A very condensed post about setting up an example NFS server 192.0.2.1 and client 192.0.2.16. All actions as root.
Table of Contents
Configure the server 192.0.2.1
1 2 3 4 5 6 | sudo su apt update apt install nfs-kernel-server systemctl start nfs-kernel-server.service mkdir -p /data/acme nano /etc/exports |
And add this to file exports:
1 | /data/acme *(rw,sync,no_subtree_check) |
Next:
1 2 3 | exportfs -a
ufw status
ufw allow from 192.0.2.16 to any port nfs |
“ufw status numbered” list rules. To remove a rule – say number 5 – do “ufw delete 5”.
Configure the client 192.0.2.16
1 2 3 4 5 | sudo su apt update apt install nfs-common mkdir -p /data/nfs/acme nano /etc/fstab |
In fstab, add:
1 | 192.0.2.1:/data/acme /data/nfs/acme nfs defaults 0 0 |
Additional information
NFS can be hard to configure. Links below and specific searches can help.
One thing is important, communication between guest and host is based on user and group information and it is important to understand that uid and gid play a role here, they should be the same on host and guest. You have to retrieve them from a guest station (“id -u UserName” and “id -g UserName” returning for example 1003 and 1005) and a line in /etc/exports on the server can look like:
1 | /data/acme 192.0.2.16(rw,sync,all_squash,anonuid=1003,anongid=1005,no_subtree_check) |
