yum 仓库配置失败

2019-03-04 0 By admin

在Docker 服务中配置yum仓库时,导致yum管理命令完全不能正常使用。虽然最后也没有解决问题,但本文记录一下过程,并提供一个可能的解决方法。



One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

1. Contact the upstream for the repository and get them to fix the problem.

2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).

3. Run the command with the repository temporarily disabled
yum –disablerepo= …

4. Disable the repository permanently, so yum won’t use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use –enablerepo for temporary usage:

yum-config-manager –disable
subscription-manager repos –disable=

5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice

yum-config-manager –save –setopt=.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/$releasever/x86_64


通过使用yum-config-manager查看yum repo的参数,发现$releasever值都没有转化为相应的数值7。
检查相应的缓存目录:cachedir = /var/cache/yum/x86_64/$releasever/updates
