网络信息服务(NIS)是集中控制几个系统管理数据库的网络用品。
用户只需要在nis服务器上面创建,客户端加入nis域,直接可以使用Nis域上的用户来登录客户端。
1、相关服务:ypservNIS服务器端),ypbindNIS客户端),yppasswd(修改密码时,NIS客户端与NIS服务器端之前通过这个服务来通信)
2、相关端口:portmap 111,因为NISNFS 都是依赖于portmap服务  6.0版本用rpcbind取代portmap服务 ,我的系统是redhat 6.1
3、相关包:ypservNIS服务器必需的),ypbindNIS客户端必需的,默认已安装),yp-toolsNIS的常用工具,默认已安装)
环境信息如下:nis服务端ip:192.168.100.114   hostname:localhost  服务端i18n文件里配置的是中文
                          nis客户端ip:192.168.100.115    hostname:linux211

[root@localhost opt]#  echo "/bin/nisdomainname yezi.com">> /etc/rc.local        #每次开机自动加入nis域的命令
[root@localhost opt]#  service ypserv start         #启动ypserv
启动 YP 服务器的服务:[确定]     
[root@localhost opt]#  /usr/lib/yp/ypinit -m   #生成nis数据库每次添加用户之后,都需要重新生成nis数据库
At this point, we have to construct a listof the hosts which will run NIS
servers. localhost is in the list of NIS server hosts.  Please continue to add
the names for the other hosts, one perline.  When you are done with the
list, type a <control D>.
       next host to add:  localhost
       next host to add:  
The current list of NIS servers looks likethis:


localhost


Is this correct?  [y/n: y] y
We need a few minutes to build thedatabases...

localhost has been set up as a NIS masterserver.


Now you can run ypinit -s localhost on allslave server.

可以看到我的客户端是没有yezi这个用户的,现在我们做个试验,在服务端yezi目录下创建一个haha目录(注意主机名)
[root@localhostyp]# cd /opt/nishome/
[root@localhost nishome]# ls
yezi
[root@localhost nishome]# cd yezi/
[root@localhost yezi]# ls
[root@localhost yezi]# mkdir haha
[root@localhost yezi]# ls
haha
现在切换到客户端,
[root@linux211 ~]# su - yezi
[yezi@linux211 ~]$ ls
haha

可以看到服务端创建的目录啦。证明我们的nis搭建成功。
