Building pxelinux in RHEL6.3

First, let's take a look at the services required for the production of pxe. linux:

DHCP, tftp, and pxelinux files,

First, set up a DHCP server.

Install the tftp package as follows:Tftp-server.i686

During installation, the processes and services of the tftp package are related to the xtend service:

Enable the tftp service under xinted:

Switch to the xinted service cd/etc/xinetd. d/

Edit the tftp service configuration file vim tftp

Disable = no // enable the tftp service

Use rpm-ql tftp-server to find the path of the tftp configuration file:

/Var/lib/tftpboot

Since pxelinux.0 is a built-in system command, we use:

# Yum whatprovides */pxelinux.0 // find the installation package of pxelinux.0 and the file path.

Installation Package: # yum install syslinux-4.02-7.el6.i686-y

When the system is started, the read pxelinux.0 is in the tftp directory and is not in the/usr/share/syslinux directory at all, right?

 

We know where the blue image of the startup system and the title file are stored?

First mount the image:

Add the image to the virtual machine configuration and mount it with mount.

 

 

Switch to the/mnt/isolinux directory. Note: vmlinuz, initrd. img, and isolinux. cfg are available in the same version. Otherwise, the experiment may fail.

All we need to do is to cp all the files in this directory to/var/lib/tftpboot:

[Root @ redhat isolinux] # cp-a./*/var/lib/tftpboot/

[Root @ redhat tftpboot] # ls

Boot. cat grub. conf isolinux. bin memtest splash.jpg vesamenu. c32

Boot. msg initrd. img isolinux. cfgPxelinux.0TRANS. TBL vmlinuz

The original tftp directory only hasPxelinux.0File, right.

Create a directory pxelinux. cfg, The following are all fixed formats, official website pxelinux.0The manual is written in this way.

Modify defaule.File to add the following lines to it:

 

Label linux

Menu label ^ Install hello world //Added a hello worldTitle

Menu default

Kernel vmlinuz

Append initrd = initrd. img

 

 

Configure dhcpService:

Add only the following 2Line, next-server 192.168.7.3; filename "pxelinux.0 ";

 

Restart DHCPService:

[Root @ redhat tftpboot] #/etc/init. d/dhcpd restart

Shutting down dhcpd: [OK]

Starting dhcpd: [OK]

 

Client test:

First, unplug the network cable and use your own DHCPService:

Restart the network:If unplugging is not performed, local DHCP is not used.Service.

 

Ip addressChange to dynamic retrieval:In this way, local DHCP can be obtained.Service ip Address

 

Start from network instead:The following error is reported:

 

 

This is because selinux = enforcingWe setenforce = 0OKNow

 

OK will be found when you start againOf:

It can also be written like this: with kisckstartOne use:
