Use Lotus with systemd
Lotus is capable of running as a systemd service daemon. You can find installable service files for systemd in the lotus repo scripts directory as files with .service extension. In order to install these service files, you can copy these .service files to the default systemd unit load path.
The services expect their binaries to be present in /usr/local/bin/. You can use make to install them by running:
$ sudo make install
for lotus(-daemon) and lotus-storage-miner and
$ sudo make install-chainwatch
for the chainwatch tool.
Installing services via make
If your host uses the default systemd unit load path, the lotus-daemon and lotus-miner services can be installed by running:
$ sudo make install-services
To install the the lotus-chainwatch service run:
$ sudo make install-chainwatch-service
You can install all services together by running:
$ sudo make install-all-services
The lotus-daemon and the lotus-miner services can be installed individually too by running:
$ sudo make install-daemon-service
and
$ sudo make install-miner-service
Notes
When nstalling the lotus-miner and/or lotus-chainwatch service the lotus-daemon service gets automatically installed since the other two services depend on it being installed to run.
All install *service* commands will install the latest binaries in the lotus build folders to /usr/local/bin/. If you do not want to use the latest build binaries please copy the *.service files by hand.
Removing via make
All services can beremoved via make. To remove all services together run:
$ sudo make clean-all-services
Individual services can be removed by running:
$ sudo make clean-chainwatch-services
$ sudo make clean-miner-services
$ sudo make clean-daemon-services
Notes
Removing the lotus-daemon service will automatically remove the depending services lotus-miner and lotus-chainwatch
Controlling services
Start/Stop
You can start the services by running:
$ sudo systemctl start lotus-daemon
$ sudo systemctl start lotus-miner
$ sudo systemctl start lotus-chainwatch
and can be stopped by running:
$ sudo systemctl stop lotus-daemon
$ sudo systemctl stop lotus-miner
$ sudo systemctl stop lotus-chainwatch
Enabling services on startup
To enable the services to run automatically on startup execute:
$ sudo systemctl enable lotus-daemon
$ sudo systemctl enable lotus-miner
$ sudo systemctl enable lotus-chainwatch
To disable the services on startup run:
$ sudo systemctl disable lotus-daemon
$ sudo systemctl disable lotus-miner
$ sudo systemctl disable lotus-chainwatch
Notes
Systemd will not let services be enabled or started without their dependencies. Starting the lotus-chainwatch and/or lotus-miner service with automatically start the lotus-daemon service (if installed!). Stopping the lotus-daemon service will stop the other two services. The same pattern is executed for enabling and disabling the services.
Interacting with service logs
Logs from the services can be reviewed using journalctl.
Follow logs from a specific service unit
$ sudo journalctl -u lotus-daemon -f
View logs in reverse order
$ sudo journalctl -u lotus-miner -r
Log files
Besides the systemd service logs all services save their own log files in /var/log/lotus/.
