mysql master/slave介绍及配置
Master-Slave的数据库机构解决了很多问题,特别是read/write比较高的web2.0应用: 1、写操作全部在Master结点执行,并由Slave数据库结点定时(默认60s)读取Master的bin-log 2、将众多的用户读请求分散到更多的数据库节点,从而减轻了单点的压力 这是对Replication的最基本陈述,这种模式的在系统Scale-out方案中很有引力(如有必要,数据可以先进行Sharding,再使用replication)。

MySQL学习笔记--复制建立新Slave的方法:克隆Master\Slave
即建立新的Slave的方法 前面已经在文章“简单配置MySQL复制”中配置Slave时,没有说明复制从哪里开始,所以Slave是从头开始读取Master的binlog日志的。 但如果Master已经运行一段时间,要重现之前所有日志的事件,而且日志可能已经丢失或转储。所以我们一种通用的做法是--不从头开始复制日志。 而是对Slave进行一次性初始化操作,建立新的Slave(又称引导Slave)

一、概述 Mysql Replication(复制) 即 主从同步(Master/Slave),主要用于数据库的备份,负载均衡,读写分离等。 1、数据复制技术有以下一些特点: (1)    数据分布 (2)    负载平衡(load balancing),读写分离,主写从读 (3)    备份 (4)    高可用性(high availability)和容错 2、复制如何工作
Hadoop搭建过程中实现master与slave无密码登录
一,集群部署简介 1.hadoop简介  Hadoop是Apache软件基金会旗下的一个开源分布式计算平台。以Hadoop分布式文件系统HDFS(Hadoop Distributed Filesystem)和MapReduce(Google MapReduce的开源实现)为核心的Hadoop为用户提供了系统底层细节透明的分布式基础架构。 对于Hadoop的集群来讲,可以分成两大类角色

MySQL Master Slave构架 spring3 整合
MySQL Master Slave 集群构架和spring整合,里面实现的是动态切换数据源,大家都是知道,spring2之后添加AbstractRoutingDataSource这个东西,这个就可以实现切换数据源,实现思路是:先按照<<搭建MySQL的MasterSlave架构.doc>>(我上传有资源),搭建好,然后动态切换数据源的时候,利用aop,每次查询的时候,就取Slave的数据源,更新 删除 插入的时候取Master的数据源,这样就能实现动态切换,分数给的有点高,但是我上传的资源都是原创
dpvs源代码分析——master和slave之间通信
小胖我在阅读dpvs源代码的过程中,发现很多模块调用msg_type_mc_register函数或msg_type_register函数来注册dpvs_msg_type结构体,结构体定义如下: /* unicast only needs UNICAST_MSG_CB, * while multicast need both UNICAST_MSG_CB and MULTICAST_MSG_C...
