  • C#采用rabbitMQ搭建分布式日志系统

    网上对于java有很多开源的组件可以搭建分布式日志系统,我参考一些组件自己开发一套简单的分布式日志系

    全部使用采用.NET进行开发,所用技术:MVC、EF、RabbitMq、MySql、Autofac

    整体构架如下:

    主要采用的RabbitMq进行处理,下面我主要讲讲.NET下运用RabbitMq

    1.RabbitMQ Erlang 的安装,网上很多介绍,我这里就不多少了,请参考https://jingyan.baidu.com/article/a17d5285173ce68098c8f2e5.html

    备注:安装好后一定注意保持.erlang.cookie这个文件的一致,在用户目录和windows下面。

    2.RabbitMQ是使用,先安装RabbitMQ.Client,在VS中程序管理装入

    RabbitMQ的辅助类

        /// RabbitMQ消息队列处理
        /// </summary>
        public class RabbitMQHelper
        {
            /// <summary>
            /// rabbitMQ地址
            /// </summary>
            private string HostName = "localhost";   //ConfigurationManager.AppSettings["RabbitMQHostName"];
            /// <summary>
            /// 账号

            private string UserName = "guest";    //ConfigurationManager.AppSettings["RabbitMQUserName"];

                {

    3.在生成服务器只需要调用SendMsg将日志文件写入消息队列

    4.在日志处理服务器采用 NLog进行日志持久化处理,目前采用2台服务,采用RabbitMQ公平分发到2台日志服务器中,最后进行持久化处理,NLog的使用这里就不作说明

    如果对于日志处理有更好的方案欢迎指出,谢谢
