CentOS 6 NFS的安装配置


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
