MongoDB has been widely used as a NoSQL Database in recent years. More and more enterprises are trying to use MongoDB instead of the original Database. MongoDB also performs well in clusters, sharding, and replication. I will introduce various MongoDB deployment experiments.

Preface

As a document-type NoSQL database, MongoDB is very flexible to use, avoiding the Complex Database Design in the early stage of relational databases. MongoDB storage is based on the JSON format and uses Javascript as the database operating language. It gives users unlimited space to imagine and can solve very complex conditional queries on MongoDB servers through programming.

1. Install MongoDB in Windows

Installing MongoDB on a Windows system is very simple. Download the executable Installation File (exe) and double-click to install it. :

Run the command on the MongoDB server:/bin/mongod.exe

Run the command on the MongoDB client:/bin/cmd.exe

2. Install MongoDB in Linux Ubuntu

The Linux system used in this article is Ubuntu 12.04.2 LTS 64bit. you can install the MongoDB database package through apt-get. However, we need to install the official MongoDB software source.

Modify the source. list file of apt and add the 10gen setting.

# Download the key file ~ Sudo apt-key adv -- keyserver hkp: // keyserver.ubuntu.com: 80 -- recv 7F0CEB10Executing: gpg -- ignore-time-conflict -- no-options -- no-default-keyring -- secret-keyring/tmp. kVFab9XYw0 -- trustdb-name/etc/apt/trustdb. gpg -- keyring/etc/apt/trusted. gpg -- primary-keyring/etc/apt/trusted. gpg -- keyserver hkp: // keyserver.ubuntu.com: 80 -- recv 7F0CEB10gpg: Download the key '7f0ceb10' from the hkp server keyserver. ubuntu. comgpg: Key 7F0CEB10: Public Key "Richard Kreuter "Imported gpg: no key that is absolutely trusted is found. gpg: Total number of processes: 1gpg: imported: 1 (RSA: 1) # in source. add MongoDB source configuration in list ~ Echo 'deb dist 10gen '| sudo tee/etc/apt/sources. list. d/mongodb. listdeb dist 10gen # update the software source ~ Sudo apt-get update

Install MongoDB in Linux Ubuntu

# Install the MongoDB Server ~ Sudo apt-get install mongodb-10gen

After the installation is complete, the MongoDB server will automatically start. We check the MongoDB server program.

# Check the system process of the MongoDB server ~ Ps-aux | grep sans MongoDB 6870 3.7 0.4 349208 39740? Ssl/usr/bin/mongod -- config/etc/mongodb. conf # Check the MongoDB server status through the startup command ~ Netstat-nlt | grep 27017tcp00 0.0.0.0: 270170.0.0.0: * LISTEN # Check the MongoDB server status through the startup command ~ Sudo/etc/init. d/mongodb statusRather than invoking init scripts through/etc/init. d, use the service (8) utility, e.g. service mongodb statusSince the script you are attempting to invoke has been converted to anUpstart job, you may also use the status (8) utility, e.g. status mongodbmongodb start/running, process 6870 # Check the MongoDB server status through system services ~ Sudo service mongodb statusmongodb start/running, process 6870

View the status of the MongoDB server on the web console. Enter 28017 in the browser to open the web console.

3. Access MongoDB through the command line Client

After the MongoDB server is installed, the MongoDB command line client program is automatically installed together.

Enter the mongo command on the local machine to start the instance. The client program accesses the MongoDB server.

The MongoDB server allows external access by default. In this way, we have successfully installed MongoDB in Linux Ubuntu.
