1.2 configuration dhcp

#  vi /etc/dhcp/dhcpd.conf
# default-lease-time 600;
#  max-lease-time 7200;
ddns-update-style none;
log-facility local7;
next-server 192.168.1.1; //指定tftp服务器ip，该ip地址这里指定本机地址
filename "pxelinux.0"; //指定引导文件
subnet 192.168.1.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.1.10 192.168.1.100; //设置dhcp作用域范围
# option domain-name-servers 8.8.8.8;
# option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
default-lease-time 600;
max-lease-time 7200;

# 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 //设置tftp的根目录
disable = no //这里原来是yes要改成no
per_source = 11
cps = 100 2
flags = IPv4
}

cd /var/lib/tftp
mkdir pxelinux.cfg

System OFF to mount the disk / mnt / cdrom directory

# mount /dev/cdrom /mnt/cdrom
# cp /mnt/cdrom/images/*.img /var/lib/tftpboot
# cp /mnt/cdrom/isolinux/boot.msg /var/lib/tftpboot
# cp /mnt/cdrom/isolinux/initrd.img /var/lib/tftpboot
# cp /mnt/cdrom/isolinux/vesamenu.c32 /var/lib/tftpboot
# cp /mnt/cdrom/isolinux/vmlinuz /var/lib/tftpboot
# cp /mnt/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
# chmod -R 755 /var/lib/tftpboot //让tftp目录下的所有文件有执行权限
#chmod 777 /var/lib/tftpboot/pxelinux.cfg/default

Pxelinux.0 get the boot file

# yum install syslinux
# rpm -qa | grep syslinux
# rpm -ql syslinux-4.02-7.el6.x86_64 | grep pxelinux.0 //查找 pxelinux.0所在位置
# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

</Directory>

# service dhcpd start
# service xinetd start

4.2 selinux closed and iptables

# set enforce0
# service iptables stop

5. Install the operating system from a network can be installed, each different server network startup mode, described here no longer Ao, fill http://192.168.1.1/iso switched in the step of selecting the installation source: http: //www.zhengdazhi .com / index.php / centos6-3-pxe% E5% AE% 89% E8% A3% 85% E7% B3% BB% E7% BB% 9F / finishing: operation and maintenance of survival time
