批量安装centos,不用kickstart

1. 定制livecd
   安装宿主系统(系统分区不能使用LVM)安装livcd-tools
      创建文件/etc/yum.repos.d/centos-livecd.repo

   内容如下：

   # Name: CentOS LiveCD repository
   [livecd]name = CentOS $releasever - LiveCD
   baseurl = http:///propos/linux/centos-live/$basearch/live
   enabled=1
   protect=0
   gpgkey = http:///propos/linux/RPM-GPG-KEY-PGuay2010
   
   安装
   yum install livecd-tools syslinux anaconda-runtime
   
   #创建配置文件mini.ks
   
   # Kickstart file automatically generated by anaconda.
   
   #cdrom
   repo --name=base --baseurl=
   #repo --name=a-base --baseurl=
   #repo --name=a-updates --baseurl=
   
   #repo --name=a-extras --baseurl=
   #repo --name=a-live --baseurl=http:///propos/linux/centos-live/$basearch/live
   
   
   lang en_US.UTF-8
   keyboard us
   network --device eth0 --bootproto dhcp --hostname minnicentos
   authconfig --enableshadow --enablemd5
   selinux --disabled
   firewall --disabled
   timezone --utc Asia/Shanghai
   # The following is the partition information you requested
   # Note that any partitions you deleted are not expressed
   # here so unless you clear all partitions first, this is
   # not guaranteed to work
   %packages
   bash
   kernel
   syslinux
   passwd
   policycoreutils
   chkconfig
   authconfig
   rootfiles
   comps-extras
   xkeyboard-config
   openssh-server
   net-tools
   vim-minimal
   netpbm
   #netpbm-progs
   nfs-utils-lib
   nfs-utils
   portmap
   rsync
   libdhcp4client
   libdhcp
   

运行命令创建mini-livecd 

livecd-creator --config=anaconda-ks.cfg  --fslabel=CentOS-minimalls

生成pxe boot启动用的系统

livecd-iso-to-pxeboot  把产生的initrd0.img，vmlinuz0两个文件放到分发服务器的/tftpboot下

     

2. 准备一台分发服务器上面安装 tftp-server , dhcp, NFS  

   配置修改 /etc/xinetd.d/tftp  

   disable  yes改成 NO

复制系统下/usr/lib/syslinux/pxelinux.0,menu.c3 到 /tftpboot

cat  << EOF >  /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;
default-lease-time 21600;
max-lease-time 43200;
authourtative;
next-server 192.168.56.101;
subnet 192.168.56.0 netmask 255.255.255.0 {
    option routers          192.168.56.1;
    option subnet-mask      255.255.255.0;
    range 192.168.56.50 192.168.56.100;
    default-lease-time 21600;
    max-lease-time 43200;
    filename "pxelinux.0";
    option domain-name-servers 127.0.0.1 ;
}

EOF

在/tftpboot/下 创建如下两个文件

cat << EOF > defalut

default menu.c32
prompt 0
timeout 300
ONTIMEOUT local

MENU TITLE Boot from network

LABEL local
        MENU LABEL Boot local hard drive
        LOCALBOOT 0

        MENU LABEL Install Linux with MinLinx
        KERNEL menu.c32
        APPEND pxelinux.cfg/min

LABEL x86_64 Servers
        MENU LABEL Install Linux with Kickstart
        KERNEL menu.c32
        APPEND pxelinux.cfg/kick

LABEL Tools
        MENU LABEL Windows2003 server
        KERNEL menu.c32
        APPEND pxelinux.cfg/windows
EOF

########################################

cat << EOF > min

        MENU LABEL Min Install Menu
        KERNEL menu.c32
        APPEND pxelinux.cfg/default

        MENU LABEL CentOS 5 x86_64 NO KS eth0
        KERNEL vmlinuz0
        APPEND initrd=initrd0.img root=/CentOS-minimal.iso rootfstype=iso9660 rootflags=loop

        MENU LABEL CentOS 5 x86_64 NO KS eth1
        KERNEL images/centos/5/x86_64/vmlinuz
        APPEND ks initrd=images/centos/5/x86_64/initrd.img ramdisk_size=100000 ksdevice=eth1 ip=dhcp url --url

EOF

3.自动安装系统

• 服务器网络启动选择mini os,进入livecd
• 用fdisk 格式化 /dev/sda 两个区一个boot 区 一个 / 分区，根分区做成lvm
• 然后mount / 分区
• 用dd if=/dev/源分区 of=/dev/目的分区
• 用rsync 把 /目录下的内容 同步到分到区的 / 目录中。
