There are unofficial scripts available on GitHub which would ease the installation of OpenMRS on select systems.
https://github.com/TwistTheNeil/openmrs-automated-install
Linux support is available for Debian, Debian derived distributions, Fedora
$ git clone https://github.com/TwistTheNeil/openmrs-automated-install.git $ cd openmrs-automated-install $ sudo bash linux-install.sh
Mac OSX support is contributed to the repo and works as such:
$ git clone https://github.com/TwistTheNeil/openmrs-automated-install.git $ cd openmrs-automated-install $ ./mac-install.sh
Since this script is opensource, support for more systems may be added soon.
