PXE automatic installation

PXE Automatic installation method

1. Install the base component package

Ensure that you have installed the operating system, and as a PXE Server, we recommend using the latest version of Rhel 6.

1. Create a Yum installation source.

Cat>>/etc/yum.repos.d/rhel-dvd.repo<<!
[Rhel-dvd]
name=red Hat Enterprise Linux DVD
Baseurl=file:///media/rhel6-dvd
Enabled=1
Gpgcheck=0
!

You need to make sure that the CD is mounted to the/media/rhel6-dvd directory. As follows:

# Mkdir/media/rhel6-dvd

# Mount–o Loop/dev/sr0/media/rhel6-dvd

1. Install the required component packages

yum-y Install DHCP Tftp-server syslinux httpd

1. Configure the underlying service
   1. Configuring DHCP and TFTP services

# cat >>/etc/dhcp/dhcpd.conf <<!
Option Domain-name "pxe.com";
Option Domain-name-servers 192.168.157.254;
Option routers 192.168.157.254;
Default-lease-time 14400;

range 192.168.157.10 192.168.157.100;
Default-lease-time 14400;

}
########## Assigning a client to a specified IP ###############################
Host Liujia {
Hardware Ethernet 00:0c:29:e5:c5:28;

}
#############################################################

Note: You need to make sure you are currently using DHCP distribution of the network card, set the above configured IP, 192.168.157.254

1. Start the service, add boot auto-start

Chkconfig TFTP on

/etc/init.d/xinetd start

Chkconfig DHCPD on

/ETC/INIT.D/DHCPD start

Chkconfig httpd on

/ETC/INIT.D/HTTPD start

1. Create an install HTTP installation source directory

# cd/var/www/html/

# mkdir Wwwrepo ks

# cp–r/media/rhel6-dvd/* Wwwrepo

1. Create a PXE component directory schema

[Email protected]]# pwd

/var/lib/tftpboot

[Email protected]]# tree.

Summary of issues

1. Dell only has one first NIC that starts PXE by default

You need to modify the network card in your actual environment to configure it. Enter the NIC configuration interface to configure.

1. When there are multiple NICs, the installation interface stops on the NIC selection

To modify the PXE menu boot configuration, add a similar following:
