warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

安裝數據庫時，預檢發現軟件包compat-libstdc++-33沒裝

掛載了redhat 6.7 ISO

mount -o loop ./rhel-server-6.7-x86_64-dvd.iso /mnt

並配置了repo

[root@db1 yum.repos.d]# cat local.repo
[local]
name=rhel67
baseurl=file:///mnt
gpcheck=0

安裝報錯：

warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

解決方法：

rpm --import /etc/pki/rpm-gpg/RPM*

再去安裝，便可
