Linux设置开机自动挂载镜像文件

1.上传镜像

将镜像文件上传到服务器上（本例上传到/Data/software下）

2.挂载

mount -o loop /Data/software/rhel-server-7.6-x86_64-dvd.iso /mnt

3.查看文件格式

df -Th

Filesystem            Type     1K-blocks    Used Available Use% Mounted on
/dev/loop0            iso9660    4391278 4391278         0 100% /mnt

4.修改fstab文件

vi /etc/fstab 

#
# /etc/fstab

#
/Data/software/rhel-server-7.6-x86_64-dvd.iso /mnt iso9660 loop,defaults 0 0

5.测试

umount /mnt
mount -a
df -h
