PXE + Kickstart Unattended Automatic installation example

System version: CentOS 6.5 vsftpd software version: vsftpd-2.2.2-11 TFTP software version: tftp-server-0.49.7 DHCP software version: dhcp-4.1.1-38 System-config-kicksta RT Tool Version: System-config-kickstart-2.8.6.5-1

PXE is a network boot technology, operating mode: C/s mode, allowing clients to download the boot image from a remote host server over the network and load the installation files or the entire system

There are three prerequisites to build PEX network system:

• The client's network card supports the PEX protocol, and the motherboard supports network boot

• A DHCP server is required on the network to automatically assign addresses to the client and specify the boot file location

• The server provides the download of the boot image file via tftp (Trivial file Transfer Protocol, simple Files Transfer Protocol)

I. Deploying a PXE installed server

1. Install the appropriate package and install it using the RPM package that comes with the CentOS system tray

2. Create the CentOS 6.5 installation source directory under the/var/ftp/directory, and copy the files from the system disk to that directory

3. Start the FTP service and note the configuration of the firewall

4. Configure the installation answer file

Open the Kickstart Configurator window from the desktop menu "Applications"-"System Tools"-"Kickstart"

It is then set according to the actual requirements, for example:

5. Start and configure the TFTP service

First, you need to modify the configuration file under TFTP

Then start the service and note the firewall with the port number "port 69th of UDP protocol"

Finally, copy the Linux kernel and initialize the image files to the root directory of TFTP.

4. Prepare the PXE bootstrapper and boot menu files

PXE Network installation Boot program is "pxelinux.0", provided by the package "Syslinux", a system is installed by default, if not installed, you can use the RPM package on the CD to install, and then copy "pxelinux.0" to the TFTP root directory

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M02/7C/DE/wKiom1bZkvbyxR74AAAxdKi-Ac4083.jpg "title=" Syslinux.jpg "alt=" Wkiom1bzkvbyxr74aaaxdki-ac4083.jpg "/>

The default boot menu file is "default" and should be placed in the PXELINUX.CFG subdirectory of the TFTP root directory (manually created)

6. Configure and start the DHCP service

Start the DHCP service, notice that the firewall

This allows the PXE installation server to be deployed

Second, the server is not installed system physical network connection, and then power on to complete the automatic installation
