Connect Magento to PostgreSQL: Simplified 101

Magento is an eCommerce platform built on open source technology that provides online merchants with a flexible shopping cart system, as well as control over the look, content, and functionality of their online store. Magento offers powerful marketing, search engine optimization, and catalog-management tools.

PostgreSQL is a robust, open-source object-relational database system that has a strong reputation for reliability, feature robustness, and performance. It has been actively developed for over 30 years.

This article explains how to connect Magento to PostgreSQL. It also gives an overview of Magento and PostgreSQL.

What is Magento?

Magento is a PHP-based open-source e-commerce platform. It also makes use of other PHP frameworks like Laminas and Symfony. The Open Software License (OSL) v3.0 governs the distribution of Magento source code. Adobe Inc bought Magento for $1.68 billion in May 2018.

Magento allows users to customize the appearance, functionality, and content of their online store without sacrificing the shopping experience while providing several useful tools and features to its users. Marketing, search engine optimization, and catalog-management tools are all included.

Overall, the platform is adaptable to any store size. Magento offers both a free Magento Open Source and a feature-rich Magento Commerce platform, so it can grow and evolve with your business, whether you have a few customers or a million. As a company grows, it may be necessary to switch platforms.

However, Magento makes it simple to stay in one place and grow. Customers can also choose from a variety of plug-ins and themes to suit whatever they want to do with their website and how they want it to look. These can also improve customer relationships and enhance the customer experience.

The platform’s creators made it simple to use for regular people. This implies that you are not required to have any technical or developmental experience.

The system, on the other hand, is dependable. The system becomes more complex as you grow because it can handle millions of customers.

In most cases, businesses will need to hire outside assistance. However, this is only true when a company begins to integrate multiple systems into its website.

The first version of Magento was released in 2007. Magento was acquired by Adobe in May of this year, which was the most recent development.

What is PostgreSQL?

PostgreSQL is an open-source advanced model of the relational database system. PostgreSQL is a dependable database that has been developed by the open-source community for more than two decades.

Among the existing Open Source DBMS, only PostgreSQL offers enterprise-class performance and functions, as well as limitless growth opportunities. It is a major database used by both large organizations and startups to support their applications and products. It is generally utilized as a powerful back-end database that supports a wide range of dynamic websites and web applications.

Postgres provides querying and windowing capabilities. It supports relational and as well as non-relational querying. Because of its adaptability, it can be used as both a transactional database and a data warehouse for analytics.

 PostgreSQL assists developers in creating the most complex applications, running administrative tasks, and creating integral environments. Many web applications, as well as mobile and analytics apps, use PostgreSQL as their primary database.

PostgreSQL was designed to allow the addition of new capabilities and functionality. You can create your data types, index types, functional languages, and other features in PostgreSQL.If you don’t like something about the system, you can always create a custom plugin to make it better, such as adding a new optimizer.

Key Features of PostgreSQL

• Querying and Programming Language Support: PostgreSQL supports both SQL and JSON querying. The most prominent programming languages supported by PostgreSQL are Python, Java, C#, C/C+, Ruby, JavaScript, Perl, Go, and Tcl. 
• Table Inheritance: PostgreSQL supports a strong object-relational feature called inheritance. This enables a table to inherit part of its column properties from one or more other tables through inheritance, forming a parent-child connection. The child table inherits the same columns and constraints as its parent table (or tables), as well as its defined columns.
• Multi-version Concurrency Control (MVCC): Unlike most other database systems, which employ locks to regulate concurrency, Postgres uses a multi-version architecture model to maintain data consistency. This implies that each transaction in a database sees a snapshot of data from a previous transaction, regardless of the current state of the underlying data. This protects the transaction from viewing inconsistent data that could be caused by concurrent transaction updates on the same data rows, providing transaction isolation for each database session.
• Foreign Key Referential Integrity: PostgreSQL foreign key concept is based on the first table combination of columns with primary key values from the second table. It is also known as constraints or referential integrity constraints. It is specified that the values of the foreign key constraints column, which was corresponding with the actual values of the primary key column from another table.
• Asynchronous Replication: Asynchronous replication in  PostgreSQL offers a reliable and easy way to distribute data and make your setups more failsafe. In the event of server failure and disaster, Administrators can create read-only replicas of a primary server easily.

