資料複製集rs0:

mongodb0.example.net:26001
mongodb1.example.net:26002
mongodb2.example.net:26003

資料複製集rs1:

mongodb3.example.net:26004
mongodb4.example.net:26005
mongodb5.example.net:26006

配置伺服器複製集configReplSet:

mongodb6.example.net:26007
mongodb7.example.net:26008
mongodb8.example.net:26009

mongos例項:

mongodb9.example.net:26010

步驟：

1、更新hosts檔案 (測試時,xxx.xxx.xxx.xxx 可以為同一IP)

路徑：C:\Windows\System32\drivers\etc

在hosts檔案裡新增：

xxx.xxx.xxx.xxx    mongodb0.example.net
xxx.xxx.xxx.xxx    mongodb1.example.net
xxx.xxx.xxx.xxx    mongodb2.example.net
xxx.xxx.xxx.xxx    mongodb3.example.net
xxx.xxx.xxx.xxx    mongodb4.example.net
xxx.xxx.xxx.xxx    mongodb5.example.net
xxx.xxx.xxx.xxx    mongodb6.example.net
xxx.xxx.xxx.xxx    mongodb7.example.net
xxx.xxx.xxx.xxx    mongodb8.example.net
xxx.xxx.xxx.xxx    mongodb9.example.net

2、新增資料夾

路徑：D:\MongoDB\data

新增10個資料夾db26001，db26002，db26003 ...db26010

3、準備config檔案

路徑：D:\MongoDB\Server\3.4\bin

檔名：mongodb26001.conf (屬於複製集rs0)

port=26001
logpath=D:\MongoDB\data\db26001\mongod26001.log
logappend=true
pidfilepath=D:\MongoDB\data\db26001\26001.pid  
dbpath=D:\MongoDB\data\db26001
bind_ip=mongodb0.example.net

,127.0.0.1
maxConns=500
replSet=rs0
shardsvr=true
#auth=true
#keyFile=D:\MongoDB\Server\3.2\bin\aaakeyfile1.dat
#fork=true
#cpu=true
#noauth=true

//mongodb26002.conf,mongodb26003.conf修改紅色字型配置

檔名：mongodb26004.conf (屬於複製集rs1)

port=26004
logpath=D:\MongoDB\data\db26004\mongod26004.log
logappend=true
pidfilepath=D:\MongoDB\data\db26004\26004.pid  
dbpath=D:\MongoDB\data\db26004
bind_ip=mongodb3.example.net,127.0.0.1
maxConns=500
replSet=rs1
shardsvr=true
#auth=true
#keyFile=D:\MongoDB\Server\3.2\bin\aaakeyfile1.dat
#fork=true
#cpu=true
#noauth=true

//mongodb26005.conf,mongodb26006.conf修改紅色字型配置

檔名：mongodb26007.conf (屬於配置伺服器複製集configReplSet)
port=26007
logpath=D:\MongoDB\data\db26007\mongod26007.log
logappend=true
pidfilepath=D:\MongoDB\data\db26007\26007.pid  
dbpath=D:\MongoDB\data\db26007
bind_ip=mongodb6.example.net,127.0.0.1
maxConns=500
replSet=configReplSet
configsvr=true
#auth=true
#keyFile=D:\MongoDB\Server\3.2\bin\aaakeyfile1.dat
#fork=true
#cpu=true
#noauth=true


//mongodb26008.conf,mongodb26009.conf修改紅色字型配置

檔名：mongodb26010.conf (屬於mongos例項)

port=26010
logpath=D:\MongoDB\data\db26010\mongod26010.log
logappend=true
pidfilepath=D:\MongoDB\data\db26010\26010.pid  
#dbpath=D:\MongoDB\data\db26010
bind_ip=mongodb9.example.net,127.0.0.1
maxConns=500
configdb=configReplSet/mongodb6.example.net:26007,mongodb7.example.net:26008,mongodb8.example.net:26009
#auth=true
#keyFile=D:\MongoDB\Server\3.2\bin\aaakeyfile1.dat
#fork=true
#cpu=true
#noauth=true

4、配置複製集rs0,rs1

詳細步驟：http://blog.csdn.net/albert0707/article/details/53992932

5、進入複製集rs0主節點批量加入資料

mongo mongodb0.example.net:26001

use test
var bulk = db.test_collection.initializeUnorderedBulkOp();
people = ["Marc", "Bill", "George", "Eliot", "Matt", "Trey", "Tracy", "Greg", "Steve", "Kristina", "Katie", "Jeff"];
for(var i=0; i<1000000; i++){
   user_id = i;
   name = people[Math.floor(Math.random()*people.length)];
   number = Math.floor(Math.random()*10001);
   bulk.insert( { "user_id":user_id, "name":name, "number":number });
}
bulk.execute();

6、配置Config Server 複製集configReplSet

mongod -f D:\MongoDB\Server\3.4\bin\mongodb26007.conf

rs.initiate({
   _id: "configReplSet",
   configsvr: true,
   members: [
      { _id: 0, host: "mongodb6.example.net:26007" },
      { _id: 1, host: "mongodb7.example.net:26008" },
      { _id: 2, host: "mongodb8.example.net:26009" }
   ]
})

rs.conf()

7、啟動mongos例項

mongos -f D:\MongoDB\Server\3.4\bin\mongodb26010.conf

進入mongos例項

mongo mongodb9.example.net:26010

新增分片,新增索引,集合名稱：test_collection , 片鍵為number

sh.addShard( "rs0/mongodb0.example.net:26001,mongodb1.example.net:26002,mongodb2.example.net:26003" )
sh.addShard( "rs1/mongodb3.example.net:26004,mongodb4.example.net:26005,mongodb5.example.net:26006" )
sh.enableSharding( "test" )

use test

db.test_collection.createIndex( { number : 1 } )

sh.shardCollection( "test.test_collection", { "number" : 1 } )

8、檢驗結果

use test

db.stats()
db.printShardingStatus()

Run these commands for a second time to demonstrate that chunks are migrating from rs0 to rs1.
