Я пытаюсь создать тестовый проект, используя сервер Redis , установленный на виртуальной машине Linux Ubuntu, через виртуальный ящик.
Компьютер с Linux связан с локальной сетью через мостовой адаптер Virtual Box, который работает на моей машине с Windows 7.
Linux Machine - новый, только что созданный, я сделал
sudo ufw enable
и затем перезапустите сервер Redis (в Linux).
Теперь вот моя попытка из Windows
C:\Users\my-user>nmap -p 6379 10.14.30.51
Starting Nmap 7.70 ( https://nmap.org ) at ...
Nmap scan report for 10.14.30.51
Host is up (0.0010s latency).
PORT STATE SERVICE
6379/tcp filtered redis
MAC Address: 08:00:27:98:94:49 (Oracle VirtualBox virtual NIC)
Я создал новый проект .NET MVC с моей Visual Studio 2017, и вот код контроллера:
using StackExchange.Redis;
using System.Web.Mvc;
namespace RedisClient.Controllers
{
public class HomeController : Controller
{
public struct Server {
public const string IP = "10.14.30.51";
public const int Port = 6379;
}
public ActionResult Index() { return View(); }
public ActionResult About()
{
ConnectionMultiplexer redis =
ConnectionMultiplexer.Connect($"{Server.IP}:{Server.Port}");
IDatabase db = redis.GetDatabase();
string value = "abcdefg";
db.StringSet("mykey", value);
value = db.StringGet("mykey");
ViewBag.Message = $"The value is '{value}'";
return View();
}
public ActionResult Contact() { return View(); }
}
}
Итак, когда я нажимаю на ссылку «О программе», я получаю следующую ошибку в строке .Connect
Не удалось подключиться к серверу (-ам) redis. Невозможно подключиться
10.14.30.51:6379/Интерактивный, Инициализация / NotStarted, последний: НЕТ,
origin: BeginConnectAsync, ожидающий: 0, последний раз прочитанный: 0s тому назад,

доступно, последнее сердцебиение: никогда, глобально: 0 с назад, v: 2.0.601.3402
- EDIT
Выход
var log = new StringWriter();
ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(
$"{Server.IP}:{Server.Port},abortConnect=False", log);
var logOutput = log.ToString();
является следующим:
