createrepo

Additional Notes

createrepo generates repository metadata for a directory of RPM packages. This metadata lets tools such as yum and dnf use the directory as a package repository.

Use it when building a local RPM repo, internal mirror, lab repo, or package staging area.

Syntax

createrepo [options] directory

Parameters

• directory: Directory containing RPM packages.
• options: Update, checksum, group, and metadata controls.

Common Options

• --update: Reuse existing metadata and update changed packages.
• -v: Verbose output.
• --database: Generate sqlite database metadata when supported.
• -g FILE: Include comps group metadata.
• --checksum TYPE: Select checksum type.

Examples

createrepo /srv/repo

Create metadata for RPMs in /srv/repo.

createrepo --update /srv/repo

Update metadata after adding packages.

find /srv/repo -name '*.rpm' | head

Check that packages exist before generating metadata.

Practical Notes

• The repository still needs to be served or referenced by a repo file.
• Run createrepo --update after adding or removing RPMs.
• Newer systems may use createrepo_c, a faster C implementation.