Method 2: Using Custom Code to Move Data from Magento to PostgreSQL

To manually connect Magento to PostgreSQL, you’ll need to do the following:

• Magento to PostgreSQL: Retrieve the Magento BI Public Key
• Magento to PostgreSQL: Allow Access to the Magento BI IP Address
• Magento to PostgreSQL: Create a Linux User for Magento BI
• Magento to PostgreSQL: Create a Postgres User for Magento BI
• Magento to PostgreSQL: Enter the Connection and User Info Into Magento BI

Magento to PostgreSQL: Retrieve the Magento BI Public Key

This is the first step to manually connecting Magento to PostgreSQL.The Magento BI Linux user is authorized using the public key. The user will then be created, and the key will be imported.

• Step 1: Click the Add a Data Source button under Manage Data > Connections.
• Step 2: Select PostgreSQL from the drop-down menu.
• Step 3: Toggle the Encrypted button to Yes once the PostgreSQL credentials page has opened. This will bring up the SSH configuration form.
• Step 4: This form’s public key can be found beneath it.

Magento to PostgreSQL: Allow access to the Magento BI IP Address

Your firewall must be configured to allow access from our IP address for the connection to work. It’s 54.88.76.97/32, but the PostgreSQL credentials page lists it as well.

Magento to PostgreSQL: Create a Linux User for Magento BI

It doesn’t matter if this is a primary or secondary machine, as long as it has real-time (or frequently updated) data. You can limit this user in any way you want as long as it has access to the PostgreSQL server.

• Step 1: Run the commands below as root on your Linux server to create the new user:

 adduser rjmetric -p<password>
        mkdir /home/rjmetric
        mkdir /home/rjmetric/.ssh

• Step 2: You must import the key into authorized keys to ensure the user has access to the database. In the authorized keys file, paste the entire key as follows: 

 touch /home/rjmetric/.ssh/authorized_keys
     "<PASTE KEY HERE>" >> /home/rjmetric/.ssh/authorized_keys

• Step 3: To complete the user’s creation, change the permissions on the /home/rjmetric directory to allow SSH access:

chown -R rjmetric:rjmetric /home/rjmetric
        chmod -R 700 /home/rjmetric/.ssh

Only certain users will have server access if the sshd config file associated with the server is not set to the default option, which will prevent a successful connection to Magento BI. In these cases, a command like AllowUsers must be used to grant the rjmetric user access to the server.

Magento to PostgreSQL: Create a Postgres User for Magento BI

Although your company may have its procedures, the simplest way to create this user is to run the following query while logged into Postgres as a user with the right to grant privileges. The user should also be the owner of the schema to which Magento BI has access.

 GRANT CONNECT ON DATABASE <database name> TO rjmetric WITH PASSWORD <secure password>;GRANT USAGE ON SCHEMA <schema name> TO rjmetric;GRANT SELECT ON ALL TABLES IN SCHEMA <schema name> TO rjmetric;ALTER DEFAULT PRIVILEGES IN SCHEMA <schema name> GRANT SELECT ON TABLES TO rjmetric;

** should be replaced with a secure password that is not the same as the SSH password. Also, make sure that ** and ** in your database are replaced with the appropriate names.

Repeat this procedure as needed if you want to connect multiple databases or schemas.

Magento to PostgreSQL: Enter the Connection and User Info Into Magento BI

Finally, we must enter the connection and user information into Magento BI. If you don’t see the PostgreSQL icon, go to Manage Data > Connections and click the Add a Data Source button. Make sure the Encrypted button is set to Yes.

Starting with the Database Connection section, fill in the following information on this page:

• Username: The username for RJMetrics Postgres (should be rjmetric)
• Password: The password for RJMetrics Postgres.
• Port: PostgreSQL port on your server (5432 by default)
• Host: 127.0.0.1

Under “SSH Connection,” make the following changes:

• Username: The IP address or hostname of the server we’ll SSH into. Remote Address: Our SSH username and password (should be rjmetric)
• SSH Port: Your server’s SSH port (22 by default)

To finish the setup, click the Save & Test button to connect Magento to PostgreSQL.
