首页 / 数据库 / MySQL / MongoDB 副本集+分片 架构部署

Replica Set + Sharding  配置部署

准备工作

架构设计

 需要三台机器（racdb,host8,host9）：
  • 数据节点，sharding2片
  • 每个sharding为Replic Set方式，冗余度为3（主、从、延迟从）
  • mongos（路由节点），数量为3
  • config  server（配置服务器节点），数量为3
  • arbiter server（表决节点），数量为6
 Mongodb ReplicaSET+Sharding架构如下:

安装部署

1.     自动部署脚本

在三个机器分别配置shard1、shard2、arbiter、config server、mongos需要的参数文件 机器1（racdb）# 数据节点mkdir -p /home/mongod/mongodb/shard11cat > /home/mongod/mongodb/shard11/shard11.conf

2. 启动服务

 --在Server1启动shard1、shard2、arbiter1、arbiter2服务# server 1mongod --config /home/mongod/mongodb/shard11/shard11.confmongod --config /home/mongod/mongodb/shard21/shard21.confmongod --config /home/mongod/mongodb/arbiter1/arbiter1.confmongod --config /home/mongod/mongodb/arbiter2/arbiter2.confmongod --config /home/mongod/mongodb/config/config1.conf --在Server2启动shard1、shard2、arbiter1、arbiter2服务# server 2mongod --config /home/mongod/mongodb/shard12/shard12.confmongod --config /home/mongod/mongodb/shard22/shard22.confmongod --config /home/mongod/mongodb/arbiter1/arbiter1.confmongod --config /home/mongod/mongodb/arbiter2/arbiter2.confmongod --config /home/mongod/mongodb/config/config2.conf --在Server3启动shard1、shard2、arbiter1、arbiter2服务# server 3mongod --config /home/mongod/mongodb/shard13/shard13.confmongod --config /home/mongod/mongodb/shard23/shard23.confmongod --config /home/mongod/mongodb/arbiter1/arbiter1.confmongod --config /home/mongod/mongodb/arbiter2/arbiter2.confmongod --config /home/mongod/mongodb/config/config3.conf 然后在server1、server2、server3上分别启动mongos服务# server1mongos --config /home/mongod/mongodb/mongos/mongos1.conf# server2mongos --config /home/mongod/mongodb/mongos/mongos2.conf# server2mongos --config /home/mongod/mongodb/mongos/mongos3.conf更多详情见请继续阅读下一页的精彩内容： http://www.linuxidc.com/Linux/2016-04/130009p2.htm
