1、安装配置DHCP
用于给客户端提供IP
yum -y install dhcp
cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
编辑dhcpd.conf
allow booting; //支持PXE启动
allow bootp; // 支持bootp
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.10 192.168.1.50;
default-lease-time 6000;
max-lease-time 72000;
next-server 192.168.1.80;
filename "/pxelinux.0";
}
2、安装配置TFTP
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot //tftp服务器的根目录
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
service xinetd restart //重启服务器生效
3、拷贝启动所需的文件并配置
yum -y install syslinux /安装syslinux，此服务为pxe提供pxelinux.0文件即boostrap文件
cp /usr/share/syslinux/pxelinux.0 /tftpboot/ //pxelinux.0文件不一定就在这个目录下，通过find来查找
mkdir /mnt /install
mount /dev/cdrom /mnt/install
cp /mnt/install/pxeboot/{vmlinuz,initrd.img} /tftpboot/ //vmlinuz内核文件、initrd.img根文件系统
创建/tftpboot/pxelinux.cfg/ 目录，该目录用于存放客户端的配置文件
cp /Media/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default /这个文件可修改安装界面
查看文件是否拷贝齐全（可能多上传了，不过没影响）
注：拷贝的文件注意更改root权限，建议直接777，没影响
default vesamenu.c32
#prompt 1
timeout 600
display boot.msg

append ks=nfs:192.168.1.80:/mnt/ks.cfg initrd=initrd.img //指定ks文件目录

kernel vmlinuz
append initrd=initrd.img rescue
label local
menu label Boot from ^local drive

menu label ^Memory test
kernel memtest
append -
4、安装配置NFS服务器
yum -y rpcbind install //centos5中，这服务叫portmap
yum -y nfs install
/mnt/install *(ro,sync)//sync：文件同时写入硬盘和内存；
showmount -e localhost //查看是否发布成功
[root@cedar tftpboot]# showmount -e localhost
Export list for localhost:
/mnt/install 192.168.1.*
/mnt 192.168.1.*
5、安装配置kickstart生成ks.cfg文件
yum -y install system-config-kickstart
system-config-kickstart //调出界面制作ks.cfg文件
ks配置文件内容如下：
[root@cedar tftpboot]# cat /mnt/ks.cfg
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use NFS installation media
nfs --server=192.168.1.80 --dir=/mnt/install
# Root password
rootpw --iscrypted $1$VFLk79.d$rCSW91yvcDZSkAXgmTYI7.
# System authorization information

part swap --fstype="ext4" --size=1024
part /boot --fstype="ext4" --size=200
part /var --fstype="ext4" --size=1024

6、关闭防火墙和SElinux
避免未知的错误需要关闭防火墙和SElinux
service iptables restart
修改/etc/selinux/config
SELINUX=disabled
7、测试
新建一个虚拟机，网卡都选host-only的VM2
一路安装直至完成！！！
