    #  This is the default, if you make this bigger yum won't see if the metadata

    # is newer on the remote and so you'll "gain" the bandwidth of not having to

    # download the new metadata and "pay" for it by yum not having correct

    # information.

    #  It is esp. important, to have correct metadata, for distributions like

    # Fedora which don't keep old packages around. If you don't like this checking

    # interupting your command line usage, it's much better to have something

    # manually check the metadata once an hour (yum-updatesd will do this).

    # metadata_expire=90m

    繼續(xù)運(yùn)行，出現(xiàn)如下錯(cuò)誤

    [root@localhost ~]# yum install lrzsz

    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; 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. Run the command with the repository temporarily disabled

    yum --disablerepo=<repoid> ...

    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 <repoid>

    or

    subscription-manager repos --disable=<repoid>

    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

    compromise:

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

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

    ==============================================

    原因：沒有配置resolv.conf

    解決方法:

    到/etc目錄下配置resolv.conf加入nameserver IP,如：

    1

    2

    3

    4

    [root@localhost ~]# vi /etc/resolv.conf

    nameserver 8.8.8.8

    nameserver 8.8.4.4

    search localdomain

    保存再次運(yùn)行命令就可以。
