# 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](https://github.com/filecoin-project/lotus/tree/master/scripts) 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:
|
|
|
|
```sh
|
|
$ sudo make install
|
|
```
|
|
|
|
for `lotus` and `lotus-storage-miner` and
|
|
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
$ sudo make install-services
|
|
```
|
|
|
|
To install the the `lotus-chainwatch` service run:
|
|
|
|
```sh
|
|
$ sudo make install-chainwatch-service
|
|
```
|
|
|
|
You can install all services together by running:
|
|
|
|
```sh
|
|
$ sudo make install-all-services
|
|
```
|
|
|
|
The `lotus-daemon` and the `lotus-miner` services can be installed individually too by running:
|
|
|
|
```sh
|
|
$ sudo make install-daemon-service
|
|
```
|
|
|
|
and
|
|
|
|
```sh
|
|
$ sudo make install-miner-service
|
|
```
|
|
|
|
### Notes
|
|
|
|
When installing 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:
|
|
|
|
```sh
|
|
$ sudo make clean-all-services
|
|
```
|
|
|
|
Individual services can be removed by running:
|
|
|
|
```sh
|
|
$ sudo make clean-chainwatch-services
|
|
$ sudo make clean-miner-services
|
|
$ sudo make clean-daemon-services
|
|
```
|
|
|
|
### Notes
|
|
|
|
The services will be stoppend and disabled when removed.
|
|
|
|
Removing the `lotus-daemon` service will automatically remove the depending services `lotus-miner` and `lotus-chainwatch`.
|
|
|
|
|
|
## Controlling services
|
|
|
|
All service can be controlled with the `systemctl`. A few basic control commands are listed below. To get detailed infos about the cpabilities of the `systemctl` command please consult your distributions man pages by running:
|
|
|
|
```sh
|
|
$ man systemctl
|
|
```
|
|
|
|
### Start/Stop services
|
|
|
|
You can start the services by running:
|
|
|
|
```sh
|
|
$ sudo systemctl start lotus-daemon
|
|
$ sudo systemctl start lotus-miner
|
|
$ sudo systemctl start lotus-chainwatch
|
|
```
|
|
|
|
and can be stopped by running:
|
|
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
$ sudo systemctl enable lotus-daemon
|
|
$ sudo systemctl enable lotus-miner
|
|
$ sudo systemctl enable lotus-chainwatch
|
|
```
|
|
|
|
To disable the services on startup run:
|
|
|
|
```sh
|
|
$ 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 requirements. 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
|
|
|
|
```sh
|
|
$ sudo journalctl -u lotus-daemon -f
|
|
```
|
|
|
|
### View logs in reverse order
|
|
|
|
```sh
|
|
$ sudo journalctl -u lotus-miner -r
|
|
```
|
|
|
|
### Log files
|
|
|
|
Besides the systemd service logs all services save their own log files in `/var/log/lotus/`.
