A simple shell script-----Implement a simple configuration of the virtual machine lab environment

Personally wrote the shell script only to find that this thing is very convenient, when you want to put some trivial, detailed small instructions to complete a single time, the script is undoubtedly the best choice, convenient, fast, the key is really lazy people must ah.

Since the installation of the centos6.5 is minimized and is an experimental environment, which is installed on the VMware workstations, after the first installation is complete, the information about the IP address is configured and an initial snapshot is made so that the system can be quickly restored with a snapshot after the next experiment.

However, due to the requirements of the experimental environment, such as firewall, SELinux, CD mount, yum source configuration, etc., are the most commonly needed to modify the options, and because of the minimal installation, the system does not have the VIM compiler tool and the man manual query, so after each restore snapshot, but also to deal with these trivial issues. To this end, I have specifically written a small script, the content is not complex, but it is a learning process, sent to share with you, by the way advice ...
