CentOS之——yum安裝軟體報錯（以CentOS 6.8安裝percona為例）

問題

具體報錯資訊如下：

repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.           

例如，在CentOS 6.8上安裝 percona

yum install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm
yum list | grep percona
yum install percona-toolkit           

最後一步報錯，報錯資訊如下所示：

warning: rpmts_HdrFromFdno: Header V4 RSA/SHA256 Signature, key ID 8507efa5: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Percona


The GPG keys listed for the "Percona-Release YUM repository - x86_64" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.           

解決方案

安裝現有的 gpg 公鑰，在 /etc/pki/rpm-gpg/ 下，可以執行如下指令直接把所有的都安裝上

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

yum -y install * --nogpgcheck           

yum install percona-toolkit --nogpgcheck
