Use Kickstart + Apache + Dhcp + Pxe to install the operating system unattended

Today in my class, my boss sent two old servers and asked my colleagues and I to install the system. There is no USB flash drive on hand, and a new optical drive is taken, and the optical drive is broken .. We thought of using kicskstart to install the system. Just a laptop, the real machine is RedHat6.2 (it is also feasible to create a virtual machine on a laptop). Let's start to provide services. Device: 1 laptop, 1 rack-mounted vintage server (although old, Xeon E5), 1 Red Hat system disc or ISO Image File System: RedHat6.2

We thought of using kicskstart to install the system. Just a laptop, the real machine is RedHat6.2 (it is also feasible to create a virtual machine on a laptop). Let's start to provide services.

Device: 1 laptop, 1 rack-mounted vintage server (although old, Xeon E5), 1 Red Hat system disc or ISO Image File

System: RedHat 6.2

The installation steps are as follows:

1) install Httpd:

Yum install-y httpd *

2) mount the Rhel6.x CD and copy all the content under the CD to/var/www/html:

Mount/dev/cdrom/media

Cp-rf/media/*/var/www/html

3) install tftp-server, start the tftp service, and start the xinetd process at the same time:

1. rps-ivh tftp-server-xxx.rpm

2. vim/etc/xinetd. d/tftp

# Default: off

# Description: The tftp server servers files using the trivial file transfer \

# Protocol. The tftp prorocol is often used to boot diskless \

# Workstations, download configuration files to network-aware printers ,\

# And to start the installation process for some operatiing systems.

Service tftp

{

Socket_type = dgram

Protocol = udp

Wait = yes

User = root

Server =/usr/sbin/in. tftpd

Server_args =-s/tftpboot

Disable = no # The value of disable is changed to no

Per_source = 11

CPIs = 100 2

Flags = IPV4

}

3. service xinetd restart

Enable the TFTP function and change YES to NO.

4) supports PXE startup.

Create a tftpboot folder, as shown below (if it already exists, you do not need to create a folder)

Mkdir/tftpboot (note: the tftp configuration file depends on the path of the above configuration file)

Copy the pxelinux.0 file to the tftpboot Folder:

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

Copy/image/pxeboot/initrd. img and vmlinux on the first Linux installation CD to/tftpboot /.

Cp/var/www/html/image/pxeboot/initrd. img/tftpboot

Cp/var/www/html/pxeboot/vmlinux/tftpboot

Copy the isolinux/*. msg on the first CD to the/tftpboot directory:

Cp/var/www/html/isolinux/*. msg/tftpboot

Create a new pxelinux. cfg directory in tftpboot as follows:

Mkidr pxelinux. cfg

Copy the isolinux. cfg file on the first installation CD to the pxelinux. cfg directory, and change the file to default:

Cd pxelinux. cfg

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

5) install the Dhcp service and modify the configuration:

Yum install-y dhcp

Copy it to the directory specified by the configuration template and rename it:

Cp/usr/share/doc/dhcp-x.0.1/dhcpd. conf. sample/etc/dhcpd. conf

Modify the configuration file and add a line: filename "/pxelinux.0"

[Root @ localhost isolinux] # vim/etc/dhcpd. conf

Ddns-update-style interim;

Ignore clinet-updates;

Next-server192.168.1.14; # PXE Server IP Address

Filename "/pxelinux.0 ";

...

...

Finally, start the DHCP service as follows:

Service dhcpd start

6) install Kickstart and configure KickStart

First, install the KickStart toolkit. The command is as follows:

Rpm-ivh system-config-kickstart-*. rpm

Configure kickstart in the Gnone environment. The command is as follows:

System-config-kickstart

7) Save to/var/www/html/ks. cfg

Reboot and pay attention to the red parameters in the default file.
