)

var pool *redis.Pool;
func init(){

		MaxIdle: 8,
		MaxActive:0,
		IdleTimeout: 100,
		Dial: func() (redis.Conn, error) {
			return redis.Dial("tcp","localhost:6379")
		},
	}
}
func main(){
	conn := pool.Get();
	conn.Do("set","name","lisoi");
	s, err := redis.String(conn.Do("get","name"));
	if err !=nil {
		fmt.Println("is error");
