Before installing or using Grails, set JAVA_HOME environment variable:
1. Add the following to ~/.profile
export JAVA_HOME=/usr/local/jdk1.6.0_27/
export PATH=$PATH:/usr/local/jdk1.6.0_27/bin
Location will be where JDK is installed to.
2. Log out and back in again, run echo $JAVA_HOME and echo $PATH to confirm. Also check by typing java -version.
To install Grails:
1. Download grails from http://www.grails.org/Download
2. Extract the archive into a home directory. Typically /usr/local in Linux
3. Append a reference to grails as a variable, as with JAVA_HOME above
export GRAILS_HOME=/usr/local/grails-1.3.7/
export PATH=$PATH:/usr/local/grails-1.3.7/bin
Location path will be the directory you saved the extracted files to.
4. Log out and back in again.
5. Type grails in a terminal window to test. You should see:
