大家好！
这次我们来学习Linux系统中的NIS服务器的配置。主要目标能够使用nis服务器中的账号登陆nis客户机
NIS服务器IP192.168.1.10 hostname = liflinux.nistest 该服务器下面有mike john2个账号
NIS客户机IP192.168.1.20
NIS初始配置：
首先配置NIS服务器：
1．检查服务器是否安装了下列包：portmap、ypserv、ypbind、yp-tools
ypserv在第一张安装光盘中，
[root@liflinux cdrom]# mount /media/cdrom/ 挂载
[root@liflinux /]# rpm -ivh /media/cdrom/RedHat/RPMS/ypserv-2.13-5.i386.rpm
warning: /media/cdrom/RedHat/RPMS/ypserv-2.13-5.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
Preparing... ########################################### [100%]
1:ypserv ########################################### [100%]
[root@liflinux /]# rpm -qa | grep portmap
portmap-4.0-63
[root@liflinux /]# rpm -qa | grep ^yp
yp-tools-2.8-7
ypserv-2.13-5
ypbind-1.17.2-3
2．设置time和time-udp服务的启动状态
[root@liflinux /]# chkconfig --list | grep time 默认设置
time-udp: off
daytime-udp: off
daytime: off
time: off
[root@liflinux /]# chkconfig time on
[root@liflinux /]# chkconfig time-udp on
[root@liflinux /]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
3．建立NIS的域名
[root@liflinux /]# nisdomainname nistest
[root@liflinux /]# cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/bin/nisdomainname nistest 添加这行使之开机运行
修改/etc/sysconfig/network文件，增加此行：NISDOMAIN=nistest
4.设置ypserv服务的配置文件
把下面这些添加到/etc/ypserv.conf最后
127.0.0.0/255.255.255.0 : * : * : none
192.168.1.0/255.255.255.0 : * : * : none
* : * : * : deny
[root@ liflinux /]# touch /etc/netgroup
[root@liflinux /]#hostname liflinux.nistest
[root@liflinux /]# cat /var/yp/securenets 需要自己建立
host 127.0.0.1
255.255.255.0 192.168.1.0
5．启动相关服务：
#service portmap restart
[root@liflinux /]# service portmap status
portmap (pid 1649) is running...
[root@liflinux /]# service ypserv start
Starting YP server services: [ OK ]
[root@liflinux /]# service yppasswdd start
Starting YP passwd service: [ OK ]
[root@liflinux /]# chkconfig --level 35 ypserv on
[root@liflinux /]# chkconfig --level 35 yppasswdd on 设置开机自动运行
6．初始化NIS数据库：
[root@liflinux /]# useradd user1
[root@liflinux /]# passwd user1
#/usr/lib/yp/ypinit –m
此时会询问是否有其他NIS服务器，如果没有，则可以直接按Ctrl+D结束，并重启ypserv服务。
#service ypserv restart
#service yppasswdd restart
同时检查进程是否正常运行以及信息是否正确：ps –aux | grep yp tail /var/log/message
以下进行客户端上的配置：
1．确认安装以下包： ypbind、yp-tools默认安装了的
2．设置hosts文件
[root@localhost ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.10 crliflinux NIS服务器的主机名
3．建立NIS域名
[root@crliflinux]# nisdomainname nistest
[root@crliflinux]# cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/bin/nisdomainname nistest 添加这行使之开机运行
修改/etc/sysconfig/network文件，增加此行：NISDOMAIN=nistest
4．设置yp.conf
[root@localhost ~]# cat /etc/yp.conf
# generated by /sbin/dhclient-script
domain domain.org broadcast
domain nistest 添加这句
ypserver crliflinuxistest
在/etc/passwd最下面添加
+::::::
5．设置nsswitch.conf
vi /etc/nsswitch.conf 修改为这样
passwd: files nis nisplus
shadow: files nis nisplus
group: files nis nisplus
#hosts: db files nisplus nis dns
hosts: files nis dns
6．启动ypbind服务程序
[root@localhost ~]# service portmap status
portmap (pid 1683) is running...
[root@localhost ~]# service ypbind start
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server..
在NIS服务器中输出NFS共享目录
在nis服务器上
[root@localhost ~]# vi /etc/exports 添加
/home 192.168.1.0/24(rw,async,np_root_squash)
[root@localhost ~]#service nfs start
在NIS客户机上
[root@localhost ~]#vi /etc/fstab
Crliflinuxistest:/home/ /home nfs defaults 0 0
