RHEL_8.1-挂载镜像
上传ISO到本地
mkdir /software
ll /software/

-rw-r--r--. 1 root root 7851737088 May 30 21:52 rhel-8.1-x86_64-dvd.iso
手动挂载
mkdir /media/cdrom -p
mount -t iso9660 -o loop /software/rhel-8.1-x86_64-dvd.iso /media/cdrom
自动挂载
vim /etc/fstab
/software/rhel-8.1-x86_64-dvd.iso /media/cdrom iso9660 defaults,ro,loop 0 0
#然后再mount -a 挂载
#但是或许会出现如下问题：
cat /etc/fstab |grep iso
#/root/rh401-pub.iso /mediaiso9660 defaults,ro,loop 0 0
mount -a
#mount: wrong fs type, bad option, bad superblock on /dev/loop0,missing codepage or other error
#In some cases useful info is found insyslog - try dmesg | tailor so
#提示错误的文件系统类型，so，可能iso镜像文件并不是一般的iso9660格式的，如何查看呢？
#1.手动挂载
#2.查看系统类型 udf
mount -o loop /software/rhel-8.1-x86_64-dvd.iso /media/cdrom
