How to build RPM packages as a regular user

Install the necessary packages as root:

sudo yum install rpmdevtools rpm-build redhat-rpm-config

Initialize the directory hierarchy for your custom build RPM packages as a regular user:

rpmdev-setuptree

Optionally add additional attributes into ~/.rpmmacros, e.g.:

echo '%packager Your Name <your.name@foo.bar>' >> ~/.rpmmacros

Use rpmbuild to build RPM from a source RPM or from a SPEC file:

rpmbuild --rebuild package.src.rpm
rpmbuild -bb package.spec
