NIS(Network Information Service)使用来在共享需要在网络上所有主机上使用的信息的。NIS起源是Sun Microsystems的Yellow Page，但YP已经注册公司，所以就取了NIS这个名字, NIS服务器管理账户信息，如果所有客户机都在域中，那么只需要一台NIS服务器储存用户就可以了，不需要每台机子都存放[root@alicia ~]# yum install ypserver [root@alicia ~]# rpm -qa | grep yp ypbind-1.19-12.el5_6.1 ypserv-2.19-10.el5_9.1 yp-tools-2.9-2.el5
[root@alicia ~]# nisdomainname nis [root@alicia ~]# vi /etc/sysconfig/network 1 NETWORKING=yes 2 NETWORKING_IPV6=yes 3 HOSTNAME=alicia.net 4 NISDOMAIN=nis
[root@alicia ~]# vi /etc/rc.d/rc.local 1 #!/bin/sh 2 # 3 # This script will be executed *after* all the other init scripts. 4 # You can put your own initialization stuff in here if you don‘t 5 # want to do the full Sys V style init stuff. 6 7 touch /var/lock/subsys/local 8 nisdomainname nis
[root@alicia ~]# vi /etc/ypserv.conf 50 127.0.0.1/255.255.255.0 : * : * : none 51 10.8.118.0/255.255.255.0 : * : * : none 52 * : * : * : deny
[root@alicia ~]# useradd nis [root@alicia ~]# passwd nis Changing password for user nis. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully.
[root@alicia ~]# service ypserv restart
Stopping YP server services: [FAILED]
Starting YP server services: [ OK ]
[root@alicia ~]# /usr/lib/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers. centos 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: centos
next host to add: alicia.net
next host to add: alicia
next host to add:
The current list of NIS servers looks like this:
centos
alicia.net
alicia
Is this correct? [y/n: y] y
We need a few minutes to build the databases...

centos has been set up as a NIS master server.
Now you can run ypinit -s centos on all slave server.
