centos定制
centos定制
centos定制主要是制作合适自己的iso系统进行批量安装,此例制作出来的iso是一个lnmp环境,其中nginx、php为自己打包的rpm包。iso制作方法参照了http://www.lampbo.org/linux-xuexi/linux-advance/diy-centos6.html
1、安装centos6,本例使用的是centos6.4-minimal系统
1
|
wget http:
//mirrors
.sohu.com
/centos/6
.4
/isos/x86_64/CentOS-6
.4-x86_64-minimal.iso
|
2、安装制作工具
1
|
yum -y
install
anaconda repodata createrepo
mkisofs
|
3、挂载光盘
1
2
|
mkdir
/mnt/cd1
mount
/dev/cdrom
/mnt/cd1
|
4、 创建ios制作目录,将光盘内容拷贝到该目录
1

3
|
mkdir
/mnt/centos
cp
-rp
/mnt/cd1/
*
/mnt/centos
cp
/mnt/
.discinfo
/mnt/
.treeinfo
/mnt/centos
|
5、 配置kickstart文件,实现系统定制化安装依靠该文件

6、将需要安装的rpm包到/mnt/centos/Packages目录下
7、修改isolinux.cfg启动文件

vi
/mnt/centos/isolinux/isolinux
.cfg
label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append ks=cdrom:
/isolinux/ks
.cfg initrd=initrd.img
|
8、修改comps.xml文件,每次在/mnt/centos/Packages目录添加rpm包后需要更新此文件

cd
/mnt/centos
mv
/mnt/centos/repodata/
*-comps.xml comps.xml
ls
/mnt/centos/repodata/
|
grep
-
v
“comps.xml”|
xargs
-I
rm
-f {}
createrepo -g
/mnt/centos/repodata/comps
.xml
mv
/mnt/centos/repodata/
*-comps.xml comps.xml
declare
-x discinfo=`
head
-1
/mnt/centos/
.discinfo`
createrepo -u
"media://$discinfo"
-g repodata
/comps
.xml
/mnt/centos
|
9、生成iso文件
1
2
|
cd
/mnt/centos
mkisofs
-o centos6.4-sylee-x86_64.iso -b isolinux
/isolinux
.bin -c isolinux
/boot
.
cat
-no-emul-boot -boot-load-size 4 -boot-info-table -R -J -
v
-T
/mnt/centos/
