NFS Service Deployment¶

Introduction¶

NFS (Network File System) allows different machines and operating systems to share files with each other over a network.

Prerequisites¶

• Access to the public internet

Basic Information and Compatibility¶

Installation Steps¶

1. Preparations¶

1.1 Disable Firewall Service¶

systemctl stop firewalld
systemctl disable firewalld

2. Installation¶

2.1 Install NFS Service¶

Run the following commands to install the necessary packages for the NFS server and create the mount directory (please ensure it's on a data disk, here using /nfsdata as the data directory)

yum install -y rpcbind nfs-utils
mkdir /nfsdata

2.2 Configure NFS Shared Path¶

Run the command vim /etc/exports to create the exports file, with the following content:

#/nfsdata *(insecure,rw,async,no_root_squash)
/nfsdata *(rw,no_root_squash,no_all_squash,insecure) 

2.3 Start NFS Service¶

Run the following commands to start the NFS service

systemctl enable rpcbind
systemctl enable nfs-server
systemctl restart rpcbind
systemctl restart nfs-server

2.4 Verify Configuration¶

Check if the configuration has taken effect

exportfs

Query the NFS shared directories on the local machine

showmount -e localhost

3. Verify Deployment¶

3.1 Install Client¶

Run the following command to install the necessary packages for the NFS client

yum install -y nfs-utils

3.2 View Shared Directories¶

Run the following command to check if the NFS server has set up any shared directories

# showmount -e $(NFS server IP)
showmount -e 192.168.100.105
# The output should look like this
Export list for 192.168.100.105:
/nfsdata *

3.3 Remote Mount Test¶

Run the following command to mount the shared directory from the NFS server to the local path /data

mkdir /data
# mount -t nfs $(NFS server IP):/nfsdata /data
mount -t nfs 192.168.100.105:/nfsdata /data
# Write a test file
echo "hello nfs server" > /data/test.txt

3.4 Check Test Results¶

On the NFS server, run the following command to verify that the file was written successfully

cat /nfsdata/test.txt

Successful test output:

hello nfs server
