pxe+tftp+kickstart+dhcp+apache无人值守安装centos

一、安装环境
centos6.5 IP：192.168.100.11/24 GW:192.168.100.1
关闭iptables、selinux
二、需要安装组件
dhcp服务器
tftp服务器
kickstart生成的ks.cfg配置文件
提供安装镜像的httpd服务器
三、安装
1安装dhcp服务器

#yum install -y dhcp
#cp -a /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
#vim dhcpd.conf
ddns-update-style none;
option domain-name-servers 8.8.8.8;
log-facility local7;
allow booting;
allow bootp;
subnet 192.168.100.0 netmask 255.255.255.0 {
range  192.168.100.200 192.168.100.250;
option routers                  192.168.100.1;
option subnet-mask              255.255.255.0;
option broadcast-address        192.168.100.255;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.100.11; #TFTP Serverip
filename "pxelinux.0";   #pxelinux
}
~     #service dhcpd start
#chkconfig dhcpd on

2安装tftp服务器

#yum install -y tftp-server
#vim /etc/xinetd.d/tftp       #改如下两行
server_args             = -s /tftpboot
disable                 = no
#mkdir -p /tftpboot/pxelinux.cfg

3配置PXE

#yum install -y syslinux
#cp /usr/share/syslinux/pxelinux.0 /tftpboot
#mount -o loop CentOS-6.5-x84_64-minimal.iso /mnt
#cp  /mnt/images/pxeboot/vmlinuz /tftpboot/vmlinuz-centos6.5
#cp  /mnt/images/pxeboot/initrd.img  /tftpboot/initrd-centos6.5.img
#cp  /mnt/isolinux/isolinux.cfg  /tftpboot/pxelinux.cfg/default
#vim /tftpboot/pxelinux.cfg/default
default linux
prompt 1 # 显示 'boot: ' 提示符。为 '0' 时则不提示，将会直接启动 'default' 参数中指定的内容 label 可以定义多个系统，安装时'boot：'输入即可，例如linux。
timeout 600 #等待输入时间 单位0.1秒
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
kernel vmlinuz-centos6.5
append ks=http://192.168.100.11/config/ks.cfg/6.5x64.cfg initrd=initrd-centos6.5.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
kernel memtest
append -
#service xinetd restart

4安装配置httpd

#yum install -y httpd
#cd /var/www/html
#mkdir -p ISO/CentOS6.5
#mkdir -p config/ks.cfg
#cp -a /mnt/* /var/www/html/IOS/CentOS6.5
#service httpd start
#chkconfig httpd on

5准备ks.cfg文件

#cp /root/anaconda-ks.cfg  /var/www/html/config/ks.cfg/6.5x64.cfg
#/var/www/html/config/ks.cfg/6.5x64.cfg
#version=DEVEL
install
