启动server

执行redis-server.exe

C:\Program Files\Redis>redis-server.exe[12092] 10 Aug 13:29:08.616 # Warning: no config file specified, using the default config.

客户端测试

执行redis-cli.exe

127.0.0.1:6379> set name duoke360OK127.0.0.1:6379> get name"duoke360"127.0.0.1:6379>

装置go-redis库

应用go get命令装置

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

初始化数据库连贯

package mainimport (    "context"    "github.com/go-redis/redis"    "time")// 申明一个全局的rdb变量var rdb *redis.Client// 初始化连贯func initClient() (err error) {    rdb = redis.NewClient(&redis.Options{        Addr:     "localhost:6379",        Password: "", // no password set        DB:       0,  // use default DB    })        ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)    defer cancel()    _, err = rdb.Ping(ctx).Result()    if err != nil {        return err    }    return nil}func main() {    initClient()}

连贯Redis哨兵模式

func initClient()(err error){    rdb := redis.NewFailoverClient(&redis.FailoverOptions{        MasterName:    "master",        SentinelAddrs: []string{"x.x.x.x:26379", "xx.xx.xx.xx:26379", "xxx.xxx.xxx.xxx:26379"},    })    _, err = rdb.Ping().Result()    if err != nil {        return err    }    return nil}

连贯Redis集群模式

func initClient()(err error){    rdb := redis.NewClusterClient(&redis.ClusterOptions{        Addrs: []string{":7000", ":7001", ":7002", ":7003", ":7004", ":7005"},    })    _, err = rdb.Ping().Result()    if err != nil {        return err    }    return nil}

字符串get、set

package mainimport (    "context"    "fmt"    "github.com/go-redis/redis"    "time")// 申明一个全局的rdb变量var rdb *redis.Clientvar ctx context.Contextvar cancel context.CancelFunc// 初始化连贯func initClient() (err error) {    rdb = redis.NewClient(&redis.Options{        Addr:     "localhost:6379",        Password: "", // no password set        DB:       0,  // use default DB    })    ctx, cancel = context.WithTimeout(context.Background(), 5*time.Second)    _, err = rdb.Ping(ctx).Result()    if err != nil {        return err    }    return nil}func testStringGetSet() {    err := rdb.Set(ctx,"score", 100, 0).Err()    if err != nil {        fmt.Printf("set score failed, err:%v\n", err)        return    }    val, err := rdb.Get(ctx,"score").Result()    if err != nil {        fmt.Printf("get score failed, err:%v\n", err)        return    }    fmt.Println("score", val)    val2, err := rdb.Get(ctx,"name").Result()    if err == redis.Nil {        fmt.Println("name does not exist")    } else if err != nil {        fmt.Printf("get name failed, err:%v\n", err)        return    } else {        fmt.Println("name", val2)    }    defer cancel()}

测试

func main() {    initClient()    testStringGetSet()}

运行后果

zset示例

func testSet()  {    zsetKey := "book_price"    languages := []redis.Z{        redis.Z{Score: 90.0, Member: "Golang"},        redis.Z{Score: 98.0, Member: "Java"},        redis.Z{Score: 95.0, Member: "Python"},        redis.Z{Score: 97.0, Member: "JavaScript"},        redis.Z{Score: 99.0, Member: "C/C++"},    }    // ZADD    num, err := rdb.ZAdd(ctx,zsetKey, languages).Result()    if err != nil {        fmt.Printf("zadd failed, err:%v\n", err)        return    }    fmt.Printf("zadd %d succ.\n", num)    // 把Golang的分数加10    newScore, err := rdb.ZIncrBy(ctx,zsetKey, 10.0, "Golang").Result()    if err != nil {        fmt.Printf("zincrby failed, err:%v\n", err)        return    }    fmt.Printf("Golang's score is %f now.\n", newScore)    // 取分数最高的3个    ret, err := rdb.ZRevRangeWithScores(ctx,zsetKey, 0, 2).Result()    if err != nil {        fmt.Printf("zrevrange failed, err:%v\n", err)        return    }    for _, z := range ret {        fmt.Println(z.Member, z.Score)    }    // 取95~100分的    op := redis.ZRangeBy{        Min: "95",        Max: "100",    }    ret, err = rdb.ZRangeByScoreWithScores(ctx,zsetKey, op).Result()    if err != nil {        fmt.Printf("zrangebyscore failed, err:%v\n", err)        return    }    for _, z := range ret {        fmt.Println(z.Member, z.Score)    }}func main() {    initClient()    testStringGetSet()}
