  • CentOS7下报错:Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock32 error was 14: curl#6

    Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock32 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. 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

    造成这种报错的原因是没有联网。

    解决办法是

      在终端中输入以下命令,查看安装在本机的网卡:nmcli d

      cd /etc/sysconfig/network-scripts/本机网卡

          BOOTPROTO=dhcp
          ONBOOT=yes

       然后,通过键入以下命令重新启动网络服务:

        service network restart

      ping一下百度试试。。。

      

    闲静少言,不求达内。乐于技,喜刨根,不求甚解;每有会意,其乐无穷。
