Abstract: In order to simplify the process of building the experimental teaching environment of the network programming course,and ensure the authenticity,flexibility and expansibility of the environment,a virtual experiment platform based on real environment is designed and implemented on the basis of Vagrant.This method reduces the various problems caused by the inconsistency of the development environment,simplifies the related configuration of the laboratory,facilitates the flexible deployment and configuration of the experimental teaching environment of the network programming course,is beneficial to the migration environment and ensures the character of the students' after-class environment and the teaching environment.
