How to Setup Node.JS on Ubuntu 15.04 with Different Methods
|
||||
================================================================================
|
||||
This is such an important article to guide you about the installation and setup of Node.js on Ubuntu 15.04. Node.js is basically a server side java script programming to provide you bindings for enabling the input and output socket bios and streams. It has a high through put and non-blocking IO in a single threaded event loop. It’s also a platform layer that provides the functionality to interact with the Operating system to write file, read files and to do networking operations. So in this article we will perform different installation methods to setup Node.Js on Ubuntu 15.04 server.
|
||||
|
||||
### Methods to Install Node.JS ###
|
||||
|
||||
Their are different ways to install Node.Js and we can prefer to choose any one. Following are some important ways to install Node.Js that we will use to guide you about their each setup on Ubuntu 15.04 so make sure to remove the previous previous packages to avoid from any package conflict.
|
||||
|
||||
- Installation of Node.JS from Source Code
|
||||
- Installation of Node.JS from Package Manager
|
||||
- Installation of Node.JS from Github Repository
|
||||
- Installation of Node.JS with NVM
|
||||
|
||||
### 1) Installing from Source Code ###
|
||||
|
||||
Let's start with installation of Node.JS from the Source Code, so make sure that your system is up to date and dependent packages are pre installed. So follow the below steps and start the setup.
|
||||
|
||||
#### STEP 1: System Update ####
|
||||
|
||||
Use following commands and update Operating system and ten install the required packages are necessary for Node.JS setup.
|
||||
|
||||
root@ubuntu-15:~# apt-get update
|
||||
|
||||
root@ubuntu-15:~# apt-get install python gcc make g++
|
||||
|
||||
#### STEP 2: Get Source Code of Node.JS ####
|
||||
|
||||
After we had installed the dependent packages now from the official web link of Node.JS just download its source code package and extract it as in following commands.
|
||||
|
||||
root@ubuntu-15:~# wget http://nodejs.org/dist/v0.12.4/node-v0.12.4.tar.gz
|
||||
root@ubuntu-15:~# tar zxvf node-v0.12.4.tar.gz
|
||||
|
||||
#### STEP 3: Starting Installation ####
|
||||
|
||||
Now move to the source code directory and execute the .configuration file
|
||||
|
||||
|
||||
|
||||
root@ubuntu-15:~# ls
|
||||
node-v0.12.4 node-v0.12.4.tar.gz
|
||||
root@ubuntu-15:~# cd node-v0.12.4/
|
||||
root@ubuntu-15:~/node-v0.12.4# ./configure
|
||||
root@ubuntu-15:~/node-v0.12.4# make install
|
||||
|
||||
### Testing after Installation of Node.Js from Source Code ###
|
||||
|
||||
Once the installation is done after running make installa command, we check its version and test that Node.Js is working fine by executing some test out puts.
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# node -v
|
||||
v0.12.4
|
||||
|
||||
|
||||
|
||||
Create a new file with .js extension execute it with Node command.
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# touch helo_test.js
|
||||
root@ubuntu-15:~/node-v0.12.4# vim helo_test.js
|
||||
console.log('Hello World');
|
||||
|
||||
Now execute it with Node command.
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# node helo_test.js
|
||||
Hello World
|
||||
|
||||
The out put shows that we had successfully installed Node.JS on Ubuntu 15.04 which is now ready to create applications on it using java scripts.
|
||||
|
||||
### 2) Installing from Package Manager ###
|
||||
|
||||
The installation of Node.JS through Package Manager is also a very simple process to setup on Ubuntu through NodeSource by adding its Personal Package Archives (PPA).
|
||||
|
||||
We will go through the following steps to install Node.JS through PPA.
|
||||
|
||||
#### STEP 1: Get the Source Code using Curl ####
|
||||
|
||||
Before getting the source code by using the Curl command we must update our system and then run the curl command to fetch the NodeSource into local repository.
|
||||
|
||||
root@ubuntu-15:~#apt-get update
|
||||
root@ubuntu-15:~# curl -sL https://deb.nodesource.com/setup | sudo bash -
|
||||
|
||||
The curl will execute the following tasks.
