在我的 vps 中，我想从 MySQL 切换到 MariaDB（使用 Monty 的 Debian Squeeze 存储库）。将 my.cnf 从 MySQL 复制到 MariaDB，我看到新的配置文件（MariaDB 包中的那个）没有提到任何插件命令，例如 MySQL 中的旧配置文件，我在其中加载了 InnoDB 插件。现在，我了解到 XtraDB 已经成为 MariaDB 中默认的 ACID 存储引擎，取代了 InnoDB。由于我发现 MariaDB 站点的文档在这方面缺乏，我需要在新的 my.cnf 中添加一些额外的东西来激活 XtraDB 还是默认激活？show plugins返回这个：

我从上面的输出中理解了什么？那个 InnoDB=XtraDB？
