第一步 安装 nis 服务器


复制代码

代码如下:

[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


复制代码

代码如下:

[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


复制代码

代码如下:

[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


复制代码

代码如下:

[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


复制代码

代码如下:

[root@s ~]# useradd e2fsck</p> <p>[root@s ~]# passwd e2fsck


 

5. 建立数据库


复制代码

代码如下:

[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
&nbsp;servers. www.e2fsck.org is in the list of NIS server hosts. Please continue to add
&nbsp;the names for the other hosts, one per line. When you are done with the
&nbsp;list, type a .
&nbsp;next host to add: www.e2fsck.org
&nbsp; 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>
&nbsp;The current list of NIS servers looks like this:
&nbsp;www.e2fsck.org
&nbsp;Is this correct? [y/n: y] <span id="comm">y</span>
&nbsp;We need a few minutes to build the databases...
&nbsp;Building /var/yp/e2fsck/ypservers...
&nbsp;Running /var/yp/Makefile...
&nbsp;gmake[1]: Entering directory `/var/yp/e2fsck'
&nbsp;Updating passwd.byname...

&nbsp;Updating protocols.byname...
&nbsp;Updating mail.aliases...
&nbsp;gmake[1]: Leaving directory `/var/yp/e2fsck'
&nbsp;www.e2fsck.org has been set up as a NIS master server.
&nbsp;Now you can run ypinit -s www.e2fsck.org on all slave server.
&nbsp;



6. 启动


复制代码

代码如下:

[root@s ~]# service yppasswdd start


 

第三步 客户端配置

1. 下载安装包


复制代码

代码如下:

[root@c2 ~]# yum install ypbind rpcbind


2. 图形方式认证


复制代码

代码如下:

[root@c2 ~]# authconfig-tui</p> <p>
authconfig-tui - (c) 1999-2005 Red Hat, Inc. 
┌───────┤ Authentication Configuration ├────—───| 
│ User Information Authentication │ 
│ [ ] Cache Information [*] Use MD5 Passwords │ 
│ [ ] Use Hesiod [*] Use Shadow Passwords │ 
│ [ ] Use LDAP [ ] Use LDAP Authentication │ 
│ [*] Use NIS [ ] Use Kerberos │ 
│ [ ] Use Winbind [ ] Use SMB Authentication │ 
│ [ ] Use Winbind Authentication │ 
│ [ ] Local authorization is sufficient │

│ 
│ │ 
└─────────────────────────────────
&nbsp;



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。


复制代码

代码如下:

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$
