搭建Mongodb集群：分片Sharding+副本集Replica Set

架构图如下：
客户请求： client
   路由：Mongs1 Mongs2 Mongs3
        40000  40100  402000
   配置：        config1     config2   config3
        config:30000 30100 30200
   副本集：
        rs1:  27017 27117 27217
        rs2:  27018 27118 27218
        rs3:  27019 27119 27219

添加windows服务形式启动：
rs1:
sc.exe create MongoDB0 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb0.cfg\"" DisplayName= "MongoDB0" start= "auto"
sc.exe create MongoDB1 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb1.cfg\"" DisplayName= "MongoDB1" start= "auto"
sc.exe create MongoDB2 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb2.cfg\"" DisplayName= "MongoDB2" start= "auto"
sc.exe create config1 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\config1.cfg\"" DisplayName= "config1" start= "auto"


rs2:
sc.exe create MongoDB3 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb3.cfg\"" DisplayName= "MongoDB3" start= "auto"
sc.exe create MongoDB4 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb4.cfg\"" DisplayName= "MongoDB4" start= "auto"
sc.exe create MongoDB5 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb5.cfg\"" DisplayName= "MongoDB5" start= "auto"
sc.exe create config2 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\config2.cfg\"" DisplayName= "config2" start= "auto"


rs3:
sc.exe create MongoDB6 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb6.cfg\"" DisplayName= "MongoDB6" start= "auto"
sc.exe create MongoDB7 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb7.cfg\"" DisplayName= "MongoDB7" start= "auto"
sc.exe create MongoDB8 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\mongodb8.cfg\"" DisplayName= "MongoDB8" start= "auto"
sc.exe create config3 binPath= "\"D:\mongodb\bin\mongod.exe\" --service --config=\"D:\mongodb\db\config3.cfg\"" DisplayName= "config3" start= "auto"


net start MongoDB0
net start MongoDB1
net start MongoDB2
net start MongoDB3
net start MongoDB4
net start MongoDB5
net start MongoDB6
net start MongoDB7
net start MongoDB8
net start config1
net start config2
net start config3

配置分片：
 
mongo -port 27017
config = {_id:'rs1',members:[
{_id:0,host:'10.16.122.15:27017'},
{_id:1,host:'10.16.122.15:27117'},
{_id:2,host:'10.16.122.15:27217',arbiterOnly:true}
]};

rs.initiate(config)
rs.status()

mongo -port 27018
config = {_id:'rs2',members:[
{_id:0,host:'10.16.122.15:27018'},
{_id:1,host:'10.16.122.15:27118'},
{_id:2,host:'10.16.122.15:27218',arbiterOnly:true}
]};

rs.initiate(config)
rs.status()
   
mongo -port 27019
config = {_id:'rs3',members:[
{_id:0,host:'10.16.122.15:27019'},
{_id:1,host:'10.16.122.15:27119'},
{_id:2,host:'10.16.122.15:27219',arbiterOnly:true}
]};

rs.initiate(config)
rs.status()

配置路由：

mongs: 40000 40100 40200

sc.exe create mongs1 binPath= "\"D:\mongodb\bin\mongos.exe\" --service --config=\"D:\mongodb\db\mongs1.cfg\"" DisplayName= "mongs1" start= "auto"
sc.exe create mongs2 binPath= "\"D:\mongodb\bin\mongos.exe\" --service --config=\"D:\mongodb\db\mongs2.cfg\"" DisplayName= "mongs2" start= "auto"
sc.exe create mongs3 binPath= "\"D:\mongodb\bin\mongos.exe\" --service --config=\"D:\mongodb\db\mongs3.cfg\"" DisplayName= "mongs3" start= "auto"

net start mongs1
net start mongs2
net start mongs3

添加分片
1连接任意一台，其他无需这样操作：
/usr/local/mongodb/bin/mongo --port 40000
use admin
db.runCommand({addshard:'rs1/10.16.122.15:27017,10.16.122.15:27117,10.16.122.15:27217'})
db.runCommand({addshard:'rs2/10.16.122.15:27018,10.16.122.15:27118,10.16.122.15:27218'})
db.runCommand({addshard:'rs3/10.16.122.15:27019,10.16.122.15:27119,10.16.122.15:27219'})

db.runCommand({ listshards:1 })

通过执行以下命令，可以让数据库跨shard，如果不执行这步，数据库只会存放在一个shard，
一旦激活数据库分片，数据库中不同的collection将被存放在不同的shard上，
但一个collection仍旧存放在同一个shard上，要使单个collection也分片，
还需单独对collection作些操作
db.runCommand({enablesharding:"test"});

要使单个collection也分片存储，需要给collection指定一个分片key，通过以下命令操作
db.runCommand( { shardcollection : "test.c1",key : {id: 1},unique : true } )

use test

for(var i=1;i<=2000003;i++)  db.c1.save({id:i,value1:"1234567890",value2:"1234567890",value3:"1234567890",value4:"1234567890"});
