在CentOS系统中安装NIS服务器的方法

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 passwd.byuid...
&nbsp;Updating group.byname...
&nbsp;Updating group.bygid...

&nbsp;Updating protocols.bynumber...
&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 │
│ │
│ │ Cancel │ │ Next │ │
│
│ │
└─────────────────────────────────
&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$
