{

? ? ? ? "info" : "Config now saved locally. ?Should come online in about a minute.",

? ? ? ? "ok" : 1

}

八、添加分片

在三个节点上任一个节点都可以操作

192.168.1.30

[root@orcl sd3]# mongo --port 27017

MongoDB shell version: 2.6.4

connecting to: 127.0.0.1:27017/test

mongos> use admin

switched to db admin

mongos> db.runCommand({addshard:"set1/192.168.1.30:27018,192.168.1.52:27018,192.168.1.108:27018"})

{ "shardAdded" : "set1", "ok" : 1 }

mongos> db.runCommand({addshard:"set2/192.168.1.30:27019,192.168.1.52:27019,192.168.1.108:27019"})

{ "shardAdded" : "set2", "ok" : 1 }

mongos> db.runCommand({addshard:"set3/192.168.1.30:27020,192.168.1.52:27020,192.168.1.108:27020"})

{ "shardAdded" : "set3", "ok" : 1 }

九、查看分片信息

mongos> db.runCommand({listshards : 1})

{

? ? ? ? "shards" : [

? ? ? ? ? ? ? ? {

? ? ? ? ? ? ? ? ? ? ? ? "_id" : "set1",

? ? ? ? ? ? ? ? ? ? ? ? "host" : "set1/192.168.1.30:27018,192.168.1.52:27018"

? ? ? ? ? ? ? ? },

? ? ? ? ? ? ? ? {

? ? ? ? ? ? ? ? ? ? ? ? "_id" : "set2",

? ? ? ? ? ? ? ? ? ? ? ? "host" : "set2/192.168.1.108:27019,192.168.1.52:27019"

? ? ? ? ? ? ? ? },

? ? ? ? ? ? ? ? {

? ? ? ? ? ? ? ? ? ? ? ? "_id" : "set3",

? ? ? ? ? ? ? ? ? ? ? ? "host" : "set3/192.168.1.108:27020,192.168.1.30:27020"

? ? ? ? ? ? ? ? }

? ? ? ? ],

? ? ? ? "ok" : 1

}

十、删除分片

mongos> db.runCommand({removeshard:"set3"})

{

? ? ? ? "msg" : "draining started successfully",

? ? ? ? "state" : "started",

? ? ? ? "shard" : "set3",

? ? ? ? "ok" : 1

}

十一、管理分片

mongos> use config

switched to db config

mongos> db.shards.find();

{ "_id" : "set1", "host" : "set1/192.168.1.30:27018,192.168.1.52:27018" }

{ "_id" : "set2", "host" : "set2/192.168.1.108:27019,192.168.1.52:27019" }

{ "_id" : "set3", "host" : "set3/192.168.1.108:27020,192.168.1.30:27020" }

十二、对要分片的库和表声明

切换到admin库

mongos> use admin ? ? ?

声明test库允许分片

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

{ "ok" : 1 }?

声明users表要分片 ?

mongos> db.runCommand({shardcollection:"test.lineqi",key:{id:"hashed"}})

{ "collectionsharded" : "test.lineqi", "ok" : 1 }

十???、测试脚本

切换到test

mongos>use test

mongos> for (var i = 1; i <= 100000; i++) db.lineqi.save({id:i,name:"12345678",sex:"male",age:27,value:"test"});?

WriteResult({ "nInserted" : 1 })

十四、测试结果

查看分片信息

mongos> use config

switched to db config

mongos> db.chunks.find();

{ "_id" : "test.users-id_MinKey", "lastmod" : Timestamp(2, 0), "lastmodEpoch" : ObjectId("55ddb3a70f613da70e8ce303"), "ns" : "test.users", "min" : { "id" : { "$minKey" : 1 } }, "max" : { "id" : 1 }, "shard" : "set1" }

{ "_id" : "test.users-id_1.0", "lastmod" : Timestamp(3, 1), "lastmodEpoch" : ObjectId("55ddb3a70f613da70e8ce303"), "ns" : "test.users", "min" : { "id" : 1 }, "max" : { "id" : 4752 }, "shard" : "set2" }

{ "_id" : "test.users-id_4752.0", "lastmod" : Timestamp(3, 0), "lastmodEpoch" : ObjectId("55ddb3a70f613da70e8ce303"), "ns" : "test.users", "min" : { "id" : 4752 }, "max" : { "id" : { "$maxKey" : 1 } }, "shard" : "set3" }

{ "_id" : "test.lineqi-id_MinKey", "lastmod" : Timestamp(3, 2), "lastmodEpoch" : ObjectId("55ddb7460f613da70e8ce380"), "ns" : "test.lineqi", "min" : { "id" : { "$minKey" : 1 } }, "max" : { "id" : NumberLong("-6148914691236517204") }, "shard" : "set2" }

{ "_id" : "test.lineqi-id_-3074457345618258602", "lastmod" : Timestamp(3, 4), "lastmodEpoch" : ObjectId("55ddb7460f613da70e8ce380"), "ns" : "test.lineqi", "min" : { "id" : NumberLong("-3074457345618258602") }, "max" : { "id" : NumberLong(0) }, "shard" : "set3" }
