我的mongodb安装在[d:\Java\mongodb]

所以需要根目录手动创建文件夹【e:\data\db】

mongodb使用服务方式安装

 'D:\Java\mongodb\bin\mongod.exe --bind_ip 127.0.0.1 --logpath d:\\Java\\mongodb
\\logs\\MongoLog.log --logappend --dbpath d:\\data --directoryperdb --service'
Fri Jan 10 09:17:45.050 Service can be started from the command line with 'net s
tart MongoDB'

日志需要指定具体的文件，比如MongoLog.log 之前没有置顶就报错【服务没有及时响应或控制请求】

安装、删除服务指令

mongod --install

mongod --service

mongod --remove

mongod --reinstall

或者

C:\mongodb\bin\mongod.exe --remove

启动服务

net start Mongodb

停止服务

net stop Mongodb

测试简单JavaScript语句

> 3+3
6

> db
test
> // the first write will create the db:

> db.foo.insert( { a : 1 } )
> db.foo.find()
{ _id : ..., a : 1 }
mongo.exe的详细的用法可以参考mongo.exe --help

下面从官网摘抄下来的普通sql跟MongoDB的区别

Create and Alter

The following table presents the various SQL statements related totable-level actions and the corresponding MongoDB statements.

SQL Schema Statements	MongoDB Schema Statements	Reference
CREATE TABLE users ( id MEDIUMINT NOT NULL AUTO_INCREMENT, user_id Varchar(30), age Number, status char(1), PRIMARY KEY (id) )	Implicitly created on first insert() operation. The primary key_idis automatically added if_id field is not specified. db.users.insert( { user_id: "abc123", age: 55, status: "A" } ) However, you can also explicitly create a collection: db.createCollection("users")	Seeinsert() anddb.createCollection()for more information.
ALTER TABLE users ADD join_date DATETIME	Collections do not describe or enforce the structure of itsdocuments; i.e. there is no structural alteration at thecollection level. However, at the document level, update() operations can add fields to existingdocuments using the$set operator. db.users.update( { }, { $set: { join_date: new Date() } }, { multi: true } )	See the Data Modeling Concepts, update(), and$set for moreinformation on changing the structure of documents in acollection.
ALTER TABLE users DROP COLUMN join_date	Collections do not describe or enforce the structure of itsdocuments; i.e. there is no structural alteration at the collectionlevel. However, at the document level, update() operations can remove fields fromdocuments using the$unset operator. db.users.update( { }, { $unset: { join_date: "" } }, { multi: true } )	See Data Modeling Concepts, update(), and$unset for more information on changing the structure ofdocuments in a collection.
CREATE INDEX idx_user_id_asc ON users(user_id)	db.users.ensureIndex( { user_id: 1 } )	See ensureIndex()andindexes for more information.
CREATE INDEX idx_user_id_asc_age_desc ON users(user_id, age DESC)	db.users.ensureIndex( { user_id: 1, age: -1 } )	See ensureIndex()andindexes for more information.
DROP TABLE users	db.users.drop()	See drop() formore information.

Insert

The following table presents the various SQL statements related toinserting records into tables and the corresponding MongoDB statements.

SQL INSERT Statements	MongoDB insert() Statements	Reference
INSERT INTO users(user_id, age, status) VALUES ("bcd001", 45, "A")	db.users.insert( { user_id: "bcd001", age: 45, status: "A" } )	See insert() for more information.

Select

The following table presents the various SQL statements related toreading records from tables and the corresponding MongoDB statements.

SQL SELECT Statements	MongoDB find() Statements	Reference

SELECT id, user_id, status FROM users	db.users.find( { }, { user_id: 1, status: 1 } )	See find()for more information.
SELECT user_id, status FROM users	db.users.find( { }, { user_id: 1, status: 1, _id: 0 } )	See find()for more information.
SELECT * FROM users WHERE status = "A"	db.users.find( { status: "A" } )	See find()for more information.
SELECT user_id, status FROM users WHERE status = "A"	db.users.find( { status: "A" }, { user_id: 1, status: 1, _id: 0 } )	See find()for more information.
SELECT * FROM users WHERE status != "A"	db.users.find( { status: { $ne: "A" } } )	See find()and$ne for more information.
SELECT * FROM users WHERE status = "A" AND age = 50	db.users.find( { status: "A", age: 50 } )	See find()and$and for more information.
SELECT * FROM users WHERE status = "A" OR age = 50	db.users.find( { $or: [ { status: "A" } , { age: 50 } ] } )	See find()and$or for more information.
SELECT * FROM users WHERE age > 25	db.users.find( { age: { $gt: 25 } } )	See find()and$gt for more information.
SELECT * FROM users WHERE age < 25	db.users.find( { age: { $lt: 25 } } )	See find()and$lt for more information.
SELECT * FROM users WHERE age > 25 AND age <= 50	db.users.find( { age: { $gt: 25, $lte: 50 } } )	See find(),$gt, and $lte formore information.
SELECT * FROM users WHERE user_id like "%bc%"	db.users.find( { user_id: /bc/ } )	See find()and$regex for more information.
