I have 1 Lime Single Board Computer, 960MHz Dual core CPU, 512MB RAM.
I installed dump1090-fa as well as piaware and piaware-web, it used to work on the browser. Recently it is unreacheable to the piaware-web as well as the dump1090-fa map.
Any solution to fix this issue? @abcd567 . Thanks in advance.
Best regards.

root@lime-XRANGE-82519:~#
Thanks again.
sudo chown -R www-data:www-data /var/log/lighttpd/
sudo systemctl restart lighttpd
Hopefully suggestion by @wiedehopf should solve the problem.
Does this solution survive a reboot?
If not, what is the output of following command?
cat /etc/fstab
Does the output contain a line like below?
tmpfs /var/log tmpfs
I have asked this question because I have experienced this problem on Flightradar24’s Pi24 image couple of years ago, and found that the folder /var/log of Pi24 image was on volatile memory (ram). As a result, the folder /var/log/lighttpd got erased on reboot, and lighttpd was NOT able to recreate it (this folder is created once only at the time of installation of lighttpd). I solved it by adding following lines to /etc/rc.local
mkdir -p /var/log/lighttpd
touch /var/log/lighttpd/error.log
chmod 666 /var/log/lighttpd/error.log
systemctl restart lighttpd
A better way to solve it is adding following lines just above the line starting with ExecStart= in file /usr/lib/systemd/system/lighttpd.service
ExecStartPre=/bin/mkdir -p /var/log/lighttpd
ExecStartPre=/bin/touch /var/log/lighttpd/error.log
ExecStartPre=/bin/chmod 666 /var/log/lighttpd/error.log
@wiedehopf , you have save my piaware installation. Thanks.
I did reboot and it still work. At least I don’t need to format and re-image the OS and re-install again.
Best Regards.
Hi @abcd567,
I’m using the suggestion from @wiedehopf and it works even after reboot, thanks for your guides for the adding of lighttpd.
Best regards.
