ceph fs部署
ceph fs部署
[root@ceph1 cluster]# ceph osd pool create fs_data 128
pool 'fs_data' created
[root@ceph1 cluster]# ceph osd pool create fs_metadata 128
pool 'fs_metadata' created
[root@ceph1 cluster]#
[root@ceph1 cluster]# ceph fs new cephfs fs_metadata fs_data
new fs with metadata pool 4 and data pool 3
[root@ceph1 cluster]#
一:通过kernel 内核驱动挂载ceph fs
[root@ceph1 ~]# mkdir /cephfs_test
[root@ceph1 /]# cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQAMEkJZoYrvKRAAZTrXGSCvxiZ4NkVxoq8JHQ==
caps mds = "allow *"
caps mon = "allow *"
caps osd = "allow *"
[root@ceph1 /]# mount -t ceph xx.xx.xx.xx:6789:/ /cephfs_test -o name=admin,secret=AQAMEkJZoYrvKRAAZTrXGSCvxiZ4NkVxoq8JHQ==
[root@ceph1 /]#
[root@ceph1 /]# cd /cephfs_test
[root@ceph1 cephfs_test]# ls
[root@ceph1 cephfs_test]# mkdir 20170620
[root@ceph1 cephfs_test]# ls
20170620
[root@ceph1 cephfs_test]# rm -rf 20170620/
[root@ceph1 cephfs_test]# ls
[root@ceph1 cephfs_test]#
前述用法会把密码遗留在 Bash 历史里，更安全的方法是从文件读密码。例如：
[root@ceph01 /]# mount -t ceph xx.xx.xx.xx:6789:/ /kernel_cephfs -o name=admin,secretfile=/etc/ceph/admin.secret
二:FUSE方式
[root@ceph1 ~]# yum install ceph-fuse
