Question

我一直在CentOS 07上设置MariaDB10。我很难弄清楚该怎么做才能与MariaDB数据库建立远程连接。我确实在/etc/my.cnf.d中添加了“ bind-address = 0.0.0.0”，MariaDB在添加后确实列出了端口3306。经历了许多不同的指南，但无法弄清我所缺少的内容。我唯一要注意的是，没有列出TCP4（仅列出TCP6）。谢谢您的帮助。

    [xxx]# sudo netstat -anp | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      32561/mysqld
