Ubuntu 12.04 LTS nfs-util 安装及配置手记

开始之前，我们要了解目的【Ubuntu下搭载nfs服务器】- 这个目的所引用的文章更具参考性，下文只是手段之一。

Ubuntu 12.04 LTS nfs-util 安装及配置手记
Note for Installing nfs-util on Ubuntu 12.04 LTS

写在前面：you have to know first:
【Client端install the nfs-common package. Server端install nfs-kernel-server】
is recommended.


1. Intall nfs-kernel-server:
   $ apt-get install nfs-kernel-server


2. Create a folder:
   $ mkdir -p /opt/share


3. Change Permission:
   $ chmod -R 777 /opt/share

4. Configure /etc/exports:
   $ sudo chmod a+w /etc/exports   #change "read only" into writeable.

   opt/share 10.112.18.0/255.255.255.0(rw,no_root_squash)


5. Configure /etc/hosts.allow:
   portmap:10.112.18.0/255.255.255.0


6. Configure /etc/hosts.deny:
   portmap:ALL


7. Restart two services:
   service portmap restart
   service nfs-kernel-server restart
-----
8. Insatll nfs-common on another Ubuntu:
   apt-get install nfs-common


9. Create new folder:
   mkdir ~/test


然后运行测试命令看一下：


# showmount -e 10.112.18.158 


Export list for 10.112.18.158: 


/opt/share 10.112.18.0/255.255.255.0 


找到nfs server的挂载目录了。现在手工挂载：


mount -t nfs4 10.112.18.158:/opt/share ~/test/ 

现在可以测试了，应该成功。

• 在实验中可暂时关闭NFS服务器主机中的iptables网络防火墙服务

      # service iptablesstop

=======================  执意安装 nfs-utils ====================

1. 检查本机是否安装nfs-utils
   Check if the nfs-utils has been installed on Linux


Command:
$ rpm -q nfs-utils


We get:(if nfs-utils is not installed)
$ rpm -q nfs-utils
package nfs-utils is not installed


2. 下载nfs-utils安装包
   Download nfs-utils Installation package


   Google: nfs-utils, 
we find nfs-utils-1.2.9.tar.bz2 at:
http://sourceforge.net/projects/nfs/
   Download it to ~/Download
----------------------------------------------------
$cd ~/Download
$tar -jxvf nfs-utils-1.2.9.tar.bz2 // unpack it
$cd nfs-utils-1.2.9 // enter this folder

$cat readme //open and read the readme file
----------------------------------------------------
   We can see there are instructions, and we notice:
--------------------
1. COMPILING


Unpack the sources and run these commands:


    # ./configure
    # make


To install binaries and documenation, run this command:

we met an error and gave it up.. :(
