Redis是一个用的比较广泛的Key/Value的内存数据库,也是最快的key-value分布式缓存之一。

一、Redis安装
选择一个版本进行下载,压缩包中包括32位和64位的安装工具,或者直接使用安装版的进行安装,都是一样的,这里使用的是安装版的,安装结果如图:
安装完后会在系统服务中出现一个Redis Server的系统服务。
redis-server.exe:服务器的daemon启动程序。
redis.conf:配置文件。
redis-cli.exe:命令行客户端。
redis-check-dump.exe:本地数据库检查
redis-check-aof.exe:更新日志检查
redis-benchmark.exe:性能测试工具,测试Redis在你的系统及你的配置下的读写性能。
二、Redis配置
1. port 端口号,例如6379
2. bind 实例绑定的访问地址127.0.0.1
3. requirepass 访问的密码
4. maxheap 记得把这个配置节点打开,否者redis 服务无法启动。例如maxheap 1024000000
5. timeout:请求超时时间
6. logfile:log文件位置
7. databases:开启数据库的数量
8. dbfilename:数据快照文件名(只是文件名,不包括目录)
三、Redis使用
在Redis的安装目录下找到redis-cli.exe文件,双击启动它:
测试OK,至此Redis安装到此结束了,接下来是在C#中的实际运用。
二、Redis实战
1.建立项目,引用ServiceStack.Redis相关的四个类库。
2.配置文件
<!-- redis Start --> <add key="SessionExpireMinutes" value="180" /> <add key="redis_server_session" value="127.0.0.1:6379" /> <add key="redis_max_read_pool" value="3" /> <add key="redis_max_write_pool" value="1" /> <!--redis end-->
3.创建一个Redis操作的公用类RedisCacheHelper
using ServiceStack.Redis; using System; using System.Collections.Generic; using System.Configuration; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication { class RedisCacheHelper { private static readonly PooledRedisClientManager pool = null; private static readonly string[] redisHosts = null; public static int RedisMaxReadPool = int.Parse(ConfigurationManager.AppSettings["redis_max_read_pool"]); public static int RedisMaxWritePool = int.Parse(ConfigurationManager.AppSettings["redis_max_write_pool"]); static RedisCacheHelper() { var redisHostStr = ConfigurationManager.AppSettings["redis_server_session"]; if (!string.IsNullOrEmpty(redisHostStr)) { redisHosts = redisHostStr.Split(‘,‘); if (redisHosts.Length > 0) { pool = new PooledRedisClientManager(redisHosts, redisHosts, new RedisClientManagerConfig() { MaxWritePoolSize = RedisMaxWritePool, MaxReadPoolSize = RedisMaxReadPool, AutoStart = true }); } } } public static void Add<T>(string key, T value, DateTime expiry) { if (value == null) { return; } if (expiry <= DateTime.Now) { Remove(key); return; } try { if (pool != null) { using (var r = pool.GetClient()) { if (r != null) { r.SendTimeout = 1000; r.Set(key, value, expiry - DateTime.Now); } } } } catch (Exception ex) { string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key); } } public static void Add<T>(string key, T value, TimeSpan slidingExpiration) { if (value == null) { return; } if (slidingExpiration.TotalSeconds <= 0) { Remove(key); return; } try { if (pool != null) { using (var r = pool.GetClient()) { if (r != null) { r.SendTimeout = 1000; r.Set(key, value, slidingExpiration); } } } } catch (Exception ex) { string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key); } } public static T Get<T>(string key) { if (string.IsNullOrEmpty(key)) { return default(T); } T obj = default(T); try { if (pool != null) { using (var r = pool.GetClient()) { if (r != null) { r.SendTimeout = 1000; obj = r.Get<T>(key); } } } } catch (Exception ex) { string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "获取", key); } return obj; } public static void Remove(string key) { try { if (pool != null) { using (var r = pool.GetClient()) { if (r != null) { r.SendTimeout = 1000; r.Remove(key); } } } } catch (Exception ex) { string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "删除", key); } } public static bool Exists(string key) { try { if (pool != null) { using (var r = pool.GetClient()) { if (r != null) { r.SendTimeout = 1000; return r.ContainsKey(key); } } } } catch (Exception ex) { string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "是否存在", key); } return false; } } }
4.程序测试
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication { class Program { static void Main(string[] args) { Console.WriteLine("Redis写入缓存:"); RedisCacheHelper.Add("name1", "test1", DateTime.Now.AddDays(1)); Console.WriteLine("Redis获取缓存:"); string str = RedisCacheHelper.Get<string>("name1"); Console.WriteLine(str); Console.ReadKey(); } } }
5.输入结果
