三 挂载cephfs文件系统
3.1 创建客户端用户
root@cephadm-deploy:/# ceph auth add client.wgs mon 'allow rw' mds 'allow rw' osd 'allow rwx pool=cephfs.wgs_cephfs.data'
added key for client.wgs
3.2 查看客户端用户信息
root@cephadm-deploy:/# ceph auth get client.wgs
[client.wgs]
key = AQAdtrBhxOX9BhAAbJtiqOdNrOAE/BmZc1mlyw==
caps mds = "allow rw"
caps mon = "allow rw"
caps osd = "allow rwx pool=cephfs.wgs_cephfs.data"
exported keyring for client.wgs
3.3 创建客户端用户keyring文件
root@cephadm-deploy:/# ceph auth get client.wgs -o ceph.client.wgs.keyring
exported keyring for client.wgs
3.4 验证客户端用户keyring文件
root@cephadm-deploy:/# cat ceph.client.wgs.keyring
[client.wgs]
key = AQAdtrBhxOX9BhAAbJtiqOdNrOAE/BmZc1mlyw==
caps mds = "allow rw"
caps mon = "allow rw"
caps osd = "allow rwx pool=cephfs.wgs_cephfs.data"
3.5 创建客户端用户key文件
root@cephadm-deploy:/# ceph auth print-key client.wgs > wgs.key
四 配置客户端
4.1 添加ceph源文件
root@ceph-client01:~# wget -q -O- 'https://mirrors.tuna.tsinghua.edu.cn/ceph/keys/release.asc' | sudo apt-key add -
OK
root@ceph-client01:~# echo "deb https://mirrors.tuna.tsinghua.edu.cn/ceph/debian-pacific $(lsb_release -cs) main" >> /etc/apt/sources.list
root@ceph-client01:~# apt -y update && apt -y upgrade
4.2 安装ceph-common
root@ceph-client01:~# apt -y install ceph-common
4.3 向同步客户端认证文件
root@cephadm-deploy:/# scp ceph.client.wgs.keyring wgs.key /etc/ceph/ceph.conf 192.168.174.121:/etc/ceph
4.4 客户端验证权限
root@ceph-client01:~# ceph --id wgs -s
cluster:
id: 0888a64c-57e6-11ec-ad21-fbe9db6e2e74
health: HEALTH_OK
