客户采购200台联想服务器，现在需要安装系统， 一台一台的用优盘安装，显然不是最佳办法，PXE安装肯定是首选，但是还是得一台一台配置阵列，这样，明显效率不高。我百度、谷歌了下，发现pxe下可以配置阵列，但是都比较复杂，大致思路都是先用一个类似于live os引导进去，先执行相应的命令，然后再重启。再次引导pxe 进行安装，这显然也很麻烦，我整理了一套非常简单的方法。

原理：利用kickstart文件中的pre执行命令，在安装前调用阵列卡的配置程序，用命令配置阵列。配置完阵列，然后安装系统，都不用重启，也不用引导精简版的Linux。

安装PXE服务器的文档，充斥在全网的各个角落，我就不写了，我这里只贴出我的配置文件作为参考

1，dhcp配置文件

```

option space PXE;

option PXE.mtftp-ip code 1 = ip-address;

option PXE.mtftp-cport code 2 = unsigned integer 16;

option PXE.mtftp-sport code 3 = unsigned integer 16;

option PXE.mtftp-tmout code 4 = unsigned integer 8;

option PXE.mtftp-delay code 5 = unsigned integer 8;

option client-system-arch code 93 = unsigned integer 16;

allow booting;

allow bootp;

default-lease-time 3600;

max-lease-time 21600;

subnet 192.168.70.0 netmask 255.255.255.0{

range 192.168.70.10 192.168.70.200;

option routers 192.168.70.1;

class "pxeclients" {

match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";

next-server 192.168.70.2;

if option client-system-arch = 00:07 or option client-system-arch = 00:09 {

filename "uefi/bootx64.efi";

} else {

filename "pxelinux.0";

}

}

}

```

2，kickstart配置文件

```

wget http://192.168.70.1/rdconfig/rdconfig.sh

cp rdconfig.sh /tmp/

chmod a+x /tmp/rdconfig.sh

/tmp/rdconfig.sh

sleep 12

%end

#config yum

wget http://192.168.70.1/script/script.sh

cp script.sh /tmp/

chmod a+x /tmp/script.sh

/tmp/script.sh

rm -fr /tmp/script.sh

%end

```

3，rdconfig配置文件 配置raid

```

wget http://192.168.70.1/rdconfig/storcli /

sleep 3

cp /storcli /usr/bin

chmod +x /usr/bin/storcli

sleep 3

storcli /c0 add vd type=raid5 size=all names=raid5 drive=62:0-6

sleep 3

storcli /c0/e62/s7 add hotsparedrive

```

4，自动配置yum脚本

```

#!/bin/bash

#mount nfs

mkdir /yumdata

mkdir /tmp/nfs

mount -t nfs 192.168.70.1:/iso /tmp/nfs

cp -vr /tmp/nfs/centos76/* /yumdata

#config yum

cd /etc/yum.repos.d/

mkdir bak

mv *.repo bak

> local.repo

cat >> local.repo << "EOF"

[local]

name=local

baseurl=file:///yumdata

enabled=1

gpgcheck=0

EOF

umount /tmp/nfs

```

5，grub.cfg 配置文件

```

set default="0"

function load_video {

insmod efi_gop

insmod efi_uga

insmod video_bochs

insmod video_cirrus

insmod all_video

}

load_video

set gfxpayload=keep

insmod gzio

insmod part_gpt

insmod ext2

set timeout=10

### END /etc/grub.d/00_header ###

search --no-floppy --set=root -l 'CentOS 7 x86_64'

### BEGIN /etc/grub.d/10_linux ###

menuentry 'Install CentOS 7.6' --class fedora --class gnu-linux --class gnu --class os {

linuxefi uefi/vmlinuz inst.repo=http://192.168.70.1/centos76/ inst.ks=http://192.168.70.1/kscfg/ct76ks.cfg

initrdefi uefi/initrd.img

}

```

备注：配置阵列的命令中用到的eid 和sid 需要提前查看。配置好脚本，服务器开机等着就行，kickstart还能干更多的事，来简化配置工作。
