Running the server

Start using scripts

Start the server using the start.sh script.

./start.sh

The logs can be found in logs directory (unless specified otherwise in the configuration).

Stopping the server again is as simple as running.

./stop.sh

Starting Manually

If desired, Thalos can also be started manually for quick configuration testing.

./bin/thalos-server

Or, if you want to specify a different config file than the default:

./bin/thalos-server --config /path/to/thalos.yml

With systemd

sudo systemctl enable thalos-server
sudo systemctl start thalos-server

After executing these commands, the server should be up and running. You can inspect logs with sudo journalctl -u thalos-server -f, or check the directory configured in log.directory (commonly /var/log/thalos on Debian packages).

TIP: if you want to modify the arguments passed to thalos-server when starting via systemd, look in the /etc/sysconfig/thalos-server file
