How to install NFS-SERVER on Oracle Linux
To Install and configure the NFS-SERVER on oracle linux
Introduction :
NFS (Network File System) is a distributed file system protocol that was developed by Sun Microsystem to allow a user on a client computer to access files over a network. The server stores data on its disks, and clients access it using messages in the protocol.
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

Step 3: start 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

Step 6: create folder for sharing by using the below command
[root@localhost /]# mkdir /nfs_share
Step 7 : create files in sharing folder by using the below command
[root@localhost nfs_share]# touch /nfs_share/abc{1..10}
Step 8 : verify the files are 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 export file is configure 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
[root@ client ~]# mkdir /home/linux/Desktop/nfs_acess
Step 18 : change the permission for 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 done in client machine by using the below command
[root@localhost]# cat /nfs_share/abc1
Test
With this process of Installation and configuration of the NFS-SERVER on oracle linux has comes to an End.
