This article mainly introduces how to achieve ceph-rbd-based file sharing, the article is very detailed, has a certain reference value, interested friends must read it!

Ceph rbd can provide block devices for hosts, and we can implement a set of simple file sharing services by using block devices.

Dependent environment

1. First of all, the ceph client host kernel supports rados block driver. If not, please refer to the Linux kernel of ceph-rbd environment configuration (1). two。 Check to see if the client host already supports NFS.

# rpm-qa | grep nfs

3. Install NFS

# yum-y install nfs-utils rpcbind# yum install nfs-utilsceph-clinet create rbd block device # rados mkpool shareimage/ / create a separately shared pool# rbd create shareimage/share1-- size 10240 # rbd map shareimage/share1# rbd showmapped# mkfs.ext4-M0 / dev/rbd/shareimage/share1 # mkdir / mnt/nfs-share# mount-t ext4 / dev/rbd/shareimage/share1 / mnt/nfs-shareNFS server-side configuration # vim / etc/exports / mnt/nfs-share 10.20.room.* (rw No_root_squash,no_all_squash,sync)

Configuration file description: / mnt is the shared directory, that is, the directory where rbd is mounted, using an absolute path. 10.20.permission. * the IP that the client is allowed to access, () is the permission control.

Start NFS service # service rpcbind start# service nfs start client mount (any host with network segment 10.20.room.*) # mkdir / mnt/remote-share# showmount-e 10.20.16.177 / / 10.20.16.177:nfs-server ip# mount-t nfs / mnt/nfs-share / mnt/remote-share

Multiple hosts can be successfully mounted to test file sharing.
