How to configure a NIS server on Centos 5.6

The headnode of our test cluster runs NIS. This is how to set it up.

Make sure you have the tools
yum -y install ypserv

Set the NIS domain and make it persistent
ypdomainname dori.cs.vt.edu Edit /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=dori.cs.vt.edu GATEWAY=128.173.236.1 NISDOMAIN=dori.cs.vt.edu

Configure the NIS make script to use the correct maps
Edit /var/yp/Makefile
MERGE_PASSWD=false MERGE_GROUP=false all: passwd shadow group hosts rpc services netid protocols mail

Configure what machines can talk to the NIS server
Edit /var/yp/securenets
host 127.0.0.1 host 128.173.236.229 255.255.0.0 172.16.0.0

Start the services NIS uses and make them start at boot
/etc/rc.d/init.d/portmap start /etc/rc.d/init.d/ypserv start /etc/rc.d/init.d/yppasswdd start chkconfig portmap on chkconfig ypserv on chkconfig yppasswdd on

Initialize the NIS database
When it asks about adding more NIS servers just use ctl-D
/usr/lib/yp/ypinit

Every time you add a new user you need to update the NIS database with this:
make -C /var/yp
