In this video, we provide a comprehensive, step-by-step guide on setting up PostgreSQL Streaming Replication on an Ubuntu-based system. Whether you're looking to set up a high-availability PostgreSQL setup or simply replicate data across different nodes, this tutorial covers everything you need to know.
What you'll learn in this video:
PostgreSQL Installation on Base Machine
We start by installing PostgreSQL on your Ubuntu server to lay the foundation for replication.
Configuration
Learn how to modify the postgresql.conf and pg_hba.conf files to configure:
Listen addresses for enabling remote connections.
Basic Authentication using MD5 for secure access.
Streaming Replication Setup
Configure critical replication settings in postgresql.conf:
wal_level (to ensure WAL archiving is active).
max_wal_senders (for handling replication connections).
hot_standby (to enable read queries on the replica).
Replication Users and Permissions
Set up the necessary replication users with proper permissions for secure communication between the primary and replica nodes.
Initializing Replica Nodes
Use pg_basebackup to initialize the replica from the primary server, ensuring that both servers have synchronized data.
Testing Failover
Finally, we demonstrate how to test failover by promoting the replica to the master and ensuring that the replication process works as expected.
This tutorial will help you ensure that your PostgreSQL setup is highly available, fault-tolerant, and properly configured for streaming replication.
