Currently Sumo Logic does not create a default systemd start up script with the installation of the Collector.
After the installation of the Collector via RPM, Deb, .tar or .sh scripts you can manually create a systemd start script (sumologic.service) to start the Collector at boot time. Below is a template used to create this service script. You just need to place this within "/usr/lib/systemd/system" directory and then set the script to be executable.
Description=Sumo Logic Collector
# Give a reasonable amount of time for the server to start up/shut down
Once you have the file in place kill any running Collector process on the host and then run the following command.
sudo systemctl enable sumologic.service
You can then start/stop/restart the service with the following commands.
sudo systemctl stop sumologic.service
sudo systemctl start sumologic.service
