1. Install the NFS Server service. Once installed, query the status of the service, enable it for automatic start,
start it and then verify it is running.

2. Create the file NFS common file in the /etc/default directory. Add the setting that indicates that IDMAPD is
needed for NFS file sharing. Edit the IDMAP configuration file, add the domain of the server (Your SERVER1 Lab Server).
[root@tcox4 ~]# cd /etc/default/
[root@tcox4 default]# ll
total 12
-rw-r--r--. 1 root root 354 Sep 29 2014 grub
-rw-r--r--. 1 root root 1756 Mar 5 2015 nss
-rw-r--r--. 1 root root 119 Mar 6 2015 useradd
[root@tcox4 default]# vim nfs-common
(NOTE: Add the following line)
NEED_IDMAPD=YES
[root@tcox4 etc]# vim idmapd.conf
(NOTE: Add the following...)
DOMAIN = SERVER1.mylabserver.com (Again, note your lab server name will be different)
3. Using any method you choose, create a directory in the /mnt directory called 'share'. In this directory,
create a file with some text called 'shared.txt'.
[root@tcox4 etc]# mkdir /mnt/share
[root@tcox4 etc]# chmod 777 /mnt/share
[root@tcox4 etc]# echo "This is a test file" >> /mnt/share/shared.txt
4. Add this directory to the 'exports' file for NFS. Export the file system ONLY to the IP address of the client machine,
no other special options are required, limit the mount ONLY to that second server's IP.
[root@tcox4 etc]# vim /etc/exports
/mnt/share 172.31.117.2
(NOTE: Your IP will be different)
5. Restart the NFS server. Run the appropriate command to show the exported mounts on this localhost.
[root@tcox4 etc]# systemctl status nfs-server.service -l
