redis-config-server

Overview

redis-config-server is a custom high-availability management service designed to mimic the behavior of Redis Sentinel, with extended functionalities and enhanced stability. This server is built using Go and integrates with a Raft-based consensus algorithm to provide consistent and fault-tolerant monitoring of Redis master-slave setups.

redis-config-server can manage multiple Redis instances, handle failover scenarios, and respond to Redis Sentinel commands using the Redis protocol. It is a robust alternative for managing Redis clusters, offering better scalability and customization options.

Features

• High Availability Management: Monitors Redis master and slave nodes, providing automated failover in case of node failure.
• Raft Consensus Algorithm: Ensures consistent state across multiple redis-config-server instances, offering fault tolerance and reliability.
• Redis Protocol Support: Compatible with Redis Sentinel commands such as MONITOR, RESET, REMOVE, MASTERS, MASTER, and INFO.
• Custom Command Processing: Easily extendable to support additional Redis commands.
• Real-time Monitoring: Continuously monitors the health of Redis instances and takes action based on their status.

Installation

Prerequisites

• Go 1.16 or higher
• Redis 5.0 or higher
• go-redis/redis/v9 library for Go
• hashicorp/raft library for Go

Clone the Repository

git clone https://github.com/Praying/redis-config-server.git
cd redis-config-server

Build the Project

go build -o redis-config-server main.go

Usage

Starting the redis-config-server

To start the redis-config-server, run the following command:

./redis-config-server

Sentinel Commands

redis-config-server supports several Redis Sentinel commands:

1. SENTINEL MONITOR

Monitors a new master instance:

redis-cli -p 26379 SENTINEL MONITOR <master-name> <ip> <port> <quorum>

2. SENTINEL RESET

Resets monitoring for a specific master:

redis-cli -p 26379 SENTINEL RESET <master-name>

3. SENTINEL REMOVE

Removes a master from monitoring:

redis-cli -p 26379 SENTINEL REMOVE <master-name>

4. SENTINEL MASTERS

Lists all monitored master instances:

redis-cli -p 26379 SENTINEL MASTERS

5. SENTINEL MASTER <master-name>

Gets detailed information about a specific master instance:

redis-cli -p 26379 SENTINEL MASTER <master-name>

6. SENTINEL INFO

Provides general information about the redis-config-server instance:

redis-cli -p 26379 SENTINEL INFO

Configuration

The server configuration is typically done via a Sentinel configuration file (sentinel.conf). Ensure that your Redis instances and configurations are properly set up before starting the redis-config-server.
