Install InfluxDB

Part of FIBER Lite's complete pre-integrated software stack. Not part of a stock FIBER install.

1. Download the InfluxData repository GPG key and verify its fingerprint before trusting it:

   curl --silent --location -O https://repos.influxdata.com/influxdata-archive.key
   gpg --show-keys --with-fingerprint --with-colons ./influxdata-archive.key 2>&1 \
     | grep -q '^fpr:\+24C975CBA61A024EE1B631787C3D57159FC2F927:$' \
     && echo "fingerprint OK"

2. Add the key and repository:

   sudo mkdir -p /etc/apt/keyrings
   cat influxdata-archive.key | gpg --dearmor | sudo tee /etc/apt/keyrings/influxdata-archive.gpg > /dev/null
   rm influxdata-archive.key
   echo 'deb [signed-by=/etc/apt/keyrings/influxdata-archive.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list

3. Update the package list and install InfluxDB 2.x with its CLI:

   sudo apt update
   sudo apt install -y influxdb2 influxdb2-cli
   sudo systemctl enable --now influxdb

4. Initialize the organization, bucket, and API token non-interactively:

   influx setup --username fiberlite --password '<choose a password>' \
     --org fiber-lite --bucket fiber-lite --token "$(openssl rand -hex 32)" --force

   tip

   openssl rand -hex 32 generates a random 64-character token so you don't have to invent one. Immediately after, run influx auth list to print it back out — store it, together with the password you chose; they are needed again for the Node-RED flow above and the Grafana datasource below.
