Hello,
I'm using Apache2 on a Raspberry Pi to provide a UI for controlling my robot. My robot control page contains javascript which in turn calls a cgi function. Within the CGI function I open a serial port and output a string then close the port again. My problem is that opening the serial port within the CGI fails because of permission problems. If I do a chmod on the serial port dev and allow everyone to read/write the port, everything works. What I want to do is put whatever user Apache2 is running as when trying to access the serial port into a group that is granted serial port dev access. Anyone know what user that would be?
Thanks for listening |

Depends on the linux you run on your pi. If it is debian based the user is www-run
However you can see user using htop (better version of top). And you can define the user and group apache is running on in apache2.conf
If you have a different pi OS let uns know. |
