  • CentOS执行yum报错

    已加载插件:fastestmirror
    Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
    14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"


    One of the configured repositories failed (未知),
    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
    compromise:

    yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

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

    -------------------------------------------------------------------------------------------------------------------------

    原因:没有配置resolv.conf
    解决方法:
    到/etc目录下配置resolv.conf加入nameserver IP,如:
    nameserver 8.8.8.8
    nameserver 8.8.4.4
    search localdomain
     
     
    这里要注意,一定要保证search localdomain在最下面,保证上述顺序。
    保存再次运行上面命令就可以。
