The server installs the system in batch to the workstation.

Through PXE (pre-boot execution environment, booting through the network card, the network card must support PXE technology) technology, the workstation can download the image from the remote server, and thus support booting the operating system through the network. During the startup process, the terminal requires the server to assign an IP address, and then uses the TFTP (trivial file transfer protocol) protocol to download a startup software package to the local memory for execution.

To use the kickstart installation platform, the full architecture is kickstart+DHCP+NFS+TFTP+PXE

Yum install-y dhcp* tftp*

Tftp is a non-independent startup process that relies on other software and / etc/init.d/xinted. This xinet is dedicated to managing non-independent startup services.

Configure TFTP

Modify / etc/xinetd.d/tftp to change disable to no

Server_args =-s / var/lib/tftpboot in the file is the file storage directory

/ etc/init.d/xinetd start

Link / var/lib/tftpboot to the root directory

Ln-s / var/lib/tftpboot /

Cd / tftpboot/

Server is equipped with PXE

To find the file pxelinux.0

Yum install-y syslinux syslinux-devel

Cp / usr/share/syslinux/pxelinux.0 / tftpboot/

Mount the CD and copy it to / data

Mkdir-p / data/centosinstall/

Mount / dev/cdrom / data/centosinstall/

Cp-a / mnt/* / data/centosinstall/

The following two files open the opportunity to find

Cp / data/centosinstall/p_w_picpaths/pxeboot/vmlinuz / tftpboot/

Cp / data/centosinstall/p_w_picpaths/pxeboot/initrd.img / tftpboot/

Configure a boot menu

Mkdir / tftpboot/pxelinux.cfg

Copy menu boot file

Cp / data/centosinstall/isolinux/isolinux.cfg / tftpboot/pxelinux.cfg/default

Vim / tftpboot/pxelinux.cfg/default write

Append-

The second part is the meaning of loading kernel.

Ks=nfs means to find the file shared remotely after the kernel is loaded; ksdevice specifies which network card starts to install the system.

The first part of F1 to F5 can not be, because the top and bottom are Linux, boot directly automatically load the kernel.

Share this image with NFS

Echo "/ data/centosinstall/ * (ro,sync,insecure,no_root_squash)" > > / etc/exports

/ etc/init.d/nfs restart

After TFTP is configured, since TFTP is a non-independent service, you need to rely on xinetd service to start it. The startup command is as follows:

Chkconfig tftp-- level 35 on & & service xinetd restart

Then create ks.cfg under / data/centosinstall/, this file is equipped with what system, how to partition, which software, or / root/anaconda-ks.cfg cp into ks.cfg, this is the local installation of the system step, this file should be used by the teacher

Touch / data/centosinstall/ks.cfg

Cat > / data/centosinstall/ks.cfg
