Linux NFS Introduction

Developed by Sun, used between different systems, so its design is not related to the host system, users want to use remote files, only need mount–t NFS can take the remote files to local, like the use of local files, very convenient.

It uses a C/s architecture that uses RPC and XDR (external data representations) to exchange data between different computers.

When you start the NFS file server,/etc/rc.local automatically launches the EXPORTFS program, specifying the files or directories that can be exported, and of course you can start them yourself.

sudo exportfs–rv

Installing NFS

The server configuration requires editing the/etc/exports. config file, which lists the directories that the server wants to share with the outside.

Dir IP (rules)
