On the Ignition Downloads page, scroll down to System Installers which contains all the download zip files.
Download the Ignition-buildx.x.x-osx.zip file. Note: Depending on your computer, you may need to run all the commands as root. Prefix everything with sudo or first run sudo su.
Click on the download button under JRE. Accept the license agreement and download jre-7uXX-macosx-x64.dmg. Once downloaded, run the installer and follow the instructions to install Java.
Unzip the Ignition download file and install Ignition into /usr/local/ignition by running the following command: unzip <<ignition-macosx.zip>> -d /usr/local/ignition
where <<ignition-macosx.zip>> is the path to the Ignition Mac OS X distribution you downloaded.
Change directories to the Ignition install directory. cd /usr/local/ignition
Make the files executable by executing the following three chmod commands: chmod +x ignition.sh chmod +x ignition-gateway chmod +x gcu.sh
To turn the application into a service, create a symlink to ignition.sh in /usr/local/bin cd /usr/local/bin ln -s /usr/local/ignition/ignition.sh ignition chmod +x ignition
To start Ignition now, type /usr/local/bin/ignition start
You can now open a web browser and go to the Gateway home page at http://localhost:8088.
For information about how to stop and uninstall the service, see the README file.
