  • 使用docker安装ceph

    使用docker安装ceph

    #划分子网
docker network create --driver bridge --subnet 172.20.0.0/16 ceph-network
docker network ls
docker network inspect ceph-network

#用于存放ceph配置
mkdir -p  /myceph/etc/ceph
#创建目录代表osd
mkdir -p  /myceph/osd/0  /myceph/osd/1  /myceph/osd/2

# monitor node
docker run -itd --name monnode --network ceph-network --ip 172.20.0.10 -e MON_NAME=monnode -e MON_IP=172.20.0.10 -v /myceph/etc/ceph:/etc/ceph ceph/mon

#
docker exec monnode ceph osd create
docker exec monnode ceph osd create
docker exec monnode ceph osd create

#osd
docker run -itd --name osdnode0 --network ceph-network -e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=monnode -e MON_IP=172.20.0.10 -v /myceph/etc/ceph:/etc/ceph -v /myceph/osd/0:/var/lib/ceph/osd/ceph-0 ceph/osd

docker exec monnode ceph -s

    基于Docker部署ceph分布式文件系统(Luminous版本)

  • empty-rgw

    remove osd

     ceph-deploy disk list node1 node2 node3 
  # ssh host
 systemctl stop ceph-osd@0

 ceph osd purge 0  --yes-i-really-mean-it
 ceph osd purge 1  --yes-i-really-mean-it
 ceph osd purge 2  --yes-i-really-mean-it

 ceph osd out  0
 ceph osd out  1
 ceph osd out  2

  • ceph 基本查询命令

    查看pool

    [root@node1 ~]# ceph osd lspools
1 .rgw.root
2 default.rgw.control
3 default.rgw.meta
4 default.rgw.log
5 default.rgw.buckets.index
6 default.rgw.buckets.data
7 default.rgw.buckets.non-ec
