PXE自动安装

server端的安装：
1.zypper in tftp vsftpd nfs-kernel-server
2。配置dhcp部分：
vi /etc/dhcpd.conf

# this can explicitely be specified
#deny unknown-clients;
#allow booting;
#allow bootp;
option broadcast-address 192.168.1.255;
option domain-name "linux";
option domain-name-servers 210.21.196.6;
option routers 192.168.1.237;
# a minimal /etc/dhcpd.conf example
# at first, edit /etc/sysconfig/dhcpd to configure all network interfaces
# that the server should listen on (DHCPD_INTERFACE)
# if you don't use dynamical DNS updates:
#
# this statement is needed by dhcpd-3 needs at least this statement.
# you have to delete it for dhcpd-2, because it does not know it.
#
# if you want to use dynamical DNS updates, you should first read 
# read /usr/share/doc/packages/dhcp-server/DDNS-howto.txt
ddns-update-style none;
ddns-updates off;
# this subnet is served by us
authoritative ;
max-lease-time 72000; # 1 week
default-lease-time 6000;
# these addresses will be given out dynamically
server-name "192.168.1.237";
#next-server 192.168.1.237;

filename "pxelinux.0";


subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.123 192.168.1.188;
  default-lease-time 14400;
  max-lease-time 172800;
}

host pxe-1{
hardware ethernet 44:37:E6:9B:6D:E3;
fixed-address 192.168.1.100;
}

修改配置文件/etc/sysconfig/dhcpd里面依赖的端口，设定一下。如：eth0
3.配置tftp部分
vi /etc/xinetd.d/tftp
# default: off
# description: tftp service is provided primarily for booting or when a \
#       router need an upgrade. Most sites run this only on machines acting as
#       "boot servers".
service tftp
{
        socket_type     = dgram
        protocol        = udp
        wait            = yes
        flags           = IPv4
        user            = root
        server          = /usr/sbin/in.tftpd
        server_args     = -s /tftpboot
        disable         = no
}
4.配置PXE下面的目录
ls /tftpboot/

5.配置nfs部分
编辑/etc/exports
vi /etc/exports
/source/suse101         *(fsid=0,ro,sync,root_squash)
/source/suse903         *(fsid=0,ro,sync,root_squash)

启动服务：
rcnfsserver start
rcxinetd start
rcdhcpd start
rcnfsserver start
rcvsftpd start
