MAKE SURE YOU HAVE REDIS RUNNING

Obviously you need a redis server running,

Check you have one running,

redis-cli ping

RUN

First, make sure you have the go library

go get -u -v github.com/go-redis/redis

Then run,

go run redis.go

Your output should be,

PONG <nil>
jeff monkey
key2 does not exist

CHECK KEY/VALUE USING REDIS-CLI

Check your key value using command line,

redis-cli
get jeff

SET/GET KEY/VALUES IN GO

Lets dive into the code.

CREATE A CONNECTION TO REDIS SERVER

client := redis.NewClient(&redis.Options{
    Addr:     "localhost:6379",
    Password: "", // no password set
    DB:       0,  // use default DB
})

pong, err := client.Ping().Result()
fmt.Println(pong, err)
// Output: PONG <nil>

SET A KEY/VALUE

err = client.Set("jeff", "monkey", 0).Err()

GET A KEY/VALUE

val, err := client.Get("jeff").Result()
fmt.Println("jeff", val)
// Output: jeff monkey
