2012/06/05
  Configure NIS Server in order to share users' accounts in your local networks.
[root@dlp ~]#
yum -y install ypserv rpcbind
[root@dlp ~]#
ypdomainname srv.world
 
# set NIS domain name

[root@dlp ~]#
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=dlp.srv.world
# add at the the last line

NISDOMAIN=srv.world
[root@dlp ~]#
vi /var/yp/Makefile
# MERGE_PASSWD=true|false
# line 50: change

# MERGE_GROUP=true|false

# line 125: add

[root@dlp ~]#
vi /var/yp/securenets
255.255.255.0   10.0.0.0

[root@dlp ~]#
vi /etc/hosts
# add own IP address

10.0.0.30   dlp dlp.srv.world

[root@dlp ~]#
systemctl start rpcbind.service

[root@dlp ~]#
systemctl start ypserv.service

[root@dlp ~]#
systemctl start yppasswdd.service

[root@dlp ~]#
systemctl enable rpcbind.service

[root@dlp ~]#
systemctl enable ypserv.service

[root@dlp ~]#
systemctl enable yppasswdd.service

[root@dlp ~]#
/usr/lib64/yp/ypinit -m
# update NIS database
At this point, we have to construct a list of the hosts which will run NIS servers. dlp is in the list of NIS server hosts. Please continue to add the names for the other hosts, one per line. When you are done with the
list, type a <control D>.
next host to add: dlp

next host to add:
# Ctrl + D key

The current list of NIS servers looks like this:
dlp
Is this correct? [y/n: y]
y
# answer yes

We need a few minutes to build the databases...

dlp has been set up as a NIS master server.
Now you can run ypinit -s dlp on all slave server.
# It's neccessary to update NIS database with following way if new user is added again

[root@dlp ~]#
cd /var/yp

[root@dlp yp]#
