五 Ceph 對象網(wǎng)關(guān)
Ceph對象網(wǎng)關(guān)是構(gòu)建在librados之上的對象存儲接口，它為應(yīng)用程序訪問Ceph存儲集群提供了一個RESTful風(fēng)格的網(wǎng)關(guān)。Ceph對象存儲支持2種接口：
- 兼容S3: 提供了對象存儲接口，兼容Amazon S3 RESTful接口的一個大子集。
- 兼容Swift: 提供了對象存儲接口，兼容Openstack Swift接口的一個大子集。
Ceph對象存儲使用Ceph對象網(wǎng)關(guān)守護(hù)進(jìn)程（radosgw），它是個與Ceph存儲集群交互的FastCGI模塊。因?yàn)樗峁┝伺cOpenStack Swift和Amazon S3兼容的接口，RADOS要有它自己的用戶管理。Ceph對象網(wǎng)關(guān)可與CephFS客戶端或Ceph塊設(shè)備客戶端共用一個存儲集群。S3和Swift接口共用一個通用命名空間，所以你可以用一個接口寫入數(shù)據(jù)、然后用另一個接口取出數(shù)據(jù)。

配置s3
cephyd@ceph-deploy:~/ceph-cluster$ s3cmd --configure
Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.
Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key: RNYDB5IUKJIQBZI2ZBB5
Secret Key: ybqB0VaeYR9WxGauO3xdyBQR9DKYX3PiEFj2b604
Default Region [US]:
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: 172.26.128.93:8000
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]: 172.26.128.93:8000/%(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]: False
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: RNYDB5IUKJIQBZI2ZBB5
Secret Key: ybqB0VaeYR9WxGauO3xdyBQR9DKYX3PiEFj2b604
Default Region: US
S3 Endpoint: 172.26.128.93:8000
DNS-style bucket+hostname:port template for accessing a bucket: 172.26.128.93:8000/%(bucket)s
Encryption password:
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...
Success. Your access key and secret key worked fine :-)
