需求：
1.全自动安装的centos6.5安装镜像，实现非技术人员能够容易安装linux系统的需求
2. 系统自带云知声医疗系统后台服务程序安装包及其依赖程序
解决方案：
1. 安装镜像自带Anaconda-Kickstart配置文件，并指定其配置
2. 自定义Anaconda-Kickstart配置文件指定其所需自动化过程
准备：
1. centos6.5原始ISO文件 （CentOS-6.5-x86_64-bin-DVD1.iso）
2. 使用centos6.5原始ISO文件安装系统后的安装日志（/root/install.log）
3. Anaconda-Kickstart配置文件 (ks.cfg)
4.云知声医疗安装包(yzs)
过程：
挂载centos6.5原始安装镜像
➜ iso mkdir centos6.5
➜ iso mkdir centos6.5_new
➜ iso sudo mount CentOS-6.5-x86_64-bin-DVD1.iso centos6.5_new
➜ iso rsync -a --exclude=Packages/ --exclude=repodata/ centos6.5/ centos6.5_new/
➜ iso sudo mkdir centos6.5_new/{Packages,repodata}
仅将需要安装的软件包集成到镜像
➜ iso cat copy.sh
#!/bin/bash
awk '/Installing/{print $2}' install.log | sed 's/^*://g' >>package.txt
DVD='/home/yunwei/iso/centos6.5/Packages'
PACKDIR='./package.txt'
NEW_DVD='/home/yunwei/iso/centos6.5_new/Packages'
while read LINE
do
cp ${DVD}/${LINE}*.rpm ${NEW_DVD} || echo "$LINE don't cp......."
done < package.txt
rm -f package.txt
➜ iso sudo sh copy.sh #这里可以将想要安装的rpm放到centos6.5_new/Packages，然后在ks配置文件中配置后安装系统时便可自动安装
#可根据实际需求添加相应的软件包
➜ iso sudo cp centos6.5/repodata/b4e0b9342ef85d3059ff095fa7f140f654c2cb492837de689a58c581207d9632-c6-x86_64-comps.xml centos6.5_new/repodata/c6-x86_64-comps.xml
➜ iso declare -x discinfo=`head -1 .discinfo`
➜ iso sudo createrepo -u "media://$discinfo" -g repodata/c6-x86_64-comps.xml centos6.5_new
将ks.conf 集成到initrd.img
➜ iso mkdir initrd-new
➜ iso cp centos6.5_new/isolinux/initrd.img initrd.img.xz
➜ iso xz --format=lzma initrd.img.xz --decompress
➜ iso cd initrd-new
➜ initrd-new cpio -ivdum < ../initrd.img
➜ initrd-new cp ../ks.cfg var/ks.cfg
➜ initrd-new find . -print |cpio -o -H newc | xz --format=lzma > ../initrd-new.img
➜ initrd-new cd ..
➜ iso sudo cp initrd-new.img centos6.5_new/isolinux/initrd.img
修改引导配置，使其读取ks.cfg配置文件
➜ iso vim centos6.5_new/isolinux/isolinux.cfg
18 label linux
19 menu label ^Install or upgrade an existing system
20 menu default
21 kernel vmlinuz
22 append ks=file:/var/ks.cfg initrd=initrd.img text
23 label vesa
将云知声医疗安装包放如镜像
➜ iso sudo cp -r yzs centos6.5_new
生成新的ISO镜像文件
➜ iso sudo xorriso -as mkisofs \
-D -r -J -joliet-long -l -V "Custom Install CD" \
-b isolinux/isolinux.bin \
-c isolinux/boot.cat \
-iso-level 3 -no-emul-boot -partition_offset 0 -boot-load-size 4 -boot-info-table \
-isohybrid-mbr --interval:local_fs:0s-15s:zero_mbrpt:'CentOS-6.5-x86_64-bin-DVD1.iso' \
-o Centos6.5-yzs.iso centos6.5_new
Centos6.5-yzs.iso 即为新的镜像。
