你要下载的资源就是那个Url对应的资源请求失败了

hp640d4
hp640d4 或者说你的主机没联网
4 年多之前 回复

你可以自己去网上下载下来再安装

对应的源访问有问题 可能源没了也可能你网络访问不了

centos7 linux 执行yum (虚拟机下)

[root@sh04181125 network-scripts]# yum install docker Loaded plugins: fastestmirror 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 30982 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 <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 [root@sh04181125 network-scripts]# ping www.baidu.com ping: unknown host www.baidu.com 内网是通的

LINUX下yum命令出错,yum -y(centos)

![图片说明](https://img-ask.csdn.net/upload/201701/14/1484409420_11809.png) 今天根据教程安装ruby环境,然后遇到问题需要执行 yum - y(centos)命令,然后出现这样的情况,有人知道怎么解决吗,安装ruby好烦啊。。。
