运行时

yum install mysql

默认情况下，

命令会安装mariadb而不是mysql.因此，请尝试以下命令

command by default it installs mariadb not mysql. so try this following command

yum list installed | grep mariadb

如果缺少mariadb服务器，请尝试以下命令

if mariadb-server is missing try this following command

yum install mariadb-server

它将安装服务器软件包，然后启动服务

it installs the server package then start the service

systemctl start mariadb

或

service mariadb start

我的问题已通过这种方式解决. 谢谢

My issue is solved in this way. Thanks
