createrepo

createrepo(8)															     createrepo(8)

NAME

       createrepo - Create repomd (xml-rpm-metadata) repository

SYNOPSIS

       createrepo [options] <directory>

DESCRIPTION

       createrepo is a program that creates a repomd (xml-based rpm metadata) repository from a set of rpms.

OPTIONS

       -u --baseurl <url>
	      Optional base url location for all files. (not used by any clients at this time)

       -o --outputdir <url>
	      Optional output directory (useful for read only media).

       -x --exclude <package>
	      File globs to exclude, can be specified multiple times.

       -i --pkglist <filename>
	      specify a text file which contains the complete list of files to include in the repository from the set found in the directory. File
	      format is one package per line, no wildcards or globs.

       -q --quiet
	      Run quietly.

       -g --groupfile <groupfile>
	      A precreated xml filename to point to for group information.
	      See examples section below for further explanation.

       -v --verbose
	      Run verbosely.

       -c --cachedir <path>
	      Specify a directory to use as a cachedir. This allows createrepo to create a cache of checksums of packages in  the  repository.	In
	      consecutive  runs  of  createrepo  over  the  same  repository  of files that do not have a complete change out of all packages this
	      decreases the processing time dramatically.

       --update
	      If metadata already exists in the outputdir and an rpm is unchanged (based on file size and mtime) since the metadata was generated,
	      reuse  the  existing  metadata  rather than recalculating it. In the case of a large repository with only a few new or modified rpms
	      this can significantly reduce I/O and processing time.

       -C --checkts
	      Don't generate repo metadata, if their timestamps are newer than its rpms.  This option decreases the  processing  time  drastically
	      again, if you happen to run it on an unmodified repo, but it is (currently) mutual exclusive with the --split option.

       --split
	      Run  in  split  media  mode.  Rather than pass a single directory, take a set of directories corresponding to different volumes in a
	      media set.

       -p --pretty
	      Output xml files in pretty format.

       -V --version
	      Output version.

       -h --help
	      Show help menu.

       -d --database
	      Generate sqlite databases for use with yum.

EXAMPLES

       Here is an example of a repository with a groups file. Note that the groups file should be in the same directory as the rpm packages  (i.e.
       /path/to/rpms/comps.xml).

       createrepo -g comps.xml /path/to/rpms

FILES

       repodata/filelists.xml.gz
       repodata/other.xml.gz
       repodata/primary.xml.gz
       repodata/repomd.xml

SEE ALSO

       yum (8) yum.conf (5)
