CentOS 5.5操作系统本来不支持 Logic MegaRAID SAS 1078驱动，安装UIT ContEx 1800时会找不到小盘安装系统，现特制定支持此raid卡的镜像系统盘，直接在isolinux.cfg中dd=cdrom:/raid驱动.img文件，提示选择设备驱动器，没有达到自动安装的目的，现改变方式来制作镜像盘，总结大致需要二步走，第一步，把驱动导入到initrd.img文件中，第二步，需要编辑ks.cfg的kickstart文件，将驱动文件中的.ko文件导入到/lib/modules/`uname -r`/updates/目录下，mkinitrd来实现，具体步骤如下：
1、挂载光驱
mount /dev/cdrom /mnt
2、创建临时目录
mkdir -p /root/iso/CentOS
3、提取需要的RPM包，正常安装好操作系统在/root目录下会有install.log文件，这个就是操作系统安装RPM包的记录，我们从这些记录中，将所需的RPM包从/mnt/CentOS中复制到/root/iso/CentOS里面去
#!/bin/bash
cd /root
awk ‘/Installing/{print $2}’ install.log | sed ‘s/^[0-9]*://g’ >package.txt
DVD=’/mnt/CentOS’
PACKDIR=’/root/package.txt’
NEW_DVD=’/root/iso/CentOS/’
while read LINE
do
cp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo “$LINE don’t cp…….”
done < package.txt
rm -f package.txt
4、把原镜像除了CentOS目录外的文件全部复制至/root/iso目录下
rsync -av –exclude=CentOS /mnt/ /root/iso
5、解开initrd.img文件（file /root/iso/isolinux/initrd.img查看是gzip文件）
mkdir /tmp/initrd
cd /tmp/initrd
gzip -dc /root/iso/isolinux/initrd.img | cpio -ivd
cd modules
gzip -dc modules.cgz | cpio -ivd
modules子目录中的modules.cgz是经过gzip压缩过的cpio包，将其解开。
6、解压raid卡驱动文件megasr-15.00.0120.2012-1-rhel50-U5-64.img文件（file megasr-15.00.0120.2012-1-rhel50-U5-64.img是dos软盘文件）
mkdir /tmp/megasr
mount -o loop /root/megasr-15.00.0120.2012-1-rhel50-U5-64.img /media
cp /media/* /tmp/megasr
cd /tmp/megasr/
gzip -dc modules.cgz | cpio -ivd
cp 2.6.18-194.el5/megasr.ko /tmp/initrd/modules/2.6.18-194.el5/x86_64/
cat modules.alias >> /tmp/initrd/modules/modules.alias
7、生成新的initrd.img文件
就像我们以前所做的，修改了源码包中的内容就势必再次打包恢复，这里我们需要把修改过的内容打包成一个initrd.img文件，不过这里要注意打包时的压缩格式，modules.cgz文件用的是crc格式，而initrd.img文件用的是newc格式，命令参数不要弄错。
cd /tmp/initrd/modules
find 2.6.18-53.el5 | cpio -o -H crc | gzip -9 > modules.cgz
rm -rf 2.6.18-53.el5
cd ..
find . | cpio -o -H newc | gzip -9 > /tmp/initrd.img
8、将打包好的initrd.img文件复制到 /root/iso/isolinux 目录
cp /tmp/initrd.img /root/iso/isolinux
9、在/root/iso目录下，并根据自己实际需要修改安装要求编辑ks.cfg文件

10、让ISO按照ks.cfg文件来执行安装，编辑/root/iso/isolinux目录下的isolinux.cfg文件，如下：
default kickstart
prompt 1
timeout 60
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
kernel vmlinuz
append initrd=initrd.img
label text
kernel vmlinuz
append initrd=initrd.img text
label ks
kernel vmlinuz
append ks initrd=initrd.img
label local
localboot 1
label memtest86
kernel memtest
append –
label kickstart
kernel vmlinuz
append text initrd=initrd.img ks=cdrom:/ks.cfg ramdisk_size=16384 ksdevice=eth0 console=tty0
11、生成comps.xml文件
cd /root/iso
createrepo -g repodata/*comps.xml /root/iso/
12、制作ISO
mkisofs -o /root/CentOS-5.5-x86_64-bin-DVD.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T /root/iso/
这样一个定制版的精简CentOS 5.5 就出来了！~~
