1.將文件上傳到服務器上（本例上傳到/Data/software下）
2.掛載
mount -o loop /Data/software/rhel-server-7.6-x86_64-dvd.iso /mnt
3.使用df -T查看鏡像文件格式（一般都是iso9660）
[root@zabbix_test ~]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/rhel-root xfs 52403200 1054636 51348564 3% / devtmpfs devtmpfs 4074828 0 4074828 0% /dev tmpfs tmpfs 4086896 0 4086896 0% /dev/shm tmpfs tmpfs 4086896 8740 4078156 1% /run tmpfs tmpfs 4086896 0 4086896 0% /sys/fs/cgroup /dev/sda1 xfs 508580 128008 380572 26% /boot /dev/mapper/rhel-Data xfs 43498752 4424928 39073824 11% /Data tmpfs tmpfs 817380 0 817380 0% /run/user/0 /dev/loop0 iso9660 4391278 4391278 0 100% /mnt
4.編輯fstab文件
[root@zabbix_test ~]# vi /etc/fstab # # /etc/fstab # Created by anaconda on Tue Oct 27 10:35:21 2020 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/rhel-root / xfs defaults 0 0 /dev/mapper/rhel-Data /Data xfs defaults 0 0 UUID=4394cca8-82c3-4ee7-9cd7-c90a71fb65ef /boot xfs defaults 0 0 /dev/mapper/rhel-swap swap swap defaults 0 0 /Data/software/rhel-server-7.6-x86_64-dvd.iso /mnt iso9660 loop,defaults 0 0
5.下載/mnt
umount /mnt
6.使用mount -a測試是否OK
[root@zabbix_test ~]# mount -a mount: /dev/loop0 is write-protected, mounting read-only [root@zabbix_test ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 50G 1.1G 49G 3% / devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 8.6M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda1 497M 126M 372M 26% /boot /dev/mapper/rhel-Data 42G 4.3G 38G 11% /Data tmpfs 799M 0 799M 0% /run/user/0 /dev/loop0 4.2G 4.2G 0 100% /mnt
