Redis 客户端配置及示例

一、实现redis自定义配置节点

　　1.redis自定义配置节点

  <configSections>
    <section name ="RedisConfig" type="Amy.Toolkit.RedisCache.SectionHandler"/>
  </configSections>

  <RedisConfig>
    <add key="ReadWriteHosts" value="192.168.1.101:6379"></add>
    <add key="ReadOnlyHosts" value="192.168.1.101:6379"></add>
    <add key="MaxWritePoolSize" value="5"></add>
    <add key="MaxReadPoolSize" value="5"></add>
  </RedisConfig>

　　2.实现自定义配置功能

    public class Config
    {
        /// <summary>
        /// “写”服务器地址
        /// </summary>
        public string[] ReadWriteHosts { get; set; }

        /// <summary>
        /// “读”服务器地址
        /// </summary>
        public string[] ReadOnlyHosts { get; set; }

        /// <summary>
        /// “写”链接池链接数
        /// </summary>
        public int MaxWritePoolSize { get; set; }

        /// <summary>
        /// “读”链接池链接数
        /// </summary>
        public int MaxReadPoolSize { get; set; }
    }

    public class SectionHandler : IConfigurationSectionHandler
    {
        public object Create(object parent, object configContext, XmlNode section)
        {
            Config config = new Config();

            //解析配置文件信息，返回对象
            if (section != null)
            {
                foreach (XmlNode item in section.ChildNodes)
                {
                    switch (item.Attributes["key"].InnerText)
                    {
                        case "ReadWriteHosts":
                            config.ReadWriteHosts = item.Attributes["value"].InnerText.Split(‘;‘);
                            break;
                        case "ReadOnlyHosts":
                            config.ReadOnlyHosts = item.Attributes["value"].InnerText.Split(‘;‘);
                            break;
                        case "MaxWritePoolSize":
                            config.MaxWritePoolSize = string.IsNullOrEmpty(item.Attributes["value"].InnerText) ? 1 : item.Attributes["value"].InnerText.ToInt32();
                            break;
                        case "MaxReadPoolSize":
                            config.MaxReadPoolSize = string.IsNullOrEmpty(item.Attributes["value"].InnerText) ? 1 : item.Attributes["value"].InnerText.ToInt32();
                            break;
                        default:
                            config.ReadWriteHosts = new string[] { };
                            config.ReadOnlyHosts = new string[] { };
                            config.MaxWritePoolSize = 1;
                            config.MaxReadPoolSize = 1;
                            break;
                    }

                }
            }
            return config;
        }
    }

StackExchange.Redis客户端读写主从配置，以及哨兵配置。

今天简单分享一下StackExchange.Redis客户端中配置主从分离以及哨兵的配置. 关于哨兵如果有不了解的朋友,可以看我之前的一篇分享,当然主从复制文章也可以找到.http://www.cnblogs.com/tdws/tag/NoSql/ 为什么要有这篇分享呢,是因为我之前也有一些疑问,相信学习Redis的朋友都有过相同的疑问. 在代码中,如何分别操作主从数据库?,也就是说,如何只向主数据库写,而读取只向从服务器读.我目前给出的解决方案就是有关Set命令使用主服务器地址,关于Get的命

redis主从配置&lt;转&gt;

一.Redis的Replication: 这里首先需要说明的是,在Redis中配置Master-Slave模式真是太简单了.相信在阅读完这篇Blog之后你也可以轻松做到.这里我们还是先列出一些理论性的知识,后面给出实际操作的案例.    下面的列表清楚的解释了Redis Replication的特点和优势.    1). 同一个Master可以同步多个Slaves.    2). Slave同样可以接受其它Slaves的连接和同步请求,这样可以有效的分载Master的同步压力.因此我们可以将Re

Redis安装配置与Jedis访问数据库

一.NOSQL概要 NoSQL(NoSQL = Not Only SQL ),意即“不仅仅是SQL”,泛指非关系型的数据库.NoSQL数据库的四大分类 键值(Key-Value)存储数据库 这一类数据库主要会使用到一个哈希表,这个表中有一个特定的键和一个指针指向特定的数据.Key/value模型对于IT系统来说的优势在于简单.易部署.但是如果DBA只对部分值进行查询或更新的时候,Key/value就显得效率低下了. 举例如:Tokyo Cabinet/Tyrant, Redis, Voldemo

Redis安装和使用示例

Redis是目前众多NoSQL产品中非常有特点的一款,支持的数据类型和方法都非常丰富,做为一款具备持久化功能的软件,实际使中更多却是将其做为cache. 三思在个人的测试环境中安装使用了两三天,这期间尽管文档看了不少,但其实收获不多,不过对于NoSQL产品的整体看法一直没变,我觉着各类型NoSQL产品都还只是工具,并且是小工具,称不上产品.小工具能起大作用这不假(redis目前在国内最知名的案例应该是新浪微博),但前提是为其找到适合的应用场景,深入的了解才能用好它. 本文简要描述了linux环境
