Centos 6.5无人值守安装

步骤

1、mount /dev/sr0 /media/

2、安装所需要的软件

安装并配置tftp服务

yum install tftp tftp-server vsftpd dhcp syslinux nfs-utils
vim /etc/xinetd.d/tftp
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
per_source = 11
cps = 100 2
flags = IPv4
}

配置dhcp

# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#

allow booting;
allow bootp;

# A slightly different configuration for an internal subnet.
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.60;
option domain-name-servers KangChangWei;
option domain-name "KangChangWei";
option routers 192.168.1.1;
default-lease-time 600;
max-lease-time 7200;
filename "pxelinux.0";
next-server 192.168.1.101;
}

以上IP可以根据自己所在的网络修改

3、复制所需要的启动文件

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
cp /mnt/images/pxeboot/initrd.img /var/lib/tftpboot
cp /media/images/pxeboot/initrd.img /var/lib/tftpboot/
cp /media/images/pxeboot/vmlinuz /var/lib/tftpboot/

mkdir /var/lib/tftpboot/pxelinux.cfg
cp /media/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

编辑

Vim /var/lib/tftpboot/pxelinux.cfg/default

default linux
#default vesamenu.c32
prompt 1
timeout 600

display boot.msg

menu background splash.jpg

append -

4、共享光盘

vim /etc/export
/media *(ro,sync)

启动nfs服务

[root@kcw ~]# /etc/init.d/rpcbind restart
停止 rpcbind: [确定]
正在启动 rpcbind: [确定]
[root@kcw ~]# /etc/init.d/nfs restart
关闭 NFS 守护进程: [确定]
关闭 NFS mountd: [确定]
关闭 NFS 服务: [确定]
Shutting down RPC idmapd: [确定]
启动 NFS 服务: [确定]
启动 NFS mountd: [确定]
启动 NFS 守护进程: [确定]
正在启动 RPC idmapd: [确定]

查看nfs输出

[root@kcw ~]# showmount -e localhost
Export list for localhost:
/media *

生成ks.cfg文件安装工具

[root@kcw ~]# yum install system-config-kickstart

然后运行

system-config-kickstart

来修改页面得到自己安装的客户端 我这里省略。。

这有个做好的ks.cfg

内容如下:

#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
key --skip
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use network installation
nfs --server=192.168.1.101 --dir=/media

注意我这块root密码是redhat

我这里分区时lvm分区根据你的需求也可以修改

然后把ks.cfg放到你的vsftpd默认可以访问的目录里

即:

[root@kcw ~]# cd /var/ftp/pub/
[root@kcw pub]# ls
ks.cfg
[root@kcw pub]# pwd
/var/ftp/pub

注意先测试你的这个文件能不能访问打开IE输入ftp://192.168.1.101/pub/ks.cfg

看能否看到内容!

做完重启dhcp vsftpd xine xinetd nfs

然后重新开台电脑开机设置从网卡引导看能否启动成功并且自动安装

我这块等待默认600秒 自动安装

开机引导到boot:时按回车安装
