Set up an NFS Network File System server in CentOST6.6

1. NFS Introduction

   Network File System (NFS) allows computers on the Network to share resources over TCP/IP networks. In NFS applications, local NFS client applications can transparently read and write files on the remote NFS server, just like accessing local files.

   NFS can save local storage space and share some storage devices such as soft drives, CDROM, and Zip. The difference between NFS and Samba is that Samba is generally cross-platform, NFS is easy to use between unix-like systems,

2. NFS installation and configuration

   Major software packages:

   NFS depends on the rpc-bind package. The main installation packages are nfs-utils and rpcbind;

   System Service script

   /Etc/init. d. nfs

   /Etc/init. d/rpcbind

   Main configuration file

   /Etc/exports

   This configuration file determines the NFS shared directory, IP address or network segment, domain, read/write permission, and whether to retain the root permission from the client. For file configuration, see man 5 exports

   EXAMPLE

   # Sample/etc/exports file

   /Master (rw) trusty (rw, no_root_squash)

   /Projects proj *. local. domain (rw)

   /Usr *. local. domain (ro) @ trusted (rw)

   /Home/joe pc001 (rw, all_squash, anonuid = 150, anongid = 100)

   /Pub * (ro, insecure, all_squash)

   /Srv/www-sync, rw server @ trusted @ external (ro)

   /Foo 2001: db8: 9: e54:/64 (rw) 192.0.2.0/24 (rw)

   /Build buildhost [0-9]. local. domain (rw)

   /Etc/default/portmap

   This configuration file is responsible for the rpc port mapped to NFS;

   /Etc/hosts. deny

   This configuration file determines which IP Lists cannot be accessed;

   /Etc/hosts. allow

   This configuration file determines which IP lists can be accessed;

   Main commands

   Showmount e server address

1. Software installation and configuration

   Software Installation

[Root @ woonx64 ~] # Rpm-qa nfs-utils rpcbind

Rpcbind-0.2.0-11.el6.x86_64

Nfs-utils-1.2.3-54.el6.x86_64

If Not Installed

Yum y install nfs-utils rpcbind

Configure sharing

[Root @ woonx64 Study] # vim/etc/exports

/Study 192.168.239.128 (rw, no_root_squash)

#/Usr/src woon (rw, no_root_squash)

Restart service

View shared information

[Root @ woonx64 Study] # showmount-e 192.168.239.129

Export list for 192.168.239.129:

/Study 192.168.239.128

[Root @ woonx64 Study] #

Mount the nfs shared directory

[Root @ woon ~] # Cd/

[Root @ woon/] # mkdir/nfs

At this time, it cannot be mounted because my/Study is an ntfs partition mounted on the server through the samba service, which may not be supported. Replace it with/root to restart the service and mount it.

[Root @ woon/] #! Show

Showmount-e 192.168.239.129

Export list for 192.168.239.129:

/Root 192.168.239.128

[Root @ woon/] # mount-t nfs 192.168.239.129:/root/nfs/

[Root @ woon/] # cd nfs/

[Root @ woon nfs] # ls
