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
```

%end

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。
