[英]AWS RDS for PostgreSQL Connection attempt timed out error
I created postgresql rds in aws with terraform. I'm checking from the aws console, everything seems normal.我用 terraform 在 aws 中创建了 postgresql rds。我正在从 aws 控制台检查,一切似乎都很正常。 But I'm trying to connect to database with DBeaver but I can't connect.
但是我正在尝试使用 DBeaver 连接到数据库,但我无法连接。 Likewise, I can't make the ssh connection for the ec2 I created, maybe there is a connection.
同样,我无法为我创建的 ec2 建立 ssh 连接,也许有连接。 The terraform codes I wrote:
我写的terraform代码:
# postgres-db/main.tf
resource "aws_db_instance" "default" {
allocated_storage = 20
storage_type = "gp2"
engine = var.engine
engine_version = var.engine-version
instance_class = var.instance-class
db_name = var.db-name
identifier = var.identifier
username = var.username
password = var.password
port = var.port
publicly_accessible = var.publicly-accessible
db_subnet_group_name = var.db-subnet-group-name
parameter_group_name = var.parameter-group-name
vpc_security_group_ids = var.vpc-security-group-ids
apply_immediately = var.apply-immediately
skip_final_snapshot = true
}
module "service-db" {
source = "./postgres-db"
apply-immediately = true
db-name = var.service-db-name
db-subnet-group-name = data.terraform_remote_state.server.outputs.db_subnet_group
identifier = "${var.app-name}-db"
password = var.service-db-password
publicly-accessible = true # TODO: True for now, but should be false
username = var.service-db-username
vpc-security-group-ids = [data.terraform_remote_state.server.outputs.security_group_allow_internal_postgres]
}
resource "aws_security_group" "allow_internal_postgres" {
name = "allow-internal-postgres"
description = "Allow internal Postgres traffic"
vpc_id = aws_vpc.vpc.id
ingress {
from_port = 5432
to_port = 5432
protocol = "tcp"
cidr_blocks = [aws_vpc.vpc.cidr_block, "0.0.0.0/0"] # TODO: Remove public IP
}
}
In the research I did, it was written things like edit the security rules or set it to public, it seems like that anyway.在我做的研究中,它写了一些东西,比如编辑安全规则或将其设置为公开,反正看起来是这样。
Security group inbound rules安全组入站规则
How can I solve this problem can you please help?我该如何解决这个问题,你能帮忙吗?
I solved my problem by setting the su.net group to public.我通过将 su.net 组设置为公开解决了我的问题。
module "service-db" {
source = "./postgres-db"
apply-immediately = true
db-name = var.service-db-name
db-subnet-group-name = data.terraform_remote_state.server.outputs.db_subnet_group_public
identifier = "${var.app-name}-db"
password = var.service-db-password
publicly-accessible = true # TODO: True for now, but should be false
username = var.service-db-username
vpc-security-group-ids = [data.terraform_remote_state.server.outputs.security_group_allow_internal_postgres]
}
resource "aws_db_subnet_group" "private" {
name = "${var.server_name}-db-subnet-group-private"
subnet_ids = aws_subnet.private.*.id
tags = {
Name = "${var.server_name} DB Subnet Group Private"
}
}
resource "aws_db_subnet_group" "public" {
name = "${var.server_name}-db-subnet-group-public"
subnet_ids = aws_subnet.public.*.id
tags = {
Name = "${var.server_name} DB Subnet Group Public"
}
}
