建置流程簡述

1. 建置ConfigService
2. 建置RouteService
3. 新增分片(Mongod)
4. 於Shell下 添加分片至RouteService
5. 開啟分片功能
6. 新增Shard key

此篇文章實作目標 如圖

1.建置 ConfigService

•    1: $mongod --dbpath=C:\ShardDBsForMongoDB\Cofigdata\CofigdataA --port 20000

2.建置RouteService

•    1: mongos --port 3000 --configdb localhost:20000

3.新增分片(Mongod)

• ShardA建置

  •  

       1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardAdata\ShardA1data --port 15000 --replSet shard0/localhost:15001

  •  

       1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardAdata\ShardA2data --port 15001 --replSet shard0/localhost:15000

  • 1: mongos>db.runCommand( 

       2:      { 

       3:      "replSetInitiate": 

       4:          {

       5:          "_id":"shard0","members":

       6:              [

       7:                  {

       8:                  "_id":1,

       9:                  "host":"localhost:15000"

      10:                  },

      11:                  {

      12:                  "_id":2,

      13:                  "host":"localhost:15001"

      14:                  }

      15:              ]

      16:          }

      17:      }

      18: )

• ShardB建置

  •    1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardBdata\ShardB1data --port 16000 --replSet shard1/localhost:16001

  •    1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardBdata\ShardB2data --port 16001 --replSet shard1/localhost:16000

  •    1: mongos>db.runCommand( 

       2:      {  

       3:     "replSetInitiate":  

       4:         { 

       5:         "_id":"shard1","members": 

       6:             [ 

       7:                 {

       8:                 "_id":1, 

       9:                 "host":"localhost:16000" 

      10:                 }, 

      11:                 { 

      12:                 "_id":2, 

      13:                 "host":"localhost:16001" 

      14:                 } 

      15:             ] 

      16:         }

      17:      }

      18: )

• ShardC建置

  •  1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardCdata\ShardC1data --port 18000 --replSet shard2/localhost:18001

  •  1: $mongod.exe --dbpath C:\ShardDBsForMongoDB\ShardCdata\ShardC2data --port 18001 --replSet shard2/localhost:18000

  •    1: mongos>db.runCommand( 

       2:     { 

       3:     "replSetInitiate": 

       4:          {

       5:          "_id":"shard2","members":

       6:              [

       7:                 {

       8:                 "_id":1,

       9:                 "host":"localhost:18000"

      10:                  },

      11:                 {

      12:                 "_id":2,

      13:                 "host":"localhost:18001"

      14:                 }

      15:              ]

      16:          }

      17:       }

      18: )

4.於Shell下 添加分片至RouteService

• 連線至Mongos

     1: $mongo --port 3000
• 添加分片

     1: mongos> db.runCommand({addshard:'shard0/localhost:15000',allowLocal:true})

     2: mongos> db.runCommand({addshard:'shard1/localhost:16000',allowLocal:true})

     3: mongos> db.runCommand({addshard:'shard2/localhost:18000',allowLocal:true})

5.開啟分片功能

•    1: mongos>db.runCommand({"enablesharding":"wfm"})

6.新增Shard key

•   1: db.runCommand( { shardCollection: "wfm.VoiceRecords", key: { CreatAt:1,Site:1 } } ) 

7.檢驗Shard 是否已被建立

•    1: mongos> use config

•    1: mongos>db.shards.find()

• 由下圖可看到Shard0，Shard1，Shard2 已被加入該config內。
