mysql-community-common-5.7.42-

mysql-community-common-5.7.42-1.el7.x86_64.rpm报错的原因可能是由于缺少相应的GPG密钥。在安装MySQL时，运行命令：yum -y install mysql-community-server，系统会自动下载并验证软件包的完整性和安全性。如果下载的软件包没有正确的GPG密钥进行验证，就会出现报错。解决这个问题的方法是重新下载MySQL并重新安装。可以运行命令：yum -y install mysql-community-server来重新下载和安装MySQL。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
