- Create a basic repository
- Create a repository that allows clients to install groups
- Modify repodata to identify which packages are security related
Install the required packages
createrepopackages on the registered system.
# yum install yum-utils createrepo
Create a basic local repository
<repo-id> to the repository you intend to sync
Sync all the packages from a specified repository to a specified directory
# reposync --gpgcheck -l --repoid=<repo-id> for example: # reposync --gpgcheck -l --repoid=rhel-6-server-rpms --download_path=/var/www/html
In the targeted directory, there will be a new directory named after the Repository ID. All the downloaded packages will be inside this directory.
# cd /var/www/html/<repo-id> # createrepo -v /var/www/html/<repo-id>
Create a local repository that allows clients to use groups
How to download all the metadata for the repository that is being synced which will allow the use of various plugins such as 'yum groupinstall'
On RHEL6 and later, reposync supports the
--downloadcompsoptions. For example:
# reposync --gpgcheck -l --repoid=repo-id --downloadcomps --download-metadata for example: # reposync --gpgcheck -l --repoid=rhel-6-server-rpms --download_path=/var/www/html --downloadcomps --download-metadata
To have access to the group data for the newly synced repo, please run the
createrepocommand as follows:
# cd /var/www/html/<repo-id> # createrepo -v /var/www/html/<repo-id>/ -g comps.xml
Modify the repodata to define which packages are security related.
These steps require that the createrepo command has already been run.
# yum clean all # yum list-sec # find /var/cache/yum/ -name updateinfo.xml ##For RHEL 5 use '-name *updateinfo.xml*'
From the find command above, identify the
updateinfo.xmlthat matches the
<repo-id>that you ran
reposyncagainst and move that file into your repodata directory.
# mv updateinfo.xml /var/www/html/<repo-id>/repodata/updateinfo.xml # modifyrepo /var/www/html/<repo-id>/repodata/updateinfo.xml /var/www/html/<repo-id>/repodata
- To keep the sync current, for example, cronjobs can be used. The
--updateto efficiently update existing repositories.
- The locally created repository is typically used by other RHEL clients via LAN, for example via HTTP/HTTPS (for example provided by the apache webserver which is part of RHEL), via FTP (i.e. vsftpd) or NFS (nfs-utils package). Share this local repository with the offline systems to update the offline systems.
reposyncutility can only mirror repositories which the system is entitled to.

- For RHEL 7.7+, The Red Hat Customer Portal assumes that if all Red Hat provided CDN repositories are disabled the system lacks access to the latest content, and will not show errata information. If you need/want to see a systems errata information in the Red Hat Customer Portal, subscription manager must have at least one official redhat repository enabled. Note that only the enabled repositories are considered as part of the errata applicability calculation.
- You can create a copy of a directory which is prepared as YUM repository, and then without adding further packages to that repo have clients use the repo as a "frozen" set of packages. Creating such copies needs extra storage, but as the files are duplicates of existing packages, as long as the involved files are on the same file system,
hardlinkscan be used to then reduce the requirements.
Red Hat provides a utility called
reposync which can be used to download the packages from the CDN. In order to download all packages from a specific channel, the system should be subscribed to that channel. If the system is not subscribed to the required channel then
reposync will not be able to download and sync those packages on local system.

--update, refer to bz1434369 for details.
