The following describes a procedure to set up NIS network name service under Red Hat Linux. This is geared toward a small intallation with only one domain. However, it should be fairly evident how to add more NIS domains. The NIS domain name has nothing to do with any DNS naming convention being used.
In these examples, the following conventions are used:
- NIS domain
- "internal"
- Code or configuration file data
- colored
- Root prompt on NIS master server
- master#
- Root prompt on NIS client host
- client#
Setting up a NIS master server
Required packages: yp-tools ypbind ypserv portmap
Set up "time" service to run via inetd/xinetd, or configure xntpd, or otherwise make sure the host's clock is synchronized.
- Edite /etc/yp.conf:
domain internal server ip.of.nis.server domain nismatrix server 192.168.0.99
Edite /etc/ypserv.conf:
.. dns: no files: 30 xfr_check_port: yes * : * : shadow.byname : port * : * : passwd.adjunct.byname : port
Edite /etc/sysconfig/network:
NISDOMAIN="nismatrix"
Setar NIS domain name:
one# domainname nismatrix one# ypdomainname nismatrix
Create file /var/yp/securenets:
host 127.0.0.1 255.255.255.0 10.0.0.0
Make sure the "portmap" service is running:
master# service portmap start master# chkconfig portmap on
Portmap will need a rule in /etc/hosts.allow to allow access from localhost and any hosts that need to access NIS.
Inicie o serviço ypserv:
one# service ypserv start
Verifique se está escutando
one# rpcinfo -u localhost ypserv program 100004 version 1 ready and waiting program 100004 version 2 ready and waiting
Inicialize o mapeamento NIS:
one# /usr/lib64/yp/ypinit -m
Especifique one.matrix, Ctrl-D, y, e deixe finalizar.
Inicie ypbind, yppasswdd, ypxfrd:
one# service ypbind start one# service yppasswdd start one# service ypxfrd start
Set YP services to run on boot-up:
one# chkconfig ypserv on one# chkconfig ypbind on one# chkconfig yppasswdd on one# chkconfig ypxfrd on
NIS client host setup
Required packages: yp-tools ypbind portmap
Edit /etc/sysconfig/network:
NISDOMAIN=internal
Edit /etc/yp.conf:
domain internal server ip.of.master.server
Edit /etc/hosts:
ip.of.master.server hostname.domain hostname
Set NIS domain-name:
client# domainname internal client# ypdomainname internal
Edit /etc/nsswitch.conf:
passwd: files nis shadow: files nis group: files nis
Make sure the portmap service is running:
client# service portmap start client# chkconfig portmap on
The /etc/hosts.allow file will need rules allowing access from localhost and the NIS master server.
Start ypbind service:
client# service ypbind start client# chkconfig ypbind on
Test it out:
client# rpcinfo -u localhost ypbind client# ypcat passwd
