kickstart网络自动安装

1.    安装配置tftp

# vim /etc/xinetd.d/tftp

service tftp

{

        socket_type             = dgram

        protocol                = udp

        wait                    = yes

        user                    = root

        server                  = /usr/sbin/in.tftpd

        server_args             = -s /tftpboot

        disable                 = no

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

 

2.    安装配置dhcp

# vim /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 10.10.11.0 netmask 255.255.255.0 {

        option routers                  10.10.11.1;

        option subnet-mask              255.255.255.0;

        option time-offset              -18000; # Eastern Standard Time

        range dynamic-bootp 10.10.11.100 10.10.11.200;

        default-lease-time 21600;

        max-lease-time 43200;

        next-server 10.10.11.153;

        filename "pxelinux.0";

}

 

3.    copy相关文件

# cp /usr/lib/syslinux/pxelinux.0 /tftpboot/

# cp -r /media/cdrom/isolinux/* /tftpboot/

# mkdir /tftpboot/pxelinux.cfg/

# mv /tftpboot/isolinux.cfg  /tftpboot/pxelinux.cfg/default

 

4.    配置/tftpboot/pxelinux.cfg/default为kickstart安装

# vim /tftpboot/pxelinux.cfg/default

label linux

  kernel vmlinuz

  append  ks=nfs:10.10.11.153:/kickstart/anaconda-ks.cfg initrd=initrd.img

 

5.    配置anaconda-ks.cfg

# vim /kickstart/anaconda-ks.cfg

install

nfs  --server 10.10.11.153 --dir /media/cdrom

lang zh_CN.UTF-8

 

6.    共享/media/cdrom 和/kickstart/目录

# vim /etc/exports

/media/cdrom      *(ro,sync)

/kickstart        *(ro,sync)

 

7. 重启服务
