Configuration file

DNF by default uses the global configuration file at /etc/dnf/dnf.conf and all *.repo files found under /etc/yum.repos.d. The latter is typically used for repository configuration and takes precedence over global configuration.

The configuration file has INI format consisting of section declaration and name=value options below each on separate line. There are two types of sections in the configuration files: main and repository.

Main section defines all global configuration options. The repository sections define the configuration for each (remote or local) repository. The section name of the repository in brackets serve as repo ID reference and should be unique across configuration files. The minimal repository configuration file should aside from repo ID consists of baseurl, metalink or mirrorlist option definition.
