Centeros environment setup

In daily work, many students' intranet working environment is not allowed to connect to the Internet , When you need to build an intranet development environment, you always need to download the required packages in the external network environment and install them on the intranet . At this time, if the environment of the intranet and the Internet is different, the files copied into the intranet may be unusable or prone to bug. Therefore, we need to pull packages on the Internet according to the environment version of the intranet . This article mainly introduces how to build the same virtual machine system as the intranet on the extranet , And pull the required file package from the Internet , Copy to intranet for environment construction .

Check the intranet linux Version of environment
