Running Chia as a service has several benefits, the main one being this always ensures your node / farm is running. Example given: When your farm reboots unexpectedly the service will auto start your farm after boot. You can also use this to autostart your node or harvester (change the startup script accordingly).

Use your prefered editor to create the following text file and save it (eg: startfarm.sh)

Note: Replace {USERNAME} with the name of the user having Chia installed.

#!/bin/bash
/usr/bin/env bash -c 'cd /home/{USERNAME}/chia-blockchain && . ./activate && chia start farmer' 2>/dev/null

After saving use chmod +x startfarm.sh to set the correct permissions. You can now execute the script to test if this starts up your farm: ./startfarm.sh.

Create the Chia service: nano /etc/systemd/system/chia.service and paste the following service:

Note: Replace {USERNAME} (3x) with the name of the user having Chia installed.

[Unit]
Description=Chia Service
[Service]
Type=forking
RemainAfterExit=no
User={username}
WorkingDirectory=/home/{username}/chia-blockchain
ExecStart=/home/{username}/startfarm.sh
Restart=always
[Install]
WantedBy=multi-user.target

Create the Chia service: sudo nano /etc/systemd/system/chia.service and paste the following service:

Note: Replace {USERNAME} (3x) with the name of the user having Chia installed.

[Unit]
Description=Chia Service
[Service]
Type=forking
RemainAfterExit=no
User={username}
WorkingDirectory=/home/{username}/chia-blockchain
ExecStart=/home/{username}/startfarm.sh
Restart=always
[Install]
WantedBy=multi-user.target

You should now be able to see the service running sudo systemctl status chia:

$ sudo systemctl status chia
● chia.service - Chia Service
   Loaded: loaded (/etc/systemd/system/chia.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

Enable the service by running: sudo systemctl enable chia Start the service by running: sudo systemctl start chia

When you reboot the system, Chia should automatically start up.
