    This blog will help you to understand how to install node.js

    Install Node.js

    First update the apt-get package lists with this command:

    $ sudo apt-get update

    Now install the git package using apt-get

    $ sudo apt-get install git

    Please change your home directory now and download the source for Node,js with wget command. Paste this link which will be going to download node.js for you.

    $ cd ~
    $ wget https://nodejs.org/dist/v4.2.3/node-v4.2.3-linux-x64.tar.gz

    Now make the new directory node and extract the tar archive it with the following commands:

    $ mkdir node
    $ tar xvf node-v*.tar.?z --strip-components=1 -C ./node

    Since we no longer needed Node.js archive that you have just downloaded it, change your home directory and use this command rm to delete Node.js archive:

    $ cd ~
    $ rm -rf node-v*

    Next, we'll configure the global prefix of npm, where npm will create symbolic links to installed Node packages, to somewhere that it's in your default path. We'll set it to /usr/local with this command:

    $ mkdir node/etc
    $ echo 'prefix=/usr/local' > node/etc/npmrc

    Now move the node and npm binaries to installation location via this command:

    $ sudo mv node /opt/

    Now change the owner of files to root:

    $ sudo chown -R root: /opt/node

    Now in your default path, create symbolic links of the node and npm binaries:

    $ sudo ln -s /opt/node/bin/node /usr/local/bin/node
    $ sudo ln -s /opt/node/bin/npm /usr/local/bin/npm

    Node.js is installed successfully. To check it please run this command:

    $ node -v

    All done!. 

    Thanks for reading the blog
