## 一、准备软件仓库
##
#### 1.从光盘中复制软件包
##
mkdir -p /var/ftp/rhel5
# cp -rf /misc/cd/* /var/ftp/rhel5/
# 或者
service autofs restart
ls /misc/cd &> /dev/null
mount --bind /misc/cd /var/ftp/rhel5
##
#### 2.启动FTP服务
##
service vsftpd restart
chkconfig vsftpd on
##
#### 3.确认软件仓库可用（在本机或客户机中测试）
##
echo "[Server]
name=RHEL 5.4 Server
baseurl=ftp://$PXE_SVR/rhel5/Server
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[VT]
name=RHEL 5.4 VT
baseurl=ftp://$PXE_SVR/rhel5/VT
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[Cluster]
name=RHEL 5.4 Cluster
baseurl=ftp://$PXE_SVR/rhel5/Cluster
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[ClusterStorage]
name=RHEL 5.4 ClusterStorage
baseurl=ftp://$PXE_SVR/rhel5/ClusterStorage
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release" > /etc/yum.repos.d/rhel5.repo
##
##
## 二、配置TFTP服务，准备引导文件
##
#### 1.安装及配置tftp-server
##
yum -y install tftp-server
echo 'service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot/linux-install
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}' > /etc/xinetd.d/tftp
service xinetd restart
chkconfig xinetd on
##
#### 2.安装syslinux，准备引导文件
##
yum -y install syslinux
cd /var/ftp/rhel5/images/pxeboot/
/bin/cp -f vmlinuz initrd.img /tftpboot/linux-install/
##
##
## 三、配置DHCP服务
##
#### 1.安装dhcp软件包
##
yum -y install dhcp
##
#### 2.配置并启动dhcpd服务
##
#/bin/cp -f /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
echo 'ddns-update-style none;
ignore client-updates;
subnet '$NETWORK'.0 netmask 255.255.255.0 {
        option routers                  '$NETWORK'.1;
        option subnet-mask              255.255.255.0;
        option domain-name              "benet.com";
        option domain-name-servers      '$NETWORK'.1,202.106.0.20;
        option time-offset              -18000; # Eastern Standard Time
        range '$NETWORK'.50 '$NETWORK'.100;
        default-lease-time 21600;
        max-lease-time 43200;
        next-server '$PXE_SVR';       #//指定TFTP服务器地址
        filename "pxelinux.0";             #//指定所使用的引导程序名称
}' > /etc/dhcpd.conf
service dhcpd restart
chkconfig dhcpd on
##
##
## 四、准备PXE安装菜单
##
echo 'default auto
prompt 1
label auto
    kernel vmlinuz
    append initrd=initrd.img devfs=nomount ramdisk_size=8192
label linux text
    kernel vmlinuz
    append text initrd=initrd.img devfs=nomount ramdisk_size=8192
label linux rescue
    kernel vmlinuz
    append rescue initrd=initrd.img devfs=nomount ramdisk_size=8192' > /tftpboot/linux-install/pxelinux.cfg/default
##
## 五、为客户机安装系统（PXE方式）
#1.修改BIOS设置，优先从网卡（LAN或Network）启动
#2.重新启动客户机
#3.PXE安装过程
#    1）自动配置IP地址 -->
#    2）下载并运行引导程序pxelinux.0 -->
#    3）下载并运行vmlinuz、initrd.img -->
#    4）获取并显示安装菜单
#    5）选择安装方式，并进入系统安装向导
#    6）…… 完成系统安装
