kickstart無人職守安裝

1 先將需要安裝的系統文件掛載到/mnt：

# mount -t cifs -o username=administrator,passwd=abcde //192.168.1.99/iso /mnt/

2 1-1 進入掛載的/mnt目錄，RPM安裝dhcp，tftp，kickstart：

#rpm -ivh *kickstart*

#rpm -ivh xinetd-2.3.14-10.el5.i386.rpm(tftp服務)

#rpm -ivh dhcp-3.0.5-23.el5.i386.rpm

rpm dhcp-devel-3.0.5-23.el5.i386.rpm

1-2 配置dhcpd：

# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf

# vi /etc/dhcpd.conf

        ddns-update-style interim;
        ignore client-updates;
        filename "pxelinux.0";
        next-server 192.168.1.22; （這裏寫入，不然的話系統會識別不到linux內核）
        subnet 192.168.1.0 netmask 255.255.255.0 {
                option routers                  192.168.1.22;
                option subnet-mask              255.255.255.0;
                option nis-domain               "domain.org";
                option domain-name              "domain.org";
                option domain-name-servers      192.168.1.1;
                option time-offset              -18000; # Eastern Standard Time
                range dynamic-bootp 192.168.1.128 192.168.1.229;
                default-lease-time 21600;
                max-lease-time 43200;
                # we want the nameserver to appear at a fixed address
                host ns {
                        next-server 192.168.1.22;
                        hardware ethernet 12:34:56:78:AB:CD;
                        fixed-address 192.168.1.22;
                }
        }
     #/etc/init.d/dhcpd

1-3 配置tftp：

# vi /etc/xinetd.d/tftp
將disable設置爲no

#/etc/init.d/xinetd start

# netstat -a | grep tftp

udp 0 0 *:tftp *:* off (0.00/0/0

#cd /mnt/centos5/isolinux;cp * /tftpboot/;mkdir pxelinux.cfg

然後將isolinux.cfg cp到新建的目錄pxelinux.cfg，更名爲：default

#vi /tftpboot/pxelinux.cfg/default

                    default linux
                    prompt 0
                    timeout 1
                    display boot.msg
                    F1 boot.msg
                    F2 options.msg
                    F3 general.msg
                    F4 param.msg
                    F5 rescue.msg
                    label linux
                      kernel vmlinuz
                      append ks=http://192.168.1.22/ks/ks.cfg initrd=initrd.img
                    label text
                      kernel vmlinuz
                      append initrd=initrd.img text
                    label ks
                      kernel vmlinuz
                      append ks initrd=initrd.img
                    label local
                      localboot 1
                    label memtest86
                    "default" 24L, 397C
