CentOS Grails installation tutorial for newbs – CentOS 6.x

centos grails

centos grails installation tutorial for newbs. for CentOS 6.x (And probably for older/later)



You have to install Groovy (which require JDK). If you don’t have Groovy (And JDK) installed follow those instructions.

  • Java SDK 1.4+ for Grails 1.0.x and 1.1.x
  • Java SDK 1.5+ for Grails 1.2 or greater (For this tutorial make sure you have JDK 1.5+ installed)


Install Grails

Option 1: Using GVM (Recommended)

If you’ve installed groovy using GVM, you can use the GVM to install grails too. use:

gvm install grails
centos grails

centos grails

Option 2: Manual Installation

We’d go by the official Grails manual:

The folder we’ll install Grails is: /usr/grails, but you can choose any other as you like.

Init Folder

cd /usr
mkdir grails
cd grails

Here we’ll put the grails files by version.

Visit the download page to get the latest version. as for now it’s 2.3.7

wget http://dist.springframework.org.s3.amazonaws.com/release/GRAILS/grails-2.3.7.zip
unzip grails-2.3.7.zip
rm grails-2.3.7.zip

Install wget & unzip if you don’t yet have them install by: yum install wget unzip

add the following to your ~/.bash_profile or ~/.bash_rc (or wherever you init your user environment):

# grails
export GRAILS_HOME=/usr/grails/grails-2.3.7

That’s it

Option 3: Using GIT

If you want to be updated with latest patches (and bugs) you can clone the git repo.

Prerequisities: you should have JDK installed, your JAVA_HOME set and GIT installed (yum install git).

For the 2.0.x and the ‘master’ branch:

cd /usr
git clone https://github.com/grails/grails-core
cd grails-core && ./gradlew install

and set your GRAILS_HOME in the ~/.bash_profile (or ~.bash_rc):

# grails
export GRAILS_HOME=/usr/grails-core

If you want to install older branch read here.


Testing grails

Type at command:

grails --version

You should get something like this output (depend on version)



That’s It! you have centos grails installed.

CentOS Groovy installation tutorial for newbs – CentOS 6.x

CentOS Groovy

CentOS Groovy installation instruction for newbs.




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


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


  • 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. 


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

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

# Groovy
export GROOVY_HOME=/usr/groovy/groovy-2.3.0-beta-2


Test Groovy

groovy -e ‘println(“Hello, World!”)’

centos groovy

centos groovy


And that’s it! You have Groovy Installed.
