NIS+AUTOFOFS+NFS

安装NIS所需要的软件包：
 
ypserv-2.19-3
 
yp-tools-2.9-0.1
 
ypbind-1.19-8.el5
 
portmap-4.0-65.2.2.1
 
这里通过配置好的yum安装：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
 -------------重启ypserv
 

 

# cd /var/yp/
 [root@server yp]# /usr/lib64/yp/ypinit -m ----------32位系统是[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...
 Building /var/yp/lanv_11/ypservers...
 Running /var/yp/Makefile...
 gmake[1]: Entering directory `/var/yp/lanv_11'

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.
 

[root@server yp]# make
 gmake[1]: Entering directory `/var/yp/lanv_11'

[root@server yp]# chkconfig portmap on
 [root@server yp]# chkconfig nfs on
 [root@server yp]# chkconfig ypserv on
 [root@server yp]# chkconfig ypbind on
 #mkdir /rhome
 #useradd nisuser01 -d /rhome/nisuser01
 #passwd nisuser01
 #cd /var/yp
 #make
 每建立一个用户，要到/var/yp
 更新即make
 NIS的服务器设置好了
 
NFS服务配置：
 nfs服务为linux内核级服务，默认是已经装好的
 [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服务器已经做好。
 Client 端配置：
 1：NIS client
 要安装NIS的软件包有以下：
 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
 关闭 NIS 服务：
 [确定]
 关联到 NIS 域：
 [确定]
 监听 NIS 域服务器。.
 
[root@station100 /]# ypcat passwd
 nisuser01:!!:502:503::/rhome/nisuser/nisuser01:/bin/bash
 nagios:$1$QOpN2J5B$6m0JEPGcXGCb7KDGMy/UA/:500:500::/home/nagios:/bin/bash
 test:!!:501:502::/home/nisuser/test:/bin/bash
 nisuser03:!!:504:505::/rhome/nisuser03:/bin/bash
 nisuser02:!!:503:504::/rhome/nisuser2:/bin/bash
 
2：autofs
 #vim /etc/auto.master
 /rhome
 /etc/auto.nis
 --timeout 60
 
----添加一行
 #cp /etc/auto.misc /etc/auto.nisuser
 #vim /etc/auto.nis
 #cd XXXX

 -rw,soft,intr
 server.example.com:/rhome/&
 
#service autofs restart
 #service portmap restart

 [root@station100 /]# ----------客户端本地root无法访问nis用户目录
 
设定每个用户的home目录大小为500M，当用户使用空间达到400M时将提出警告，但能继续读写，当空间使用达到500M时，将不能继续写入数据。
 为了方便测试，我将用户空间上线定为200K，超过200K不能继续写入，超过100K提出警告
