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.
