How to setup repository

• When a package is added/removed from a repository, you can update the repodata so that clients get updated with the repodata.

Createrepo v 0.9.5 is required.

—update option is supported from v 0.9.5

it can be updated on AXS3, which has 0.4.3. without ‘update option’, creating repodata takes too long time. So it must be updated.

• v 0.9.7 seems to support delta rpm and requires yum v3.2.22 (higher than one in AXS3).

Suggested command to create repository

# createrepo –c /tmp/createrepo.cache/ARCH --update –database –g COMPFILE.xml /var/www/html/auth/asianux/AXS3/ARCH

- you can put the repodata into another place by option “-o /PATH” - comsfile should be in the target directory.

How yum deals with issues we met with AXTU

1. Obsolete package handling

• when updating packages with obsolete tag, the obsoleted packages are removed. But they(obsoleted packages) will show up in available package list for installation. 2. Packages with multi-architectures.
• it works fine. 3. Blacklist. (AXTU, Yum?)
  • not the same but plugin “yum-versionlock” would do the same function. Or we can make one. 4. none-latest package detection
• yum support, AXTU does not support. Ex) A 1.2 requires B 1.2 but the newest version is B1.3. AXTU can not install A 1.2 but yum can. 5. kernel update (not install)
• Kernel-header and kernel-doc are updated and only the latest versions remain.
• for other kernels packages, latest three packages are kept.
  • when old kernel is removed, dependent packages like kmod are remove together. 6. Incompatible package handling?
    • yum does not have it.. (as far as I know

When a package is added/removed from a repository, you can update the repodata so that clients get updated with the repodata.

• There are some useful tools you can use to manage yum repositories.

repomanage -k2 --old /some/dir | xargs rm –f  : to delete old files from repository
reposync : to sync between two repo or to clone a repository.
verifytree : to verify repositories and repodata
