I've been working with GPS systems for the last 4.5 years, and have been programming since 1979
True installing Traccar is quite simple, the thing is if you follow the quick start/basic installation instructions on the Traccar site you have a limited installation that is not really production ready.
You should really set it up with MySQL since that is a "real" database that can handle a production environment
.
It is also best to install the Web UI mod too, it adds many features to Traccar.
This bid is to install the Basic Traccar (no MySQL or Web UI mod) on a compatible Linux VPS
If you have any questions regarding MySQL or the Web UI mod please feel free to contact me.
