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：
计算
安全
数据库
网络和加速
企业服务
useradd -d /home/cephadmin -m cephadmin
echo "cephadmin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/cephadmin
chmod 0440 /etc/sudoers.d/cephadminceph-deploy new ceph2
ceph-deploy install ceph2 ceph3 ceph4
ceph-deploy --overwrite-conf mon create-initial
ceph-deploy admin ceph2 ceph3 ceph4
ceph-deploy mgr create ceph2
ceph-deploy osd create --data /dev/vdb1 ceph3
ceph-deploy osd create --data /dev/vdb1 ceph4
ceph health
ceph -sceph-deploy mds create ceph2
ceph-deploy mon add ceph3
ceph-deploy mon add ceph4
ceph quorum_status --format json-prettyceph-deploy rgw create ceph2
调整配置
[client.rgw.ceph2]
rgw_frontends = "civetweb port=8080"
ceph-deploy --overwrite-conf admin ceph2 ceph3 ceph4 ceph5
systemctl restart ceph-radosgw@rgw.ceph2.service
curl http://172.31.68.241:8080 -Iapt-get install ceph
ceph-deploy admin ceph5echo 'hello ceph oject storage' > testfile.txt
创建pool
ceph osd pool create mytest 8
上传文件
rados put test-object-1 testfile.txt --pool=mytest
rados -p mytest ls
获取文件
rados get test-object-1 testfile.txt.1 --pool=mytest
查看映射位置
ceph osd map mytest test-object-1
删除文件
rados rm test-object-1 --pool=mytest
删除pool
ceph osd pool rm mytest mytest --yes-i-really-really-mean-itadmin上执行：ceph osd pool create rdb 8
admin上执行：rbd pool init rdb
admin上执行：
rbd create foo --size 512 --image-feature layering -p rdb
rbd map foo --name client.admin -p rdbadmin：ceph osd pool create cephfs_data 4
admin：ceph osd pool create cephfs_metadata 4
admin：ceph osd lspools
admin：ceph fs new cephfs cephfs_metadata cephfs_data
admin.secret内容为ceph.client.admin.keyring内容的一部分

内核级别挂载方法：
mkdir /mnt/mycephfs
mount -t ceph 172.31.68.241:6789,172.31.68.242:6789,172.31.68.243:6789:/ /mnt/mycephfs -o name=admin,secretfile=admin.secret
实验
cd /mnt/mycephfs
echo 'hello ceph CephFS' > hello.txt
cd ~
卸载
umount -lf /mnt/mycephfs
rm -rf /mnt/mycephfs
用户级别挂载：
mkdir /mnt/mycephfs
