1. 设置Database

sh.enableSharding("database_name");

2. 创建Collection

use database_name

db.createCollection("collection_name");

sh.shardCollection("inv.collection_name",{orderCode:"hashed"});


3. 创建用户（mongos/mongod下都创建）

用户名：username

密码：password

权限：readWrite



db.createUser({user:"user_name",pwd:"password",roles:[{role:"readWrite",db:"database_name"}]})


4. 创建唯一索引

db.inv_record.createIndex({"orderCode": 1,"action": 1},{unique:true});

db.inv_record.createIndex({"createTime": 1,"status": 1 });
