一、部署dhcp服务器
1、安装软件包
yum -y install dhcp
2、配置文件
echo >/etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
-----------------------------
option domain-name "example.org";
#option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
next-server 192.168.1.118;
filename "pxelinux.0";
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.100;
option routers 192.168.1.254;
default-lease-time 600;
max-lease-time 7200;
}
3、启动服务、配置开机自启动
sed -i 's#user=dhcpd#user=root#g' /etc/init.d/dhcpd
sed -i 's#group=dhcpd#group=root#g' /etc/init.d/dhcpd
/etc/init.d/dhcpd start && chkconfig dhcpd on
二、部署tftp服务器
1、安装软件包
yum -y install tftp-server syslinux
2、修改配置文件
sed -i 's#yes#no#g' /etc/xinetd.d/tftp
/etc/init.d/xinetd restart
3、拷贝xftp 引导系统需要的配置文件
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
mkdir /var/lib/tftpboot/pxelinux.cfg/
#挂载光盘到mnt目录#
mount -o loop -t iso9660 /dev/cdrom /mnt
cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
sed -i 's#img$#img ks=http://192.168.1.118/ks.cfg ksdevice=eth0#' /var/lib/tftpboot/pxelinux.cfg/default
sed -i 's#600#60#g' /var/lib/tftpboot/pxelinux.cfg/default
sed -i '/menu default/d' /var/lib/tftpboot/pxelinux.cfg/default
sed -i '/label local/a \ menu default' /var/lib/tftpboot/pxelinux.cfg/default
cp /mnt/isolinux/vesamenu.c32 /var/lib/tftpboot/
cp /mnt/isolinux/boot.msg /var/lib/tftpboot/
cp /mnt/isolinux/initrd.img /var/lib/tftpboot/
cp /mnt/isolinux/vmlinuz /var/lib/tftpboot/
cp /mnt/isolinux/splash.jpg /var/lib/tftpboot/
chmod -R +x /var/lib/tftpboot
三、部署httpd服务
1、安装软件包
yum -y install httpd && chkconfig httpd on && /etc/init.d/httpd start
2、配置文件
mkdir -p /var/www/html/repo
#重新挂载光驱到/var/www/html/repo
cd / && umount /mnt && mount -o loop -t iso9660 /dev/cdrom /var/www/html/repo
vim /var/www/html/ks.cfg
