I have installed greengrass core software and started it via:
sudo tar -xzvf greengrass-OS-architecture-1.11.0.tar.gz -C /
sudo tar -xzvf hash-setup.tar.gz -C /greengrass
cd /greengrass/certs/
sudo wget -O root.ca.pem https://www.amazontrust.com/repository/AmazonRootCA1.pem
cd /greengrass/ggc/core/
sudo ./greengrassd start
Verified that process is started via:
ps aux | grep PID-number
ps aux | grep -E 'greengrass.*daemon'
How to stop greengrass core?
For this, you need to run the following commands,
cd /greengrass-root/ggc/core/
sudo ./greengrassd stop
