**一、配置环境变量**

1、表示go语言依赖环境的目录、其实go有一个默认地址、也可以使用默认地址  
2、表示go语言安装目录

上图所示、将go-redis通过git下载放入目录的地方。git下载自动生成redis目录、需要自己创建go-redis目录、再将redis拷贝到go-redis目录中

$ git clone https://github.com/go-redis/redis.git

目的为了解决

也为了解决 VS Code 中 golang.org 被墙导致的 Go 插件安装失败问题：

二、运行go案例

package main
     
    import (
        "fmt"
        "github.com/go-redis/redis"
        "time"
    )
     
    func main() {
        ExampleNewClient()
        ExampleClient()
    }
     
    //ping pong测试
    func ExampleNewClient() {
        client := redis.NewClient(&redis.Options{
            Addr:     "47.98.182.201:8008",
            Password: "124", // no password set
            DB:       0,  // use default DB
        })
     
        pong, err := client.Ping().Result()
        fmt.Println(pong, err)
        // Output: PONG <nil>
    }
     
    //set和get测试
    func ExampleClient() {
        client := redis.NewClient(&redis.Options{
            Addr:     "47.98.182.201:8008",
            Password: "124", // no password set
            DB:       0,  // use default DB
        })
        //第三个参数是过期时间
        err := client.Set("name", "你好", 10*time.Second).Err()
        if err != nil {
            panic(err)
        }
     
        val, err := client.Get("name").Result()
        if err != nil {
            panic(err)
        }
        fmt.Println("name:", val)
        //检测key是否存在
        val2, err := client.Get("name").Result()
        if err == redis.Nil {
            fmt.Println("name 不存在")
        } else if err != nil {
            panic(err)
        } else {
            fmt.Println("name", val2)
        }
    }
