以下是MongoDB分片集群搭建的步骤： 1.启动config server ```shell mongod --configsvr --replSet configReplSet --dbpath /data/configdb --port 27019 ``` 2.初始化config server副本集 ```shell mongo --port 27019 config = { "_id" : "configReplSet", "members" : [ { "_id" : 0, "host" : "localhost:27019" } ] } rs.initiate(config) ``` 3.启动mongos ```shell mongos --configdb configReplSet/localhost:27019 --port 27017 ``` 4.启动shard1 ```shell mongod --shardsvr --replSet shard1ReplSet --dbpath /data/shard1 --port 27018 ``` 5.初始化shard1副本集 ```shell mongo --port 27018 config = { "_id" : "shard1ReplSet", "members" : [ { "_id" : 0, "host" : "localhost:27018" } ] } rs.initiate(config) ``` 6.启动shard2 ```shell mongod --shardsvr --replSet shard2ReplSet --dbpath /data/shard2 --port 27019 ``` 7.初始化shard2副本集 ```shell mongo --port 27019 config = { "_id" : "shard2ReplSet", "members" : [ { "_id" : 0, "host" : "localhost:27019" } ] } rs.initiate(config) ``` 8.将shard1和shard2添加到mongos中 ```shell mongo --port 27017 sh.addShard("shard1ReplSet/localhost:27018") sh.addShard("shard2ReplSet/localhost:27019") ``` 9.创建分片的数据库和集合 ```shell use test sh.enableSharding("test") db.createCollection("testCollection") sh.shardCollection("test.testCollection", {"_id": "hashed"}) ```
