希望有人可以帮助我，因为我不是 Linux 专业人士。
答案1
正如您所附的，它来自日志：
原因：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：“REG_CREATED_TIME”的默认值无效
根据这个，Ubuntu 或 Linux 没有问题。这是一个 Java 问题，日志是 Java 堆栈跟踪。
更新：
好的，我做了一些调查，并尝试安装一个用 Java 编写的企业服务总线 ESB 服务器。当您运行脚本时，它会尝试使用一些默认值初始化数据库。但是它无法完成，因为这个错误（见上文）。
我认为 MySQL 的不同版本导致了此错误或 JDBC 连接器版本差异。
你应该遵循文件或与开发人员取得联系。
答案2
这是 MySql 5.7 的一个已知问题。这里提到了一种解决方法[1]
解决方法：
设置 GLOBAL sql_mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION";
