centos 7 yum 問題.

HI 各位師兄,

剛裝CENTOS7 學LINUX.   但發覺YUM 有問題,   e.g yum install httpd , 會有error 如下.
以前版本唔覺有依個問題出現,   試過改proxy 8080 to 1234,  試過yum clean all 都唔得.
google 唔覺有solution,  請問點fix 依個問題呢?   thx all.

yum install httpd

Loaded plugins: fastestmirror, langpacks
Could not retrieve mirrorlist http://mirrorlist.centos.org/?re ... =os&infra=stock error was
14: curl#5 - "Could not resolve proxy: proxy.com; Unknown error"

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. Disable the repository, 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 <repoid>

     4. 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=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64
