第一步 安装 nis 服务器
[root@s ~]# yum install ypserv yp-tools rpcbind
这样就安装完成了，是不是很 easy
我这里的环境是:
NIS 服务器 IP: 192.168.100.254 主机名: www.e2fsck.org
NIS 客户端 IP: 192.168.100.240 主机名: site.e2fsck.org
第二步 配置 NIS 服务器
1. 增加 NISDOMAIN
[root@s ~]# vi /etc/sysconfig/network</p> <p>NISDOMAIN=e2fsck #这里的名字要和 HOSTNAME 一样
2. 启动 NIS 服务
[root@s ~]# service rpcbind start #如果是 CentOS 5 应该是 service portmap start</p> <p>[root@s ~]# service ypserv start
3. 限制IP范围
[root@s ~]# vi /var/yp/securenets</p> <p>255.255.255.255 127.0.0.1
255.255.255.0 192.168.100.0
4. 添加测试用户
[root@s ~]# useradd e2fsck</p> <p>[root@s ~]# passwd e2fsck
5. 建立数据库
[root@s ~]# /usr/lib/yp/ypinit -m</p> <p>
At this point, we have to construct a list of the hosts which will run NIS
servers. www.e2fsck.org 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 .
next host to add: www.e2fsck.org
next host to add: <span id="comm">这里 Ctrl + D 这里从服务器的地址，我们这里不用</span>
The current list of NIS servers looks like this:
www.e2fsck.org
Is this correct? [y/n: y] <span id="comm">y</span>
We need a few minutes to build the databases...
Building /var/yp/e2fsck/ypservers...
Running /var/yp/Makefile...

www.e2fsck.org has been set up as a NIS master server.
Now you can run ypinit -s www.e2fsck.org on all slave server.
6. 启动
[root@s ~]# service yppasswdd start
第三步 客户端配置
1. 下载安装包
[root@c2 ~]# yum install ypbind rpcbind
2. 图形方式认证
[root@c2 ~]# authconfig-tui</p> <p>
authconfig-tui - (c) 1999-2005 Red Hat, Inc.

这里选择 Use NIS 然后下一步，Domain写 e2fsck ；Server 写IP 192.168.100.254 即可。
3. SSH测试
ssh 连接 192.168.100.240 用上面创建的 e2fsck 帐号查看是否登录。
login as: e2fsck
e2fsck@www.e2fsck.org’s password:
Could not chdir to home directory /home/e2fsck: No such file or directory
-bash-3.2$