|
||||
|
||||
## Installing the NodeSource Node.js 0.10 repo...
|
||||
## Populating apt-get cache...
|
||||
## Confirming "vivid" is supported...
|
||||
## Adding the NodeSource signing key to your keyring...
|
||||
## Creating apt sources list file for the NodeSource Node.js 0.10 repo...
|
||||
## Running `apt-get update` for you...
|
||||
Fetched 6,411 B in 5s (1,077 B/s)
|
||||
Reading package lists... Done
|
||||
## Run `apt-get install nodejs` (as root) to install Node.js 0.10 and npm
|
||||
|
||||
#### STEP 2: Installation of NodeJS and NPM ####
|
||||
|
||||
As per the output of Curl we had fetched the NodeSource to our local repository now through apt-get commands we will install the NodeJS and NPM packages.
|
||||
|
||||
root@ubuntu-15:~# apt-get install nodejs
|
||||
|
||||
|
||||
|
||||
#### STEP 3: Installing Build Essentials Tool ####
|
||||
|
||||
To compile and install native addons from npm we may also need to install build tools using following command as.
|
||||
|
||||
root@ubuntu-15:~# apt-get install -y build-essential
|
||||
|
||||
### Testing With Node.JS Shell ###
|
||||
|
||||
Testing of Node.Js is similar to the one that we did after installation from the source Code.
|
||||
so lets start with the node command as follow and get its output result to see if Node.JS is fully functional.
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> console.log('Node.js Installed Using Package Manager');
|
||||
Node.js Installed Using Package Manager
|
||||
|
||||
----------
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> a = [1,2,3,4,5]
|
||||
[ 1, 2, 3, 4, 5 ]
|
||||
> typeof a
|
||||
'object'
|
||||
> 5 + 2
|
||||

|
||||
### REPL For Your NodeJS Apps ###
|
||||
|
||||
REPL is the Node.js shell, any valid Javascript which can be written in a script can be passed to the REPL. So lets see how REPL works with NodeJS.
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> var repl = require("repl");
|
||||
undefined
|
||||
> repl.start("> ");
|
||||
|
||||
Press Enter and it will show out put like this:
|
||||
> { domain: null,
|
||||
_events: {},
|
||||
_maxListeners: 10,
|
||||
useGlobal: false,
|
||||
ignoreUndefined: false,
|
||||
eval: [Function],
|
||||
inputStream:
|
||||
{ _connecting: false,
|
||||
_handle:
|
||||
{ fd: 0,
|
||||
writeQueueSize: 0,
|
||||
owner: [Circular],
|
||||
onread: [Function: onread],
|
||||
reading: true },
|
||||
_readableState:
|
||||
{ highWaterMark: 0,
|
||||
buffer: [],
|
||||
length: 0,
|
||||
pipes: null,
|
||||
...
|
||||
...
|
||||
|
||||
Here is the list of command line help that we can use to work with REPL.
|
||||
|
||||
|
||||
|
||||
### Working with NodeJS Packet Manager ###
|
||||
|
||||
NPM is simple CLI tool for ensuring that a given node script runs continuously. It helps to Install and manage dependencies through the file package.json. We will start its using init command as.
|
||||
|
||||
root@ubuntu-15:~# npm init
|
||||
|
||||
|
||||
|
||||
### 3) Installing from Github Repository ###
|
||||
|
||||
In this method to install Node.JS we will consider few simple steps to directory clone the Node.JS repository from the github.
|
||||
|
||||
Before the start of configurations through the the cloned package of Node.JS make sure that we must have following dependent packages installed with us.
|
||||
|
||||
root@ubuntu-15:~# apt-get install g++ curl make libssl-dev apache2-utils git-core
|
||||
|
||||
Now start the clone with git command and change the directory to its configuration file.
|
||||
|
||||
root@ubuntu-15:~# git clone git://github.com/ry/node.git
|
||||
root@ubuntu-15:~# cd node/
|
||||
|
||||
|
||||
|
||||
To install from the cloned repository now lets run the .config command and then make install to complete the setup of Node.Js .
|
||||
|
||||
root@ubuntu-15:~# ./configure
|
||||
|
||||
|
||||
|
||||
Run the make install command that will takes few minutes so be patient and get it ready finalize the setup on Node.JS package for you.
