YUM 命令在 REDHAT 中失败，出现 [Errno 14] curl#60 - “SSL 证书：无法获取本地颁发者证书”

[Errno 14] curl#60 - "SSL certificate problem: unable to get local issuer certificate"当我使用 yum 命令安装或更新任何包时出现错误。

前任：

yum install curl

然后它给出像这样的输出

[root@dtetestmaster svradmin]# yum install curl
Loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-manager

Trying other mirror.
It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
You can try to solve this issue by using the instructions on 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 (Docker CE Stable - x86_64),
 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=docker-ce-stable ...

     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 docker-ce-stable
        or
            subscription-manager repos --disable=docker-ce-stable

     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=docker-ce-stable.skip_if_unavailable=true

failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.

请帮助解决此错误，谢谢！

答案1

这是直接从 Centos wiki 中列出的错误消息

  1. 验证系统是否可以在互联网上看到内容。

    ping google.com

  2. 此问题也可能由于本地计算机缓存损坏而发生，请尝试清除系统上的缓存：

    yum clean all

    rm -rf /var/cache/yum/*

  3. 如果您有代理服务器，请验证它在 /etc/yum.conf 中是否配置正确。以下是示例（您的名称、密码和端口号显然会有所不同）。

    代理 = http://mystuff.mydomain.com:1234
    代理用户名 = 代理用户
    代理密码 = 代理密码

  4. 暂时注释掉 .repo 文件中的 mirror= 行，然后：

    yum clean all; yum makecache

答案2

docker repo/configuration 出了点问题。如果你仔细阅读错误消息，你就会看到解决方案：

yum --disablerepo=docker-ce-stable install curl

更新：docker repo 看起来没问题。因此这是代理或 ca-certs 的本地安装问题。
