To Setup and configure NIS on Redhat

Setup NIS Server

1. Look for ypserv packages and if it is not install install it.

# rpm -q ypserv*

If its not install follow the step,

# rpm -ivh ypserv*

2 . Enter the domain name in /etc/sysconfig/network file

# vi /etc/sysconfig/network

NISDOMAIN= lab.com

Save and quit

3. Edit the NIS client configuration file /etc/yp.conf

# vi /etc/yp.conf

ypserver 127.0.0.1

Save and quit

4. Start the NIS releated demons

# service portmap start

# service yppasswdd start

# service ypserv start

# chkconfig portmap on

# chkconfig yppasswdd on

# chkconfig ypserv on

5. Make sure all demons and service are running

# rpcinfo -p localhost

6. Initilize the NIS domain

# /usr/sbin/ypinit -m

next host to add : backup  (give the master server host name)

next host to add : ^D

Message will appear backup is your master server.

7.Start the ypxfrd and ypbind demons

# service ypbind start

# service ypxfrd start

# chkconfig ypbind on

# chkconfig ypxfrd on

8. Make sure demons are running

# rpcinfo -p localhost

9 . Add a new user

# useradd -g users nisuser

passwd nisuser

10. Confiure autofa to share /home directory

# vi /etc/auto.master

/home  /etc/auto.home

Save and quit.

# vi /etc/auto.home

* backup:/home/&

Save and quit.

Start auto fs service

# service autofs start

# chkconfig autofs on

11. Update the NIS domain authentication file in /var/yp

# cd /var/yp

# make

This will update the NIS authentication file

12. Now check user authentication is updated

# ypmatch nisuser passwd

Configure NIS Client

1.The authconfig-tui program automatically configures your NIS files after prompting you for the IP address and domain of the NIS server.

# authconfig -tui

2. Once finished, it should create an /etc/yp.conf file that defines, amongst other things, the IP address of the NIS server for a particular domain. It also edits the /etc/sysconfig/network file to define the NIS domain to which the NIS client belongs

# more /etc/yp.conf

# more /etc/sysconfig/network

3. Start NIS clients demons

# service portmap start

# service ypbind start

# chkconfig ypbind on

# chkconfig portmap on

Test NIS client access to NIS server

# ypmatch nisuser passwd

It will give the password home directory and all.

Try to login with the nisuser name from client

# su – nisuser

You will  be in user’s home directory.