|
||||
|
||||
root@ubuntu-15:~/node# make install
|
||||
|
||||
root@ubuntu-15:~/node# node -v
|
||||
v0.13.0-pre
|
||||
|
||||
### Testing with Node.JS ###
|
||||
|
||||
root@ubuntu-15:~/node# node
|
||||
> a = [1,2,3,4,5,6,7]
|
||||
[ 1, 2, 3, 4, 5, 6, 7 ]
|
||||
> typeof a
|
||||
'object'
|
||||
> 6 + 5
|
||||
11
|
||||
>
|
||||
(^C again to quit)
|
||||
>
|
||||
root@ubuntu-15:~/node#
|
||||
|
||||
### 4) Installing Node.JS Using Node Version Manager ###
|
||||
|
||||
In this last method we show you we can easily install Node.JS with NVM method. This is one of the best method to install and configure Node.JS it provides us with facility to control versions.
|
||||
|
||||
So before starting with this method make sure that the previously installed package is not already present there if you are working on the same machine.
|
||||
|
||||
#### STEP 1: Installing Prerequisites ####
|
||||
|
||||
Let's start with the system update and then install the following prerequisites for the Ubuntu Server to setup Node.JS using NodeJS Versions Manager System. Using the Curl command we will get NVM from the git to our local repository.
|
||||
|
||||
root@ubuntu-15:~# apt-get install build-essential libssl-dev
|
||||
root@ubuntu-15:~# curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh
|
||||
|
||||
|
||||
|
||||
#### STEP 2: Update Home Environment ####
|
||||
|
||||
After the curl command downloads the necessary packages for the NVM in the home directory of the user it also make changes to the bash profile. so in order to update those change and get access to NVM we must relogin to the terminal or we can update it using the source command as below.
|
||||
|
||||
root@ubuntu-15:~# source ~/.profile
|
||||
|
||||
Now we can use the NVM to choose the default NVM version or by moving to the previous version of NVM that we can do so by using the following commands.
|
||||
|
||||
root@ubuntu-15:~# nvm ls
|
||||
root@ubuntu-15:~# nvm alias default 0.12.4
|
||||
|
||||
|
||||
|
||||
#### STEP 3: Using NodeJS Versions Manager ####
|
||||
|
||||
We have successfully setup the NodeJS with NVM package and now can use it with its useful commands.
|
||||
|
||||
|
||||
|
||||
### CONCLUSION ###
|
||||
|
||||
Now we are ready to go with building server side applications with Node.JS and you are free to choose the best installation setup of your choice as we had done with four optional installations of Node.Js on the latest version of Ubuntu 15.04 with priority installation sequence, now its up to you to follow the one of your own choice and start coding with NodeJS.

在Ubuntu下用不同方式安装Node.JS
|
||||
================================================================================
|
||||
|
||||
如果你要在Ubuntu 15.04上安装Node.js的话，这篇教程对你来说肯定很重要。Node.js根本上来说就是一个运行在服务端上的封装好了输入输出流的javascript程序。Node.js巧妙的使用单线程的event loop来处理异步IO。同时它在平台层面上，面向系统拥有非常实用的文件读写，网络操作功能。所以这篇文章将展示在Ubuntu 15.04 server上不同的安装Node.Js的方式。
|
||||
|
||||
### 安装Node.JS 的方法###
|
||||
|
||||
有许多不同的方法安装Node.JS，我们可以选择其一。通过本篇文章我们将手把手带着你在Ubuntu 15.04上安装Node.Js，在此之前请卸载旧版本的包以免发生包冲突。
|
||||
|
||||
- 从源代码安装Node.JS
|
||||
- 用包管理器安装Node.JS
|
||||
- 从Github远程库安装Node.JS
|
||||
- 用NVM安装Node.JS
|
||||
|
||||
### 1) 从源代码安装Node.JS ###
|
||||
|
||||
让我们开始从从源代码安装Node.JS之前，请确认系统上的所有的依赖包都已经更新到最新版本。然后跟着以下步骤来开始安装：
|
||||
|
||||
#### 步骤1: 升级系统 ####
|
||||
|
||||
用以下命令来升级系统，并且安装一些Node.JS必要的包。
|
||||
|
||||
root@ubuntu-15:~# apt-get update
|
||||
|
||||
root@ubuntu-15:~# apt-get install python gcc make g++
|
||||
|
||||
#### 步骤2: 获取Node.JS的源代码 ####
|
||||
|
||||
安装好依赖包之后我们可以从官方网站上下载Node.JS的源代码。下载以及解压的命令如下：
|
||||
|
||||
