== Yellow Pages ==

The ''Network Information Service'' (NIS), also called ''Yellow Pages'' (YP) provides a single point for the entire cluster administration.

=== Configuration of the Master Node ===
* Set NIS domain name on the master node. Enter at the command line:
{{{
# domainname procksi.nis
}}}

* Add NIS domain name to ''/etc/sysconfig/network'':
{{{
NISDOMAIN = procksi.nis
}}}

* Modify ''/etc/yp.conf'':
{{{
ypserver 127.0.0.1
}}}

* Enable NIS server at boot time. Enter at the command line:
{{{
# /sbin/chkconfig --add ypserv
# /sbin/chkconfig --add yppasswdd
# /sbin/chkconfig ypserv on
# /sbin/chkconfig yppasswdd on
}}}

* Start the NIS server. Enter at the command line:
{{{
# /sbin/service ypserv start
# /sbin/service yppasswdd start
}}}

* Check that the NIS server is listening. Enter at the command line:
{{{
# rpcinfo -p localhost |grep yp
100009 1 udp 906 yppasswdd
100004 2 udp 938 ypserv
100004 1 udp 938 ypserv
100004 2 tcp 941 ypserv
100004 1 tcp 941 ypserv
}}}

* Initialise the NIS databases. Enter at the command line:
{{{
/usr/lib64/yp/ypinit -m
}}}

* Enable NIS clients at boot time. Enter at the command line:
{{{
# /sbin/chkconfig --add ypbind
# /sbin/chkconfig --add ypxfrd
# /sbin/chkconfig ypbind on
# /sbin/chkconfig ypxfrd on
}}}

=== Configuration of the Slave Nodes ===

* Add NIS domain name to ''/etc/sysconfig/network'':
{{{
NISDOMAIN = procksi.nis
}}}

* Modify ''/etc/yp.conf'':
{{{
domain procksi.nis server master01.procksi.local
}}}

* Enable NIS server at boot time. Enter at the command line:
{{{
/sbin/chkconfig --add ypbind
/sbin/chkconfig ypbind on
}}}

* Start the NIS server. Enter at the command line:
{{{
/sbin/service ypbind start
}}}

* Check that the NIS binding is listening. Enter at the command line:
{{{
# rpcinfo -p localhost |grep yp
100007 2 udp 856 ypbind
100007 1 udp 856 ypbind
100007 2 tcp 859 ypbind
100007 1 tcp 859 ypbind
}}}



== Add ProCKSI groups ==
Make the followign changes on the master node:

* Add new groups into ''/etc/group'':
{{{
procksi_admin:x:520:
procksi_dev:x:510:
}}}

== Add new Users ==
Make the following changes on the master node:

* Add new users into ''/etc/passwd'':
{{{
procksi:x:510:510:ProCKSI-Server:/home/procksi:/bin/bash
dxb:x:520:Daniel Barthel:/home/dxb:/bin/bash
}}}

* Add an entry for the new users into ''/etc/shadow'':
{{{
procksi:[Add Encrypted Password]:13483:0:99999:7:::
dxb:[Add Encrypted Password]:13755:0:99999:7:::
}}}

* Add a new procksi developers to group ''procksi_dev'' into ''/etc/group'', and new procksi administrator to ''procksi_admin''. Edit ''/etc/group'': add all users who should have access (e.g. ''dxb''):
{{{
procksi_admin:x:520:procksi, dxb procksi:x:510:dxb
procksi_dev:x:510:procksi, dxb
}}}


The members for group procksi are now: ''procksi'', ''dxb''

* Generate home directory for ''procksi'' at ''/home/procksi''. Enter at the command line of the master node:
{{{
mkdir /home/procksi
chown procksi.procksi /home/procksi
chmod 770 /home/procksi
}}}

* Whenever users, groups, passwords are modified, update the NIS configuration. Enter at the command line:
{{{
# cd /var/yp
# make
}}}
