Answer 1

To set environment variable temporary, you need to open terminal and execute in the command line:

export PENTAHO_JAVA_HOME=/some/path/where/java/located

If you need it persistent, you can add above line at the end of your shell configuration file. Usually, shell config file is named: ~/.profile, ~/.bashrc

So, look for any of files above. If no files, create ~/.profile file:

touch ~/.profile

and place the command line above into it (using any text editor you prefer most).

Re-login/re-boot might be necessary.

To check if you have the variabled successfully set, you can execure such command in the terminal:

echo $PENTAHO_JAVA_HOME

It will show value of the variable.
