两个节点:ceph1、ceph2
网络配置:
ceph1: 管理网络,eth0,10.0.0.20
存储网络,eth1, 10.0.1.20
ceph2: 管理网络,eth0,10.0.0.21
存储网络,eth1, 10.0.1.21

部署osd.0
ps:无论osd在哪台服务器上,ceph osd creat都要在mon所在服务器上执行
root@ceph1:~# ceph osd create?
root@ceph1:~# ceph-osd -i 0 --mkfs --mkkey? ?
root@ceph1:~# ceph auth add osd.0 osd 'allow *' mon 'allow rwx' -i /var/lib/ceph/osd/ceph-0/keyring?
root@ceph1:~# ceph osd crush add osd.0 0.2 root=default host=ceph1
root@ceph1:~# ceph-osd -i 0
同理部署其他osd
ps: 不同服务器时,需先复制ceph.conf到对应服务器上
root@ceph1:~# ceph osd tree
