Linux系统封装成iso文件

#安装所需软件包


根据root下的install.log文件,得到安装的软件包
awk '/Installing/{print $2}' install.log |sed 's/^[0-9]*://g' >/root/packages.list

[root@localhost www]# mkdir centOS6.32bit
[root@localhost html]# rsync -a --exclude=Packages centOS6 centOS6.32bit/
[root@localhost html]# pwd
/var/www/html
[root@localhost html]# mkdir centOS6.32bit/Packages


复制软件包
for fileRpm in `cat packages.list`; do cp -r /var/www/html/centOS6/Packages/$fileRpm* /var/www/html/centOS6.32bit/centOS6/Packages ; done

按照执行就可以
[root@localhost centOS6]# cd /var/www/html/centOS6.32bit/centOS6
[root@localhost centOS6]# createrepo -g repodata/*-comps.xml /var/www/html/centOS6.32bit/centOS6

Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@localhost centOS6]# declare -x discinfo=`head -1 .discinfo`
[root@localhost centOS6]# createrepo -u "media://$discinfo" -g repodata/*-comps.xml /var/www/html/centOS6.32bit/centOS6/

Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@localhost centOS6]#


[root@localhost centOS6]# createrepo -g repodata/*-comps.xml /var/www/html/centOS6.32bit/centOS6/

按照执行就可以


-o 输出iso文件位置

[root@localhost home]# /usr/bin/implantisomd5 CentOS-6.3-i386-bin-DVD1.iso
Inserting md5sum into iso image...
md5 = 219c7e289d01cdb84cf99de8b3e04503
Inserting fragment md5sums into iso image...
fragmd5 = a9265bee4498b5e93a2e84a58235458cad3651caa37f41da397155e6abe1
frags = 20
Setting supported flag to 0
[root@localhost home]#

二、 linux制作iso镜像方法总结

把/dev/cdrom目录制作为镜像，名字为/root/centos6.3.iso
方法1：dd if=/dev/cdrom of=/root/centos6.3.iso
方法2：#cat /dev/cdrom >;/root/centos6.3.iso
方法3：mkisofs -r -o centos6.3.iso /dev/cdrom
方法4：cp -r /home/user name.iso
生成iso镜像以后，就可以用linux下的DVD进行刻录，刻录为DVD光盘了。

前提是已安装好的linux系统都是rpm包安装，这样才能根据/root/install.log文件定制出iso文件。
