The deployment of the MongoDB environment is simple. People who have already used it will certainly share the same idea with me. First download the corresponding version ( on the official website, to distinguish whether your own is 32-bit or 64-bit.
MongoDB version. The even version is the stable version and the odd version is the development version. For example, stable version (1.2.0, 1.2.1, 1.2.2, etc.) is started with 1.2, and development version (1.3.0, 1.3.1, 1.3.2, etc.) Starting with 1.3 ).

My local development environment is win7 (32bit, dual-core), the company's development environment centos (a Linux version, 64bit, 4 CPUs)


In Windows

1: Decompress the downloaded compressed file. (I am on E: \ nosql \ MongoDB)
2: create a directory to store database files. The default value is/data/DB/(c: \ data \ dB in Windows ).
3: Go to the MongoDB decompressed directory (I am in E: \ nosql \ MongoDB ),
> Cd E: \ nosql \ MongoDB \ bin
> Mongod help can view some MongoDB parameters. Below are the three common parameters I listed: DB storage path, log storage path, and log storage method.

-- Dbpath Arg directory for datafiles
-- Logpath Arg log file to send write to instead of stdout-has to be
A file, not directory

-- Logappend append to logpath instead of over-Writing

> Mongod -- dbpath E: \ nosql \ MongoDB \ data -- logpath = E: \ nosql \ MongoDB \ log \ MongoDB. log -- logappend
All output going to: e: \ nosql \ MongoDB \ log \ MongoDB. log will be displayed in the CMD window.

Enter http: // localhost: 27017/in the browser and you will see the following prompt:
You are trying to access MongoDB on the native driver port. For HTTP diagnostic access, add 1000 to the port number

In this way, the MongoDB Database Service has been successfully started.

Enter http: // localhost: 28017/in the browser, which is a monitoring interface of the MongoDB system. If you specify the -- Port port number, you must use a port number greater than 1000 to access MongoDB.
Monitoring Interface.

4: open another cmd window and start a MongoDB client.
> Cd E: \ nosql \ MongoDB \ bin
> Mongo
MongoDB shell version: 1.8.3-RC0
Connecting to: Test

> Show DBS // view the system database. These are my local DBS.

Deploy MongoDB in centos. I connected to the company's centos server through securecrt. It has the same deployment operations on Windows.
Download the corresponding official version and decompress it to the corresponding directory. My directory is/root/soft, listing extracted files

[Root @ app-vwsc-01 soft] # ls
Mongodb-linux-x86_64-1.8.2 mongodb-linux-x86_64-1.8.2.tar nagios-nrpe_2.8.1.tar.gz nagios-plugins-1.4.15 nagios-plugins-1.4.15.tar.gz
[Root @ app-vwsc-01 soft] # cd mongodb-linux-x86_64-1.8.2/bin
[Root @ app-vwsc-01 bin] # ls
Bsondump Mongo mongod mongodump unzip Export Program Files submit import mongorestore mongos unzip sniff unzip stat
[Root @ app-vwsc-01 bin] #. /mongod -- dbpath/root/mongodbpro/data/DB -- logpath/root/mongodbpro/data/log/MongoDB. log -- logappend // start the mongod Server
All output going to:/root/mongodbpro/data/log/MongoDB. Log // at this time, the MongoDB service has been started.

Start a MongoDB Client
[Root @ app-vwsc-01 bin] #./Mongo
MongoDB shell version: 1.8.2
Connecting to: Test
> Show DBS // view the current database


Currently, all the deployment has been completed on win7 and centos, but pay attention to the following points:

1: After we start the MongoDB service, all MongoDB logs are written to the MongoDB. Log File in win7. (This file is customized by me)
** Note: When Using MongoDB 32 bit, you are limited to about 2 gigabytes of data
** See
** With -- dur, the limit is lower

In the above warning, it means that in 32-Bit mode, MongoDB can only process 2 GB of data, because I use 32-bit MongoDB and MongoDB uses the memory-mapped file storage engine, if a stable version is used on a 64-bit machine, this warning will not be returned.

We need to develop the habit of viewing logs, which is useful for MongoDB monitoring.

2: Disable the MongoDB service. This method is provided first and will be mentioned later.

Switched to DB Admin
> DB. shutdownserver () // execute shutdownserver ()

2: Start the CMD window in win7. I suggest using Windows powershell, which is much better than the CMD window.
3: I add "// explanation" after some commands. This is not a command and serves only as one of my explanations.
4: In the next section, I will talk about the basic operations of MongoDB and the selection of the C # driver. I hope you can help me with the problem of writing.
