So I followed this youtube video on setting up RTL-433 service on a Ubuntu server. Problem is, it seems to keep failing after a while. Sometimes doing a systemctl start service doesn’t work and I will have to reboot the system and then it will work. It will work for a while and later in the day it will suddenly stop. Sometimes I can do a systemctl start, but sometimes not.
Anyone know how I can have this service constantly up and running, and restart if it fails?
To have it automatically restart on failure, you can add the following to your systemd unit:
[Service] Restart=on-failure RestartSec=5s
See this blog post for more information.
But to find the root cause of why it’s failing, you can run
systemctl status <service>
when it fails to get the most recent logs and hopefully an error as to why it failed.Still relatively beginner, but wouldn’t ‘journalctl -u nameofservice.service’ also give you in depth logs over a longer period of time?
Adding to this,
journalctl -fu service
will jump to the bottom of the log and effectivelytail -F
the log so any new output will be appended to your terminalI second
journalctl -f -u SERVICE_NAME.service
it’s great and just works well. The.service
isn’t required, but it’s a good habit to get into since systemd also has mounts and timers.
