dnf与yum的区别?
DNF(Dandified YUM)是由Aleš Kozumplík在Fedora项目的支持下创建的。DNF最初是为了解决YUM的一些性能和依赖性问题而设计的。YUM(Yellowdog Updater, Modified)是一个较早的包管理器,它在Fedora、CentOS等Red Hat Linux派生系统中被广泛使用。
DNF引入了几项改进和新特性:
- 改进的依赖解析:DNF使用了一个新的解决方案库libsolv,这是从openSUSE项目借鉴而来的,它提供了更快且更可靠的依赖解析。
- 性能优化:DNF旨在提高性能,特别是在处理大型软件库时。
- 更干净的代码基础:DNF的代码库被重新组织和简化,使其更容易维护和扩展。
- 支持新特性:例如更好的API、软件回滚和插件支持等。
虽然YUM在很多系统中仍然可用,但DNF被设计来逐步替代YUM,因为它提供了更多现代化的特性和更佳的性能。从Fedora 22开始,DNF成为了默认的包管理器。其他基于Red Hat的发行版也逐渐采用DNF替代YUM。
