如何将 liquibase 连接到 AWS RDS Aurora MySQL 数据库
How to connect liquibase to AWS RDS Aurora MySQL database
我正在尝试设置 liquibase 以基于 AWS RDS Aurora MySql 为项目同步我的开发和生产数据库。不幸的是，我无法将 liquibase 连接到我的 AWS Aurora MySQL 数据库。
我做了什么？
- 已安装 liquibase
- 已阅读文章 https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.Connecting.html，其中解释了如何通过 JDBC 连接到 AWS RDS Aurora MySQL 数据库集群。
- 我下载了 Maria DB JDBC 连接器
- 我使用附录 1 中所述的数据配置了 liquibase.properties 文件
- 我运行命令`liquibase --driver=org.mariadb.jdbc.Driver --classpath=
mariadb-java-client-2.7.1.jar generateChangeLog``
- liquibase 按预期启动并尝试连接到数据库 prod 集群，但随后挂起一段时间后终止，并出现异常“通信 link 主节点失败。未找到主节点的活动连接。” - 请参阅附录 2 中的堆栈跟踪
我的问题：
如何配置 liquibase 才能获得 运行 AWS RDS Aurora MySQL 数据库集群？
谢谢和最诚挚的问候

我自己仍在调查，这是 AWS 的一位高级技术客户经理提供的 good article 以熟悉如何将事物连接在一起。
总而言之，您必须在 AWS 生态系统上工作，在 EC2 上部署 Liquibase 和 CI/CD 软件（如 Jenkins），并将您的 SQL 存储库提交到 AWS codecommit。请注意，这通常适用于 Aurora，但在无服务器的情况下，您可能会遇到连接问题，因此我建议您通过 Data API 通过 HTTP 连接它，但这是一个正在进行的过程，我仍在调查中。

我自己仍在调查，这是 AWS 的一位高级技术客户经理提供的 good article 以熟悉如何将事物连接在一起。
总而言之，您必须在 AWS 生态系统上工作，在 EC2 上部署 Liquibase 和 CI/CD 软件（如 Jenkins），并将您的 SQL 存储库提交到 AWS codecommit。请注意，这通常适用于 Aurora，但在无服务器的情况下，您可能会遇到连接问题，因此我建议您通过 Data API 通过 HTTP 连接它，但这是一个正在进行的过程，我仍在调查中。