root@ubuntu-15:~# wget http://nodejs.org/dist/v0.12.4/node-v0.12.4.tar.gz
|
||||
root@ubuntu-15:~# tar zxvf node-v0.12.4.tar.gz
|
||||
|
||||
#### 步骤3: 开始安装 ####
|
||||
|
||||
现在我们进入源代码的目录然后运行.configuration文件
|
||||
|
||||
|
||||
|
||||
root@ubuntu-15:~# ls
|
||||
node-v0.12.4 node-v0.12.4.tar.gz
|
||||
root@ubuntu-15:~# cd node-v0.12.4/
|
||||
root@ubuntu-15:~/node-v0.12.4# ./configure
|
||||
root@ubuntu-15:~/node-v0.12.4# make install
|
||||
|
||||
### 安装后测试 ###
|
||||
|
||||
只要运行一次上面的命令就顺利安装好了Node.JS，现在我们来确认一下版本信息和测试以下Node.JS是否可以运行输出。
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# node -v
|
||||
v0.12.4
|
||||
|
||||
|
||||
|
||||
创建一个以.js为扩展名的文件然后用Node的命令运行
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# touch helo_test.js
|
||||
root@ubuntu-15:~/node-v0.12.4# vim helo_test.js
|
||||
console.log('Hello World');
|
||||
|
||||
现在我们用Node的命令运行文件
|
||||
|
||||
root@ubuntu-15:~/node-v0.12.4# node helo_test.js
|
||||
Hello World
|
||||
|
||||
输出的结果证明我们已经成功的在Ubuntu 15.04安装好了Node.JS，同时我们也能运行JavaScript文件。
|
||||
|
||||
### 2) 利用包管理器安装Node.JS ###
|
||||
|
||||
在Ubuntu下用包管理器安装Node.JS是非常简单的，只要增加NodeSource的个人软件包档案（PPA）即可。
|
||||
|
||||
我们将下面通过PPA安装Node.JS
|
||||
|
||||
#### 步骤1: 用curl获取源代码 ####
|
||||
|
||||
在我们用curl获取源代码之前，我们必须先升级操作系统然后用curl命令获取NodeSource添加到本地仓库。
|
||||
|
||||
root@ubuntu-15:~#apt-get update
|
||||
root@ubuntu-15:~# curl -sL https://deb.nodesource.com/setup | sudo bash -
|
||||
|
||||
curl将运行以下任务
|
||||
|
||||
## Installing the NodeSource Node.js 0.10 repo...
|
||||
## Populating apt-get cache...
|
||||
## Confirming "vivid" is supported...
|
||||
## Adding the NodeSource signing key to your keyring...
|
||||
## Creating apt sources list file for the NodeSource Node.js 0.10 repo...
|
||||
## Running `apt-get update` for you...
|
||||
Fetched 6,411 B in 5s (1,077 B/s)
|
||||
Reading package lists... Done
|
||||
## Run `apt-get install nodejs` (as root) to install Node.js 0.10 and npm
|
||||
|
||||
#### 步骤2: 安装NodeJS和NPM ####
|
||||
|
||||
运行以上命令之后如果输出如上所示，我们可以用apt-get命令来安装NodeJS和NPM包。
|
||||
|
||||
root@ubuntu-15:~# apt-get install nodejs
|
||||
|
||||
|
||||
|
||||
#### STEP 3: Installing Build Essentials Tool ####
|
||||
#### 步骤3: 安装一些必备的工具 ####
|
||||
|
||||
通过以下命令来安装编译安装一些我们必需的本地插件。
|
||||
|
||||
root@ubuntu-15:~# apt-get install -y build-essential
|
||||
|
||||
### 通过Node.JS Shell来测试 ###
|
||||
|
||||
测试Node.JS的步骤与之前使用源代码安装相似，通过以下node命令来确认Node.JS是否完全安装好:
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> console.log('Node.js Installed Using Package Manager');
|
||||
Node.js Installed Using Package Manager
|
||||
|
||||
----------
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> a = [1,2,3,4,5]
|
||||
[ 1, 2, 3, 4, 5 ]
|
||||
> typeof a
|
||||
'object'
|
||||
> 5 + 2
|
||||
7
|
||||
>
|
||||
(^C again to quit)
|
||||

|
||||
root@ubuntu-15:~#
|
||||
|
||||
### 使用NodeJS应用进行简单的测试 ###
|
||||
|
||||
REPL是一个Node.js的shell，任何有效的JavaScript代码都能在REPL下运行通过。所以让我们看看在Node.JS下的REPL是什么样子吧。
|
||||
|
||||
root@ubuntu-15:~# node
|
||||
> var repl = require("repl");
|
||||
undefined
|
||||
> repl.start("> ");
|
||||
|
||||
Press Enter and it will show out put like this:
|
||||
> { domain: null,
|
||||
_events: {},
|
||||
_maxListeners: 10,
|
||||
useGlobal: false,
|
||||
ignoreUndefined: false,
|
||||
eval: [Function],
|
||||
inputStream:
|
||||
{ _connecting: false,
|
||||
_handle:
|
||||
{ fd: 0,
|
||||
writeQueueSize: 0,
|
||||
owner: [Circular],
|
||||
onread: [Function: onread],
|
||||
reading: true },
|
||||
_readableState:
|
||||
{ highWaterMark: 0,
|
||||
buffer: [],
|
||||
length: 0,
|
||||
pipes: null,
|
||||
...
