How to build nfs service on ubuntu16.04

Introduction to NFS

NFS (Network File System) is a network file system, one of the file systems supported by FreeBSD, which allows computers on the network to share resources through a TCP/IP network. In NFS applications, local NFS client applications can transparently read and write files located on remote NFS servers, just like accessing local files.

The nfs service is to realize file sharing between Linux and Linux, and the construction of the nfs service is relatively simple.

Now introduce how to build nfs service in ubuntu16.04 system, ubuntu is easier to build than Red Hat.

How to configure NFS on Ubuntu

  192.168.1.12 Only this user can mount(ro,sync,no_root_squash): Permission
 ro :Read only
 rw :Read and write
 sync :Synchronize
 no_root_squash:Does not reduce the permissions of the root user
