¿Cómo migro una base de datos de Postgres a AWS RDS?

How do I migrate a Postgres database to AWS RDS?

This lesson has five steps.

1. Create a PostgreSQL database instance in Amazon RDS.
2. Create a replication instance in AWS Database Migration Service (AWS DMS)
3. Create endpoints in AWS DMS.
4. Create a replication task in AWS DMS.
5. Complete the migration and clean up resources.

Implementation

1. Enter the RDS Console. When you click here, the AWS management console will open in a new browser window, so you can keep this step-by-step guide open.
2. Create a PostgreSQL DB Instance.
3. Download a SQL Client.
4. Delete the DB Instance.

Migrate Your Application Database to Amazon RDS

1. Introduction.
2. Step 1: Create a new database on Amazon RDS.
3. Step 2: Enable security group access.
4. Step 3: Disable write access to the application.
5. Step 4: Export the application database from your Bitnami stack.
6. Step 5: Import the application database to Amazon RDS.

AWS supports PostgreSQL through a fully managed database service with Amazon Relational Database Service (RDS). Amazon Aurora with PostgreSQL compatibility is also built using PostgreSQL.

The following command in the psql utility cerates the dump file from the database named mydbname. Next, we create the target DB instance and restore the data into it using the pg_restore command. Use psql to create the database on the DB instance and load the data.

To import from Amazon S3 into RDS for PostgreSQL, your database must be running PostgreSQL version 10.7 or later. For more information on storing data with Amazon S3, see Create a Bucket in the Amazon Simple Storage Service Getting Started Guide.

Step 1: Create a file using pg_dump that contains the data to load The pg_dump utility uses the COPY command to create a schema and data dump of a PostgreSQL database. The dump script generated by pg_dump loads data into a database with the same name and recreates the tables, indexes, and foreign keys.

Step 1: Create a security group on AWS that has your computer’s IP address white listed. Step 2: Add that security group to the database instance you want to connect to. Step 3: Run pg_dump. Make sure to specify your user name (thanks @LHWizard) with the -U command.

To connect to a PostgreSQL DB instance using pgAdmin Open the RDS console and then choose Databases to display a list of your DB instances. Choose the PostgreSQL DB instance name to display its details. On the Connectivity & security tab, copy the endpoint. Also, note the port number.

When importing data into a MariaDB DB instance, you can use MariaDB tools such as mysqldump, mysql, and standard replication to import data to Amazon RDS. Importing Data into PostgreSQL on Amazon RDS – You can use PostgreSQL tools such as pg_dump, psql, and the copy command to import data to Amazon RDS.

RDS is a Database as a Service (DBaaS) that automatically configures and maintains your databases in the AWS cloud. The user has limited power over specific configurations in comparison to running MySQL directly on Elastic Compute Cloud (EC2). There are some tradeoffs when using RDS.

After the connection is configured, you can connect to your private RDS DB instance using an SSH tunnel.

This lesson has five steps.

1. Create a SQL Server database instance in Amazon RDS.
2. Create a replication instance in AWS Database Migration Service (AWS DMS)
3. Create source and target endpoints for your database migration.
4. Create a replication task in AWS DMS.
5. Complete the migration and clean up resources.

In this post, we will explore one approach to Migrate PostgreSQL DB on EC2 instance to RDS instance using AWS Data Migration services. Amazon Relational Database Service (Amazon RDS) is quite popular because of its easy setup, operation, and auto-scalability.

The pattern includes two migration options: using AWS Data Migration Service (AWS DMS) or using native PostgreSQL tools such as pg_dump, pg_restore, and psql, or third-party tools. PostgreSQL versions 9.3.12–12.

If you’re using AWS DMS as your migration tool, see also Using a PostgreSQL Database as a Source for AWS DMS for supported versions. An Amazon RDS for PostgreSQL database (same PostgreSQL version as the source database) AWS DMS – AWS Data Migration Service (AWS DMS) supports several different source and target databases.

If you have data in a PostgreSQL server on an Amazon EC2 instance and want to move it to a PostgreSQL DB instance, you can use the following process. The following list shows the steps to take.

Importing a PostgreSQL database from an Amazon EC2 instance

1. Create a file using pg_dump that contains the data to be loaded.
2. Create the target DB instance.
3. Use psql to create the database on the DB instance and load the data.
4. Create a DB snapshot of the DB instance.

Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/ .

1. In the navigation pane, choose Databases, and then choose the DB instance that you want to modify.
2. Choose Modify.
3. Change any of the settings that you want.

Migrating a snapshot of an RDS for PostgreSQL DB instance to an Aurora PostgreSQL DB cluster

1. Choose Snapshots.
2. On the Snapshots page, choose the RDS for PostgreSQL snapshot that you want to migrate into an Aurora PostgreSQL DB cluster.
3. Choose Actions then choose Migrate snapshot.

Export MySQL data from AWS RDS

1. Step 1: Establish a connection.
2. Step 2: Open Data Export wizard.
3. Step 3: Select file format.
4. Step 4: Select a source table.
5. Step 5: Set output options for the data to be exported.
6. Step 6: Set table grid options for the data to be exported.

The instance upgrade on the slave usually takes around 10 to 20 minutes, but there is no downtime in this setup.

If you don’t specify a preferred backup window when you create the DB instance, Amazon RDS assigns a default 30-minute backup window. This window is selected at random from an 8-hour block of time for each AWS Region.

The article will describe how to migrate from Oracle to PostgreSQL on the AWS RDS. Since it is heterogeneous migration of data engine. It involves the conversion of schemas as well. The two parts of a database migration are the schema conversion and data replication.

Download the JDBC driver for your target database (PostgreSQL) AWS SCT is a tool that can converts schema from one database engine to another database engine. AWS SCT automatically converts schema from source to target database and generate an assessment report.

If you are migrating to a different database engine than your source database, you can use the AWS Schema Conversion Tool (AWS SCT). You use AWS SCT to migrate schema objects that are not migrated by AWS DMS. For more information about AWS DMS, see What is AWS Database Migration Service?

When you migrate the DB snapshot by using the console, the console takes the actions necessary to create both the DB cluster and the primary instance. You can also choose for your new Aurora PostgreSQL DB cluster to be encrypted at rest by using an AWS Key Management Service (AWS KMS) encryption key.
