普通是 rar, zip, tar, 7z 仅存档模式在使用时也需要先解压再使用, 打包成 iso 镜像后可以直接挂载使用. 可以节省解压时间, 硬盘空间

制作 iso 镜像会搜到两个工具名称 mkisofs 和 genisoimage, 其实最早时候 Linux 系统使用 cdrtools 工具来管理 iso 及光盘, mkisofs 是 cdrtools 里面的一个工具, 后来 cdrtools 更改了授权许可, 从 GPL 修改为 CDDL 许可, 开源社区又推出了一套基于 GPL 的工具, cdrkit, mkisofs 也被 genisoimage 代替, 现在系统中的 mkisofs 实际是 genisoimage 的软连接

[root@server ~]# whereis mkisofs
mkisofs: /usr/bin/mkisofs /usr/share/man/man1/mkisofs.1.gz

[root@server ~]# ls -l /usr/bin/mkisofs
lrwxrwxrwx. 1 root root 25 Mar 29 05:32 /usr/bin/mkisofs -> /etc/alternatives/mkisofs
[root@server ~]# ls -l /etc/alternatives/mkisofs
lrwxrwxrwx. 1 root root 20 Mar 29 05:32 /etc/alternatives/mkisofs -> /usr/bin/genisoimage

[root@server ~]# whereis genisoimage
genisoimage: /usr/bin/genisoimage /usr/share/man/man1/genisoimage.1.gz
[root@server ~]# ls -l /usr/bin/genisoimage
-rwxr-xr-x. 1 root root 521240 Oct 31  2018 /usr/bin/genisoimage

安装工具

yum install genisoimage -y

制作镜像

一般情况下制作文件需要添加 -lJR 参数, 没添加时文件名会被裁剪并转为全大写名称 ISO-9660 标准

genisoimage -lJR -o output_image.iso directory_name

使用 7z 解压镜像

用 7z 查看 iso 文件内容

7z l acesheep.iso 

7z 解压镜像可以设置解压位置, 命令行下比挂载方便

7z x acesheep.iso -oAceSheep-Folder
