红帽致力于替换我们的代码、文档和 Web 属性中存在问题的语言。我们从这四个术语开始：master、slave、黑名单和白名单。由于此项工作十分艰巨，这些更改将在即将推出的几个发行版本中逐步实施。有关更多详情，请参阅我们的首席技术官 Chris Wright 提供的消息。

Data Grid 提供了一个安装软件包，用于在 Windows 上安装 Hot Rod .NET/C# 客户端。

先决条件

  • Microsoft 支持 .NET Framework 的任何操作系统
  • .NET Framework 4.6.2 或更高版本
  • Windows Visual Studio 2015 或更高版本

流程

  1. 从 Data Grid 软件下载 下载 redhat-datagrid-<version>-hotrod-dotnet-client.msi。
  2. 为 Hot Rod .NET/C# 客户端启动 MSI 安装程序，并通过安装过程跟踪交互式向导。

1.2. 配置和远程缓存管理器 API

使用 ConfigurationBuilder API 配置 Hot Rod .NET/C# 客户端连接和 RemoteCacheManager API，以获取和配置远程缓存。

基本配置

using Infinispan.HotRod;
using Infinispan.HotRod.Config;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace simpleapp
{
    class Program
    {
        static void Main(string[] args)
        {
            ConfigurationBuilder builder = new ConfigurationBuilder();
            // Connect to a server at localhost with the default port.
            builder.AddServer()
                .Host(args.Length > 1 ? args[0] : "127.0.0.1")
                .Port(args.Length > 2 ? int.Parse(args[1]) : 11222);
            Configuration config = builder.Build();
            // Create and start a RemoteCacheManager to interact with caches.
            RemoteCacheManager remoteManager = new RemoteCacheManager(conf);
            remoteManager.Start();
            IRemoteCache<string,string> cache=remoteManager.GetCache<string, string>();
            cache.Put("key", "value");
            Console.WriteLine("key = {0}", cache.Get("key"));
            remoteManager.Stop();
        }
    }
}

身份验证

ConfigurationBuilder builder = new ConfigurationBuilder();
// Add a server with specific connection timeouts
builder.AddServer().Host("127.0.0.1").Port(11222).ConnectionTimeout(90000).SocketTimeout(900);
// ConfigurationBuilder has fluent interface, options can be appended in chain.
// Enabling authentication with server name "node0",
// sasl mech "PLAIN", user "supervisor", password "aPassword", security realm "aRealm"
builder.Security().Authentication().Enable().ServerFQDN("node0")
    .SaslMechanism("PLAIN").SetupCallback("supervisor", "aPassword", "aRealm");
Configuration c = conf.Build();

Encryption

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.AddServer().Host("127.0.0.1").Port(11222);
// Get configuration builder for encryption
SslConfigurationBuilder sslBuilder = conf.Ssl();
// Enable encryption and provide client certificate
sslBuilder.Enable().ClientCertificateFile("clientCertFilename");
// Provide server cert if server needs to be verified
sslBuilder.ServerCAFile("serverCertFilename");
Configuration c = conf.Build();

跨站点故障切换

ConfigurationBuilder builder = new ConfigurationBuilder();
  builder.AddServer().Host("127.0.0.1").Port(11222);
  // Configure a remote cluster and node when using cross-site failover.
  builder.AddCluster("nyc").AddClusterNode("192.0.2.0", 11322);

接近缓存

ConfigurationBuilder builder = new ConfigurationBuilder();
  builder.AddServer().Host("127.0.0.1").Port(11222);
  // Enable near-caching for the client.
  builder.NearCache().Mode(NearCacheMode.INVALIDATED).MaxEntries(10);
