Replication Setup Guide

This guide provides a comprehensive overview of setting up replication in our system. Replication is a critical feature that ensures data consistency and high availability across multiple servers.

Prerequisites

Before setting up replication, make sure you have the following prerequisites:

A running instance of our core application.
Access to the server where you want to set up replication.
Sufficient storage space on the server for the replicated data.

Step-by-Step Guide

1. Configure Replication Settings

First, you need to configure the replication settings in the application's configuration file. Here's an example of the replication settings:

replication:
  enabled: true
  master:
    host: master.example.com
    port: 5432
  slave:
    host: slave.example.com
    port: 5432

2. Create a Database User

Create a dedicated database user for replication. This user will be used to connect to the master server and replicate data.

CREATE USER replication_user WITH PASSWORD 'password';

3. Grant Permissions

Grant the necessary permissions to the replication user on the master database.

GRANT SELECT, REPLICATION ON ALL TABLES IN SCHEMA public TO replication_user;

4. Start Replication

Now, start the replication process by running the following command:

./start-replication.sh

5. Monitor Replication

Monitor the replication process to ensure that data is being replicated correctly. You can use the following command to check the replication status:

./check-replication.sh

Troubleshooting

If you encounter any issues during the replication setup, refer to the following troubleshooting tips:

Check the server logs for any errors or warnings.
Ensure that the network connection between the master and slave servers is stable.
Verify that the replication user has the necessary permissions.
