Allow file uploads
sudo groupadd varwwwusers sudo adduser www-data varwwwusers sudo chgrp -R varwwwusers /var/www/ sudo chmod -R 760 /var/www/
www-data to the
varwwwusers group, which is then set as the group for
/var/www/ and all of its subfolders.
chmod will give read, write, execute permissions to the owner but the group will not be able to execute any script potentially uploaded in there if for example the webserver got hacked.
You could set it to
740 to make it more secure but then you won’t be able to use
collectstatic functionality so stick to
760 unless you’re very confident about what you’re doing.
