IntelliJ IDEA

INSTALLATION INSTRUCTIONS

===============================================================================

  Linux Installation Instructions

  ------------------------------------------------------------------------------   1. Unpack the IntelliJ IDEA distribution archive that you downloaded to      where you wish to install the program. We will refer to this destination      location as your {installation home} below.

  2. Open a console and cd into "{installation home}/bin" and type:

       ./idea.sh

     to start the application. As a side effect, this will initialize various

     configuration files in the ~/.IdeaIC2016.3 directory.

  3. [OPTIONAL] Add "{installation home}/bin" to your PATH environment

     variable so that you may start IntelliJ IDEA from any directory.

  4. [OPTIONAL] To adjust the value of the JVM heap size, create

      ~/.IdeaIC2016.3/idea.vmoptions (or idea64.vmoptions       if using a 64-bit JDK), and set the -Xms and -Xmx parameters. To see how       to do this, you can reference the vmoptions file under       "{installation home}/bin" as a model.

  [OPTIONAL] Changing the location of "config" and "system" directories

  ------------------------------------------------------------------------------   By default, IntelliJ IDEA stores all your settings under the ~/.IdeaIC2016.3/config   directory and uses ~/.IdeaIC2016.3/system as a data cache.   If you want to change these settings,

  1. Open a console and cd into ~/.IdeaIC2016.3/

  2. Create the file "idea.properties" and open it in an editor. Set the

     idea.system.path and/or idea.config.path variables as desired, for      example:

     idea.system.path=~/custom/system

     idea.config.path=~/custom/config

  3. Note that we recommend to store data cache ("system" directory) on a disk

     with at least 1GB of free space.

Enjoy!
