Mirroring the Condor YUM Repository
Motivation
Some of our collaborators in Europe or other continents would like to keep a locally available mirror for the ease of updating their YUM installs of Condor
in large pools. Since all of the Condor YUM repository is already publicly available, there is no enforceability to restrict the mirroring of it. Hence it is made available.
UW-Madison Server Configuration
On parrot.cs.wisc.edu, in the /etc/rsyncd.conf file, you will find these
configurations. They were set up by the CSL at the Condor Team's request and are maintained by the CSL. The Condor Team uses the usual channels to communicate with the CSL when this configuration needs changing. There should
be nothing surprising or confidential in this configuration.
[condor-yum-development] path=/p/condor/public/html/yum/development read only = true uid=nobody gid=nobody [condor-yum-stable] path=/p/condor/public/html/yum/stable read only = true uid=nobody gid=nobody [condor-yum-repo.d] path=/p/condor/public/html/yum/repo.d read only = true uid=nobody gid=nobody
Mirror Site Actions
Once the mirror has happened at a site, this is what the mirroring site
needs to do. These changes allow YUM requests against the mirror site
to get the right files from the right place.
The directory structure of the YUM repo is:
<path>/yum/development- Contains Development Repositories/rhel4- The Rhel 4 release of Condor/condor-7.5.-*- The development version RPM files for RHEL4/repodata - The index files for this portion of the repo.- =/filelists.xml.gz
/other.xml.gz/primary.xml.gz/repomd.xml
/rhel5- The Rhel 5 release of Condor/condor-7.5.-*- The development version RPM files for RHEL5/repodata - The index files for this portion of the repo.- =/filelists.xml.gz
/other.xml.gz/primary.xml.gz/repomd.xml
/stable - Contains Stable Repositories
/rhel4- The Rhel 4 release of Condor/condor-7.4.-*- The stable version RPM files for RHEL4/repodata - The index files for this portion of the repo.- =/filelists.xml.gz
/other.xml.gz/primary.xml.gz/repomd.xml
/rhel5 - The Rhel 5 release of Condor
/condor-7.4.-*- The stable version RPM files for RHEL5/repodata- The index files for this portion of the repo./filelists.xml.gz/other.xml.gz/primary.xml.gz/repomd.xml
/repo.d - Store repo files that describe the yum repo locations
/condor-development-rhel4.repo- A Repo Description File/condor-development-rhel5.repo- A Repo Description File/condor-stable-rhel4.repo- A Repo Description File/condor-stable-rhel5.repo- A Repo Description File
Now we must modify the repo files to point to the mirrored repository.
- Modify the store repo files to contain the new url to the RPMs. The files
that must be modified are listed. The attribute which needs changing is the
baseurl attribute in each of these files. This must point to a fully
qualified URL at the local mirror site.
<path>/yum/repo.d/condor-development-rhel4.repo<path>/yum/repo.d/condor-development-rhel5.repo<path>/yum/repo.d/condor-stable-rhel4.repo<path>/yum/repo.d/condor-stable-rhel4.repo
- Update index files by executing the following commands. This will
create/update the index files for each directory.
> cd <path>/yum > createrepo stable/rhel4 > createrepo stable/rhel5 > createrepo development/rhel4 > createrepo development/rhel5
- Optionally create a
<path>/yum/index.htmlweb page which describes installation directions with links to the mirrored repository. An example of such a page is here. Once this page is created, its URL should be advertised so people can easily find and use the mirror. Note: Do not copy the example page verbatim, as it will point to UW-Madison's YUM repository!
