How to make use of yum s cache files

1.Use yum caching.

By default, the current version of yum will delete the files after successfully installing the package. This reduces the disk space occupied by yum. You can turn on caching so that yum will keep the files in the cache directory.

Caching brings a lot of benefits:

Yum's performance could be improved.

You can run yum operations offline and use only the cache.

You can copy the packages in the cache for backup.

By default, yum keeps temporary files in the var cache yum directory, and each repository has its own subdirectory. The packages subdirectory in the repository directory contains the cached packages. For example, the directory var cache yum development packages contains packages from the development repository.

2.Enable yum caching.

keepcache=1

When the cache is turned on, each yum operation may be taken from the repository package data. To ensure that the cache contains package data, run an operation such as list or search when caching is enabled to ** the package data without affecting the system.

3.Use yum in cache-only mode

To execute yum without a network, you can use the -c option as long as caching is enabled. This way yum doesn't check the repositories on the network and only uses the cache. In this mode, yum can only install packages that have been cached and cached.

Yum (Yellow Dog Updater, Modified) is a front-end shell package manager in Fedora and Redhat, as well as SUSE. Based on rpm package management, it can automatically install rpm packages from a specified server, can automatically handle dependencies, and install all dependent software packages at one time, without cumbersome time and again.

The steps to clean up are as follows:

2. Uninstall software that is not commonly used, which can reduce the space occupied by the phone.

3. When you don't need to use the software, close the software, and the background operation will not only use traffic, but also occupy the memory of the mobile phone when you know the pulse and run.

4. Don't easily update the system on your mobile phone, many new mobile phones are more likely to have insufficient memory on your mobile phone after updating the new system, and your mobile phone will respond more slowly.
