PXE Install Linux Server

Recently encountered a problem, the company's internal server due to older, optical drive is broken, also does not support USB drive boot, so there is no way, can only use PXE to install the operating system. Many online tutorials, but not clear enough, I came down to write about my transfer process.

A. Installing A DHCP server

Yum install dhcpvim/etc/dhcp/dhcpd.conf# can directly copy my following configuration, modify the subnet to Ddns-update-style Interim;ignore Client-updates;allow    Booting;allow bootp;subnet 192.168.2.0 netmask 255.255.255.0 {range 192.168.2.250 192.168.2.253;    Option routers 192.168.2.1;    Option Subnet-mask 255.255.255.0;    Default-lease-time 21600;    Max-lease-time 43200;    Next-server 192.168.2.136; FileName "pxelinux.0";}

Note:

Next-server: The specified address is the server where you start the file, typically the TFTP server address.

Start DHCP server, if error, view/var/log/message

Chkconfig--add dhcpdservice dhcpd start

B. Installing the TFTP server

yum install tftp-server/etc/xinetd.d/tftp# Direct copy can be service tftp{         socket_type             =  dgram        protocol                 = udp         wait                     = yes        user                     = root         server                   = /usr/sbin/in.tftpd         server_args&nBsp;            = -s /var/lib/tftpboot         disable                  = no        per_ source              = 11         cps                      = 100 2         flags                    = ipv4}

Start

/etc/init.d/xinetd restart

C. Install any one of the http/nfs/ftp to store the ks.cfg and ISO image files.

I use HTTP

Yum install httpd/etc/init.d/httpd startchkconfig httpd on

D. Configuring the required files in TFTP

#引导文件yum  install syslinux cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot# kernel file, Hang the CD in the/mnt. cp /mnt/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpbootmkdir /var/lib/tftpboot/ pxelinux.cfgcp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/defaultvim /var/lib/ tftpboot/pxelinux.cfg/default# Modify the following to modify your server address.

E. Configuring Kickstart

#安装镜像位置mkdir  /var/www/html/dvdcp -r /mnt/*  /var/www/html/dvd# Configuring Kickstart Files yum  install system-config-kickstartcp /root/anaconda-ks.cfg /var/www/html/ks.cfg vi  ks.cfg# can directly copy the following files, note that the HTTP server is modified to its own. # install os instead of upgradeinstall# use network installationurl  --url= "Http://192.168.2.136/dvd" # root passwordrootpw --iscrypted $1$t8tzkp5c$ 0odx9swkdoyuzlixbku8r.# system authorization informationauth  --useshadow   --passalgo=sha512# use graphical installgraphicalfirstboot --disable# system  Keyboardkeyboard us# system languagelang en_us# selinux configurationselinux  --disabled# installation logging levellogging --level=info# reboot after  installationreboot# system timezonetimezone --isutc asia/shanghai# system bootloader configurationbootloader --location=mbr# partition clearing  Informationclearpart --all%packages@base%end

F. End of configuration, you can find a motherboard with PXE function test can be.

As far as I know, most of the current PCs are supported.
