How do I configure a local yum repository in a CentOS7 system environment?
After minimizing the installation of CentOS7 on the virtual machine, there are really few tools in it, so add cdrom as the local yum repository
1. Create a mount point for cdrom
Mkdir / mnt/cdrom
2. Modify fstab and automatically mount cdrom on boot, adding the following line
/ dev/cdrom / mnt/cdrom iso9660 defaults 0 0
3. Mount cdrom
Mount-a
4. Move the existing repo files to the backup folder
Cd / etc/yum.repo/
Mkdir bak
Mv .repo bak
5. Create cdrom.repo
Vi cdrom.repo
[cdrom] name=CentOS-7-CDROM baseurl= file:///mnt/cdrom enabled=1 gpgcheck=0
6. Testing
Yum makecache
