Linux File Share NFS

The Experiment centos6.5

192.168.204.150 nfs150

192.168.204.128 Client

Experiment starts, still shuts down the firewall, turns off SELinux

Do you remember the order?

#/etc/init.d/iptables Stop

# chkconfig Iptables off

# Vim/etc/selinux/config

Modify to Selinux=disabled

# Setenforce 0 Immediate effect

The NFS (Network File system), which is one of the file systems supported by FreeBSD, allows computers in the network to share resources across TCP/IP networks. In an NFS application, a local NFS client application can transparently read and write to files located on the remote NFS server, just as you would access a local file.

"NFS 150" server-side NFS

Yum Install nfs*-y

# Mkdir/webdata
NFS installation complete, need to create a shared directory, shared directory in the/etc/exports file configuration

/webdata/* (Rw,sync,no_root_squash)

parameter of the note at the tail, thank you

And then we can start NFS.

#/etc/init.d/rpcbind Start # Please start Rpcbind or you'll get an error.

# Chkconfig Rpcbind on

#/etc/init.d/nfs Start

# Chkconfig NFS On

Client

Can create a new folder

# Mkdir/webdata

And then execute

# mount-t NFS 192.168.204.150:/webdata/webdata

Congratulations, no success!

Now you need a new installation package

# yum Install Nfs-utils-y

Oh, depends on the package is really a lot, all installed

You can perform

# showmount-e 192.168.204.150 # View 150 What is the shared directory of the machine?

Execute again

# mount-t NFS 192.168.204.150:/webdata/webdata

# Cd/webdata

# ls

Yes, just like your local hard drive, as long as you have permission, you can do whatever you want.

Important, if you want to restart the machine every time, automatically mount, please modify the/etc/rc.local file, add mount command

Mount-t NFS 192.168.204.150:/webdata/webdata

Instead of not modifying/etc/fstab

Configuration file parameter explanation:

/webdata shared Directory

* On behalf of all IP can be accessed

RO: The host has read-only access to the shared directory

RW: This host has read and write access to the shared directory

Root_squash: When the client accesses the shared folder with the root user, the root user is mapped to an anonymous user

No_root_squash: When the client accesses the shared folder with root, the root user is not mapped

All_squash: Mapped to anonymous user when any user on the client accesses the shared directory

Anonuid: A user who maps a user on a client computer to a specified local user ID

Anongid: Maps the user on the client computer to the specified local user group ID

Sync: Data synchronously written to memory and hard disk

Async: Data is staged in memory, not directly to the hard disk

As long as the direction of the progress of every day, will always reach the distance you want!!!
