Howto pxe install centos

first we install the following packages:

yum install xinetd dhcp vsftpd syslinux syslinux-tftpboot bind-chroot system-config-kickstart tftp tftp-server -y

configure your network ip address as static:

nmcli con del eth0
nmcli con del Wired\ connection\ 1
nmcli con add con-name eth0 ipv4.method manual type ethernet ifname eth0 ipv4.addresses 192.168.1.24/24 ipv4.gateway 192.168.1.24 ipv4.dns 4.2.2.1,4.2.2.2 autoconnect yes

create dhcpd config file /etc/dhcp/dhcpd.conf:

Allow booting;
Allow bootp;
authoritative;

# Subnet definition
subnet 192.168.1.0 netmask 255.255.255.0 {
# Parameters for the local subnet
option routers               192.168.1.254;
option subnet-mask           255.255.255.0;
option domain-name           "example.com";
option domain-name-servers   192.168.1.254;
default-lease-time           21600;
max-lease-time               43200;
# Client IP range
range dynamic-bootp 192.168.1.100 192.168.1.200;
filename  "pxelinux.0";
next-server  192.168.1.24;
}

configure tftp service edit /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
