ceph角色分配

配置ssh无密码登录

admin-node要可以无密码ssh登录osd机器，如果是普通用户，则要分配sudo权限，如下：

useradd -d /home/cephadmin -m cephadminecho "cephadmin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/cephadminchmod 0440 /etc/sudoers.d/cephadmin

快速安装

ceph-deploy new ceph2ceph-deploy install ceph2 ceph3 ceph4ceph-deploy --overwrite-conf mon create-initialceph-deploy admin ceph2 ceph3 ceph4ceph-deploy mgr create ceph2ceph-deploy osd create --data /dev/vdb1 ceph3ceph-deploy osd create --data /dev/vdb1 ceph4ceph healthceph -s

扩展

ceph-deploy mds create ceph2ceph-deploy mon add ceph3ceph-deploy mon add ceph4ceph quorum_status --format json-pretty

安装rgw

ceph-deploy rgw create ceph2调整配置[client.rgw.ceph2]rgw_frontends = "civetweb port=8080"ceph-deploy --overwrite-conf admin ceph2 ceph3 ceph4 ceph5systemctl restart ceph-radosgw@rgw.ceph2.servicecurl http://172.31.68.241:8080 -I

模拟client

apt-get install cephceph-deploy admin ceph5

对象存储
