Windows Redis Sentinel Configuration

Redis Sentinel is a tool that helps manage Redis instances in a high-availability setup. It monitors the health of Redis instances and can perform automatic failover if a master node goes down. In this article, we will discuss how to configure Redis Sentinel on Windows.

Installation

Before setting up Redis Sentinel, you need to have Redis installed on your Windows machine. You can download Redis for Windows from the official website and follow the installation instructions.

Configuration

To configure Redis Sentinel on Windows, you need to create a configuration file for each sentinel instance. Here is an example configuration file (sentinel.conf):

port 26379
dir "D:/redis/sentinel"
sentinel monitor mymaster 127.0.0.1 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 60000
sentinel parallel-syncs mymaster 1

In this configuration file:

  • port: Port number for the Redis Sentinel instance.
  • dir: Directory where the Redis Sentinel data is stored.
  • sentinel monitor: Configures the Redis master instance that this sentinel should monitor.
  • sentinel down-after-milliseconds: Specifies the time (in milliseconds) after which the sentinel considers a master node as down.
  • sentinel failover-timeout: Time (in milliseconds) after which a failover is triggered.
  • sentinel parallel-syncs: Number of parallel syncs that can happen during a failover.

Starting Redis Sentinel

After creating the configuration file, you can start the Redis Sentinel instance by running the following command in the command prompt:

redis-server D:/redis/sentinel/sentinel.conf --sentinel

Replace D:/redis/sentinel/sentinel.conf with the path to your configuration file.

Monitoring Redis Instances

Once Redis Sentinel is up and running, you can monitor your Redis instances using the redis-cli tool. Connect to the sentinel instance using the following command:

redis-cli -p 26379

You can check the status of your Redis instances by running the sentinel master command.

Conclusion

In this article, we discussed how to configure Redis Sentinel on Windows. By following the steps outlined in this guide, you can set up a high-availability Redis setup that automatically handles failovers in case of a master node failure.

Remember to regularly monitor your Redis instances and perform necessary maintenance tasks to ensure the smooth operation of your Redis cluster. Feel free to explore more advanced configurations and features provided by Redis Sentinel to optimize the performance and reliability of your Redis setup.
