Unattended automated installation of the RHEL 5.5 operating system using Kickstart, DCHP, TFTP, and HTTP

//
Unattended automated installation of the RHEL 5.5 operating system using Kickstart, DCHP, TFTP, and HTTP
Server ip:192.168.10.178 Operating system: Red Hat Enterprise Linux Server release 5.5
//
The steps are as follows:

1. Installing and configuring the DHCP service
1.1 Use the following command to check whether DHCP is installed, RHEL5 system default installation Dhcp-3.0.5-23.el5
[Email protected] ~]# Rpm-qa | grep DHCP
If the system does not have DHCP service installed, first install the following RPM package:
dhcp-3.0.5-23.el5.i386.rpm

1.2 Configuring DHCP, modifying/etc/dhcpd.conf
[Email protected] ~]# vi/etc/dhcpd.conf

Examples of #dhcpd. conf configuration files:
#
# DHCP Server Configuration file.
# See/usr/share/doc/dhcp*/dhcpd.conf.sample
#
Ddns-update-style Interim;
Ignore client-updates;
Allow booting;
Allow BOOTP;

FileName "pxelinux.0"; #pxelinux Loader file location
Next-server 192.168.10.178; #tftp所在服务器ip, my serverip.

Subnet 192.168.10.0 netmask 255.255.255.0
{
Option routers 192.168.10.1;
Option Subnet-mask 255.255.255.0;
Range DYNAMIC-BOOTP 192.168.10.100 192.168.10.110; #dhcp动态提供的ip地址范围
Default-lease-time 21600;
Max-lease-time 43200;
}
1.3 After modifying the configuration, restart the service
[[email protected] ~]#/ETC/INIT.D/DHCPD start# start
[[email protected] ~]#/ETC/INIT.D/DHCPD restart# restart

2. Installing and enabling the TFTP service
2.1 Verify that the TFTP service is installed and, if none, install it first.
[Email protected] ~]# Rpm-qa | grep tftp
If TFTP is not installed, first install the following two RPM packages:
tftp-0.49-2.i386.rpm
tftp-server-0.49-2.i386.rpm

2.2 After installing TFTP, modify the configuration file to enable the service
[Email protected] ~]# vi/etc/xinetd.d/tftp

#例子:
# Default:off
# description:the TFTP server serves files using the trivial file transfer \
# protocol. The TFTP protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to-start the installation process for some operating systems.
Service TFTP
{
Socket_type = Dgram
protocol = UDP
Wait = yes
user = root
Server =/USR/SBIN/IN.TFTPD
Server_args =-s/tftpboot
Disable = no# default is yes, here to No
Per_source = 11
CPS = 100 2
Flags = IPV4
}

2.3 After modifying the configuration, restart the service
[[email protected] ~]#/etc/init.d/xinetd start# start
[[email protected] ~]#/etc/init.d/xinetd restart# restart

3. Install and start the HTTP service
3.1 Verify that the HTTP service is installed and, if none, install the service first.
[Email protected] ~]# Rpm-qa | grep http

If there are no HTTP packets in the returned results, install the following RPM packages:
httpd-2.2.3-43.el5.i386.rpm

3.2 After the installation is complete, restart the service
[[email protected] ~]#/etc/init.d/httpd start# start
[[email protected] ~]#/etc/init.d/httpd restart# restart

4. Mount the system image
4.1 Place the RHEL5.5 disc image Rhel-server-5.5-i386-dvd.iso in the server, such as the/home directory.

4.2 Mount ISO image to a directory, such as the/media/rhel5_iso directory
[[email protected] ~]# mkdir/media/rhel5_iso# Create mount directory
[email& Nbsp;protected] ~]# mount-t iso9660-o loop/home/rhel-server-5.5-i386-dvd.iso/media/rhel5_iso

4.3 Use HTTP to provide security Install the source file
under HTTP directory/var/www/html/to create a link to hang in directory/media/rhel5_iso
[[email protected] ~]# ln-s/media/rhel5_iso/var/ www/html/rhel5# Create a link
or
Create a folder under HTTP directory/var/www/html/and mount the image to that folder
[[email protected] ~]# mkdir/var/ www/html/rhel5.5
[[email protected] ~]# mount-t iso9660-o loop/home/rhel-server-5.5-i386-dvd.iso/var/www/ HTML/RHEL5.5/

5. Configure the system boot file
5.1 RHEL5 is the default installation syslinux, copy/usr/lib/syslinux/pxelinux.0 to/tftpboot/directory
[[ Email protected] ~]# cp/usr/lib/syslinux/pxelinux.0/tftpboot/

5.2 Copy the Initrd.img,vmlinuz,isolinux.cfg file from the system installation image/media/rhel5_iso/isolinux directory to the/tftpboot/directory
The Initrd.img,vmlinuz in the above file is also present in the #在/media/rhel5_iso/images/pxeboot directory
[Email protected] ~]# cp/media/rhel5_iso/isolinux/initrd.img/tftpboot/
[Email protected] ~]# cp/media/rhel5_iso/isolinux/vmlinuz/tftpboot/
[Email protected] ~]# cp/media/rhel5_iso/isolinux/isolinux.cfg/tftpboot/

5.3 Create folder Pxelinux.cfg under/tftpboot/directory, move isolinux.cfg into pxelinux.cfg directory and rename to default
[Email protected] ~]# mkdir/tftpboot/pxelinux.cfg
[Email protected] ~]# Mv/tftpboot/isolinux.cfg/tftpboot/pxelinux.cfg/default
[Email protected] ~]# chmod 777/tftpboot/pxelinux.cfg/default

5.4 Edit Modify/tftpboot/pxelinux.cfg/default file
[Email protected] pxelinux.cfg]# Vi/tftpboot/pxelinux.cfg/default

6. Kickstart configuration, configuration file is Ks.cfg
#kickstart是Red Hat provides an installation method that allows you to automate most of the installation tasks for Red Hat Linux.
#kickstart的配置文件ks. CFG is a text file that can be created by using the Kickstart Configurator, or by writing one manually, or by using the/root/anaconda-ks.cfg file to make changes
#关于kickstart选项可参照: http://man.ddvip.com/os/redhat9.0cut/s1-kickstart2-options.html
#
#将ks the. cfg file to the HTTP directory
[Email protected] ~]# MV ks.cfg/var/www/html/

An example of #ks. cfg file is the ks.cfg file used when installing rhel5.5
# Kickstart file automatically generated by Anaconda.
