1 安装并配置dhcpd服务yum install dhcp
[root@localhost pub]# vim /etc/dhcp/dhcpd.conf
subnet 172.16.1.0 netmask 255.255.255.0 {
range 172.16.1.2 172.16.1.253;
option routers 172.16.1.254;
option subnet-mask 255.255.255.0;
option broadcast-address 172.16.1.255;
default-lease-time 600;
next-server 172.16.1.1;
max-lease-time 7200;
filename "/pxelinux.0";
}
systemctl start dhcpd
systemctl enable dhcpd
2 安装并配置vsftpd服务
本次pxe安装源使用的是vsftp作为安装树
yum install vsftpd
systemctl start vsftpd
systemctl enable vsftpd
这里vsftpd使用的都是默认配置
3 之后把整个iso都拷贝到ftp的目录
[root@localhost pub]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 20G 0 disk
├─sda1 8:1 0 200M 0 part /boot
└─sda2 8:2 0 19.8G 0 part
├─server-root 253:0 0 18.8G 0 lvm /
└─server-swap 253:1 0 1G 0 lvm [SWAP]
sr0 11:0 1 3.8G 0 rom /run/media/root/RHEL-7.2 Server.x86_64
或者使用findmnt来找到光盘挂在在了哪里，或者使用df -h也可以看到
cp -axv /run/media/root/RHEL-7.2 Server.x86_64 /var/ftp/pub
4 安装并配置tftp服务
yum install tftp-server
[root@localhost ~]# 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 = no
per_source = 11
cps = 100 2
flags = IPv4
}
systemctl start tftp
systemctl enable tftp
5 将必要文件及配置放到/var/lib/tftpboot
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cp -axv /var/ftp/pub/isolinux/* /var/lib/tftpboot/
mkdir /var/lib/tftpboot/pxelinux.cfg
cp /var/ftp/pub/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
查看default文件的配置==将default文件设置为下边这样
[root@localhost pxelinux.cfg]# vim /var/lib/tftpboot/pxelinux.cfg/default

注意：
1 在pxe安装客户端系统之前，最好先使用光盘或usb来安装一套rhel7，之后使用该物理机作为pxe安装源，这样有2个好处：1 能得到一个针对这批服务器端ks文件；2 能得到这批服务器的网卡名，这样你在这个ks中就可以在network部分写上这个网卡名了。默认情况下rhel7针对不同的服务器，网卡叫不同的名字
7 客户端安装系统
在客户端加电，使用网络引导，客户端会自动安装OS
