Installation under different username --> permissions problem? #36

Closed bertmelis closed 4 years ago

bertmelis commented 6 years ago

After a successful installation on a fresh Raspbian Stretch (Lite) on a RPI1B, Pikrellcam starts nicely. However, I don't get any image. I've found the following in the logs:

make_dir(/run/pikrellcam) failed. No such file or directory
Failed to create media directories or FIFO, exiting!

The camera module works as raspistill generates an image.

ah wait, I installed it on my user account, and not pi. Is that supported?

billw2 commented 6 years ago

The user installing/running pikrellcam needs to be able to change owner/modes of directories so that the web server www-data has permission to read/write files. At least the user needs sudo privilege and permission to access the /run directory. Maybe you can set up another user to work, but I haven't done it so can't give you the set of steps you would need.

I always remove the pi user from the system and replaces it with my own with sudo and video privileges. But Pikrellcm won't display any image.

To troubleshoot I created the pi user again, reran the installation script from this user and now everything worked!

The thing I did different was that I had autostart at boot enabled the first time and I disabled it when I installed again with the pi-user.

A quick search through the repo tells me there is a command executed by user pi on this line: https://github.com/billw2/pikrellcam/blob/1697ed0ee687b7c592d9c4c40a4f291e86cebbf2/www/sys_command.php#L12
