centos安装mysql报错：mysql-community-client-plugins-8.0、o Presto metadata available for mysql80-community

执行sudo yum -y install mysql-community-server命令

刚开始报错mysql-community-client-plugins-8.0.40-1.el7.x86_64.rpm 的公钥尚未安装 失败的软件包是：mysql-community-client-plugins-8.0.40-1.el7.x86_64 GPG 密钥配置为：file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

再执行

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

手动导入秘钥 

然后报错
