# chkconfig --levels 35 dhcpd  on
# chkconfig --list |grep dhcpd
dhcpd           0:off   1:off   2:off   3:on    4:off   5:on    6:off
# service dhcpd restart

2.配置Apache
# yum -y install httpd

# service httpd restart
# chkconfig --levels 35 httpd on

3.配置tftp
# yum -y install tftp-server tftp

# cat /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        disable                 = no                      #"yes"改为"no"
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}
# cp -rf /var/www/html/ubuntu1204/install/netboot/*  /var/lib/tftpboot/
# service xinetd restart

4.修改配置
增加ks=http://192.168.2.25/ks.cfg
# cat  /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg
default install
label install
        menu label ^Install
        menu default
        kernel ubuntu-installer/amd64/linux
        append ks=http://192.168.2.25/ks.cfg vga=788 initrd=ubuntu-installer/amd64/initrd.gz -- quiet
label cli
        menu label ^Command-line install
        kernel ubuntu-installer/amd64/linux
        append tasks=standard pkgsel/language-pack-patterns= pkgsel/install-language-support=false vga=788 initrd=ubuntu-

installer/amd64/initrd.gz -- quiet

5.配置ks文件
通过system-config-kickstart界面生成ks.cfg文件
# apt-get install system-config-kickstart
# scp ks.cfg [email protected]:/var/www/html

附ks.cfg
