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 and Debian derived distributions
$ git clone https://github.com/TwistTheNeil/openmrs-automated-install.git $ cd openmrs-automated-install $ sudo bash linux-install.sh
Support for Mac will be merged as soon as bugs are squashed.
Since this script is opensource, support for more systems may be added soon.
