Linux nfs服务器

来源：互联网发布：程序员试用期自我评价编辑：程序博客网时间：2024/06/15 09:05

一安装 NFS

$ sudo apt-get install nfs-kernel-server

$ sudo apt-get install nfs-common

二配置 NFS (略过)

1 $ sudo dpkg-reconfigure portmap , 对Should portmap be bound to the loopback address? 选 N

2 $ sudo vi /etc/default/portmap 末行清除 "-i 127.0.0.1"

三配置 hosts.deny

$ sudo vi /etc/hosts.deny

文本末添加

### NFS DAEMONS

portmap: ALL

lockd: ALL

mountd: ALL

rquotad: ALL

statd: ALL

四配置 hosts.allow

$ sudo vi /etc/hosts.allow

文本末加入

### NFS DAEMONS

portmap: 192.168.1.

lockd: 192.168.1.

rquotad: 192.168.1.

mountd: 192.168.1.

statd: 192.168.1.

$ sudo /etc/init.d/portmap restart 重启portmap daemon.

显示如下

Since the script you are attempting to invoke has been converted to an

Upstart job, you may also use the restart(8) utility, e.g. restart portmap

portmap start/running, process XXXX

五配置 /etc/exports

$ sudo vi /etc/exports

文本末添加

/root/rootfs *(rw,sync,no_root_squash)

然后在终端执行 $chmod 777 -R /root/rootfs

$ sudo showmount -e

显示 clnt-create : RPC : Program not registered

$ sudo exportfs -r 更新

$ sudo showmount 192.168.1.116 -e

显示

Export list for 192.168.1.116

/root/rootfs *

六启用

$ sudo /etc/init.d/nfs-kernel-server restart 重启nfs 服务

显示如下

* Stopping NFS kernel daemon [ OK ]

* Unexporting directories for NFS kernel daemon... [ OK ]

* Exporting directories for NFS kernel daemon...

exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/home/work".

Assuming default behaviour ('no_subtree_check').

NOTE: this default has changed since nfs-utils version 1.0.x

* Starting NFS kernel daemon [ OK ]

挂载测试

$ mount -t nfs localhost:/root/rootfs /mnt

$ mount -t nfs -o nolock localhost:/root/rootfs /mnt

执行后，进入/mnt 目录中，如果可以看到 /root/rootfs中的内容，则说明 nfs搭建成功！

二、NFS（网络文件系统）的配置

    (1) 安装
     apt-get install nfs-kernel-server
     apt-get install portmap nfs-common

    (2)编辑配置文件 /etc/exports，添加一行
     /nfs   *.*(rw,sync,no_root_squash)

    (3)修改挂载点的属性
     chmod -R 0777 /nfs
    (4)重启nfs
     sudo /etc/init.d/nfs-kernel-server restart
     sudo /etc/init.d/portmap restart
    (5)在本机上测试
     showmount -e
     mount -t nfs 172.20.149.190:/nfs ./tmp
