Linux: Network File System (NFS) - Paiet/Tech-Journal-for-Everything GitHub Wiki

Network File System
- Allow sharing files over the network
- Developed as a standard protocol
- Used by *NIX and macOS
  - Can be added to Windows
Configuring an NFS Server
1. Install NFS (if necessary)
  - yum install nfs-utils libnfsidmap
2. Enable and Start Services
  - systemctl enable --now rpcbind nfs-server rpc-statd nfs-idmapd
3. Create a folder to share
  - mkdir -pm 777 /export/share
4. Add the folder to the export list
  - sudo vi /etc/exports
  - /export/share 10.0.0.0/16(rw,sync,no_root_squash)
5. Reload the config file
  - sudo exportfs -r
  - sudo exportfs -v to verify
6. Allow clients through the firewall
  - firewall-cmd --permanent --zone public --add-service mountd
  - firewall-cmd --permanent --zone public --add-service rpc-bind
  - firewall-cmd --permanent --zone public --add-service nfs
  - firewall-cmd --reload
Configuring an NFS Client
1. Install NFS (if necessary)
  - yum install nfs-utils libnfsidmap
2. Enable and Start rpcbind
  - systemctl enable rpcbind
  - systemctl start rpcbind
3. Test if share is accessible
  - showmount -e <server_ip>
4. Mount the share to a local folder
  - sudo mkdir /mnt/share
  - mount <server_ip>:/export/share /mnt/share
5. (Optional) Add to fstab to mount during boot
  - sudo vi /etc/fstab
  - <server_ip>:/export/share /mnt/share nfs rw,sync,hard,intr 0 0
