I recently needed a way to run unit tests on Travis for a project that uses Sun Grid Engine, Grid Map. Unfortunately, it seemed like no one had figured out how to set that up on Travis before (or simply create a single-machine installation without any user interaction). After hours of trial-and-error, I now know the secrets to making a single-machine installation of SGE that runs on Travis, and I'm sharing my script to prevent other people from going through the same frustrating experience.

To use the install_sge.sh script below, you just need to copy all of the files in this gist to a travis sub-directory directly under the root of your GitHub project, and add the following lines to your .travis.yml

before_install:
  - travis/install_sge.sh
  - export SGE_ROOT=/var/lib/gridengine
  - export SGE_CELL=default
  - export DRMAA_LIBRARY_PATH=/usr/lib/libdrmaa.so.1.0

	#!/bin/bash
	# bash generate random alphanumeric string
	#

	# bash generate random 32 character alphanumeric string (upper and lowercase) and
	NEW_UUID=$(cat /dev/urandom \| tr -dc 'a-zA-Z0-9' \| fold -w 32 \| head -n 1)

	# bash generate random 32 character alphanumeric string (lowercase only)
	cat /dev/urandom \| tr -dc 'a-z0-9' \| fold -w 32 \| head -n 1

	To install virtualenv via pip
	$ pip3 install virtualenv

	Note that virtualenv installs to the python3 directory. For me it's:
	$ /usr/local/share/python3/virtualenv

	Create a virtualenvs directory to store all virtual environments
	$ mkdir somewhere/virtualenvs

	Make a new virtual environment with no packages
