pxe安装centos

时间：2007-01-08 来源：kelly_sh

1、客户机的配置
在bios中设置客户机以pxe方式启动 2、服务器的配置
1 安装tftp和dhcp服务器
# rpm -ivh tftp-server-0.39-0.EL3.1.c0.i386.rpm
# rpm -ivh dhcp-3.0.1-10_EL3.i386.rpm
2 配置tftp和dhcp服务器
配置dhcp服务器
# cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf
# vi /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 172.1.6.0 netmask 255.255.255.0
{
   option routers 172.1.6.1;
   option subnet-mask 255.255.255.0;
   option time-offset -18000;
   default-lease-time 21600;
   max-lease-time 43200;
   range dynamic-bootp 172.1.6.91 172.1.6.99;
   filename "pxelinux.0"; } 配置tftp服务器(port 69)
# vi /etc/xinetd.d/tftp
=============+==========+===========+============+============
service tftp
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -u nobody -s /tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
} 关闭防火墙：iptables stop
把LINUX第一张安装光盘上/image/pxeboot/initr.img和vmlinux 以及isolinux/*.msg考到/tftpboot目录下
# cd /tftpboot
# mkdir pxelinux.cfg
# vi default 并存入刚刚建立的pxelinux.cfg目录

append initrd=/centos44/images/pxeboot/initrd.img lowres ramdisk_size=8192 =============+==========+===========+============+============
3 启动dhcp service dhcpd start
启动tftp service xinetd restart
查看系统日志观察是否启动成功
4 在http或ftp或nfs服务器中建立安装源文件树
以http为例:

centos/
        |
        |__i386/
        |   |
        |   |__CentOS
        |   |   |
        |   |   |__RPMS/
        |   |   |__base/
        |   |
        |   |__RELEASE_NOTE_en.html
        |
        |__ks.cfg
5 vi ks.cfg 由/root/下anaconda-ks.cfg下修改而成。 lang en_US.UTF-8

6 待安装机器使用pxe启动,出现boot：菜单后输入linux ks=http://172.1.6.8/tftpboot/ks.cfg即可。
