Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The embodiment of the present invention discloses a method and system for installing LINUX systems in batches based on PXE technology, so as to realize efficient installation of operating systems.

Referring to Fig. 1, a kind of method based on PXE technology batch installation LINUX system that the embodiment of the present invention provides, comprises:

S101, selecting a target server on which the LINUX system has been installed;

S102. Install preset services to the target server, and add a boot image and configuration file to generate a PXE server, so that the local computer downloads the installation image and configuration file from the PXE server, and automatically installs it through the installation image and configuration file Linux system.

Wherein, installing preset services to the target server includes:

Install and configure DNSMASQ service, TFTP-Server service and VSFTPD service to the target server, and configure SYSLINUX loading initiator to the target server. Wherein, when configuring the DNSMASQ service to the target server, the IP address in the configuration is changed to the IP address of the local area network.

Wherein, the adding boot image and configuration file includes:

Add the CentOS 7 boot image to the target server, and create a local image installation source for CentOS 7; use the ks.cfg file automatically generated by the target server as a configuration file, and modify the installation media of the ks.cfg file.

Specifically, this embodiment provides a specific embodiment, assuming that there are several computers A, B, C...,

Step 1: Use the general method of installing the system (U disk, CD, etc.) to install the system for computer A. This article uses U disk to install centos7 as an example, and computer A will be used as a PXE server to provide a server environment for other computers;

Step 2: Install and configure DNSMASQ, TFTP-Server, VSFTPD and other services;

1) Configure DNSMASQ: vim/etc/dnsmasq.conf:

interface＝eno16777736,lo #The network interface that server A needs to monitor and provide services.

#bind-interfaces

domain=inspur #Domain name of server A

#DHCP range-leases

dhcp-range=eno16777736,192.168.37.2,192.168.37.253,255.255.255.0,1h

tftp-root=/var/lib/tftpboot

Specifically, the IP address in this configuration is replaced with the IP of the local area network, and DNSMASQ provides DHCP and DNS services for the local area network.

2) Configure SYSLINUX to load the launcher:

cp -r /usr/share/syslinux/*/var/lib/tftpboot;

3) Configure the PXE server: vim/var/lib/tftpboot/pxelinux.cfg/default:

default menu.c32

prompt 0

timeout 300

ONTIMEOUT local

menu title##########PXE Boot Menu##########

label 1

kernel centos7/vmlinuz

append initrd=centos7/initrd.img ks=ftp://192.168.37.134/pub/ks.cfg

devfs=nomount

Step 3: Add CentOS 7 boot image to PXE server

Mount the U disk mount-o loop-t/dev/cdrom/mnt, if there is no U disk, you can also use the ISO image mount-o loop-t iso9660path/centos-dvd.iso/mnt:

mkdir /var/lib/tftpboot/centos7

cp /mnt/images/pxeboot/vmlinuz/var/lib/tftpboot/centos7

cp /mnt/images/pxeboot/initrd.img/var/lib/tftpboot/centos7

Step 4: Create a CentOS 7 local image installation source:

cp -a /mnt/./var/ftp/pub/

Step 5: Add unattended ks.cfg configuration file

In this embodiment, the aconda-ks.cfg file automatically generated after computer A is installed is used as an unattended configuration, so the operating system environment installed using it is exactly the same as that of computer A:

cp～/anaconda-ks.cfg/var/ftp/pub/ks.cfg

chmod -R 755 /var/ftp/pub

Modify the ks.cfg file, and change the installation media from cdrom to url--urlftp://192.168.37.134/pub/. Now the PXE server configuration is complete.

Start the DNSMASQ and VSFTPD servers:

systemctl start dnsmasq;

systemctl start vsftpd;

DNSMASQ and VSFTPD services are configured to start on boot:

systemctl enable dnsmasq;

systemctl enable vsftpd;

Close the firewall service and disable SELINUX, test the FTP installation source, and finally, unmount the CentOS 7DVD and remove the physical media.

Step 6: Configure the client to boot from the network:

Computers such as computer B and computer C that need to install the system are set to boot from the network through the system BIOS. When the PXE prompt appears for the first time, please press the F8 key to enter the PXE installation interface, and then press the Enter key to continue entering the PXE menu. , press Enter to enter the automatic installation process.

Specifically, this solution uses the PXE technology developed by Intel Corporation to download the image from the remote server through the local computer through the network, and thus supports the startup of the operating system through the network. During the startup process, the terminal requires the server to assign an IP address, and then uses TFTP to Or the MTFTP protocol downloads a startup software package to the local memory for execution, and the startup software package completes the terminal basic software settings, thereby booting the terminal operating system pre-installed in the server. Moreover, this solution combines the KICKSTART unattended installation method to realize the batch installation of LINUX systems in the LAN, so that the server environment can be quickly arranged, and a lot of time is saved for installing operating systems on a large number of computers. The automated installation process makes the system installation easier. It's very simple.
