第三次整理[/b]
一：准备工作[/b]
1：安装centos系统，配置好网络
二：安装各软件[/b]
1[/b]：配置yum[/b]
2[/b]：安装kickstart[/b]
# yum -y install system-config-kickstart.noarch
3[/b]：安装配置nfs[/b]
#yum -y install nfs-utils
# vim /etc/exports
/misc/cd 192.168.1.0/24(rw,no_root_squash)
/kickstart 192.168.1.0/24(rw,no_root_squash)
# exportfs -av
4[/b]：安装配置dhc[/b]p
# yum –y install dhcp
#cp /usr/share/doc/dhcp*/dhcpd.conf.sample /etc/dhcpd.conf
#vim /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;

subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option domain-name "domain.org";
option domain-name-servers 192.168.1.1;
option time-offset -18000; # Eastern Standard Time
range dynamic-bootp 192.168.1.150 192.168.1.199;
default-lease-time 21600;
max-lease-time 43200;
next-server 192.168.1.100; #TFTPServer的IP
filename "/pxelinux.0"; #pxelinux loader文件位置
}
#chkconfig dhcpd on
#etc/init.d/dhcpd start

5:[/b]安装[/b]TFTP
# yum -y install tftp-server.i386
启动tftp服务
# chkconfig xinetd on
#/etc/init.d/xinetd start
#chkconfig tftp on
# chkconfig --list|grep tftp
tftp: on
三：配置[/b]
1[/b]：生存kickstart[/b]配置文件[/b]
在x-downs[/b]下[/b]
