CentOS 5 Configure NIS Server


Configure NIS Server

  Configure NIS Server in order to share users' accounts in your local networks.


[root@dir ~]# yum -y install ypserv


[root@dir ~]# ypdomainname srv.world   # set NIS domain name



[root@dir ~]# vi /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=dir.srv.world


# add follows to the end

NISDOMAIN=srv.world


[root@dir ~]# vi /var/yp/Makefile

# MERGE_PASSWD=true|false

# line 42: change

MERGE_PASSWD=false


# MERGE_GROUP=true|false

# line 46: change

MERGE_GROUP=false


# line 117: add

all: passwd shadow group hosts rpc services netid protocols


[root@dir ~]# vi /var/yp/securenets

255.0.0.0       127.0.0.0

255.255.255.0   10.0.0.0



[root@dir ~]# vi /etc/hosts

# add own IP address for NIS database

10.0.0.30       dlp.srv.world dlp


[root@dir ~]# /etc/rc.d/init.d/portmap start 

Starting portmap: [ OK ]


[root@dir ~]# /etc/rc.d/init.d/ypserv start 

Starting YP server services: [  OK  ]


[root@dir ~]# /etc/rc.d/init.d/yppasswdd start 

Starting YP passwd service: [  OK  ]


[root@dir ~]# chkconfig portmap on 

[root@dir ~]# chkconfig ypserv on 

[root@dir ~]# chkconfig yppasswdd on


[root@dir ~]# /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. dir.srv.world 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: dir.srv.world

next host to add: # Ctrl + D key

The current list of NIS servers looks like this:


dir.srv.world


Is this correct? [y/n: y] y # yes

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

Building /var/yp/srv.world/ypservers...

Running /var/yp/Makefile...

gmake[1]: Entering directory `/var/yp/srv.world'

Updating passwd.byname...

Updating passwd.byuid...

Updating shadow.byname...

Updating group.byname...

Updating group.bygid...

Updating hosts.byname...

Updating hosts.byaddr...

Updating rpc.byname...

Updating rpc.bynumber...

Updating services.byname...

Updating services.byservicename...

Updating netid.byname...

Updating protocols.bynumber...

Updating protocols.byname...

Updating mail.aliases...

gmake[1]: Leaving directory `/var/yp/srv.world'


dir.srv.world has been set up as a NIS master server.


Now you can run ypinit -s dir.srv.world on all slave server.


# It's neccessary to update NIS database with following way if new user is added again

[root@dir ~]# cd /var/yp 

[root@dir yp]# make
