Redis【REmote DIctionary Server】作为当前比较流行的NoSql数据库，以其高性能，高可用的的特点，应用越来越广泛，深得各大企业和开发人员的青睐。 本文主要以一个简单的小例子，简述ServiceStack.Redis动态库在Redis方面的相关应用，仅供学习分享使用，如有不足之处，还请指正。
相关开发环境，如下所示：
在C#开发中，主要通过NuGet包管理器，来安装ServiceStack.Redis动态库，目前版本为5.10.4，如下所示：
关于C#调用Redis相关示例截图，如下所示：
关于Redis操作的核心代码，主要分两部分：Redis客户端管理类，Redis客户端操作类。
Redis客户端管理类，主要通过Redis客户端连接池【PooledRedisClientManager】创建客户端对象【IRedisClient】，如下所示：
1 using ServiceStack.Redis; 2 using System; 3 using System.Collections.Generic; 4 using System.Linq; 5 using System.Text; 6 using System.Threading.Tasks; 7 8 namespace DemoRedis 9 { 10 /// <summary> 11 /// Redis客户端管理类 12 /// </summary> 13 public static class RedisManager 14 { 15 private static PooledRedisClientManager clientManager; 16 17 /// <summary> 18 /// 初始化信息 19 /// </summary> 20 private static void initInfo() 21 { 22 string ipaddr = System.Configuration.ConfigurationManager.AppSettings["ipaddr"]; 23 string port = System.Configuration.ConfigurationManager.AppSettings["port"]; 24 string host = string.Format("{0}:{1}", ipaddr, port); 25 initInfo(new string[] { host }, new string[] { host }); 26 } 27 28 /// <summary> 29 /// 初始化Redis客户端管理 30 /// </summary> 31 /// <param name="readWriteHosts"></param> 32 /// <param name="readOnlyHosts"></param> 33 private static void initInfo(string[] readWriteHosts, string[] readOnlyHosts) 34 { 35 clientManager = new PooledRedisClientManager(readWriteHosts, readOnlyHosts, new RedisClientManagerConfig 36 { 37 MaxWritePoolSize = 5, // “写”链接池链接数 38 MaxReadPoolSize = 5, // “读”链接池链接数 39 AutoStart = true, 40 }); 41 } 42 43 public static IRedisClient getRedisClient() 44 { 45 if (clientManager == null) 46 { 47 initInfo(); 48 } 49 return clientManager.GetClient(); 50 } 51 52 } 53 54 55 }
Redis客户端操作类，主要包括字符串（String），列表（List），哈希结构（Hash）,集合（Set），有序集合（Sorted Set）等相关操作功能的封装，如下所示：
1 using ServiceStack.Redis; 2 using System; 3 using System.Collections.Generic; 4 using System.Linq; 5 using System.Text; 6 using System.Threading.Tasks; 7 8 namespace DemoRedis 9 { 10 public class RedisHelper:IDisposable 11 { 12 private IRedisClient client;

如果在Redis服务端和客户端不在同一个电脑上，可能会出现无法访问的情况，前端报连接超时错误。则可能是服务端防火墙限制。需要执行如下命令即可：
1 [root@localhost bin]# /sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
另外Redis.conf配置文件中，关于bind配置，默认bind为127.0.0.1只允许本机访问，需要修改，如下所示：
1 # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2 bind 127.0.0.1 192.168.127.131
其中：192.168.127.131 为服务器IP地址。

大漠孤烟直，长河落日圆。
萧关逢候骑，都护在燕然。
