HTML perms issue for 5.0

[Rob Cranfill]

Hey, all!

Just upgraded to 5.02 from 4.10.something, and now WeeWX can't output to my web server directory. I'm sure it's some dumb permissions thing I'm missing, but I am not seeing it.

I get a bazillion errors like this in the log:

Jun 01 12:16:15 pi4 weewxd[3424852]: ERROR weewx.imagegenerator: Unable to save to file '/var/www/html/weather/daybarometer.png' [Errno 13] Permission denied: '/var/www/html/weather/daybarometer.png':

My new install is running as user weewx, as intended:
rob@pi4: $ ps aux | grep wee
weewx    3424852  4.9  2.8 358576 53528 ?        Ssl  11:38   1:42 python3 /usr/share/weewx/weewxd.py /etc/weewx/weewx.conf

I added that user to some groups (for my USB interface and the HTML directory)
rob@pi4: $ groups weewx
weewx : weewx dialout www-data

And here are the permissions along that directory path. See anything untowards?
drwxr-xr-x 12 root root 4.0K Dec  7 20:36 /var
drwxr-xr-x 3 root root 4.0K Dec  7 20:36 /var/www/
drwxr-xr-x 4 www-data www-data 4.0K Jun  1 10:58 /var/www/html/
drwxrwxr-x 6 www-data www-data 4.0K Jun  1 11:25 /var/www/html/weather/

Thanks for any suggestions. I can post more info if that will help. The logs show nothing else interesting that I can see.

There might be files left over from pre-upgrade that are still owned by www-data (daybarometer.png, for example). I'd just go into the /var/www/html/weather/ directory and remove everything and let weewx build new ones. Or, chown weewx:weewx * in the weather directory

Thanks for the idea, but that didn't fix it.

I would "sudo chown -R weewx:weewx /var/www/html/weather" so the directory and its contents are owned by the weewx user that the weewx process runs as.

That seems to have done it! Thanks :)

One odd thing: I had to copy the old seasons.css and seasons.js files over, by hand. Whatev.
