本文详细介绍了如何在特定IP地址布局下规划并实施MongoDB的分片集群与复制集环境，包括目录创建、节点启动、复制集配置及路由服务器设置等关键步骤。

mongodb分片+复制集环境规划：

192.168.0.105、
192.168.0.106、
192.168.0.107、
192.168.0.108、

192.168.0.105 mongod shard1_1 40000 (rs0-primayr)
mongod shard2_3 40005 (rs2-arbiter)
mongod config1 50000
192.168.0.106 mongod shard1_2 40001 (rs0-secondary)
mongod config2 50000
mongod mongos1 60000
192.168.0.107 mongod shard2_1 40003 (rs1-primayr)
mongod shard1_3 40002 (rs0-arbiter)
mongod mongos2 60000
192.168.0.108 mongod shard2_2 40004 (rs1-secondary)
mongod config3 50000
mongod mongos3 60000

192.168.0.105上创建目录：
mkdir -p /appl/data/shard1_1
mkdir -p /appl/data/shard1_1/log
mkdir -p /appl/data/shard2_3
mkdir -p /appl/data/shard2_3/log
mkdir -p /appl/data/config1
mkdir -p /appl/data/config1/log

192.168.0.106上创建目录：
mkdir -p /appl/data/shard1_2
mkdir -p /appl/data/shard1_2/log
mkdir -p /appl/data/config2
mkdir -p /appl/data/config2/log
mkdir -p /appl/data/mongos

192.168.0.107上创建目录：
mkdir -p /appl/data/shard2_1
mkdir -p /appl/data/shard2_1/log
mkdir -p /appl/data/shard1_3
mkdir -p /appl/data/shard1_3/log
mkdir -p /appl/data/mongos

192.168.0.108上创建目录：
mkdir -p /appl/data/shard2_2
mkdir -p /appl/data/shard2_2/log
mkdir -p /appl/data/config3
mkdir -p /appl/data/config3/log
mkdir -p /appl/data/mongos

配置 Shard Cluster

连接到其中一台机器的端口 60000 的 mongos 进程，并切换到 admin 数据库做以下配置
db.runCommand({addshard:"rs0/192.168.0.105:40000,192.168.0.106:40001,192.168.0.107:40002"});
db.runCommand({addshard:"rs1/192.168.0.107:40003,192.168.0.108:40004,192.168.0.105:40005"});
