您如何迁移 Mirthconnect 以使用 MySQL/MariaDB

Question

当尝试连接 mirthconnect 以使用 mariaDB 而不是 Derby 嵌入式数据库时，mirth connect 在创建数据库时失败。

使用：

Ubuntu 18.04 LTS
MariaDB 10.1.29-MariaDB-6
欢乐连线 3.6.0
Java openjdk 10.0.1

设置步骤：

安装 Maria DB
安装 Mirth 连接。
创建用于 Mirth 的数据库
在 Maria DB 中创建 mirth 用户
配置 mirth 连接以连接到 Maria DB
开始欢乐服务

启动 mirthconnect 服务时抛出以下异常。

有问题的错误

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes

似乎与密钥长度有关 - 数据库默认字符集是 utf16 而不是 utf8，因此由于字符大小（以字节为单位），其中一个表的密钥大小实际上大于 767 字节。

为 mirth 创建数据库时 - 确保字符集设置为 UTF8

create database mirthconnect character set utf8 collate utf8_general_ci;
