How to make a PXE Server?

The title is really XXX. The PXE Service has a series small service to comprise. Such as tftp, dhcp , nfs and kickstart cfg file , etc.

# Install Syslinux

yum install -y syslinux
mkdir -p /tftpboot/
cp -rvf /usr/share/syslinux/* /tftpboot/

# Install tftp-server

yum install -y tftp-server
编辑/etc/xinetd.d/tftp 将disable改成no
service xinetd restart

# Install dhcp server
yum install -y dhcp

# Edit File /etc/dhcp/dhcpd.conf

subnet 172.172.172.0 netmask 255.255.255.0 {
subnet-specific parameters...
        range 172.172.172.2 172.172.172.254;
        option domain-name-servers 42.96.162.172;
option routers 172.172.172.1;
        max-lease-time 120;
        default-lease-time 120;
filename "pxelinux.0"
next-server 42.96.162.172;
}

Attention: DHCP配置的时候， subnet一定和 eth0 或者某个接口在同一个网段， 子接口好像有点问题。

# you should exact the iso file to the dir /net-install/centos/6.3/x86_64/
# if the iso is at /tmp/1.iso, the following are commands to do this job.
mkdir -p /net-install/centos/6.3/x86_64/
