Yum/Apt Package Managers: Powerful Tools for Linux Software Installation

To install software on Linux, Yum or Apt package managers are required, which automatically handle downloading, dependencies, and updates. Yum is used for RHEL/CentOS/Fedora, managing .rpm packages. Its core commands include: `sudo yum install/search/remove/clean all`. Software sources are located in `/etc/yum.repos.d/`, and additional sources can be added via `epel-release`. Apt is for Debian/Ubuntu, managing .deb packages. Its commands are: `sudo apt install/search/remove/clean`. Before using `upgrade`, the sources must be updated with `update` first. Software sources are in `/etc/apt/sources.list` and `/etc/apt/sources.list.d/`, and Ubuntu users can switch to domestic mirror sources. Both managers rely on correct software sources. Beginners should first run `cat /etc/os-release` to confirm the distribution. If dependency issues occur, update the sources first; if software sources are incorrect, back them up and test. In summary: Use Yum for RHEL/CentOS/Fedora and Apt for Debian/Ubuntu. Familiarity is achieved through practice.
