  1. Install NIS packages and give nis domain name 
    apt -y install nis
    During installation enter private domain name for NIS
  2. Configure this server as NIS master server by editing '/etc/default/nis' and updating below two parameter values: 
    NISSERVER=master
    

    NISCLIENT=false
  3. Disable access to everyone and Allow NIS server access to sepecific subnet by editing '/etc/ypserv.securenets' as: 
    255.255.255.0	   <private-network-address>
    

    #0.0.0.0            0.0.0.0
  4. Initiate NIS database using 
    /usr/lib/yp/ypinit -m
  5. When prompted with 'When you are done with the list, type a <control D>.', press 'Ctrl+D'.
  6. Confirm 'y' on 'Is this correct? [y/n: y' prompt.
  7. Restart NIS service 
    systemctl restart nis
    

    systemctl enable nis
  8. Create user with home folder under /export/home 
    useradd -m  -d  /export/home/user1 -s /bin/bash user1
    

    passwd user1
  9. Update NIS user database 
    cd /var/yp
    

    make
    

    systemctl restart nis


In future whenever there is any change to /etc/passwd, /etc/group, /etc/shadow etc. (eg new user is added, user password is changed) then we need to run below command to update NIS database with latest information 

make -C /var/yp;  systemctl restart nis
