RHEL6.6 PXE安装-基于VMWare WorkStation

///////////第一部分：安装安装服务器

1.先安装一台RHEL6.6的服务器A(地址为192.168.139.132)，作为安装服务器。这样后面的机器就可以指向这台服务器进行自动安装

2.在A上安装http服务器

3.将OS的文件拷贝到/var/www/html/rhel6.6

4.在A上安装createrepo工具/rhel6.6

5.在A上建立repo。指向http://192.168.139.132

6.准备kickstart文件

修改配置：由于安装服务器是用的cdrom安装，但后面的服务器需要从http服务上安装，所以需要修改

#cdrom
url --url http://192.168.139.132/rhel6.6/
将cdrom注释掉，增加一条url指令

当然也可以把fireware和selinux关掉

[root@localhost ~]# cp anaconda-ks.cfg /var/www/html/
[root@localhost ~]# chmod 777 /var/www/html/anaconda-ks.cfg

# Kickstart file automatically generated by anaconda.

#version=DEVEL

///////////////第二部分：安装必要工具/////////////

1.安装syslinux

yum install syslinux

2.安装dhcp

yum install dhcp

需要进行配置

vi /etc/dhcp/dhcpd.conf

内容如下:

ddns-update-style interim;
ignore client-updates;

allow booting;
allow bootp;

class "pxeclients"{
match if substring(option vendor-class-identifier,0,9) = "PXEClient";
filename "pxelinux.0";
next-server 192.168.139.132;
}

subnet 192.168.139.0 netmask 255.255.255.0 {
option routers 192.168.139.1;
option subnet-mask 255.255.255.0;
option time-offset -18000; # Eastern Standard Time
range dynamic-bootp 192.168.139.2 192.168.139.254;
default-lease-time 216000;
max-lease-time 432000;
}

service dhcpd start

chkconfig dhcpd on

3.安装tftp-server

yum install tftp-server

修改配置文件vi /etc/xinetd.d/tftp将disable由yes改为no

disable = no

拷贝启动引导文件

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

cp /usr/share/syslinux/vesamenu.c32 /var/lib/tftpboot/

cp /var/www/html/rhel6.6/images/pxeboot/{initrd.img,vmlinuz} /var/lib/tftpboot/

mkdir /var/lib/tftpboot/pxelinux.cfg

cp /var/www/html/rhel6.6/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

修改/var/lib/tftpboot/pxelinux.cfg/default的配置:

default linux-ks
#prompt 1
timeout 10

display boot.msg

menu background splash.jpg
menu title Welcome to Red Hat Enterprise Linux 6.6!
menu color border 0 #ffffffff #00000000

menu color scrollbar 0 #ffffffff #00000000

label linux-ks
menu label ^Install or upgrade an existing system with kickstart
menu default
kernel vmlinuz
append initrd=initrd.img ks=http://192.168.139.132/anaconda-ks.cfg

启动服务

service xinetd start

chkconfig xinetd on

///////////////第三部分：批量安装其他服务器

1.在VMWare中建立一个空白服务器。

2.启动空白服务器，此时空白服务器会自动找到安装服务器。整个过程无需人工干预

问题解决:

1.出现The storage may contain data的警告，这时需要人工干预。想去这个警告，进行全自动安装。

在ks.cfg中加入

# Clear the Master Boot Record
zerombr

2.出现ks.cfg无法访问的问题

确保ks.cfg的访问权限没问题
