搭建一键装机平台

一 、搭建DHCP服务

1.安装dhcp

2.修改配置文件

subnet 192.168.4.0  netmask  255.255.255.0 {

range 192.168.4.180  192.168.4.230;

next-server  192.168.4.168;

filename  "pxelinux.0";

}

3.重起dhcpd服务，设置开机自起动

二、搭建tftp

1.安装tftp-server

2.启动tftp服务，设置开机自起动

3. 部署pxeliunx.0

# yum provides */pxelinux.0

# rpm -ql syslinux | grep pxelinux.0

# cp /usr/share/syslinux/pxelinux.0  /var/lib/tftpboot/

# ls /var/lib/tftpboot/

4. 部署光盘内容

[[email protected] ~]# yum -y install httpd

[[email protected] ~]# mkdir /var/www/html/rhel6

[[email protected] ~]# mkdir /var/www/html/rhel7

[[email protected] ~]# mount /dev/cdrom  /mnt/      #光盘为rhel7.2

[[email protected] ~]# ls /mnt/

[[email protected] ~]# cp -r  /mnt/*    /var/www/html/rhel7/

[[email protected] ~]# umount  /mnt

[[email protected] ~]# mount /dev/cdrom  /mnt/   #光盘为rhel6.7

[[email protected] ~]# ls /mnt/

[[email protected] ~]# cp -r  /mnt/*    /var/www/html/rhel6/

[[email protected] ~]# du  -sh /var/www/html/rhel7/

[[email protected] ~]# du  -sh /var/www/html/rhel6/

5.部署rhel7、rhel6   的启动内核与驱动程序

# mkdir /var/lib/tftpboot/rhel6

# mkdir /var/lib/tftpboot/rhel7

# cp /var/www/html/rhel6/isolinux/vmlinuz

/var/www/html/rhel6/isolinux/initrd.img

/var/lib/tftpboot/rhel6/

# cp /var/www/html/rhel7/isolinux/vmlinuz

/var/www/html/rhel7/isolinux/initrd.img

/var/lib/tftpboot/rhel7/

# ls /var/lib/tftpboot/rhel7

# ls /var/lib/tftpboot/rhel6

6.部署图形模块与背景

# cp /var/www/html/rhel6/isolinux/vesamenu.c32

/var/lib/tftpboot/

# rpm -ql syslinux | grep jpg

# cp /usr/share/doc/syslinux-4.05/sample/syslinux_splash.jpg   /var/lib/tftpboot/

# ls /var/lib/tftpboot/

7.部署菜单文件

# mkdir /var/lib/tftpboot/pxelinux.cfg

# cp /var/www/html/rhel6/isolinux/isolinux.cfg

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

# chmod 644 /var/lib/tftpboot/pxelinux.cfg/default

# ls -l /var/lib/tftpboot/pxelinux.cfg/default

8.修改菜单文件内容

# vim /var/lib/tftpboot/pxelinux.cfg/default

......

menu background syslinux_splash.jpg

menu title Welcome to PXE Server!

......

label linux

menu label Install RHEL7.2

kernel rhel7/vmlinuz

append initrd=rhel7/initrd.img

label vesa

menu label Install RHEL6.7

kernel rhel6/vmlinuz

append initrd=rhel6/initrd.img

label local

menu label Boot from local drive

menu default                       #读秒结束最后默认选择

localboot 0xffff

三、搭建httpd服务共享光盘所有内容

1.启动服务

[[email protected] /]# systemctl restart httpd

[[email protected] /]# systemctl enable httpd

2.测试访问

[[email protected] /]# firefox  http://192.168.4.168/rhel6

[[email protected] /]# firefox  http://192.168.4.168/rhel7

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

四、生成ks文件

[[email protected] /]# yum -y install system-config-kickstart

修改Yum客户端配置文件的标示名

[development]

[[email protected] /]# system-config-kickstart  #先看“软件包选择”

软件包选择：  在“桌面”一栏选择----->第一个为GNOME  则为rhel7

RHEL7的文件系统为xfs

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

[[email protected] ~]# vim /etc/yum.repos.d/rhel7.repo

执行向rhel6的光盘

[development]

name=rhel7

baseurl=http://192.168.4.168/rhel6

enabled=1

gpgcheck=0

[[email protected] ~]# yum clean all       #清空Yum缓存

[[email protected] ~]# system-config-kickstart

软件包选择：  在“桌面”一栏选择----->第一个为KDE桌面  则为rhel6

RHEL6的文件系统为ext4

[[email protected] ~]# ls /root/ks*

/root/ks6.cfg  /root/ks7.cfg

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

五、指定ks应答文件

1.共享ks应答文件

[[email protected] ~]# cp /root/ks*  /var/www/html/

[[email protected] ~]# ls /var/www/html/

2.修改菜单文件

# vim /var/lib/tftpboot/pxelinux.cfg/default

label linux

menu label Install RHEL7.2

kernel rhel7/vmlinuz

append initrd=rhel7/initrd.img ks=http://192.168.4.

168/ks7.cfg

label vesa

menu label Install RHEL6.7

kernel rhel6/vmlinuz

append initrd=rhel6/initrd.img ks=http://192.168.4.

168/ks6.cfg
