Editor to share with you how to set the iso file as the local yum source for CentOS, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Problems and ideas

Because the server cannot access the Internet, you can only upload the image file of the iso system to the server, and then set the iso file as the local yum source. Only in this way can yum be updated and installed.

Solution and steps

Upload iso files using the zmodem protocol, which limits the size of uploaded files to a maximum of 4G files. Therefore, you need to split the files less than 4G first, and then merge the files on the server.

Split file split-b 3072m CentOS-7-x86_64-DVD-1810.iso CentOS-7-x86_64-DVD-1810.iso-

View the split file:

Use the rz command in the zmodem protocol to upload files to the server, and then merge the files.

Merge file cat CentOS-7-x86_64-DVD-1810.iso-* > CentOS-7-x86_64-DVD-1810.iso mount image mkdir / mnt/isomount-o loop CentOS-7-x86_64-DVD-1810.iso / mnt/iso

Verify image mount:

Df-h configure yum source

Back up the Yum source configuration:

Cd / etc/yum.repos.d/rename .repo .repo.bak *

Create a new yum local source configuration:

Vim CentOS-Local.repo

Specific configuration content:

[local] name=CentOS-Localbaseurl= file:///mnt/isogpgcheck=1enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
