基本环境:
由于资源紧张,只有3台虚拟机的关系,只做两个replicaSet,每台机器配置分别如下:
10.10.1.55这台机器安装 Primary1,configServer1, Arbiter1
10.10.1.56 安装 Primary2,configServer2, Arbiter2
10.10.1.57 安装 Secondary1,Secondary2,configServer3,mongos
1.55机器的配置文件如下:

分别通过mongod --config filename 来启动不同的mongo 进程,成功启动后可以通过netstat 查看在1.55 机器上分别分配了Primary1端口:40000,Arbiter1端口:40002,configureServer1端口:40006

分别通过mongod --config filename 来启动不同的mongo 进程,成功启动后可以通过netstat 查看在1.55 机器上分别分配了rs0_secondary1端口:40001,rs1_secondary1端口:40004,configureServer3端口:40008,mongos路由端口:40009
现在用mongo shell登录primary1 配置replicaSet0,步骤如下:
cfg={ "_id" : "rs0", "members" : [ { "_id" : 0, "host" : "10.10.1.55:40000" }, { "_id" : 1, "host" : "10.10.1.57:40001" } ] }
rs.initiate(cfg)
rs.status()
rs.addArb("10.10.1.55:40002")
现在用mongo shell登录primary2 配置replicaSet1,步骤如下:
cfg={ "_id" : "rs1", "members" : [ { "_id" : 0, "host" : "10.10.1.56:40003" }, { "_id" : 1, "host" : "10.10.1.57:40004" } ] }
rs.initiate(cfg)
rs.status()
rs.addArb("10.10.1.56:40005")
使用mongo shell登录mongos路由添加分片信息:

现在创建一个新的数据库来测试一下分片:
mongos> use people
switched to db people
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"jordan"+i,country:"American"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"gaga"+i,country:"American"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"ham"+i,country:"UK"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"brown"+i,country:"UK"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"ramda"+i,country:"Malaysia"})
WriteResult({ "nInserted" : 1 })
开始建立分片:

},

}
mongos> sh.shardCollection(

,{country:1,_id:1})
{

现在由于数据量不多只有一个分片在rs0上,可以通过增加数据量来提高分片:
1
2
|
for
(var i=10;i<10000;i++) db.customers.insert({name:
"ham"
+i,country:
"UK"
})
for
(var i=10;i<10000;i++) db.customers.insert({name:
"ramda"
+i,country:
"Malaysia"
})

mongos> sh.status()

people.customers
shard key: { "country" : 1, "_id" : 1 }

rs1 2
rs0 1
{ "country" : { "$minKey" : 1 }, "_id" : { "$minKey" : 1 } } -->> { "country" : "American", "_id" : ObjectId("561c7da73af7c7865defefb1") } on : rs1 Timestamp(2, 0)

现在rs0上有一个分片,rs1上有两个分片
