Since “postgresql.x86_64” contains psql, install it. In this configuration, the EC2 instance is located on a private subnet, so we will access the repository via the VPC endpoint for S3.įirst, check the packages that can be installed. psql can be obtained from an Amazon Linux repository built on S3. To connect to a PostgreSQL instance, you need a dedicated client (psql). Create CloudFormation stacks and check resources in stacksįor information on how to create stacks and check each stack, please refer to the following pageįind out how to connect to a PostgreSQL instance. Use CloudFormation to build this environment and check its actual behavior. March 2022 latest version, and default port number. The main parameters for the two DB instances are as follows Cluster ID This is also a verification, so no special settings are made. Resources: DBInstance: Type: AWS::RDS::DBInstance Properties: AllocatedStorage: !Ref DBAllocatedStorage AvailabilityZone: !Sub "$" PubliclyAccessible: false Code language: YAML ( yaml ) Parameter 1 for RDS to be createdĬheck the parameters for the five DB instances other than Aurora. In this section, we will review the parameters for building each DB instance. The CloudFormation template is placed at the following URL The above configuration is built using CloudFormation. The following settings are common to all DB instances. No Internet or NAT gateway is deployed in this VPC, and the S3 bucket is accessed via the VPC endpoint for S3. On the other VPC, deploy each DB instance and an Amazon Linux 2 instance for connection verification. Deploy the latest Amazon Linux 2 instance, create a repository containing client packages for Oracle and Microsoft SQL Server connections, and upload them to an S3 bucket. In this article, we will check how to connect to the above 7 types of DB instances from Amazon Linux 2. I want to write 1 connection module, and use different drivers to connect to the different databases.How to connect to all RDS DB engines from Amazon Linux 2Īs of 2022, RDS offers the following seven DB engines I have used psycopg2 in the past to connect to Postgres, however my current company uses Netezza, Postgres, and MySQL. Odbcinst.ini file looks like this: ĭescription = PostgreSQL ODBC driver (ANSI version)ĭescription = PostgreSQL ODBC driver (Unicode version) Obdc.ini file looks like this: ĭescription = PostgreSQL connection to '' database I get the following error: pyodbc.Error: ('08001', ' connction string lacks some options (202) (SQLDriverConnect)') +-+īut when I try to connect with pyodbc: import pyodbcĬon = nnect("DRIVER= DATABASE= UID= PWD= SERVER=localhost PORT=5432 ") I can connect to the DB with isql: echo "select 1" | isql -v my-connector Trying to connect to Postgres using pyodbc. ![]()
