Nodejs+express4.0+mongodb installation method for Linux, Mac

No more nonsense.

1: Download the Nodejs package

as follows: http://www.nodejs.org/download/

Download source code version needs to be extracted to its directory execution./configure, then make && make install;

and binaries tar.gz after decompression can.

2: Download MongoDB

as follows: Http://www.mongodb.org/downloads

and binaries tar.gz after decompression can.

3: Configure Environment variables

CD ~; This directory has a. Bash_profile edit it

Export node_home= $HOME/(Node_path); export mongodb_home= $HOME/(mongodb_path); Export PATH = $PATH: $NODE _home/bin:$ Mongodb_home/bin;export node_path= $NODE _home/lib/node_modules: $PATH;

(node_path) node unzipped directory, (mongodb_path) MongoDB unzipped directory

Then execute node-v,npm-v and mongo-version to determine if the configuration environment is successful. Success will see the version number.

4: Install express4.x

And then execute

Express Ejs NodeTest

Go to nodetest directory execution

NPM INSTALLNPM Start

This launches a service

You can access the http://127.0.0.1:3000 in this server's browser

5:mongodb Server

Start the MongoDB server first

Mongod--dbpath= (Mongodb_path)/db

(Mongodb_path) you want to store the DB directory, as long as you have access to any place.

After execution, you can execute the database operation with a command by executing MONGO.

Specific Nodejs access to MONGODB operations.

var Mongodb = require ("MongoDB"),      Db = mongodb.db,      Connection = mongodb.connection,      Server = Mongodb.server var mongo = new Db ("TestDb", New Server ("localhost", connection.default_port), {safe:true}), Mongo.open (function (Err, db) {   db.collection ("test_table", function (err,collection) {      collection.save ({name: ' Test '},{safe:true}, function (Err,app) {         mongo.close ();         Console.log (app);});})

Finally configure the domain name of Nodejs

Otherwise, it's always ip:port access too cumbersome.

An example of Nginx server

Just configure the vhost below it to create a domain name you name can be

Example: vhost/sys.test.com.conf

server{   Listen;   server_name sys.test.com.conf;   Location/{      proxy_pass http://127.0.0.1:3000;   }}

Ok. Rest ..... Take a break ....
