没有连接到redis

772

我正在尝试建立从 Redis 到本地主机的连接。

string connectionString = configuration.GetConnectionString("RedisConnection");

_redis = ConnectionMultiplexer.Connect(connectionString); //Исключение

_database = _redis.GetDatabase();

连接字符串本身来自用户机密：

"ConnectionStrings:RedisConnection": "redis://localhost:6379/",

字符串本身肯定不为空

但在 C# 中我得到这个异常：

StackExchange.Redis.RedisConnectionException HResult=0x80131500 Message=无法连接到 Redis 服务器。现在连接时出错。要允许此多路复用器继续重试直到能够连接，请在连接字符串中使用 abortConnect=false 或 AbortOnConnectFail=false; 在你的代码中。源 = StackExchange.Redis StackTrace：位于 StackExchange.Redis.ConnectionMultiplexer.ConnectImpl（ConfigurationOptions 配置、TextWriter 日志、Nullable1 serverType, EndPointCollection endpoints) at StackExchange.Redis.ConnectionMultiplexer.Connect(ConfigurationOptions configuration, TextWriter log) at StackExchange.Redis.ConnectionMultiplexer.Connect(String configuration, TextWriter log) at FileCryptWeb.DataBase.Redis.RedisDbContext..ctor() in C:\Users\Stewi\Source\Repos\air2921\FileCryptWeb\FileCryptWeb\DataBase\Redis\RedisDbContext.cs:line 19 at System.RuntimeMethodHandle.InvokeMethod(Object target, Void** arguments, Signature sig, Boolean isConstructor) at System.Reflection.ConstructorInvoker.Invoke(Object obj, IntPtr* args, BindingFlags invokeAttr) at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitConstructor(ConstructorCallSite constructorCallSite, RuntimeResolverContext context) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitCache(ServiceCallSite callSite, RuntimeResolverContext context, ServiceProviderEngineScope serviceProviderEngine, RuntimeResolverLock lockType) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScopeCache(ServiceCallSite callSite, RuntimeResolverContext context) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor2.VisitCallSite（ServiceCallSite callSite，TArgument参数）在Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.Resolve（ServiceCallSite callSite，ServiceProviderEngineScope范围）在Microsoft.Extensions.DependencyInjection.ServiceLookup.DynamicServiceProviderEngine。<>c__Di splayClass2_0.b__0（ServiceProviderEngineScope范围）在 Microsoft.Extensions.DependencyInjection.ServiceProvider.GetService（类型 serviceType，ServiceProviderEngineScope serviceProviderEngineScope）在 Microsoft.Extensions.DependencyInjection.ActivatorUtilities.GetService（IServiceProvider sp，类型 type，类型 requiredBy，布尔 isDefaultParameterRequired）在 Microsoft.AspNetCore.Mvc.Controllers.Con trollerFactoryProvider。<>c__DisplayClass6_0.g__CreateController|0(ControllerContextcontrollerContext)，位于 Microsoft.AspNetCore.Mvc。Microsoft.AspNetCore.Mvc.Infrastruct.ControllerActionInvoker.InvokeInnerFilterAsync() 处的 Infrastructure.ControllerActionInvoker.Next(State& next、Scope& range、Object& state、Boolean& isCompleted)

尝试启动服务器

结果发现解决方案很奇怪：

我做了什么：

我从磁盘中删除了 Redis 并使用本指南安装了它 https://www.youtube.com/watch?v=_nFwPTHOMIY&ab_channel=Redis
使用此命令启动服务器

sudo service redis-server 启动
将连接字符串更改为：

本地主机：6379，abortConnect = false

重要提示，在我的例子中，更改线路并尝试连接到安装在磁盘上的 Redis 并不成功。按照指南安装后，一切正常。虽然乍一看并没有什么区别。

另外，在按照指南安装之前，我尝试从网站安装Redis，版本7.2.1也没有帮助
