How to share a folder between 2 servers with NFS
Server-side configuration
You need to install nfs-kernel-server
NFS is a pseudo filesystem. You will need to mount a folder with the option --bind :
mount --bind /home/user/folder_to_share /nfs_share/folderand set that permanently with :
/home/user/folder_to_share /nfs_share/folder none bind 0 0About permissions, put in /etc/idmapd.conf :
[Mapping]
Nobody-User = nobody
Nobody-Group = nogroupIt permits to the server and the client to doesn't share their UID et GUID
Then to activate the share, put in /etc/exports :
/nfs_share/ x.x.x.x/24(rw,fsid=0,insecure,no_subtree_check,async)
/nfs_share/nfs_test x.x.x.x/24(rw,nohide,insecure,no_subtree_check,async)Client-side configuration
You need to install nfs-common
Configuration is in /etc/default/nfs-common :
NEED_IDMAPD=yes (uid and guid will be matched based on name)Activate the NFS module with :
sudo modprobe nfsmount -t nfs4 -o proto=tcp,port=2049 IP_NFS_SERVER:/nfs_test /mntAnd then you should be able to read and write on the remote folder from the client. Thank you for reading. Tell me if anything goes wrong.

Nice one. You can also use SSHFS if you don't need the whole performance stuff, cannot setup new services or are concerned about encryption if you cannot install NFS 4 (providing that SSH is already set up on the remote of course).
