Redis connection: Received error "dial tcp [::1]:6379: connect: connection refused" when attempting to Dial with Redigo

Question

I'm trying to run

conn, err := redis.Dial("tcp", "localhost:6379")
if err != nil {
    log.Fatal(err)
}

using redis Redigo, the golang driver. I have not changed any configurations or anything. My error is:

go run redisgotest.go
2019/11/19 15:51:05 dial tcp [::1]:6379: connect: connection refused
exit status 1
