我使用的ceph.conf文件的内容
#!/bin/sh
conf="$1"
## fetch ceph.conf from some remote location and save it to $conf.
##
## make sure this script is executable (chmod +x fetch_config)
##
## examples:
##
## from a locally accessible file
## from a URL:
# wget -q -O $conf
## via scp
# scp -i /path/to/id_dsa user@host:/path/to/ceph.conf $conf
scp root@mon1.ihep.ac.cn:/usr/local/etc/ceph/ceph/conf $conf
4. 创建文件系统并启动。下面都做都在监控节点做。
#mkcephfs -a -c /usr/local/etc/ceph/ceph.conf --mkbtrfs
#mkdir /etc/ceph; cp /usr/local/etc/ceph/* /etc/ceph ##这个我记不清楚了，反正似乎有用
#/etc/init.d/ceph -a start
5. 挂载
#mkdir /ceph
#mount.ceph 192.168.56.107:/ /ceph
