获取 GPG 密钥失败：[Errno 14] curl#37 - "Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7"

这个就是安装的时候会检查key这个可以再repo文件中关闭即可

# vim /etc/yum.repos.d/epel.repo

[epel]

name=Extra Packages for Enterprise Linux 7 - $basearch

#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch

metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority

enabled=1

pgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

 

解决方法：

把gpgcheck=1  改为gpgcheck=0 即可，意思是在安装的时候不进行源的检查
