Object 对象存储简介
Ceph Object Store
- RESTful Interface （RESTFul api实现对象的管理上传、下载）
- S3- and Swift-compliant APIs（提供2种风格 api，s3 和 Swift-compliant）
- S3-style subdomains
- Unified S3/Swift namespace （S3/Swift扁平空间）
- User management （安全行：用户认证）
- Usage tracking （使用率追踪）
- Striped objects (分片上传，在重组)
- Cloud solution integration （和云平台集成）
- Multi-site deployment （多站点部署）
- Multi-site replication （多站点复制）

对象存储网关架构
Ceph Object Gateway
Ceph Object Gateway is an object storage interface built on top of
librados to provide applications with a RESTful gateway to
Ceph Storage Clusters. Ceph Object Storage supports two interfaces:
- S3-compatible: Provides object storage functionality with an interface
that is compatible with a large subset of the Amazon S3 RESTful API. - Swift-compatible: Provides object storage functionality with an interface
that is compatible with a large subset of the OpenStack Swift API.
Ceph Object Storage uses the Ceph Object Gateway daemon (radosgw), which is
an HTTP server for interacting with a Ceph Storage Cluster. Since it
provides interfaces compatible with OpenStack Swift and Amazon S3, the Ceph
Object Gateway has its own user management. Ceph Object Gateway can store data
in the same Ceph Storage Cluster used to store data from Ceph File System clients
or Ceph Block Device clients. The S3 and Swift APIs share a common namespace, so
you may write data with one API and retrieve it with the other.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key: NGJ3JY6F45CTJJBWPGTJ
Secret Key: nJNchCzcaADsxbm9GLe6cquvGTMe9rvjZqDdXz2C
Default Region [US]:
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: 192.168.100.130
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: 192.168.100.130:80/%(bucket)s
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]: no
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:
New settings:
Access Key: NGJ3JY6F45CTJJBWPGTJ
Secret Key: nJNchCzcaADsxbm9GLe6cquvGTMe9rvjZqDdXz2C
Default Region: US
S3 Endpoint: 192.168.100.130
DNS-style bucket+hostname:port template for accessing a bucket: 192.168.100.130:80/%(bucket)s

Path to GPG program: /usr/bin/gpg
Use HTTPS protocol: False
HTTP Proxy server name:
HTTP Proxy server port: 0
Test access with supplied credentials? [Y/n] Y
Please wait, attempting to list all buckets...
