文件
[root@ceph1 ceph]# swift -A http://ceph5.lab.example.com/auth/v1.0 -U joy:swift -K RB5SfO54XqgPl7TkfEjobfz9GP63dLIG1tZ9MQiq upload swiftbk /etc/ceph/ceph.conf
3.4 服务器端查看
[root@ceph5 ~]# rados -p default.rgw.buckets.data ls --cluster backup
3.5 列出容器中的文件
[root@ceph1 ceph]# swift -A http://ceph5.lab.example.com/auth/v1.0 -U joy:swift -K RB5SfO54XqgPl7TkfEjobfz9GP63dLIG1tZ9MQiq list swiftbk
3.6 查看容器状态
[root@ceph1 ceph]# swift -A http://ceph5.lab.example.com/auth/v1.0 -U joy:swift -K RB5SfO54XqgPl7TkfEjobfz9GP63dLIG1tZ9MQiq stat swiftbk
