Set up InfluxDB Clustered

As you get started with this tutorial, do the following to make sure everything you need is in place.

• Install and configure your InfluxDB cluster
• Download, install, and configure the influxctl CLI
• Create a database
• Create a database token
• Configure authentication credentials

Install and configure your InfluxDB cluster

Follow the Install InfluxDB Clustered guide to install prerequisites and set up your cluster.

Download, install, and configure the influxctl CLI

The influxctl CLI lets you manage your InfluxDB cluster from a command line and perform administrative tasks such as managing databases and tokens.

1. Download and install the influxctl CLI.

2. Create a connection profile and provide your InfluxDB Clustered connection credentials.

   The influxctl CLI uses connection profiles to connect to and authenticate with your InfluxDB cluster.

   Create a file named config.toml at the following location depending on your operating system.

   Operating system	Default profile configuration file path
   Linux	~/.config/influxctl/config.toml
   macOS	~/Library/Application Support/influxctl/config.toml
   Windows	%APPDATA%\influxctl\config.toml

   If stored at a non-default location, include the --config flag with each influxctl command and provide the path to your profile configuration file.

3. Copy and paste the sample configuration profile code into your config.toml:

[[profile]]
  name = "default"
  product = "clustered"
  host = "cluster-host.com"
  port = "
PORT
"

[profile.auth.oauth2]
  client_id = "
OAUTH_CLIENT_ID
"
  scopes = [""]
  token_url = "
OAUTH_TOKEN_URL
"
  device_url = "
OAUTH_DEVICE_URL
"

Replace the following with your InfluxDB Clustered credentials:

• PORT: the port to use to access your InfluxDB cluster
• OAUTH_CLIENT_ID: the client URL of your OAuth2 provider (for example: https://identityprovider/oauth2/v2/token)
• OAUTH_DEVICE_ID: the device URL of your OAuth2 provider (for example: https://identityprovider/oauth2/v2/auth/device)

For detailed information about influxctl profiles, see Configure connection profiles.

Create a database

Use the influxctl database create command to create a database. You can use an existing database or create a new one specifically for this getting started tutorial. Examples in this getting started tutorial assume a database named get-started.

Provide the following:

• Database name.
• Optional: Database retention period as a duration value. If no retention period is specified, the default is infinite.

influxctl database create --retention-period 
1y
 
get-started

Create a database token

Use the influxctl token create command to create a database token with read and write permissions for your database.

Provide the following:

• Permission grants
  • --read-database: Grants read access to a database
  • --write-database Grants write access to a database
• Token description

influxctl token create \
  --read-database 
get-started
 \
  --write-database 
get-started
 \
  "Read/write token for 
get-started
 database"

The command returns the token ID and the token string. Store the token string in a safe place. You’ll need it later. This is the only time the token string is available in plain text.

Configure authentication credentials

Code samples in later sections assume you assigned the token string to an INFLUX_TOKEN environment variable–for example:

export INFLUX_TOKEN=
DATABASE_TOKEN

$env:INFLUX_TOKEN = "
DATABASE_TOKEN
"

set INFLUX_TOKEN=
DATABASE_TOKEN
 
# Make sure to include a space character at the end of this command.

Replace DATABASE_TOKEN with your database token string.
