This README provides step-by-step instructions for setting up Druid in a local standalone mode on an Ubuntu machine. Please ensure you meet the prerequisites before starting.

• A machine with a minimum of 5 GB RAM. If using AWS, consider the t2.large instance type and allow incoming traffic on port 8888 in the security group.

• Java is a prerequisite. Install it with the following command:

  sudo apt install default-jre
  

1. Download and extract Druid:

   cd /home/ubuntu/downloads
   wget https://dlcdn.apache.org/druid/27.0.0/apache-druid-27.0.0-bin.tar.gz
   tar -xzf apache-druid-27.0.0-bin.tar.gz
   

2. Create a systemd service (use ROOT user for this):

   • Create a service file:

     vi /etc/systemd/system/druid.service
     

   • Paste the text from the druid.service file available in this repository.

   • Reload the systemd manager configuration:

     systemctl daemon-reload
     

   • Enable the Druid service to start on boot:

     systemctl enable druid
     

   • Start the Druid service:

     systemctl start druid
     

3. Check the service status:

   systemctl status druid
   

The service should be in the active state. Wait for 2-3 minutes.

4. Access the Druid web console @{public-ip}:8888

   

• If you're getting a connection refused, check the status of the service. There might be some configuration or Druid start-up issues.
• If you're getting a connection timed out, check the security group. You might have missed enabling the 8888 port in the security group.
