NFS server on linux
-----------------------
Network file system
Introduction
---------------
NFS stands for network file system is a distributed file system protocol allows user on a client computer to access files over a computer network,Linux can be both NFS server and NFS client machine it means that it can export file system to other systems and mount file systems exported from other machines
Configuring NFS server
----------------------------
Let us start the process
---------------------------
Step -1: Install NFS server
use the following command to install the NFS server
sudo apt -get update -y
sudo apt - get install nfs-kernel-server
sudo yum update -y
sudo yum install nfs-utils nfs-utils-lib -y
Step-2: Create a directory called /nfs_share
mkdir /nfs_share
Step -3: edit the file /etc/exports and add the following line
vi /etc/exports
/nfs_share *(rw,sync)
/nfs_share - directory to be shared
*- clients allowed to accessthe share,you can restrict it by ip address ,for example ,you could ,instead of the asterik,put 192.168.0.0/24 to restrict the clients on the network
rw - read and write acsess
sync - sync the disk before command completion
Step -4: Now run the exportfs command to export the directory
exportrf -avr
-a -----> exports or un -exports all directories
-r------> re-export all directories
-u------->un -exports one or more directories
-v--------> provides verbose output
Step-5: Resatrt the services and make it permanaent
sudo service nfs restart
sudo systemctl restart nsf
if you want NFS to start at boot ,use the following command
chkconfig --levels 235 nfs on
sudo systemctl enable nsf
Configuring NFS client
----------------------------
Step-1: install nfs package on the client machine
sudo apt -get update -y
sudo apt -get install nfs-common -y
yum install nfs-utils nfs-utils-lib -y
Step-2: Start the service
sudo service nfs restart
sudo chkconfig --levels 235 nfs on
sudo systemctl start nsf
sudo sytemctl enable nsf
Step-3: Show mount Command to view exportson an NFS server
showmount -e 192.168.10.03
Step-4: Make a Directory and mount NFS over it
mkdir /nfs_data
mount -t nfs 192.168.10.03 :/nfs_share /nfs_data
Step -5: Make it permanaent mount
edit /etc/fstab and add the following line
vi /etc/fstab
192.168.10.03:/nfs_share /nfs_data nfs defaults 0 0
Once it mounted ,you can able to view the contents of the exported files /directory locally
