NFS的安装配置：
centos 5 :
yum install nfs-utils portmap
centos 6 :
yum install nfs-utils rpcbind
本节是使用centos 6的配置过程：
设备：两台 centos6 OS 安装的时候选择的是"Basic Server"软件配置包。
首先，让两台机器都安装NFS的 软件包，如下显示的是服务器端：
[root@roothomes /home]$ yum install nfs-utils rpcbind
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: centos.ustc.edu.cn
* extras: centos.ustc.edu.cn
* updates: centos.ustc.edu.cn

[root@roothomes /home]$
服务器端：
###(建立挂载的目录，并且挂载目录。)
[root@roothomes /etc]$ mkdir /opt/centos6
[root@roothomes /etc]$ cd /opt/centos6/
[root@roothomes /opt/centos6]$ mkdir thisISnfsFile
[root@roothomes /opt/centos6]$ ls
thisISnfsFile
[root@roothomes /etc]$ vi /etc/exports
[root@roothomes /opt/centos6]$ cat /etc/exports
/opt/centos6 192.168.1.0/24(ro,no_root_squash)
### 备注:/opt/centos6表示nfs共享的目录 192.168.1.0-192.168.1.254区间的IP可以访问，访问权限是自读，root 用户
###(启动对应的服务)
[root@roothomes /opt/centos6]$ chkconfig nfs on
[root@roothomes /opt/centos6]$ /etc/init.d/rpcbind start
[root@roothomes /opt/centos6]$ /etc/init.d/nfs start
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@roothomes /opt/centos6]$ service iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
客户端：
[root@roothomes /home]$ yum install nfs-utils rpcbind
安装完毕！
[root@vmBS00 ~]# service iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
###查看是否能访问nfs服务
[root@vmBS00 ~]# showmount -e 192.168.1.75
Export list for 192.168.1.75:
/opt/centos6 192.168.1.0/24
[root@vmBS00 ~]# mkdir /opt/centos6
[root@vmBS00 ~]# mount -t nfs 192.168.1.75:/opt/centos6/ /opt/centos6/
[root@vmBS00 ~]# ls /opt/centos6/
thisISnfsFile
###配置开机自动挂载
[root@vmBS00 ~]# vi /etc/fstab
### 添加 #192.168.1.75:/opt/centos6/ /opt/centos6/ nfs nodev,ro,rsize=32768,wsize=32768 0 0
[root@vmBS00 ~]# init 6
