On a Linux OS, there are a few ways to launch the Resilio Connect Tracker process at system boot as also restart it if it stops for a reason.
Linux Systemd Service
(recommended)
Create file /lib/systemd/system/resilio-connect-tracker.service (superuser's permissions required) with the following content.
[Unit]
Description=Resilio Connect Tracker Service
Documentation=https://connect.resilio.com
After=network.target
[Service]
Type=simple
UMask=0002
Restart=always
PermissionsStartOnly=true
User=<some_user>
Group=<some_group>
ExecStart=/opt/resilio-connect-tracker/tracker
[Install]
WantedBy=multi-user.target
Before starting
Replace <some_user> and <some_group> with the user and group that will run the tracker process. Put the valid path to the binary (for example /usr/bin/tracker) to ExecStart the directive.
Save the file and run the command
sudo systemctl daemon-reload
To start the service run command
sudo systemctl start resilio-connect-tracker.service
To add service to autostart run command
sudo systemctl enable resilio-connect-tracker.service
Crontab
The easiest is to add a cron task. The minimal command is below. Every minute it will check for the running process and start it if necessary. In Terminal run command crontab -e. Enter the command below, be sure to uncomment the line (remove #)
*/1 * * * * ps -A | grep "tracker( |$)" || /home/admin/tracker/tracker
Use the valid path to tracker binary instead of /home/admin/tracker/tracker
Since cron is started from a different directory, the full path to the tracker shall be specified
