一、目录
1、mongo路径,config数据路径,shard数据路径
2、shard数据路径的结构(共6个分片,分别位于D盘和E盘)
1)D盘中
2)E盘中
3、启动各个服务端的批处理
1)启动configs服务器
mongod --dbpath=d:shard_configs --port 23017
2)启动mongos服务器
mongos --port 25017 --configdb 10.0.0.186:23017
3)启动各个shard分片服务器
mongod --dbpath=d:shard_datashard_data_000 --port 27017
mongod --dbpath=d:shard_datashard_data_001 --port 27018
mongod --dbpath=d:shard_datashard_data_002 --port 27019
mongod --dbpath=e:shard_datashard_data_003 --port 27020
mongod --dbpath=e:shard_datashard_data_004 --port 27021
mongod --dbpath=e:shard_datashard_data_005 --port 27022
二、将各个分片添加到集群中
1、防火墙上开放23017和25017端口
2、将各个分片添加到集群中
C:UsersAdministrator>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>
3、查看最终的分片结果
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>
三、创建数据库和集合,并制定分片键
1、创建数据库,集合,索引
2、指定news,forum集合的分片键
1)数据库web_content启动分片功能
mongos> use admin switched to db admin mongos> db.runCommand({"enablesharding":"web_content"}) { "ok" : 1 } mongos>
2)指定两个集合的分片键
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)查看初始时的分片情况
news集合:
forum集合:
