我正在尝试更新 yum 但没有成功。我已经尝试了所有现有的解决方案,但无法修复它这是我得到的错误
[root@localhost ]# yum update 加载的插件:fastestmirror、langpacks 从缓存的主机文件加载镜像速度 无法检索镜像列表http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock错误为 14:curl#7 - “无法连接到 2001:1b48:203::4:10:网络无法访问”
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
起初我这样做了,但我得到了同样的错误
[root@localhost ]# ONBOOT=no
[root@localhost ]# dhclient
[root@localhost ]# yum update
然后我去了/etc/yum.repos.d/
vi CentOS-Base.repo
然后我删除了baseurl之前的#并通过:x保存并输入
现在我收到以下错误
[root@localhost yum.repos.d]# yum update
Loaded plugins: fastestmirror, langpacks

One of the configured repositories failed (CentOS-7 - Base),
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

distribution release than is supported by the repository (and the

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

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

我也使用了以下命令,但错误是相同的
yum clean all && yum clean metadata && yum clean dbcache && yum makecache && yum update -y
为了检查兴趣,我做了以下操作
[
root@localhost ~]# cat /etc/resolv.conf
; generated by /usr/sbin/dhclient-script
search dhcp.swmed.org
nameserver 199.242.236.1
nameserver 199.242.237.1
然后我 ping 第一个,收到以下消息
[root@localhost ~]# ping 199.242.236.1

/etc?yum.repos.d/CentOS-Base.repo如下

在 /etc/yum.conf 中设置代理信息,如下所示:
proxy=http://xxx.xxx.xxx.xxx:1087
proxy_username=

答案2
我在 CentOS 7.5 上也面临同样的问题,在完成所有调试后,我们发现硬件防火墙正在阻止 Yum URL。
在防火墙中允许网址后,我的问题已解决。
