現象：使用yum命令安裝軟件，報如下錯誤：centos

failure: repodata/repomd.xml from epel: [Errno 256] No more mirrors to try.
http://mirrors.cloud.aliyuncs.com/epel/6/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.cloud.aliyuncs.com; Name or service not known"緩存

緣由：yum 源 mirrors.cloud.aliyuncs.com不存在。curl

解決辦法：this

一、首先進入 /etc/yum.repos.d 目錄，備份CentOS-Base.repo源，url

#cp CentOS-Base.repo CentOS-Base.repo.bak spa

二、修改 CentOS-Base.repo 文件3d

#vi CentOS-Base.repoxml

將http://mirrors.cloud.aliyuncs.com 批量替換爲 http://mirrors.aliyun.comblog

三、備份epel.repo源，修改epel.repo文件it

#cp epel.repo epel.repo.bak

#vi epel.repo

http://mirrors.cloud.aliyuncs.com 批量替換爲 http://mirrors.aliyun.com

四、清理yum緩存和從新生成緩存，

#yum clean all

#yum makecache

以後繼續yum就正常了。

如yum安裝時，還報如下錯誤：

warning: /var/cache/yum/x86_64/7/base/packages/httpd-tools-2.4.6-88.el7.centos.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
Retrieving key from http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-6

The GPG keys listed for the "CentOS-7 - Base" repository are already installed but they are not correct for this package.

Check that the correct key URLs are configured for this repository.

解決辦法：

執行：#rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
