How to setup NFS in Ubuntu

How to setup NFS in Ubuntu

1. install nfs

$sudo apt-get install nfs-kernel-server

2. check hosts name

$hostname --fqdn

ex:

$hostname --fqdn usernamehost

The host name could not have special character, like "-, _, ", only "usernamehost". if return error, modify the host name, log-out then log-in.

$sudo vim /etc/hosts 127.0.1.1 kelseylaiAS5551 … ….

3. setup nfs

$vim /etc/hosts.allow

portmap: [tv_ip]

lockd: [tv_ip]

rquotad: [tv_ip]

mountd: [tv_ip]

statd: [tv_ip]

ex:

$sudo vim /etc/hosts.allow ... portmap: 192.168.0.107 lockd: 192.168.0.107 rquotad: 192.168.0.107 mountd: 192.168.0.107 statd: 192.168.0.107 …

/etc/hosts.deny 和 /etc/hosts.allow 設定對portmap的訪問. 採用這兩個配置檔案有點類似黑名單，白名單的意思. 先在/etc/hosts.deny中禁止所有用 戶對portmap的訪問.再在/etc/hosts.allow 中允許某些特殊用戶對portmap的訪問。

4. modify NFS directory permission

$sudo vim /etc/exports … /home/NFS 192.168.0.*(rw,sync,no_root_squash) … $exportfs -r

NFS掛載目錄及權限由/etc/exports檔案定義

例如，我在家目錄下建立一個名為NFS的目錄，作為共享給板子的，則在該檔案裡加入

/home/NFS/192.168.0.*(rw,sync,no_root_squash)

5. make direcotry for NFS

$mkdir [you_want_nfs_path]

ex:

$sudo mkdir /home/NFS

   6. restart nfs server

$sudo service nfs-kernel-server restart
