[Warning] World-writable config file ‘/etc/mysql/mysql.conf.d/mysqld.cnf’ is ignored.

mysql版本8.0.18，添加mysql.cnf一直无效，使用命令行连接mysql.cnf是报警告 [Warning] World-writable config file '/etc/mysql/mysql.conf.d/mysqld.cnf' is ignored.

原因: 需要将mysql.conf.d文件通过chmod进行权限降级。

chmod 644 /etc/mysql/conf.d/mysql.cnf
