installing grails in linux - linux

Question

I am new to using Linux. I installed grails by setting env variable GRAILS_HOME and added ot to PATH variable. I also exported both and when I typed in grails command.. It worked fine. When I closed that terminal session and opened a another new session, all the env variables that I had set up has all gone.
I was wondering how to have them available for all sessions.
Any help is appreciated
Thanks

Answer 1

Edit the .bashrc file of the user launching Grails.
Add the same lines as your commands:
GRAILS_HOME=/home/of/grails
export GRAILS_HOME
PATH=$PATH:$GRAILS_HOME/bin

Answer 2

you need to add $GRAILS_HOME/bin to the PATH (rather than $GRAILS_HOME)
Update
The best way to install Grails on Linux/Mac is to use GVM.
GVM is a 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.
In addition to Grails, you can also use GVM to manage your installation of
Groovy
Griffon
Gradle
vert.x

Answer 3

If you have an Ubuntu (or equal) installation. You could add a repository to it. It should do all the stuff for you:
sudo add-apt-repository ppa:groovy-dev/grails
sudo apt-get update
sudo apt-get install grails

Answer 4

you need to set them under ~/.bashrc file and then type source ~/.bashrc in your terminal so you don't have to close and re-open it again.

Answer 5

In /etc/profile.d/ create a script name grails.sh:
export GRAILS_HOME=/opt/grails
export PATH=$GRAILS_HOME/bin:$PATH
Change /opt/grails to where you unzipped grails.
This will make it available for all users.

Answer 6

If you are on ubuntu define the GRAILS_HOME variable with its installation path in /etc/environment and edit the system path variable as shown in second line
GRAILS_HOME=/opt/grails
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/grails2/bin:"
