1、目錄web
一、mongo路徑,config數據路徑,shard數據路徑shell
二、shard數據路徑的結構(共6個分片,分別位於D盤和E盤)數據庫
1)D盤中服務器
2)E盤中url
三、啓動各個服務端的批處理spa
1)啓動configs服務器code
mongod --dbpath=d:\shard_configs --port 23017
2)啓動mongos服務器blog
mongos --port 25017 --configdb 10.0.0.186:23017
3)啓動各個shard分片服務器索引
mongod --dbpath=d:\shard_data\shard_data_000 --port 27017
mongod --dbpath=d:\shard_data\shard_data_001 --port 27018
mongod --dbpath=d:\shard_data\shard_data_002 --port 27019
mongod --dbpath=e:\shard_data\shard_data_003 --port 27020
mongod --dbpath=e:\shard_data\shard_data_004 --port 27021
mongod --dbpath=e:\shard_data\shard_data_005 --port 27022
2、將各個分片添加到集羣中md5
一、防火牆上開放23017和25017端口
二、將各個分片添加到集羣中
C:\Users\Administrator>mongo 10.0.0.186:25017 MongoDB shell version: 2.4.5 connecting to: 10.0.0.186:25017/test mongos> use admin switched to db admin mongos> db.runCommand({addshard:"10.0.0.186:27017",allowLocal:true}) { "shardAdded" : "shard0000", "ok" : 1 } mongos> db.runCommand({addshard:"10.0.0.186:27018",allowLocal:true}) { "shardAdded" : "shard0001", "ok" : 1 } mongos> db.runCommand({addshard:"10.0.0.186:27019",allowLocal:true}) { "shardAdded" : "shard0002", "ok" : 1 } mongos> db.runCommand({addshard:"10.0.0.186:27020",allowLocal:true}) { "shardAdded" : "shard0003", "ok" : 1 } mongos> db.runCommand({addshard:"10.0.0.186:27021",allowLocal:true}) { "shardAdded" : "shard0004", "ok" : 1 } mongos> db.runCommand({addshard:"10.0.0.186:27022",allowLocal:true}) { "shardAdded" : "shard0005", "ok" : 1 } mongos>
三、查看最終的分片結果
mongos> use config switched to db config mongos> db.shards.find() { "_id" : "shard0000", "host" : "10.0.0.186:27017" } { "_id" : "shard0001", "host" : "10.0.0.186:27018" } { "_id" : "shard0002", "host" : "10.0.0.186:27019" } { "_id" : "shard0003", "host" : "10.0.0.186:27020" } { "_id" : "shard0004", "host" : "10.0.0.186:27021" } { "_id" : "shard0005", "host" : "10.0.0.186:27022" } mongos>
3、建立數據庫和集合,並制定分片鍵
一、建立數據庫,集合,索引
二、指定news,forum集合的分片鍵
1)數據庫web_content啓動分片功能
mongos> use admin switched to db admin mongos> db.runCommand({"enablesharding":"web_content"}) { "ok" : 1 } mongos>
2)指定兩個集合的分片鍵
mongos> use admin switched to db admin mongos> db.runCommand({"shardcollection":"web_content.news","key":{"url_md5":1}} ) { "collectionsharded" : "web_content.news", "ok" : 1 } mongos> db.runCommand({"shardcollection":"web_content.forum","key":{"url_md5":1} }) { "collectionsharded" : "web_content.forum", "ok" : 1 } mongos>
3)查看初始時的分片狀況
news集合:
forum集合:
