NFS
Network File System (NFS) is a distributed file system protocol that allow to share files and folders using a TCP network.
Installation
apt install nfs-common apt install nfs-kernel-server
systemctl status nfs-server.service
Commands
exportfs(apt install nfs-kernel-server)
Example output NFS share to everyone:
HOST#exportfs
/nfs <world>
showmount Hosts on SERVER_NAME:
showmount -e Export list for SERVER_NAME:
showmount clnt_create: RPC: Program not registered
showmount -e
Restart service: systemctl start nfs-server
Configuration files
/etc/exports [1]
Example:
/export 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async) /export/users 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,async)
fsid=0signals the NFS server that this export is the root.
Warning: /etc/exports is affected by adding additional space characters, be mindful about format
NFSv4
NFSv4 no longer utilizes the MOUNT protocol.
Activities
- Setup a NFS server in Ubuntu following: https://help.ubuntu.com/community/SettingUpNFSHowTo
- Install server:
apt-get install nfs-kernel-server - Install client (optional):
apt-get install nfs-common
- Install server:
- Mount a remote nfs share:
mount -t nfs -o proto=tcp,port=2049 REMOTE_IP_SERVER:/REMOTE_SHARE_DIR /YOUR/LOCAL_DIR/
mount -t nfs4 10.10.10.2:/ ./
mount: /mnt: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program
(Install client: apt-get install nfs-common)
