How do I set up a Redis cluster using Go?

To set up a Redis cluster using Go, you'll need to use the go-redis library. First, install it using go get github.com/go-redis/redis/v8.

What are the steps to configure the cluster nodes?

You need to initialize the cluster with at least three master nodes. Use the ClusterOptions to configure the nodes and connect to them.

Can you show me a sample code for connecting to the cluster?

Sure! Here's a simple example:

package main

import (
	"context"
	"github.com/go-redis/redis/v8"
)

func main() {
	ctx := context.Background()
	clusterOptions := &redis.ClusterOptions{
		Addrs: []string{"localhost:7000", "localhost:7001", "localhost:7002"},
	}
	client := redis.NewClusterClient(clusterOptions)
	defer client.Close()
}

What should I do if I encounter connection issues?

Check if the Redis nodes are running and accessible. Also, ensure that your firewall settings allow connections on the Redis ports.
