Step-by-Step Guide to Setup NFS and Samba on Linux (Beginner Friendly)

 

📌 Introduction:

Sharing files across a network is a common task in Linux system administration. Two popular methods are NFS (Network File System) and Samba (SMB/CIFS).
In this guide, you’ll learn how to set up both NFS and Samba step-by-step, so you can enable file sharing between Linux and Windows systems.

🔧 Part 1: Setting Up NFS (Linux-to-Linux File Sharing)

✅ 1. Install NFS Packages

On both server and client:

bash
sudo yum install nfs-utils -y   # RHEL/CentOS
sudo apt install nfs-kernel-server nfs-common -y   # Ubuntu/Debian

---

✅ 2. Create Shared Directory on NFS Server

bash
sudo mkdir -p /srv/nfs_share
sudo chown nobody:nogroup /srv/nfs_share
sudo chmod 777 /srv/nfs_share

---

✅ 3. Configure NFS Exports

Edit the exports file:

bash
sudo nano /etc/exports

Add:

bash
/srv/nfs_share 192.168.1.0/24(rw,sync,no_subtree_check)

Then apply the export:

bash
sudo exportfs -a

---

✅ 4. Start and Enable NFS Services

bash
sudo systemctl enable --now nfs-server

---

✅ 5. Allow Firewall (RHEL-based systems)

bash
sudo firewall-cmd --permanent --add-service=nfs
sudo firewall-cmd --reload

---

✅ 6. Mount from NFS Client

On client machine:

bash
sudo mount 192.168.1.10:/srv/nfs_share /mnt

Make it permanent:

bash
echo "192.168.1.10:/srv/nfs_share /mnt nfs defaults 0 0" | sudo tee -a /etc/fstab

---

💡 NFS Use Cases

• Best for Linux-to-Linux file sharing

• Lightweight and fast for internal networks

---

🧰 Part 2: Setting Up Samba (Linux-to-Windows File Sharing)

✅ 1. Install Samba

bash
sudo yum install samba -y     # RHEL/CentOS
sudo apt install samba -y     # Ubuntu/Debian

---

✅ 2. Create Shared Folder

bash
sudo mkdir -p /srv/samba_share
sudo chown nobody:nogroup /srv/samba_share
sudo chmod 777 /srv/samba_share

---

✅ 3. Edit Samba Configuration

Open:

bash
sudo nano /etc/samba/smb.conf

Add at the end:

bash
[sambashare]
   path = /srv/samba_share
   browsable = yes
   read only = no
   guest ok = yes

---

✅ 4. Restart Samba Service

bash
sudo systemctl restart smb
sudo systemctl enable smb

---

✅ 5. Access From Windows

• Open File Explorer

• Type in address bar:
  \\192.168.1.10\sambashare

✅ Now you can copy/paste files between Linux and Windows!

---

🔒 Optional: Secure Samba with a Username

bash
sudo smbpasswd -a yourusername

Update smb.conf to require login:

java
   guest ok = no
   valid users = yourusername

📌 Conclusion

Both NFS and Samba are powerful file-sharing protocols.

• Use NFS when working Linux-to-Linux

• Use Samba for Linux-to-Windows or cross-platform sharing

Experiment with both to understand how Linux file sharing works in real time.
