Setting up Simple NFS Server

• Creating a simple NFS accessible to all.
• vim /etc/exports
• /share *(rw,all_squash) <--all users will be match to nfsnobody user.
• mkdir /share
• chown nfsnobody /share <-- changed user ownership to nfsnobody upon using all_squash
• systemctl enable nfs-server
• systemctl start nfs-server
• exportfs -r         <--export only new configuration.
• showmount -e localhost
• firewall-cmd --permanent --add-service=nfs
• firewall-cmd --reload
• Mounting shared NFS 
• mount server2:/share /nfs

[root@server3 ~]# mount |grep nfs

sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime)

nfsd on /proc/fs/nfsd type nfsd (rw,relatime)

server2:/share on /nfs type nfs4 (rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.23.133,local_lock=none,addr=192.168.23.132)
