1、安裝並配置：DHCP服務：
1)yum list |grep dhcp
2)yum install dhcp* -y
3)編輯/etc/dhcpd.conf
√rpm -ql dhcp
√找到dhcpd.conf.example這個文件，復制到/etc下，替換dhcpd.conf
Cp ／usr/share/doc/dhcpd.conf.example /etc/dhcpd.conf
√vim /etc/dhcpd.conf
修改成如下：(注意紅色部分）
***********************************************************************
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
# option nis-domain "domain.org";
# option domain-name "domain.org";
# option domain-name-servers 192.168.1.1;
option time-offset -18000; # Eastern Standard Time
filename "pxelinux.0";
next-server 192.168.1.88;
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;
range dynamic-bootp 192.168.1.100 192.168.1.120;
default-lease-time 21600;
max-lease-time 43200;
# we want the nameserver to appear at a fixed address
host ns {
next-server marvin.redhat.com;
hardware ethernet 00:16:D3:07:68:27;
fixed-address 192.168.1.88;
}
}
***************************************************************************
√chkconfig dhcpd on
√service dhcpd restart
√如果報錯，則查看log日志，cat /var/log/message
2、安裝tftp:
1）安裝完成後會在根目錄產生一個tftpboot文件夾
Chkconfig tftp on
Service xinetd restart
2）復制必要的文件：
Cd /tftpboot
Cp /usr/lib/syslinux/pxelinux.0 /tftpboot
Cp /光盤／image／pxeboot/initrd.img
Cp /光盤／image／pxeboot/vmlinuz
Mkdir /tftpboot/pxelinux.cfg
Cp /光盤/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default
3）編輯default文件：
*************************************************************************
default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
kernel vmlinuz
append initrd=initrd.img linux ks=ftp://192.168.1.88/ks.cfg
label text
kernel vmlinuz
append initrd=initrd.img text
label ks
kernel vmlinuz
append ks initrd=initrd.img
label local
localboot 1
label memtest86
kernel memtest
append -
ftp://192.168.1.88/tftpboot/
*************************************************************
3配置ks.cfg文件：
完成後拷貝到/var/ftp/目錄中，和上面紅字對應。(不要忘記安裝VSFTP服務並配置）
備注：
啟動時如果在第一個界面DCHP 後面的那個-都跳不過去，也就是檢測不到 DHCP服務器就說明DHCP的設置有問題！！
