PXE + Kickstart搭建局域网环境

PXE + Kickstart搭建局域网实验环境

配置环境：

a、本机ip：192.168.0.210，mac地址：20:6A:8A:68:E3:6E，主机名：server.example.com

b、rhel6.2的镜像挂在到了/var/ftp/pub/rhel6/下

c、ks.cfg放在了/var/www/html/

配置规划：

a、安装base包

b、配置好yum源

c、安装lftp软件

1、安装apache,用于发布kickstart配置文件ks.cfg

[root@server ~]# yum install httpd -y

[root@server ~]# chkconfig httpd on

[root@server ~]# service httpd start

2、安装tftp，用于支持pxe安装时连接发布机下载源

[root@server ~]# yum install tftp-server -y

[root@server ~]# vim /etc/xinetd.d/tftp

将disable的值由yes变为no，开启tftp服务

[root@server ~]# service xinetd restart

3、配置支持pxe的启动程序

[root@server ~]# cd /var/lib/tftpboot/

[root@server tftpboot]# yum install syslinux -y

[root@server tftpboot]# rpm -ql `rpm -qa|grep syslinux` | grep pxelinux

[root@server tftpboot]# cp /usr/share/syslinux/pxelinux.0 .

[root@server tftpboot]# mount -o loop /root/rhel-server-6.2-x86_64-dvd.iso /mnt/

[root@server tftpboot]# cp /mnt/images/{vmlinuz.initrd.img} /var/lib/tftpboot/

[root@server tftpboot]# cp /mnt/isolinux/boot.msg .

[root@server tftpboot]# mkdir pxelinux.cfg

[root@server tftpboot]# cd pxelinux.cfg/

[root@server pxelinux.cfg]# cp /mnt/isolinux/isolinux.cfg default

4、安装DHCP

[root@server ~]# yum install dhcp -y

[root@server ~]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

next-server 192.168.0.210;

filename "pxelinux.0"; //如果此行写在subnet下安装会失败！

subnet 192.168.0.0 netmask 255.255.255.0 {

range 192.168.0.100 192.168.0.150;

option domain-name-servers 192.168.0.210;

option domain-name "kevin.com";

option routers 192.168.0.210;

option broadcast-address 192.168.0.254;

default-lease-time 600;

max-lease-time 7200;

}

host server {

hardware ethernet 20:6a:8a:68:e3:6e;

fixed-address 192.168.0.210;

}

[root@server ~]# service dhcpd start

Starting dhcpd: [ OK ]

5、安装kickstart，安装系统的相关配置

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

[root@server ~]# system-config-kickstart &

保存到/var/www/html/ks.cfg

需要注意的写出来：

【Basic Configuration：加密码；开机重启；有必要使用图形安装】

【Installation Method：选择全新安装还是升级安装；安装源我这里选择ftp（server：192.168.0.210;directory:pub/rhel6）】

【Partition Information：移除所有磁盘空间还是移除linux分区；初始化磁盘标签还是保留原有的】

【Network Configuration：这里选择DHCP】

【Package Selection：这里只选择了BASE包】

【Post-Installation Script：安装完成后的脚本】

//这里配置了一个yum源

mkdir /var/cache/yum/x86_64/6Server/ -p

cat >>/etc/yum.repos.d/dvd.repo <<mine
