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

) |9 ?' ]  w, K) V* l# K# z

方法2：#cat /dev/cdrom >;/root/centos6.3.iso

/ x4 P/ B6 C9 X

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。
