Parity-ethereum: Run parity as a system service on Ubuntu

[schmidsi]

I followed the instructions in the FAQ but the following command fails:

sudo systemctl enable io.parity.ethereum
> Failed to execute operation: No such file or directory

Furthermore, I want to configure this service to run on the Kovan chain. So the question is:

• Is there a predefined possibility to run parity as a service on Ubuntu (or Linux in general)
• If yes, how can I configure it to run on the Kovan chain. Furthermore: unlock accounts, etc. Basically everything that can be configured
• If no: Can someone point me how to do this? Where do I find the installed binaries? How to create a systemctl service by myself, ... I'm happy to write the instructions back here in the wiki or somewhere.

The FAQ only covers macos. For Ubuntu, try the following:

• Service file can be found here: https://github.com/paritytech/parity/blob/master/scripts/parity.service

  sudo wget https://raw.githubusercontent.com/paritytech/parity/master/scripts/parity.service -O /etc/systemd/system/parity.service
  sudo chmod +x /etc/systemd/system/parity.service
  sudo systemctl enable parity
  sudo systemctl start parity
  

• For default configuration with Kovan, please check the wiki for the default config file options: https://github.com/paritytech/parity/wiki/Configuring-Parity#config-file

  [parity]
  chain = "kovan"
  

Hope that answers your questions.

Worked perfectly. Thanks for pointing out. I documented our setup publicly, so this could maybe help others too.

[5chdn]

Updated the docs. :)

Since this is the top google result for 'parity systemd', I'd like to note that the current systemd unit file is located here: https://github.com/openethereum/openethereum/blob/master/scripts/openethereum.service
