Ceph&Openstack结合说明操作

openstack结合ceph操作文档

官方文档地址： http://docs.ceph.com/docs/master/rbd/rbd-openstack/

 

    1. 创建Pool池

        ceph osd pool create images 128  #128表示pg数

        ceph osd pool create volumes 512

 

    2. 创建对应账号

       

ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rx pool=images'    [client.cinder]          key = AQADmY1XW8MsJxAAds8zcRNKq+Jtb3PJox+Vhw==                             ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images'                     [client.glance]          key = AQAwmY1XdxMCGhAA+YUkZHYcrglYBu84BZ+enA==                             ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rbd_children'                     [client.cinder-backup]          key = AQBXmY1XA/r4FBAAPla8wuiigHFtFVkUrGLIXA==

 

    3. 同步到对应服务器 keyring 环文件

创建keyring  Collapse source
