#Config Server

在Server 192.168.100.208、192.168.100.209、192.168.100.210上执行:

mongod --configsvr --dbpath=/usr/local/mongo/conf --port 20000 --logpath=/usr/local/mongo/log/config.log --logappend --fork

#配置3 台Route Process

在Server 192.168.100.208、192.168.100.209、192.168.100.210上执行:

mongos --configdb 192.168.100.208:20000,192.168.100.209:20000,192.168.100.210:20000 --port 30000 --chunkSize 1 --logpath=/usr/local/mongo/log/mongos.log --logappend

--fork

配置Shard Cluster

连接到其中一台机器的端口30000 的mongos 进程，并切换到admin 数据库做以下配置

mongo admin --port 30000

MongoDB shell version: 2.2.0

connecting to: 127.0.0.1:30000/admin

mongos> db.runCommand({addshard:"shard1/192.168.100.208:27017,192.168.100.209:27017,192.168.100.210:27017"});db.runCommand({addshard:"shard1/192.168.100.208:27017,192.168.100.209:27017,192.168.100.210:27017"});

{ "shardAdded" : "shard1", "ok" : 1 }

mongos> db.runCommand({addshard:"shard2/192.168.100.208:27018,192.168.100.209:27018,192.168.100.210:27018"});db.runCommand({addshard:"shard2/192.168.100.208:27018,192.168.100.209:27018,192.168.100.210:27018"});

{ "shardAdded" : "shard2", "ok" : 1 }

激活数据库及集合的分片

mongos> db.runCommand({ enablesharding:"hong" })

{ "ok" : 1 }

mongos> db.runCommand({ shardcollection: "hong.users", key: { _id:1 }})

{ "collectionsharded" : "andylhz.users", "ok" : 1 }

插入测试数据

use andylhz

for(var i=1;i<=2000000;i++) db.users.insert({id:i,addr_1:"Beijing",addr_2:"Shanghai"});
