封装linux系统成iso文件 #安装所需软件包 yum -y install createrepo mkisofs anaconda-runtime   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 491/491 - Packages/abrt-addon-ccpp-2.0.8-6.el6.centos.i686.rpm                   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/ 488/488 - Packages/glibc-2.12-1.80.el6.i686.rpm                                  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/ 488/488 - Packages/glibc-2.12-1.80.el6.i686.rpm                                  Saving Primary metadata Saving file lists metadata Saving other metadata [root@localhost centOS6]# echo $?        #测试上条命令是否运行成功

按照执行就可以 mkisofs -R -J -T -r -l -d -joliet-long -allow-multidot  -allow-leading-dots -no-bak -o/home/CentOS-6.3-i386-bin-DVD1.iso  -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot  -boot-load-size 4 -boot-info-table /var/www/html/centOS6.32bit/centOS6 -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]# 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。
