6-3pxe应用入门

172.18.253.208
yum　install dhcp tftp-server tftp syslinux vsftpd---配置成一个dhcp server
此时还需要一个kickstart文件，视频中是从服务器获取
Centos 6改IP地址使用setup命令192.168.10.16 255.255.255.0 网关192.168.10.1
service network restart
ifconfig---查看ip地址有没有配置上去
ssh root@192.168.10.16
vim /etc/ssh/sshd_config
UseDNS no---这里改为no
service sshd reload

先配置dhcp服务
cd /etc/dhcp
cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample ./dhcpd.conf
vim dhcpd.conf
option domain-name "mageedu.com";
option domain-name-servers 172.18.0.1;

default-lease-time 600;
max-lease-time 7200;

log-facility local7;

subnet 192.168.10.0 netmask 255.255.255.224 {
range 192.168.10.151 192.168.10.160;
filename "pxelinux.0";
next-server 192.168.10.16;
}

service dhcpd configtest
service dhcpd start
ss -unl---67端口
chkconfig dhcpd on---开机自动启动

接下来准备tftp服务
chkconfig tftp on，也可以编辑配置文件
vim /etc/xinetd.d/tftp
service tftp
{
Socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = yes---这里改为no
per_source = 11
cps = 100 2
flags = IPv4
}
service xinetd restart
chkconfig xinetd on
ss -unl---69号端口
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cd /tmp
tftp 192.168.10.16---这里是测试tftp服务是否正常
get pxelinux.0

接下来就该复制光盘中的文件了，虚拟机挂载的是物理机中的光盘
mkdir /media/cdrom
mount -r /dev/cdrom /media/cdrom
ls /media/cdrom
cp /media/cdrom/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/
cp /media/cdrom/isolinux/{boot.msg,vesamenu.c32,splash.jpg} /var/lib/tftpboot
mkdir /var/lib/tftpboot/pxelinux.cfg/
cp /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
chmod +w /var/lib/tftpboot/pxelinux.cfg/default
vim /var/lib/tftpboot/pxelinux.cfg/default
default vesamenu.c32

timeout 600

display boot.msg

接下来需要准备yum仓库
mkdir /var/ftp/pub/centos
mount --bind /media/cdrom/ /var/ftp/pub/cnetos---这是绑定的方式
vim centos6.cfg---kickstart文件
firewall --disabled
