ProCKSI

h1. User Management

h2. Yellow Pages

The _Network Information Service_ (NIS), also called _Yellow Pages_ (YP) provides a single point for the entire cluster administration.

h3. Configuration of the Master Node

* Set NIS domain name on the master node. Enter at the command line:

<pre>

  # domainname procksi.nis

</pre>

* Add NIS domain name to _/etc/sysconfig/network_:

<pre>

  NISDOMAIN = procksi.nis

</pre>

* Modify _/etc/yp.conf_:

<pre>

  ypserver 127.0.0.1

</pre>

* Enable NIS server at boot time. Enter at the command line:

<pre>

  # /sbin/chkconfig --add ypserv  

  # /sbin/chkconfig --add yppasswdd

  # /sbin/chkconfig ypserv on

  # /sbin/chkconfig yppasswdd on

</pre>

* Start the NIS server. Enter at the command line:

<pre>

  # /sbin/service ypserv start

  # /sbin/service yppasswdd start

</pre>

* Check that the NIS server is listening. Enter at the command line:

<pre>

  # 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

</pre>

* Initialise the NIS databases. Enter at the command line:

<pre>

  /usr/lib64/yp/ypinit -m

</pre>

* Enable NIS clients at boot time. Enter at the command line:

<pre>

  # /sbin/chkconfig --add ypbind  

  # /sbin/chkconfig --add ypxfrd  

  # /sbin/chkconfig ypbind on

  # /sbin/chkconfig ypxfrd on

</pre>

h3. Configuration of the Slave Nodes

* Add NIS domain name to _/etc/sysconfig/network_:

<pre>

  NISDOMAIN = procksi.nis

</pre>

* Modify _/etc/yp.conf_:

<pre>

  domain procksi.nis server master01.procksi.local

</pre>

* Enable NIS server at boot time. Enter at the command line:

<pre>

  /sbin/chkconfig --add ypbind

  /sbin/chkconfig ypbind on

</pre>

* Start the NIS server. Enter at the command line:

<pre>

  /sbin/service ypbind start

</pre>

* Check that the NIS binding is listening. Enter at the command line:

<pre>

  # 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

</pre>

h2. Add [[ProCKSI]] groups

Make the followign changes on the master node:

* Add new groups into _/etc/group_:

<pre>

   procksi_admin:x:520:

   procksi_dev:x:510:

</pre>

h2. Add new Users

Make the following changes on the master node:

* Add new users into _/etc/passwd_: 

<pre>

   procksi:x:510:510:ProCKSI-Server:/home/procksi:/bin/bash

   dxb:x:520:Daniel Barthel:/home/dxb:/bin/bash

</pre>

* Add an entry for the new users into _/etc/shadow_: 

<pre>

   procksi:[Add Encrypted Password]:13483:0:99999:7:::

   dxb:[Add Encrypted Password]:13755:0:99999:7:::

</pre>

* Add new procksi developers to group _procksi_dev_ and new procksi administrator to _procksi_admin_. Edit _/etc/group_:

<pre>

   procksi_admin:x:520:procksi, dxb

   procksi_dev:x:510:procksi, dxb

</pre>

* Generate home directory for _procksi_ at _/home/procksi_. Enter at the command line of the master node: 

<pre>

   mkdir /home/procksi

   chown procksi.procksi /home/procksi

   chmod 770 /home/procksi

</pre>

* Whenever users, groups, passwords are modified, update the NIS configuration. Enter at the command line:

<pre>

  # cd /var/yp

  # make

</pre>
