openEuler

Introduction to openEuler and Software Management

openEuler is an open-source operating system project incubated and operated by the OpenAtom Foundation, aiming to provide powerful operating system support for servers and cloud computing environments. openEuler is led by Huawei, a Chinese company, and supported by the community. The current openEuler system is based on the Linux kernel and supports Kunpeng, RISC-V, and various other processors, fully unleashing the potential of computing chips. It is an efficient, stable, and secure open-source operating system built by global open-source contributors and is suitable for database, big data, cloud computing, artificial intelligence, and other application scenarios.

openEuler uses the DNF tool to manage RPM software packages, query package information, fetch packages from specified repositories, automatically handle dependencies for package installation and removal, and system updates. openEuler is configured and manages software sources through the /etc/yum.repos.d/openEuler.repo file.
