无人安装值守pxe

pxe无人值守安装linux

简要介绍:我这里使用的是 dhcp+tftp+ftp+kickstat使用的组合工具

yum -y install xinetd dhcpd tftpdtftp-server syslinux system-config-kickstart

 

# 运行system-config-kickstart命令然后保存ks.cfg文件

 

vim /etc/dhcp/dhcpd.conf

subnet 192.168.8.0 netmask 255.255.255.0 {

       option routers 192.168.8.101;

       range 192.168.8.103 192.168.8.200;

       option domain-name-servers 192.168.8.101;

       filename "pxelinux.0";

       next-server 192.168.8.101;

       default-lease-time 600;

       max-lease-time 7200;

}

 

# 改完之后重新dhcpd

 

# 命令详解

# option routers              dhcp路由地址

# range                   dhcp分配地址池

# default-lease-time           dhcp默认时长

# filename                  pxe服务名称

# next-server                pxe服务器地址

# allow members               pxe最大值

 

 

vim /etc/xinetd.d/tftp

disable                 = no

# 将disable 改为no  改完之后重新瞬间守护进程

 

service xinetd restart

 

 

mount -t iso9660 /dev/sr0 /mnt

# 1. pxelinux.0, vesamenu.c32放到tftp根目录下        这个目录/var/lib/tftpboot/是默认的

cp/usr/share/syslinux/{pxelinux.0,vesamenu.c32} /var/lib/tftpboot/

 

# 2.创建pxelinux.cfg目录 ，该目录下准备存放default文件

mkdir /var/lib/tftpboot/pxelinux.cfg

 

# 3.创建要安装系统目录CentOS，拷贝initrd.imgvmlinuz至该目录

mkdir /var/lib/tftpboot/CentOS

cp /mnt/images/pxeboot/{initrd.img,vmlinuz}/var/lib/tftpboot/

cp /mnt/isolinux/isolinux.cfg/var/lib/tftpboot/pxelinux.cfg/default

cp ks.cfg /var/www/html/

 

 

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

 

default vesamenu.c32

#重新启动服务

service xinetd restart

service dhcpd restart

 

# ftp文件不需要做修改

 

# 使用命令system-config-kickstart

# 将命令生成的文件ks.cfg 复制到ftp目录下

cp /mnt /var/ftp/cdrom        #将光盘整个打包放置ftp目录下

chmod 744 ks.cfg

 

# ks.cfg 文件如下

#version=DEVEL

# Firewall configuration

# Install OS instead of upgrade

%post --interpreter=/bin/bash        #这里在最后一步中我定义了脚本，yum源

rm -rf /etc/yum.repos.d/*

echo ‘[yum]

service vsftpd restart

service dhcpd  restart

service xinetd restart

 

错误1： 使用system-config-kickstart命令之后无法选择软件

解决：必须在本地新建一个yum源    我这使用的是cd

[dvd]

name=dvd

baseurl=file:///var/ftp/cdrom

enabled=1

gpgcheck=0

错误2：CentOS时提示an error has occurred. - no valid devices were found

解决：更换光盘
