How to Set Up NFS Server and Client Auto‑Mount on CentOS 7
This guide walks you through installing NFS on CentOS 7, creating a shared directory, configuring export options, starting the service, and then configuring a client to automatically mount the share using /etc/fstab, with verification steps included.
NFS Server Configuration
Install NFS service: yum install nfs-utils Create shared directory: mkdir -p /nfs/data Edit NFS exports file: Open /etc/exports and add the line: /nfs/data/ *(insecure,rw,sync,no_root_squash) The asterisk (*) denotes all clients, rw grants read‑write access, and sync forces synchronous writes. Other options such as no_root_squash control root permissions.
Apply NFS configuration: exportfs -ra Start NFS service:
systemctl start nfs
systemctl enable nfsVerify NFS service:
showmount -e 192.168.178.224NFS Client Configuration
Install NFS client: yum install nfs-utils Disable firewall (optional): Ensure the firewall allows NFS and rpcbind ports or temporarily disable it.
Edit /etc/fstab: Add the following line, replacing the server IP if needed:
192.168.178.224:/nfs/data /nfs/data nfs defaults 0 0Here 192.168.178.224:/nfs/data is the server export, /nfs/data is the local mount point, and nfs specifies the filesystem type.
Mount the NFS share: mount -a Or mount manually: mount 192.168.178.224:/nfs/data /nfs/data/ Verify the mount: df -h The output should list the NFS share with its size and usage.
These are the complete steps to configure an NFS service on CentOS 7 and set up a client for automatic mounting.
