A solution to the problem of "couldn't open file /mnt/repodata/repomd.xml"

We are using yum install When installing required packages , Would report such a mistake .

  My solution is ：

echo '
[local]
name=local
baseurl=file:///mnt
enabled=1
gpgcheck=0 ' > local.repo

then ：

mount /dev/cdrom /mnt 
yum clean all && yum repolist 

 

Last yum You can use it .
