Overview

YUM (Yellowdog Updater, Modified) allows you to easily download and install software, and simplifies your installations on a CVM instance, saving you time and efforts. With it, you only need to run the yum command to install software in the CentOS environment. Tencent Cloud provides a YUM repository so you can directly install software packages without adding sources.
