添加mon需要的文件

  • ceph.conf - The main ceph configuration file, which may be obtained from an existing ceph monitor

  • ceph.client.admin.keyring - The administrator key of the cluster, which may be obtained from an existing ceph monitor by ceph auth get client.admin -o /tmp/ceph.client.admin.keyring

  • ceph.mon.keyring - The monitor key, which may be obtained from an existinv ceph monitor by ceph auth get mon. -o /tmp/ceph.mon.keyring

  • monmap - The present monitor map of the cluster, which may be obtained from an existing ceph monitor by ceph mon getmap -o /tmp/monmap

为compute节点添加mon

  • 登录compute

ssh root@compute

  • 删除/etc/ceph/monnap

rm -rf /etc/ceph/monmap

  • 获取monmap

ceph mon getmap -o /etc/ceph/monmap

  • 创建mon

docker run -d \       --name mon1 \       -e MON_IP=10.64.0.53 \       -e MON_NAME=mon1 \       --net=host \       -v /etc/ceph:/etc/ceph \       -v /opt/mon1:/var/lib/ceph \       ceph/mon:hammer
