How to install XAMPP & Composer on Linux – Debian

XAMPP by bitnami is a complete stack of Apache, MariaDB(MySql), PHP and Perl. It is a completely free software and widely used on all platforms for web development by developers. Although we have choice to install Apache, MySql and PHP separately on Linux platform easily but many developers choose to install XAMPP for Linux. This article will let you show how to install XAMPP and Composer on Linux – Debian.

XAMPP – Download

Download the latest version of XAMPP from its official website https://www.apachefriends.org by clicking on XAMPP for Linux on home page.

XAMPP – Installation

Open the terminal and navigate to the containing folder using cd command. Possibly your downloaded file will be in Downloads folder.

cd Downloads

Change the permission of file using chmod command. Replace your downloaded filename with xampp-linux-*-installer.run in below command.

sudo chmod 755 xampp-linux-*-installer.run

Execute the file

sudo ./xampp-linux-*-installer.run

You are all set to run XAMPP on your Linux machine.
To start, stop, restart XAMPP run the following commands.

sudo /opt/lampp/lampp start
sudo /opt/lampp/lampp stop
sudo /opt/lampp/lampp restart

Setting up Environment Variables

To install PHP technologies like composer, laravel, codeigniter and many others we need to set-up PHP path as an environment variable. Below are the steps to do this.

Open file /etc/environment as root using an Gedit –

sudo gedit /etc/environment

Add the following line at the end of file and then save and exit –

:/opt/lampp/bin/php

Now we need to create a symbolic link –

sudo ln -s /opt/lampp/bin/php /usr/local/bin/php

Composer – Installation

First we need to download composer using curl. If curl is not installed on your system, first install it using following command –

sudo apt-get install curl

then download composer

curl -sS https://getcomposer.org/installer | php

Now move composer to /usr/local/bin/composer folder using following command –

sudo mv composer.phar /usr/local/bin/composer

Done! All set.

Best Free Vector Graphics Editors for Linux

In Short : List the best vector graphics software for Linux that can be used as an alternative to Adobe Illustrator or CorelDraw for Linux.

A vector graphics editor lets you create and edit vector graphics images, create vector objects and perform all various manipulations to it. Adobe Illustrator and CorelDraw are such premium vector graphics editors, which are used by professionals of print and digital media, but they are not available for Linux flavors.

So what are the available alternatives for Linux? We’ll show you the best available vector graphics software in Linux.

Best free vector graphics editing software for Linux

Installation instructions for Ubuntu / Debian – based Linux distributions is included in this article. But you can easily search the installation instruction for other Linux distribution online. There are a lot of help, support and tutorial articles and videos available online for these softwares.

Inkscape

Inkscape is professional quality vector graphics software which runs on Windows, Mac OS X and GNU/Linux. It is used by design professionals and hobbyists worldwide, for creating a wide variety of graphics such as illustrations, icons, logos, diagrams, maps and web graphics. Inkscape uses the W3C open standard SVG (Scalable Vector Graphics) as its native format, and is free and open-source software.

It is obviously one of the best Linux tools for digital artists around that are actively developed. Inkscape has sophisticated drawing tools with capabilities comparable to Adobe Illustrator, CorelDRAW and Xara Xtreme. It can import and export various file formats, including SVG, AI, EPS, PDF, PS and PNG with a simple interface and options to customize functionalities with add-ons.

Object creation

  • Drawing: pencil tool (freehand drawing with simple paths), pen tool (creating Bézier curves and straight lines), calligraphy tool (freehand drawing using filled paths representing calligraphic strokes)

  • Text tool (multi-line text, full on-canvas editing)
  • Embedded bitmaps (with a command to create and embed bitmaps of selected objects)
  • Clones (“live” linked copies of objects), including a tool to create patterns and arrangements of clones

Object manipulation

  • Transformations (moving, scaling, rotating, skewing), both interactively and by specifying exact numeric values
  • Z-order operations (raising and lowering)
  • Grouping objects (“select in group” without ungrouping, or “enter the group” making it a temporary layer)
  • Layers (lock and/or hide individual layers, rearrange them, etc; layers can form a hierarchical tree)
  • Alignment and distribution commands

Fill and stroke

  • Color selector (RGB, HSL, CMYK, color wheel, CMS)

  • A gradient editor capable of multi-stop gradients
  • Pattern fills (bitmap/vectors)
  • Dashed strokes, with many predefined dash patterns
  •  Path markers (ending, middle and/or beginning marks, e.g. arrowheads)

Operations on paths

  • Node editing: moving nodes and Bezier handles, node alignment and distribution, etc.
  • Converting to path (for text objects or shapes), including converting stroke to path
  • Boolean operations
  • Path simplification, with variable threshold
  • Path insetting and outsetting, including dynamic and linked offset objects
  • Bitmap tracing (both color and monochrome paths)

Text support

  • Multi-line text
  • Uses any installed outline fonts, including right-to-left scripts
  • Kerning, letterspacing, linespacing adjustments
  • Text on path (both text and path remain editable)
  • Text in shape (fill shape following stroke)

Rendering

  • Alpha transparency support for display and PNG export
  • Complete “as you drag” rendering of objects during interactive transformations

File formats
