CentOS 6.5 system customization and encapsulation quick implementation script

Users who work in O & M for large enterprises or IDCs often have such requirements. Some people may not be very familiar with the advantages of Linux's secondary encapsulation, that is, when you need to perform one operation repeatedly, for example, to deploy 300 WEB servers, if you want to install one server, and then configure the WEB application after installing the system, how long does it take! However, if you have installed a server and then encapsulated the system twice, you will need to deploy the same WEB server with the encapsulated system next time, this is much simpler. At this time, some people may doubt whether there will be any driver problems. Of course, the system itself is OK. It is OK unless you are a special hardware. In fact, a simple understanding is that a windows ghost package is similar. If you still don't quite understand it, you may need to read the text several more times. I have tested some online tutorials in the early stage and found that CentOS6.0 and above are not very easy to use. Due to time reasons, I only paste the encapsulated shell here, in fact, there still needs to be a complicated process. You may need to carefully understand the shell in the kernel. If you need it, contact me. Of course, I often use it to encapsulate servers such as openvpn, vsftpd, and web, so that it can be fully automated and quickly deployed to improve my work efficiency, we will have the opportunity to share with you the encapsulation package of the last vsftpd server! The header is bleeding.
