原因，顺序错误
使用 rpm 安装 MySQL，需要严格按照如下的执行顺序进行安装，如果顺序不对，会提示某某包需要被依赖。
rpm -ivh mysql-community-common-8.0.34-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.0.34-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.34-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.34-1.el7.x86_64.rpm
rpm -ivh mysql-community-icu-data-files-8.0.34-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.34-1.el7.x86_64.rpm
