Question

我想将我的 Rails EB Linux 从 1.11.8 更新到 2.12.2，所以我克隆了环境并提交给它，但我收到了这个错误：

PG::ConnectionBad (could not connect to server: Connection timed out
    Is the server running on host "example.ccexample.us-east-1.rds.amazonaws.com" (111.11.21.22) and accepting
    TCP/IP connections on port 5432?

另一个错误——可能是同样的问题？：

/opt/elastticbeanstalk/hooks/appdeploy/pre/12_db_migration.sh failed.

我的环境变量都是正确的，所以数据库不应该只是简单地连接吗？

这是错误日志：

我还用新的环境名称更新了 config.yml：

任何帮助将不胜感激

基于评论。

该问题是由 RDS 中错误的安全组 (SG) 入站规则引起的。 EB 克隆操作创建了新的 SG，这在 RDS 的 SG 中没有体现。

解决方案是更新 RDS 的 SG 并添加与克隆的 EB 环境关联的 SG。
