How to configure NFS Server on Oracle Linux

To Install and Configure the NFS-SERVER on Oracle Linux

Introduction:

Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems Its allow a user on a client computer to access files over a computer network The server stores data on its disks and the clients may request data through some protocol messages.

Installation steps:

Step 1: Check the OS version by using the below command

[root@localhost /]# cat /etc/os-release 
NAME="Oracle Linux Server"
VERSION="8.4"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="8.4"
PLATFORM_ID="platform:el8"
ORACLE_SUPPORT_PRODUCT_VERSION=8.4

Step 2: Install the NFS packages by using the below command

[root@localhost /]# yum install nfs-utils

Complete!

Step 3: Starting the NFS service by using the below command

 [root@localhost /]# systemctl start nfs-server.service

Step 4: Enable the NFS service by using the below command

 [root@localhost /]# systemctl enable nfs-server.service

Step 5: Check the status of NFS service by using the below command

  [root@localhost /]# systemctl status nfs-server.service 
● nfs-server.service - NFS server and services
   Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled; vendor preset: disabled)
   Active: active (exited) since Fri 2021-11-19 01:16:48 IST; 32s ago
 Main PID: 47153 (code=exited, status=0/SUCCESS)

Nov 19 01:16:48 localhost.localdomain systemd[1]: Started NFS server and services.

Step 6: Create folder for sharing by using the below command

 [root@localhost /]# mkdir /nfs_share

Step 7: Create files in the sharing folder by using the below command

 [root@localhost nfs_share]# touch /nfs_share/abc{1..10}

Step 8: Verify the files created using ls command

[root@localhost nfs_share]# ls /nfs_share
abc1  abc10  abc2  abc3  abc4  abc5  abc6  abc7  abc8  abc9

step 9: Edit the export file by using the below command

 [root@localhost nfs_share]# vim /etc/exports
/nfs_share	192.168.6.132(sync,rw)

Step 10: Check the exported file is configured correctly by using the below command

[root@localhost nfs_share]# exportfs -avr
exporting 192.168.6.0/23:/nfs_share

step 11: Print a brief information about the shares by using the below command

[root@localhost nfs_share]# exportfs -s
/nfs_share  192.168.6.0/23(sync,wdelay,hide,no_subtree_check,sec=sys,rw,secure,root_squash,no_all_squash)

Step 12: Install client packages by using the below command

[root@ client ~]# yum install nfs-utils nfs4-acl-tools
Loaded plugins: langpacks, ulninfo
Package 1:nfs-utils-1.3.0-0.68.0.1.el7.2.x86_64 already installed and latest version
Package nfs4-acl-tools-0.3.3-21.el7.x86_64 already installed and latest version
Nothing to do

Step 13: Start the NFS service by using the below command

root@ client ~]# systemctl start nfs-utils.service 

Step 14: Enable the NFS service by using the below command

[root@ client ~]# systemctl enable  nfs-utils.service 

Step 15: Check the status of NFS by using the below command

[root@ client ~]# systemctl status  nfs-utils.service 
● nfs-utils.service - NFS server and client services
   Loaded: loaded (/usr/lib/systemd/system/nfs-utils.service; static; vendor preset: disabled)
   Active: active (exited) since Fri 2021-11-19 03:39:17 IST; 12s ago

Step 16: Check the shares from the server by using the below command

[root@ client ~]# showmount -e 192.168.6.132
Export list for 192.168.6.132:
/nfs_share 192.168.6.0/23

Step 17: create a directory for mount the server shares by using the below command

[root@ client ~]# mkdir  /home/linux/Desktop/nfs_acess

Step 18: Change the permission to the folder by using the below command

[root@client ~]# chmod -R 777  /home/linux/Desktop/nfs_access

Step 19: Mount the server shares into local directory by using the below command

[root@ client ~]# mount -t nfs  192.168.6.132:/nfs_share /home/linux/Desktop/nfs_access

Step 20: change the shared folder permissions in server by using the below command

[root@localhost]# chmod -R 777 /nfs_share/  

Step 21: Verify the changes that was made in client machine by using the below command

 [root@localhost]# cat /nfs_share/abc1 
Test

The Installation and configuration of the NFS-SERVER on oracle linux has come to an End.
