The company launches a business system, fully automated one-click installation system script sharing

1. Background description:

The company recently needed to launch several business systems and purchased 11 HP servers. Engineers from the manufacturer helped install the servers, and the system was not installed, so we had to install it ourselves.

Think about the Linux shutdown command, the environment in the computer room~it’s so cold! Therefore, we must not automatically install each one How to install a linux system, so I compiled a fully manual one-click installation system script. I tested it on both RedHat and centos7, and the verification results were successful. Specifically Please see the process below!

The overall process of one-click manual installation script is as follows:

The client starts from the network card and manually obtains the IP address from the DHCP server in the external network; manually obtains the url of the boot file; the DHCP server returns the client IP and the url of the bootstrap file; the client obtains it from the TFTP server in the external network bootstrap file and execute it; load the kernel and file system through the TFTP server to start the installation. The manual installation is completed and the system restarts!

3. For server-side installation and configuration, you only need to execute this script, as shown in the picture on the right:

Manually install and configure DHCP, TFTP, xinetd, Vsftpd, syslinux, Tcpdump and other services, as shown in the picture on the right:

4. The client manually starts installing the system

On the client side, I am using a virtual machine for demonstration. I configure the virtual machine to enable heavy network card startup, as shown in the picture on the right:

이걸로 Linux 읽는 방법을 마치겠습니다. 지난 호에서는 전체 작동 과정을 자세히 영상으로 보여드리겠습니다.
