- Server

DHCP: Assigning addresses, locating boot files

TFTP: provides bootloader download

FTP: Provide installation source (Yum repository)

Kickstart: Create an answer file for unattended, fully automated installation, and add scripts to implement post-installation configuration.

- Client

The NIC needs to support the PXE protocol

Motherboard needs to support network boot

II. deployment Process 1. Prepare the installation source

[Email protected] ~]# mkdir-p/var/ftp/centos6.5[[email protected] ~]# cp-rf/media/centos_6.5_final/*/var/ftp/ Centos6.5/[[email protected] ~]# Rpm-ivh/var/ftp/centos6.5/packages/vsftpd-2.2.2-11.el6_4.1.x86_64.rpm[[email Protected] ~]# service vsftpd start for vsftpd boot vsftpd: [OK][[email protected] ~]# Chkcon Fig VSFTPD on

2. Enable the TFTP service and provide the kernel, boot program

- Installing TFTP

[[email protected] ~]# yum-y installtftp-server-Modify configuration file, enable Tftp[[email protected] ~]# vim/etc/xinetd.d/tftpdisable = No

- start tftp

[[Email protected] ~]# Service xinetd start is starting xinetd: [OK]

- Copy the boot file to the TFTP root directory

[[email protected] ~]# Cd/var/ftp/centos6.5/images/pxeboot/[[email protected] pxeboot]# CP vmlinuzinitrd.img/var/lib/ Tftpboot/[[email protected] pxeboot]# yum-y installsyslinux[[email protected] ~]# cp/usr/share/syslinux/pxelinux.0/ var/lib/tftpboot/

3. Enable DHCP service to assign addresses, indicate bootstrapper location

- Install DHCP

[[Email protected]~]# yum-y Install DHCP

- Modifying a configuration file

[Email protected] ~]# vim/etc/dhcp/dhcpd.confsubnet 192.168.10.0 netmask 255.255.255.0 {option Routers 192.168.10.       254;       Option Domain-name-servers 202.106.0.20;       Range 192.168.10.100192.168.10.200;         Next-server 192.168.10.254;           #指定TFTP服务器地址 filename "pxelinux.0"; #指定要下载的引导程序文件}

- Start DHCP

[[Email protected] ~]# Service DHCPD start is starting dhcpd: [OK]

4. Create an answer file

5. Configure the Boot Menu

- Deploy an answer file in a location that the client can access

[Email protected] ~]# cp/root/ks.cfg/var/ftp/centos6.5/ks.cfg

- To Create a boot menu file

[Email protected] ~]# mkdir/var/lib/tftpboot/pxelinux.cfg[[email protected] ~]# vim/var/lib/tftpboot/pxelinux.cfg/ Default

- Edit the boot menu file

Default autoprompt 0label Auto kernel vmlinuz append ks=ftp://192.168.10.254/centos6.5/ks.cfg initrd=initrd.im Gdevfs=nomount ramdisk_size=8192
