安裝NIS所需要的軟件包：
ypserv-2.19-3
yp-tools-2.9-0.1
ypbind-1.19-8.el5
portmap-4.0-65.2.2.1
這裏通過配置好的yum安裝：yum -y install yp*
# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server.example.com
NISDOMAIN=lanv_11
# vim /etc/yp.conf
domain lanv_11 service 192.168.137.254
---------添加一行
#service ypserv restart
-------------重啓ypserv
# cd /var/yp/
[root@server yp]# /usr/lib64/yp/ypinit -m ----------32位系統是[root@server yp]# /usr/lib/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers.
server.example.com 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 <control D>.
---------按ctrl +D 完成配置
next host to add:
server.example.com
next host to add:
The current list of NIS servers looks like this:
server.example.com
Is this correct?
[y/n: y]
y
We need a few minutes to build the databases...

server.example.com has been set up as a NIS master server.
Now you can run ypinit -s server.example.com on all slave server.

#mkdir /rhome
#useradd nisuser01 -d /rhome/nisuser01
#passwd nisuser01
#cd /var/yp

每建立一個用戶，要到/var/yp
更新即make
NIS的服務器設置好了
NFS服務配置：
nfs服務爲linux內核級服務，默認是已經裝好的
[root@server /]# vim /etc/exports
/rhome
192.168.137.0/255.255.255.0(rw,sync)
[root@server /]# service portmap restart
[root@server /]# service nfs restart
[root@server /]# showmount -e
Export list for server.example.com:
/rhome
192.168.137.0/255.255.255.0
即NIS+NFS服務器已經做好。
Client 端配置：
1：NIS client
要安裝NIS的軟件包有以下：
ypbind-1.19-8.el5
yp-tools-2.9-0.1
[root@station100 /]# vim /etc/resolv.conf
search example.com
nameserver 192.168.137.254
[root@station100 /]# system-config-authentication
[root@station100 /]# service ypbind restart
關閉 NIS 服務：
[確定]
關聯到 NIS 域：
[確定]
監聽 NIS 域服務器。.

設定每個用戶的home目錄大小爲500M，當用戶使用空間達到400M時將提出警告，但能繼續讀寫，當空間使用達到500M時，將不能繼續寫入數據。
爲了方便測試，我將用戶空間上線定爲200K，超過200K不能繼續寫入，超過100K提出警告
