This unofficial guide is based on my personal experience on aura staking and I am not associated with Aurora nor its associates. The provided contents comes with no warranty. You may freely use and modify the software according to your needs.
Aura staking setup
- SSH to your node and run following script section to install aurad and dependencies.
curl -O https://raw.githubusercontent.com/kokleong98/aura-setup/master/aura-deploy.sh
chmod +x aura-deploy.sh
sudo ./aura-deploy.sh- Login with the new user account you have setup on step 1.
- Run following to configure your staking.
aura config
- Fill in your cold wallet address and sign it with ether wallet.
Install aura as systemd service auto run aura at system reboot. This have depedency on nvm. The service include following functionality.
- Monitoring staking offline and auto restart aura.
- Auto aura start on system reboot and aura.service failures.
- Email notification when staking offline (disabled by default, need configuration on aura-start.sh).
- Aurad block sync wait at aura.service start-up.
- Auto restart aurad container when stuck during Aurad block sync stage.
- Aurad software update email notification.
- Support "aura.conf" configuration file.
- **Keep overall monitor service CPU consumption max range (4% - 6%) (Trying to uphold this.)
- **Staking online statistics logging (In development)
Make sure you have finished sync with the network before starting aura.service else it will restart aura because staking is offline.
- SSH to your node and run following script section to install aurad service and key in username setup during aura-setup. *You may be prompt for sudo password.
curl -O https://raw.githubusercontent.com/kokleong98/aura-setup/master/aura-service-install.sh
chmod +x aura-service-install.sh
sudo ./aura-service-install.sh
You shall see 2 service shell script files (aura-start.sh, aura-stop.sh) created and 1 systemd aura service file (aura.service) created.
