rpm数字证书安装

当本地yum源配置文件中gpgcheck=1，使用yum install安装软件前需要安装光盘中自带的rpm数字证书。

1.配置本地yum源

本地yum源repo配置文件如下：

[root@monitor rpm-gpg]# cat /etc/yum.repos.d/local.repo[local-repo]name='local repo'enable=1baseurl=file:///mnt/isogpgcheck=1

2.未安装数字证书时yum install软件报错

[root@monitor yum.repos.d]# yum install lftpwarning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEYPublic key for lftp-4.0.9-1.el6.x86_64.rpm is not installed

3.安装rpm数字证书

rpm的数字证书位于centos安装光盘目录中，通常以RPM-GPG-KEY-开头。

[root@monitor iso]# ls RPM-GPG-KEY-CentOS-*RPM-GPG-KEY-CentOS-6  RPM-GPG-KEY-CentOS-Debug-6  RPM-GPG-KEY-CentOS-Security-6  RPM-GPG-KEY-CentOS-Testing-6

安装数字证书

[root@monitor iso]# rpm --import RPM-GPG-KEY-CentOS-*

查找已经安装的数字证书

[root@monitor iso]# find /etc -name '*RPM-GPG*'/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Security-6/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Testing-6/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
