今天使用centos8.5安装MySQL出现如上错误

显示

参数不匹配：mysql community server

错误：无法找到匹配项：mysql community server

解决办法，第一步查看是否安装MySQL源

检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*.community.*"

如看到没有

请.安装mysql源在进行安装

yum localinstall mysql57-community-release-el7-8.noarch.rpm

再进行安装MySQL

yum install mysql-community-server

若看到已安装MySQL源，
