Yum Cache Generation

Yum cache generation is the process of creating a local metadata cache for package repositories. This allows the package manager to resolve dependencies and install software without needing to query the remote mirrors for every operation.

Command

The standard command to generate the cache is:

yum makecache

This command downloads the necessary metadata from the configured repositories and stores it locally on the system^[600-developer__docker__yum-aliyun.md].

Workflow Context

In a typical workflow involving the modification of repository sources, cache generation is performed after the new repository configuration file has been downloaded. For example, after switching to an Aliyun mirror source, running yum makecache is the final step to ensure the system recognizes the available packages^[600-developer__docker__yum-aliyun.md].
