如何在CentOS 7服务器上安装NodeJS

Introduction

Node.js is a Javascript platform for server-side programming. It

allows users to easily create networked applications that require

backend functionality. By using Javascript as both the client and server

language, development can be fast and consistent.

In this guide, we will show you a few different ways of getting

Node.js installed on a CentOS 7 server so that you can get started. Most

users will want to use the EPEL installation instructions or the NVM

installation steps.

Install Node from Source

One way of acquiring Node.js is to obtain the source code and compile it yourself.

To do so, you should grab the source code from the project’s website.

On the downloads page, right click on the “Source Code” link and click

“Copy link address” or whatever similar option your browser gives you.

On your server, use wget and paste the link that you copied in order to download the archive file:

wget

Extract the archive and move into the new directory by typing:

tar xzvf node-v* cd node-v*

There are a few packages that we need to download from the CentOS

repositories in order to compile the code. Use yum to get these now:

sudo yum install gcc gcc-c++

Now, we can configure and compile the software:

./configure

make

The compilation will take quite awhile. When it is finished, you can install the software onto your system by typing:

sudo make install

To check that the installation was successful, you can ask Node to display its version number:

node –version

v0.10.30

If you see the version number, then the installation was completed successfully.

Install a Package from the Node Site

Another option for installing Node.js on your server is to simply get

the pre-built packages from the Node.js website and install them.

You can find the Linux binary packages here. Since CentOS 7 only

comes in the 64-bit architecture, right click on the link under “Linux

Binaries (.tar.gz)” labeled “64-bit”. Select “Copy link address” or

whatever similar option your browser provides.

On your server, change to your home directory and use the wget

utility to download the files. Paste the URL you just copied as the

argument for the command:

cd ~

wget

Note: Your version number in the URL is likely to be different than

the one above. Use the address you copied from the Node.js site rather

than the specific URL provided in this guide.

Next, we will extract the binary package into our system’s local

package hierarchy with the tar command. The archive is packaged within a

versioned directory, which we can get rid of by passing the

–strip-components 1 option. We will specify the target directory of our

command with the -C command:

sudo tar –strip-components 1 -xzvf node-v* -C /usr/local

This will install all of the components within the /usr/local branch of your system.

You can verify that the installation was successful by asking Node for its version number:

node –version

v0.10.30

The installation was successful and you can now begin using Node.js on your CentOS 7 server.

Install Node from the EPEL Repository

An alternative installation method uses the EPEL (Extra Packages for

Enterprise Linux) repository that is available for CentOS and related

distributions.

To gain access to the EPEL repo, you must modify the repo-list of

your installation. Fortunately, we can reconfigure access to this

repository by installing a package available in our current repos called

epel-release.

sudo yum install epel-release

Now that you have access to the EPEL repository, you can install Node.js using your regular yum commands:

sudo yum install nodejs

Once again, you can check that the installation was successful by asking Node to return its version number:

node –version

v0.10.30

Many people will also want access to npm to manage their Node packages. You can also get this from EPEL by typing:

sudo yum install npm

Install Node Using the Node Version Manager

Another way of installing Node.js that is particularly flexible is

through NVM, the Node version manager. This piece of software allows you

to install and maintain many different independent versions of Node.js,

and their associated Node packages, at the same time.

To install NVM on your CentOS 7 machine, visit the project’s GitHub

page. Copy the curl or wget command from the README file that displays

on the main page. This will point you towards the most recent version of

the installation script.

Before piping the command through to bash, it is always a good idea

to audit the script to make sure it isn’t doing anything you don’t agree

with. You can do that by removing the | bash segment at the end of the

curl command:

curl https//raw.githubusercontent.com/creationix/nvm/v0.13.1/install.sh

Take a look and make sure you are comfortable with the changes it is

making. When you are satisfied, run the command again with | bash

appended at the end. The URL you use will change depending on the latest

version of NVM, but as of right now, the script can be downloaded and

executed by typing:

curl | bash

This will install the nvm script to your user account. To use it, you must first source your .bash_profile:

source ~/.bash_profile

Now, you can ask NVM which versions of Node it knows about:

nvm list-remote

. . .

v0.10.29

v0.10.30

v0.11.0

v0.11.1

v0.11.2

v0.11.3

v0.11.4

v0.11.5

v0.11.6

v0.11.7

v0.11.8

v0.11.9

v0.11.10

v0.11.11

v0.11.12

v0.11.13

You can install a version of Node by typing any of the releases you see. For instance, to get version 0.10.30, you can type:

nvm install v0.10.30

You can see the different versions you have installed by typing:

nvm list

- v0.10.30

system

You can switch between them by typing:

nvm use v0.10.30

Now using node v0.10.30

To set this version as the default, type:

nvm alias default v0.10.30

default - v0.10.30

You can verify that the install was successful using the same technique from the other sections, by typing:

node –version

v0.10.30

From the version number output, we can tell that Node is installed on our machine as we expected.

Conclusion

As you can see, there are quite a few different ways of getting

Node.js up and running on your CentOS 7 server. If one of the

installation methods is giving you problems, try one of the other

options.

如何在centos下部署Node环境

你可以通过运行以下命令。 sudo yum install epel-release现在可以使用yum命令安装Node.js了。 sudo yum install nodejs因为在开发过程中我需要管理节点包,我还要安装新公共管理的软件包管理器,使用以下命令。 sudo yum install npm

node.js怎么安装node modules

1、首先,在CentOS上使用命令yum install nodejs可以直接安装,但是这样可能无法安装最新版本。

2、安装好之后,可以使用node -v命令和npm -v命令查看Node.js的版本和包管理器的版本。

3、接着可以使用yum uninstall nodejs卸载旧版本的nodejs。同时也会自动卸载npm。

4、接着,再次使用yum install命令安装nodejs,这时候安装的就是新版本了。

5、安装完毕后,使用npm -v查看包管理器版本,也是新版本。

6、如果只是要运行node.js,直接node回车即可。在里边输入javascript代码。

如何在CentOS / RHEL 7/6/5上安装最新的Nodejs和NPM

1、如果对nodejs环境有比较高的要求,建议选择源码安装的方式进行安装。

你可以到nodejs org官网上面找到相对的tar.gz文件包。

通过wget命令下载到centos服务器上, 然后进行源码安装。

2、如果对版本要求不高,可以直接用centos的包管理器yum进行安装

yum install nodejs npm

3、nodejs版本也可以通过nvm等工具去控制,期待深入研究。
