MongoDB部署架构之优先方案.doc

2011/9/16 制作人：酷酷 /lidaohangMongo之架构部署(Replica Sets+Sharding)1、 环境要构建一个 MongoDB Sharding Cluster，需要三种角色：Shard Server: mongod 实例，用于存储实际的数据块。Config Server: mongod 实例，存储了整个 Cluster Metadata，其中包括 chunk 信息。Route Server: mongos 实例，前端路由，客户端由此接入，且让整个集群看上去像单一进程 数据库。03070809Shard1Shard2Shard3Shard1Shard2 Shard1Shard2Shard3Shard3 Shard3Shard1Shard21. 节点： S1: 03,07,09,08(arbiter) S2: 07,03,08,09(arbiter)

重命名mongodb-linux-x86_64-2.0.0.tgz为mongodb mv mongodb-linux-x86_64-2.0.0 mongodb4. 进入mongodb目录 cd mongodb5. 新建文件夹data mkdir data配置Replica Sets,Config Server031. 创建相应的文件夹(注意此处的testadmin是客户端登陆名)mkdir -p
