Firewall & Access

Port	Service	Purpose
22	SSH (rate limited)	Secure server access
8086	InfluxDB Web UI/API	Data ingestion and queries

Initial Deployment

During the deployment process:

• InfluxDB is automatically installed and enabled as a service
• Initial setup is required via web interface or CLI

You will be logged out with the message:

Please wait until the installation is completed....
Connection to $IPADDRESS closed.

Wait at least 2 minutes before logging back in.

Accessing the Instance

1. Login to your instance:

ssh ubuntu@$IPADDRESS

2. Switch to root:

sudo su -

Web Interface Setup

• Open your browser and go to:

http://$IPADDRESS:8086

• Follow the on-screen steps to set up:
  • Username and password
  • Initial organization and bucket
  • Retention policies and access tokens

CLI-Based Setup (Alternative)

InfluxDB can also be configured using the CLI:

influx setup

Follow the interactive prompts to configure user, organization, bucket, and tokens.

Refer to official documentation:

• InfluxDB Setup Guide
• Influx CLI Documentation

Useful CLI Commands

Once setup is complete, you can use commands such as:

influx bucket list
influx org list
influx write --bucket <bucket_name> --org <org_name> --precision s
influx query 'from(bucket: "<bucket_name>") |> range(start: -1h)'

Best Practices

• Ensure strong credentials during setup
• Enable firewall restrictions to only trusted IPs
• Use tokens for external access to API
• Regularly monitor disk usage and retention policies
• Set up HTTPS proxy (e.g., NGINX) for production deployments
