这里处理过程中，

1、执行yum install mysql-community-server -y遇到一个问题：
Error: Unable to find a match: mysql-community-server

2、Error: Transaction test error:
file /etc/my.cnf from install of mysql-community-server-5.7.38-1.el7.x86_64 conflicts with file from package mariadb-connector-c-config-3.1.11-2.tl3.noarch

直接干掉冲突的包
yum remove mariadb-connector-c-config-3.1.11-2.tl3.noarch

这里还不需要mariadb
