centos grails

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

Prerequisities

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

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
export PATH=$PATH:$GRAILS_HOME/bin

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
export PATH=$PATH:$GRAILS_HOME/bin

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.

Cheers!
