[Errno 14] curl#6 - “Could not resolve host 无法使用ifconfig

博客讲述在阅读《how linux works》时,遇到无法执行ifconfig命令且yum安装连接不到镜像网站的问题。解决方案是进入/etc/sysconfig/network-scripts目录,修改ifcfg-eno16777736文件,将最后一行改为yes,重启网络后再安装,测试可正常运行。

[root@localhost ~]# sudo yum install -y ca-certificates --disablerepo=* --enablerepo=base 已加载插件:fastestmirror, langpacks Loading mirror speeds from cached hostfile http://mirrors.aliyun.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden 正在尝试其它镜像。 To address this issue please refer to the below wiki article https://wiki.centos.org/yum-errors If above article doesn't help to resolve this issue please use https://bugs.centos.org/. One of the configured repositories failed (CentOS-7 - Base - Aliyun), 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=base ... 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 base or subscription-manager repos --disable=base 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=base.skip_if_unavailable=true failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try. http://mirrors.aliyun.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden
