PXE网络安装
===================================
安装环境:
[root@localhost ~]# lsb_release -a
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 5.5 (Tikanga)
Release: 5.5
Codename: Tikanga

-------------------------------
步骤一:安装DHCP服务器（前提：已经安装好网络YUM源）
[root@localhost ~]# yum -y install dhcp*
[root@localhost ~]# cat /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample > /etc/dhcpd.conf 
[root@localhost ~]# vi /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
        option routers                  192.168.1.1;
        option subnet-mask              255.255.255.0;
        option time-offset              -18000; # Eastern Standard Time
        range dynamic-bootp 192.168.1.128 192.168.1.254;
        default-lease-time 21600;
        max-lease-time 43200;
        filename        "pxelinux.0";
        next-server     192.168.1.1;
}
注意：
DHCP服务的PXE设置
next-server：指定TFTP服务器地址
filename：指定要下载的引导程序文件
[root@localhost ~]# service dhcpd start
启动 dhcpd：                                               [确定]
[root@localhost ~]# chkconfig dhcpd on
==================================================================================
步骤二：安装tftp-server并配置
[root@localhost ~]# yum -y install tftp-server //安装tftp-server，一般都已经安装好了
[root@localhost ~]# rpm -ql syslinux |grep pxelinux.0
/usr/lib/syslinux/pxelinux.0
[root@localhost ~]# cp /usr/lib/syslinux/pxelinux.0 /tftpboot/
[root@localhost ~]# mkdir /tftpboot/pxelinux.cfg
[root@localhost ~]# cp -rpf /media/isolinux/* /tftpboot/
[root@localhost ~]# cp /tftpboot/isolinux.cfg /tftpboot/pxelinux.cfg/default
[root@localhost ~]# chmod u+w /tftpboot/pxelinux.cfg/default
[root@localhost ~]# vi /tftpboot/pxelinux.cfg/default
default linux
prompt 1
timeout 60
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg

  kernel vmlinuz
  append initrd=initrd.img linux ks=ftp://192.168.1.1/ks.cfg
---------------------------------------------------------------
[root@localhost ~]# chkconfig tftp on
[root@localhost ~]# service xinetd restart
停止 xinetd：                                              [确定]
启动 xinetd：                                              [确定]
===================================================
步骤三(安装vsftpd 并配置ks.cfg文件):
[root@localhost ~]# rpm -q vsftpd
vsftpd-2.0.5-16.el5_4.1
[root@localhost ~]# cp anaconda-ks.cfg /var/ftp/ks.cfg
[root@localhost ~]# chmod 755 /var/ftp/ks.cfg 
[root@localhost ~]# vi /var/ftp/ks.cfg
# Kickstart file automatically generated by anaconda.