|
||||
...
|
||||
|
||||
以下是可以在REPL下使用的命令列表
|
||||
|
||||
|
||||
|
||||
### 使用NodeJS的包管理器 ###
|
||||
|
||||
NPM是一个提供给node脚本连续运行的命令行工具，它能通过package.json来安装和管理依赖包。最开始从初始化命令init开始
|
||||
|
||||
root@ubuntu-15:~# npm init
|
||||
|
||||
|
||||
|
||||
### 3) 从Github远程库安装Node.JS ###
|
||||
|
||||
在这个方法中我们需要一些步骤来把Node.JS从Github的远程的仓库克隆到本地仓库目录
|
||||
|
||||
在开始克隆（clone）包到本地并且配制之前，我们要先安装以下依赖包
|
||||
|
||||
root@ubuntu-15:~# apt-get install g++ curl make libssl-dev apache2-utils git-core
|
||||
|
||||
现在我们开始用git命令克隆到本地并且转到配制目录
|
||||
|
||||
root@ubuntu-15:~# git clone git://github.com/ry/node.git
|
||||
root@ubuntu-15:~# cd node/
|
||||
|
||||
|
||||
|
||||
clone仓库之后，通过运行.config命令来编译生成完整的安装包。
|
||||
|
||||
root@ubuntu-15:~# ./configure
|
||||
|
||||
|
||||
|
||||
运行make install命令之后耐心等待几分钟，程序将会安装好Node.JS
|
||||
|
||||
root@ubuntu-15:~/node# make install
|
||||
|
||||
root@ubuntu-15:~/node# node -v
|
||||
v0.13.0-pre
|
||||
|
||||
### 测试Node.JS ###
|
||||
|
||||
root@ubuntu-15:~/node# node

### 4) 通过NVM安装Node.JS ###
|
||||
|
||||
在最后一种方法中我们我们将用NVM来比较容易安装Node.JS。安装和配制Node.JS，这是最好的方法之一，它可以供我们选择要安装的版本。
|
||||
|
||||
在安装之前，请确认本机以前的安装包已经被卸载
|
||||
|
||||
#### 步骤1: 安装依赖包 ####
|
||||
|
||||
首先升级Ubuntu Server系统，然后安装以下安装Node.JS和使用NVM所要依赖的包。用curl命令从git上下载NVM到本地仓库：
|
||||
|
||||
root@ubuntu-15:~# apt-get install build-essential libssl-dev
|
||||
root@ubuntu-15:~# curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh
|
||||
|
||||
|
||||
|
||||
#### 步骤2: 修改Home环境 ####
|
||||
|
||||
用curl从NVM下载必需的包到用户的home目录之后，我们需要修改bash的配制文件添加NVM，之后只要重新登录中断或者用如下命令更新即可
|
||||
|
||||
root@ubuntu-15:~# source ~/.profile
|
||||
|
||||
现在我们可以用NVM来设置默认的NVM的版本或者用如下命令来指定之前版本：
|
||||
|
||||
root@ubuntu-15:~# nvm ls
|
||||
root@ubuntu-15:~# nvm alias default 0.12.4
|
||||
|
||||
|
||||
|
||||
#### 步骤3: 使用NVM ####
|
||||
|
||||
我们已经通过NVM成功的安装了Node.JS，所以我们现在可以使用各种有用的命令。
|
||||
|
||||
|
||||
|
||||
### 总结 ###
|
||||
|
||||
现在我们已经准备好了在服务端安装Node.JS，你可以从我们说的四种方式中选择最合适你的方式在最新的Ubuntu 15.04上来安装Node.JS，安装好之后你就可以利用Node.JS来编写你的代码。
