  file /etc/my.cnf from install of mysql-community-server-5.7.24-1.el7.x86_64 conflicts with file from package mariadb-connector-c-config-3.1.11-2.el8_3.noarch

查阅了网上资料，大多是修改文件 /etc/yum.repos.d/mysql-community.repo 目录下的文件，但是我这个问题还是没有解决。
我又看了一眼报错信息，提示说和后面这个包（mariadb-connector-c-config-3.1.11-2.el8_3.noarch）冲突了，我查了一下 yum list installed，确实安装了这个软件包，那就卸载了试试。输入命令yum remove [pakeageName]，再重新安装server包。成功安装server软件包
