Terraform AWS Aurora模块部署错误排查与修复

错误根源分析

你遇到的三个错误全部来自代码中多余的未配置模块module "rds-aurora"：

cluster_identifier相关错误：该模块未传入name参数，var.name为空字符串，不符合AWS对集群标识符的命名规则（必须以字母开头，仅含小写字母、数字和连字符）
engine缺失错误：该模块未传入engine参数，而这是模块的必填项，导致资源创建失败

你配置的module "aurora"参数是正确的，但因为同时声明了一个无配置的模块，Terraform会尝试创建两个集群，其中无配置的那个触发了所有错误。

修复步骤

删除未配置的module "rds-aurora"块：这个模块没有传入任何必填参数，属于无效的资源声明
验证保留的module "aurora"参数：你的name = "webcam-service-aurora-db"符合AWS命名规则，engine = "aurora-mysql"也是合法值

修复后的完整代码

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.78.0"
    }
  }
}

provider "aws" {
  region = "eu-central-1"
}

module "aurora" {
  source  = "terraform-aws-modules/rds-aurora/aws"
  version = "9.10.0" # 建议给模块指定版本，避免自动更新导致兼容性问题

  name = "webcam-service-aurora-db"
  engine = "aurora-mysql"
  engine_version = "8.0"
  instance_class = "db.t4g.medium"
  vpc_id = "vpc-073c3bc9571c4bffe"

  master_username = "root"

  instances = {
    one = {}
  }

  storage_encrypted = false
  apply_immediately = true
  skip_final_snapshot = true
  monitoring_interval = 10
  enabled_cloudwatch_logs_exports = ["error", "slowquery"]

  tags = {
    Environment = "experiment"
    Terraform = "true"
  }
}
