手动

需要安装dhcp。vsftp。ftp。xinetd。。。。。。

yum install dhcp 

vi /etc/dhcp/dhcpd.conf

ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.1.144 192.168.1.147; #段
option domain-name-servers 8.8.8.8,192.168.1.1; #dns服务
option subnet-mask 255.255.255.0; #掩码
option time-offset -18000; #租用时间
option routers 192.168.1.1; #吓一跳，网关
default-lease-time 21600; #默认时间
max-lease-time 43200; #最大租用时间
next-server 192.168.1.142;
filename "pxelinux.0";
}

yum install tftp tftp-server syslinux vsftp

yum intall xinetd cvs-inetd.noarch

vi /etc/xinetd.d/tftp 

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}

mkdir /tftpboot

cp /usr/share/syslinux/pxelinux.0 /tftpboot

chcon -R -t tftpdir_rw_t /tftpboot

cd /run/media/root/CentOS\ 7\ x86_64/images/pxeboot/

cp vmlinuz initrd.img /tftpboot/

mkdir /tftpboot/pxelinux.cfg

vi /tftpboot/pxelinux.cfg/default

default 0
prompt 1
timeout 300
display boot.msg

localboot 0
label 1

append initrd=initrd.img noipv6 ks=ftp://192.168.1.142/ks.cfg

#label 2
#kernel vmlinuz
#append initrd=initrd.img noipv6 ks=ftp://192.168.1.142/ks.cfg

chmod 644 /tftpboot/pxelinux.cfg/default

在/tftp下写boots.ms     可以用第三方源 toilet

vi /var/ftp/ks.cfg  #执行权限  也可以拷贝anaconda-ks.cfg
