今天遇到一个在CentOS7下用rpm-gpg-key-epel-6的文件安装
yum install gridengine-6.2u5-10.el6.4.x86_64 gridengine-devel-6.2u5-10.el6.4.x86_64 gridengine-execd-6.2u5-10.el6.4.x86_64 -y
结果爆出如下错误：
安装大小：55 M
Downloading packages:
warning: /var/cache/yum/x86_64/7/epel/packages/fedora-usermgmt-0.10-1200.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY
从 file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 检索密钥
获取 GPG 密钥失败：[Errno 14] curl#37 - "Couldn‘t open file /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6"
[root@mailan yum.repos.d]# rpmkeys --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-20-primary
错误：/etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-20-primary: import read failed(2).
后来搜索半天，找出解决方法,执行如下操作即可:
将/etc/pki/rpm-gpg目录下的rpm-gpg-key-epel-6导入即可
[root@mailan rpm-gpg]# pwd
/etc/pki/rpm-gpg
[root@mailan rpm-gpg]# ls -l
