第一步 安裝 nis 服務器
[root@s ~]# yum install ypserv yp-tools rpcbind
這樣就安裝完成了，是不是很 easy
我這里的環境是:
NIS 服務器 IP: 192.168.100.254 主機名: www.e2fsck.org
NIS 客戶端 IP: 192.168.100.240 主機名: site.e2fsck.org
第二步 配置 NIS 服務器
1. 增加 NISDOMAIN
[root@s ~]# vi /etc/sysconfig/network</p><p>NISDOMAIN=e2fsck #這里的名字要和 HOSTNAME 一樣
2. 啟動 NIS 服務
[root@s ~]# service rpcbind start #如果是 CentOS 5 應該是 service portmap start</p><p>[root@s ~]# service ypserv start
3. 限制IP范圍
[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. 添加測試用戶
[root@s ~]# useradd e2fsck</p><p>[root@s ~]# passwd e2fsck
5. 建立數據庫
[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">這里 Ctrl + D 這里從服務器的地址，我們這里不用</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...
gmake[1]: Entering directory `/var/yp/e2fsck'

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. 啟動
[root@s ~]# service yppasswdd start
第三步 客戶端配置
1. 下載安裝包
[root@c2 ~]# yum install ypbind rpcbind
2. 圖形方式認證
[root@c2 ~]# authconfig-tui</p><p>
authconfig-tui - (c) 1999-2005 Red Hat, Inc.

這里選擇 Use NIS 然后下一步，Domain寫 e2fsck ；Server 寫IP 192.168.100.254 即可。
3. SSH測試
ssh 連接 192.168.100.240 用上面創建的 e2fsck 帳號查看是否登錄。
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$
