CentOS Groovy installation tutorial for newbs – CentOS 6.x

CentOS Groovy

CentOS Groovy installation instruction for newbs.

 

Prerequisities

JDK

To install Groovy you have to install the JDK. If you don’t have JDK installed yet follow those instructions by RaveMaker.

 

Groovy Installation

There are several mothods (as always) to install groovy into your CentOS box.

 

Option 1: GVM

The simplest is using the GVM, tool for managing parallel Versions of multiple Software Development Kits on most Unix based systems. It provides a convenient command line interface for installing, switching, removing and listing Candidates.

GVM is a powerful tool to install Candidates and switch between them (on current terminal, or by default). reading the full intro to GVM is recommended.

to install GVM use the command:

curl -s get.gvmtool.net | bash

This will quickly install GVM into your system

gvm-install

Run the following command as required or log again to the system, as GVM is adding this line to your ~/.bash_profile file:

source "/root/.gvm/bin/gvm-init.sh"

which should return nothing. now you are ready to install groovy by:

gvm install groovy
centos groovy install

centos groovy install

Notes:

  • This will installed groovy version 2.2.2. you can use GVM to install specific groovy version, or multiple versions (read the manual).
  • GVM will create the ~/.gvm directory with all the assets inside (~/.gvm/groovy/2.2.2).

that’s it.

 

Option 2: Manual Installation

It’s always recommended to manually install every peace of code to fully understand what going on there. Following the official installation guide,

Download binary

Download binary for groovy from the download page (check if there is newer version, or specific version you need other then 2.3.0-beta-2 shown here):

cd /usr
mkdir groovy
cd groovy
wget http://dl.bintray.com/groovy/maven/groovy-binary-2.3.0-beta-2.zip
unzip groovy-binary-2.3.0-beta-2.zip
rm groovy-binary-2.3.0-beta-2.zip

This will create a /usr/groovy/groovy-2.3.0-beta-2 folder with the files packed inside.

* If you don’t have wget installed use then ‘yum install wget’ command to install it.
* If you don’t have unzip installed use then ‘yum install unzip’ command to install it. 

TIP

Create a symlink to that folder named ‘latest’ which you can change later when you’ll update your groovy installation without the need to update the environment variables.

ln -s groovy-2.3.0-beta-2 ./latest

Set-up environment

Last thing you need is to:

  • set your GROOVY_HOME environment variable to the directory you unpacked the distribution
  • add GROOVY_HOME/bin to your PATH environment variable

Edit your ~/.bash_profile file and append the following lines:

# Groovy
export GROOVY_HOME=/usr/groovy/latest
export PATH=$PATH:$GROOVY_HOME/bin

or, if you didn’t created the latest symlink, use:

# Groovy
export GROOVY_HOME=/usr/groovy/groovy-2.3.0-beta-2
export PATH=$PATH:$GROOVY_HOME/bin

 

Test Groovy

groovy -e ‘println(“Hello, World!”)’

centos groovy

centos groovy

 

And that’s it! You have Groovy Installed.

Cheers!,

    It seems this will also work on Debian based computer. Will try this out as my machine is in Ubuntu, and usually working with Groovy and Grails
