初涉AWS 之 ElasticCache——Redis在.Net中的用法

拿到一个测试aws帐号开始捣鼓。

aws上可用ElasticCache包括Redis和MemCached，此篇说redis，下篇讲MemCached。

什么是aws Elasticcache

其中包括基本的介绍和配置信息入门。

在.Net客户端上安装配置相关组件

NuGet中下载Amazon.ElastiCacheCluster程序包并引用

在Appconfig中进行相应配置

 1 <configSections>
 2     <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
 3     <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
 4     <section name="clusterclient" type="Amazon.ElastiCacheCluster.ClusterConfigSettings, Amazon.ElastiCacheCluster" />
 5   <section name="membase" type="Membase.Configuration.MembaseClientSection, Membase" /></configSections>
 6   <clusterclient>
 7     <!-- the hostname and port values are from step 1 above -->
 8     <endpoint hostname="{ip地址}" port="6379" />
 9     <!--bigdata-redis.xdnqsx.0001.cnn1.cache.amazonaws.com.cn-->
10   </clusterclient>

appconfig

Q问题，为何不能用aws控制台中的DNS，必需要用ip地址。

接着是client中redis connection的修改，代码实现起来比azure要方便一些，固然aws对加密这一块作的不如azure，sql 的connection也是如此，多是并不担忧？

 1 private static readonly Lazy<ConnectionMultiplexer> LazyConnection = new Lazy<ConnectionMultiplexer>(() =>
 2         {
 3             _logger.Info(LoggerSourceName, "Begin to create Redis connection");
 4 
 5             //read connection information from storage/configuration-redis/Redis.config           
 6             string redisConnectionString;
 7             redisConnectionString = DANCode1Config.ClusterClientHostname + ":" + DANCode1Config.ClusterClientPort;
 8 
 9             ConfigurationOptions options = ConfigurationOptions.Parse(redisConnectionString);
10             //options.ConnectTimeout = 60 * 1000;
11             options.SyncTimeout = 60 * 1000;
12             options.ResponseTimeout = 60 * 1000;
13 
14 
15             ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(options);
16             redis.ConfigurationChanged += redis_ConfigurationChanged;
17             redis.ConfigurationChangedBroadcast += redis_ConfigurationChangedBroadcast;
18             redis.ConnectionFailed += redis_ConnectionFailed;
19             redis.ConnectionRestored += redis_ConnectionRestored;
20             return redis;
21         });

redis connection

配置完后，全部原先读写redis的地方都不须要更改。
