ceph-rest-api 用例
1.版本问题
0.67-10.x版本如果需要集成现有业务可以考虑这个内置的rest接口，从12.x开始这个接口将被内置的mgr模块替代，后期可能会被移除，所以高版本就不要用这个接口了。
2.服务启动
root@demohost:/home/user# ceph-rest-api -c /etc/ceph/ceph.conf -n client.admin --cluster ceph

新建用户(keyring方式）
第一步，新建用户client.user1的keyring，内容如下
root@demohost:/usr/lib/python2.7/dist-packages# cat /tmp/user1.keyring
[client.user1]
key = AQCtsihaEUozABAAPPDTEhSNJMkj4HOp+nJeaQ==
caps mds = "allow"
caps mon = "allow *"
caps osd = "allow *"第二步，通过rest-api导入用户
root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/import -X PUT -T /tmp/user1.keyring第三步，查看用户信息
root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/get?entity=client.user1
[client.user1]
key = AQCtsihaEUozABAAPPDTEhSNJMkj4HOp+nJeaQ==
caps mds = "allow"
caps mon = "allow *"
caps osd = "allow *查看用户列表
root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/list
osd.0
key: AQDJ0adZpVCPIhAA8z/qYSPEX6Hn699piAS3bQ==
caps: [mon] allow rwx
caps: [osd] allow *

caps: [mon] allow rwx
caps: [osd] allow *

caps: [mon] allow rwx
caps: [osd] allow *

caps: [mds] allow
caps: [mon] allow *
caps: [osd] allow *5.其他操作
