生产MongoDB分片与集群方案.docx

生产MongoDB 分片与集群方案【编者的话】Mongo DB 是目前在IT行业非常流行的一种非关系型数据库(NoSql),其灵活的数据存储方式备受当前IT从业人员的青睐。Mongo DB很好的实现了面向对象的思想(OO思想),在Mongo DB中 每一条记录都是一个Document对象。本文介绍了一则生产环境下MongoDB实现分片与集群方案的操作实例。一、 mongodb分片与集群拓扑图二、分片与集群的部署1.Mongodb的安装分别在以上3台服务器安装好mongodb安装方法见安装脚本。2.Mongod 创建单个分片的副本集10.68.4.209建立数据文件夹和日志文件夹mdkir /data/master,slave,arbitermkdir /data/log/mongodb/master,slave,arbiter
