Step 2. Start Services: Once the packages are installed start the services and enable to start on boot up:

[root@linuxcnf ~]# systemctl enable --now nfs-server

[root@linuxcnf ~]#

Step 3. Configure NFS Share Directory: Create a new directory and allow full access to the NFS clients for NFS share configuration:

[root@linuxcnf ~]# mkdir -p /opt/nfsshare
[root@linuxcnf ~]# chown -R nobody: /opt/nfsshare/
[root@linuxcnf ~]# chmod -R 777 /opt/nfsshare/
[root@linuxcnf ~]# ls -ld /opt/nfsshare/
drwxrwxrwx. 2 nobody nobody 1 Sep  1 08:47 /opt/nfsshare/
[root@linuxcnf ~]#

Modify /etc/export configuration and put the following parameters. Change the client address according to environment and access restrictions:

[root@linuxcnf ~]# vi /etc/exports
[root@linuxcnf ~]#

Save the file and export the shared directory for clients using following command:

[root@linuxcnf ~]# exportfs -r
