MongoDB Quick Start

If you are interested in MongoDb document databases, you need to install them.

Download to the official Windows version of http://www.mongodb.org/display/DOCS/Downloads is currently the latest stable version is 1.2.4. Unzip to f:/sofr/mongodb-win32-i386-1.2.4.

Start mongod

Copy codeThe Code is as follows: F: \ soft \ mongodb-win32-i386-1.2.4> bin \ mongod.exe -- dbpath = f:/mongodb
Mon Mar 08 11:13:17 Mongo DB: starting: pid = 0 port = 27017 dbpath = f:/mongodb master = 0 slave
= 0 32-bit

** NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data
** See http://blog.mongodb.org/post/137788967/32-bit-limitations for more

Mon Mar 08 11:13:18 db version v1.2.4, pdfile version 4.5
Mon Mar 08 11:13:18 git version: 5cf582d3d96b882c400c33e7670b811ccd47f477
Mon Mar 08 11:13:18 sys info: windows (5, 1, 2600, 2, 'service Pack 3') BOOST_LIB_VERSION = 35
Mon Mar 08 11:13:18 waiting for connections on port 27017

-- Dbpath specifies the database directory. The default value is/data/db. win does not have the/data/db directory. Therefore, you cannot start mongod by double-clicking it. The default port is 27017.

In linux, I use legacy-static because the source code compilation fails.

After the server is started, use the client to try it out. It comes with a client (MongoDB shell ). Bin/cmd.exeCopy codeThe Code is as follows: F: \ soft \ mongodb-win32-i386-1.2.4> bin \ cmd.exe
MongoDB shell version: 1.2.4
Url: test
Connecting to: test
Type "exit" to exit
Type "help" for help
> Use test
Switched to db test
> Db. foo. save ({a: 1 })
> Db. foo. find ()
{"_ Id": ObjectId ("4b946bc03f781_1_1542"), "a": 1}
>

Mongod.exe logs can be viewed at the backend.
MongoDB client is rich, I try it with python (see http://api.mongodb.org/python/1.4%2B/installation.html for installation ). Install pymongo

Copy codeThe Code is as follows: easy_install pymongo Copy codeThe Code is as follows: from pymongo import Connection
Connection = Connection ()
Db = connection. test
For f in db. foo. find ():
Print "a = % s, _ id = % s" % (f ['a'], f ['_ id'])

The result is displayed. A = 1.0, _ id = 4b946bc03f781_1542. _ Id is the internal field of mongo.

Its query like SQL is quite attractive ......
