One-click installation of Linux (with a variety of commands, login welcome interface, user login module .)

Based on the integration we made a few days ago, we finally wrote a one-click Linux script. This is really a key, with common commands, as well as the welcome interface, plus a prompt and so on.

Join the network module tomorrow to make it accessible to the internet!

 

HOST: RedHat Enterprise 5 (2.6.18)

Target machine: 256 memory, 8 GB hard disk.
