centos系统中yum出现“Could not retrieve mirrorlist ”的处理方法

04-23   来源:

  问题通常是在使用yum时候出现如下类似的错误内容?

 
Loaded plugins: fastestmirror, langpacks
 
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
 
12: Timeout on http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock: (28, "Resolving timed out after 30383 milliseconds")
 
 
 
 
 
 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
 
 
 
     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=.skip_if_unavailable=true
 
 
 
Cannot find a valid baseurl for repo: base/7/x86_64
 
 
 
这种情况通常是,是因为没有配置DNS服务器。
 
解决方法:用VI编辑resolv.conf文件
 
命令
 
vi /etc/resolv.conf
 
添加:
 
nameserver 114.114.114.114    国内的
 
wq
 
保存退出即可
