User and Keyring

• ceph auth get TYPE.ID
• ceph auth export TYPE.ID

对于以上命令，可以增加-o <file_name>，从而保存结果为keyring文件。

创建user

• ceph auth add
• ceph auth get-or-create
• ceph auth get-or-create-key

为user添加权限

• ceph auth caps 'allow [r|w|x|*|...] [pool=]
• ceph auth caps client.john mon ‘allow r’ osd ‘allow rw pool=liverpool’
• ceph auth caps client.paul mon ‘allow rw’ osd ‘allow rwx pool=liverpool’
• ceph auth caps client.brian-manager mon ‘allow *’ osd ‘allow *’
• ceph auth caps client.ringo mon ‘ ‘ osd ‘ ‘
