Pxe+kickstart+apach+dhcp+tftp for unattended installation, centos6.5

Objective: To implement unattended installation

Environment: centos6.5

Components: Default Pxe,kickstart, Apache, TFTP, DHCP

PXE:PXE (Pre-Boot execution Environment, pre-boot execution Environment)

• is a boot mode, the network card must have the PXE CLIENT,PXE protocol to enable the computer to boot over the network. This protocol is divided into the client side and Server side, while the PXE client is in the ROM of the network card, when the computer boots, the BIOS will put the PXE client into memory execution, and then by the PXE client to be placed on the remote file over the network download to run locally, so run PXE protocol needs to set up DHCP server and TFTP server

Kickstart

• An unattended installation, you can generate a custom answer parameter file Ks.cfg, when the installation, encountered the need for human action, the installer will go to view the Ks.cfg file, automatic response according to the settings inside, to automate the installation, and automatically restart according to the parameters

Steps

1:centos6.5 installation httpd

2: after mounting, copy the contents of the disc to the root directory of HTTP/var/www/html/

• Cp-r/mnt/cdrom/var/www/html

3: Install TFTP

4: Configure and turn on services

• /ETC/XINETD.D/TFTP configuration file

• Open service: (TFTP belongs to Super Demon)/etc/init.d/xinetd start

5: Set up PXE-enabled boot program

• Copy the pxelinux.0 file into the/var/lib/tftpboot/directory

cp/usr/share/syslinux/pxelinux.0/var/lib/tftpboot/#Syslinux is a powerful bootloader and compatible with a variety of media

• Copy the/image/pxeboot/initrd.img and vmlinux in the ISO image to the/var/lib/tftpboot/ directory

Cp/var/www/html/cdrom/images/pxeboot/{initrd.img,vmlinuz}/var/lib/tftpboot/

• Copy the/isolinux/*.msg in the ISO image to the/var/lib/tftpboot/ directory

cp/var/www/html/cdrom/isolinux/*.msg/var/lib/tftpboot/

• Create a new pxelinux.cfg directory in/var/lib/tftpboot/

mkdir/var/lib/tftpboot/pxelinux.cfg

• Copy isolinux.cfg from the/isolinux directory in the ISO image to the PXELINUX.CFG directory and change the file name to default

Cp/var/www/html/cdrom/isolinux/isolinux.cfg/var/lib/tftpboot/pxelinux.cfg/default

6: Modify the default file

• /var/lib/tftpboot/pxelinux.cfg/default

8: Modify DHCP configuration file

• Copy the configuration template file into the DHCP configuration directory

Cp/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample/etc/dhcp/dhcpd.conf

• Modify the/etc/dhcp/dhcpd.conf configuration file with the following content:

• Start the DHCP service

9: Generate KS.CF file with Kickstat

• Installation: Yum Install System-config-kickstart

• Startup and Configuration: System-config-kickstart

• Graphical interface Configuration: Example of the end of the article

• The saved files are:/var/www/html/ks.cfg

haha And then I silently installed three more virtual machines.

10: Automatic installation, network type should choose NAT
