pxe自动化安装系统

1、#挂载镜像到/mnt下

[root@localhost ~]# mount /dev/cdrom /mnt

[root@localhost ~]# vim /etc/yum.repos.d/yum.repo [aaa]name=anbaseurl=file:///mnt/Servergpgcheck=0

2、oot@localhost ~]# vim /etc/dhcpd.confddns-update-style interim;ignore client-updates;

subnet 192.168.0.0 netmask 255.255.255.0 {

        option routers                  192.168.0.106;        option subnet-mask              255.255.255.0;        next-server                     192.168.0.106;        filename                        "pxelinux.0";        option nis-domain               "domain.org";        option domain-name              "domain.org";        option domain-name-servers      192.168.0.106;

        option time-offset              -18000; # Eastern Standard Time

        range dynamic-bootp 192.168.0.128 192.168.0.254;        default-lease-time 21600;        max-lease-time 43200;

}   

3、  [root@localhost /]# ls backup  dev   lib         misc  opt   sbin     srv       tmpbin     etc   lost+found  mnt   proc  selinux  sys       usrboot    home  media       net   root  share    tftpboot  var

如果没有 yum -y install tftp-server
