See the influxd documentation for information about available flags and options.

influxd --reporting-disabled

Download and install InfluxDB v2.2

Do one of the following:

• Install InfluxDB as a service with systemd
• Manually download and install the influxd binary

Install InfluxDB as a service with systemd

1. Download and install the appropriate .deb or .rpm file using either:

   • apt or yum with the following commands:

     # influxdata-archive_compat.key GPG Fingerprint: 9D539D90D3328DC7D6C8D3B9D8FF8E1F7DF8B07E
     
     # Ubuntu/Debian
     wget -q https://repos.influxdata.com/influxdata-archive_compat.key
     echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
     echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list
     sudo apt-get update && sudo apt-get install influxdb2
     
     # Red Hat/CentOS/Fedora
     cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
     [influxdb]
     name = InfluxDB Repository - RHEL \$releasever
     baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable
     enabled = 1
     gpgcheck = 1
     gpgkey = https://repos.influxdata.com/influxdata-archive_compat.key
     EOF
     sudo yum install influxdb2
     

   • or via a URL from the InfluxData downloads page with the following commands:

     # Ubuntu/Debian
     wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.2.0-xxx.deb
     sudo dpkg -i influxdb2-2.2.0-xxx.deb
     
     # Red Hat/CentOS/Fedora
     wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.2.0-xxx.rpm
     sudo yum localinstall influxdb2-2.2.0-xxx.rpm
     

     Use the exact filename of the download of .rpm package (for example, influxdb2-2.2.0-amd64.rpm).

2. Start the InfluxDB service:

   sudo service influxdb start
   

   Installing the InfluxDB package creates a service file at /lib/systemd/services/influxdb.service to start InfluxDB as a background service on startup.

3. Restart your system and verify that the service is running correctly:

   $  sudo service influxdb status
   ● influxdb.service - InfluxDB is an open-source, distributed, time series database
     Loaded: loaded (/lib/systemd/system/influxdb.service; enabled; vendor preset: enable>
     Active: active (running)
   

For information about where InfluxDB stores data on disk when running as a service, see File system layout.

To customize your InfluxDB configuration, use either command line flags (arguments), environment variables, or an InfluxDB configuration file. See InfluxDB configuration options for more information.

Pass arguments to systemd

1. Add one or more lines like the following containing arguments for influxd to /etc/default/influxdb2:

   ARG1="--http-bind-address :8087"
   ARG2="<another argument here>"
   

2. Edit the /lib/systemd/system/influxdb.service file as follows:

   ExecStart=/usr/bin/influxd $ARG1 $ARG2
   

Manually download and install the influxd binary

1. Download the InfluxDB binary.

   Download the InfluxDB binary from your browser or from the command line.

   Download from your browser

   InfluxDB v2.2 (amd64) InfluxDB v2.2 (arm)

   Download from the command line

   # amd64
   wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.2.0-linux-amd64.tar.gz
   
   # arm
   wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.2.0-linux-arm64.tar.gz
   

2. Extract the downloaded binary.

   Note: The following commands are examples. Adjust the filenames, paths, and utilities if necessary.

   # amd64
   tar xvzf path/to/influxdb2-2.2.0-linux-amd64.tar.gz
   
   # arm
   tar xvzf path/to/influxdb2-2.2.0-linux-arm64.tar.gz
   

3. (Optional) Place the extracted influxd executable binary in your system $PATH.

   # amd64
   sudo cp influxdb2-2.2.0-linux-amd64/influxd /usr/local/bin/
   
   # arm
   sudo cp influxdb2-2.2.0-linux-arm64/influxd /usr/local/bin/
   

   If you do not move the influxd binary into your $PATH, prefix the executable ./ to run it in place.

Start InfluxDB

If InfluxDB was installed as a systemd service, systemd manages the influxd daemon and no further action is required. If the binary was manually downloaded and added to the system $PATH, start the influxd daemon with the following command:

influxd

See the influxd documentation for information about available flags and options.

Networking ports

By default, InfluxDB uses TCP port 8086 for client-server communication over the InfluxDB HTTP API.

influxd --reporting-disabled

Download and install InfluxDB v2.2

InfluxDB v2.2 (Windows)

Expand the downloaded archive into C:\Program Files\InfluxData\ and rename the files if desired.

> Expand-Archive .\influxdb2-2.2.0-windows-amd64.zip -DestinationPath 'C:\Program Files\InfluxData\'
> mv 'C:\Program Files\InfluxData\influxdb2-2.2.0-windows-amd64' 'C:\Program Files\InfluxData\influxdb'

Networking ports

By default, InfluxDB uses TCP port 8086 for client-server communication over the InfluxDB HTTP API.

Start InfluxDB

In Powershell, navigate into C:\Program Files\InfluxData\influxdb and start InfluxDB by running the influxd daemon:

> cd -Path 'C:\Program Files\InfluxData\influxdb'
> ./influxd

See the influxd documentation for information about available flags and options.

./influxd --reporting-disabled

Download and run InfluxDB v2.2

Use docker run to download and run the InfluxDB v2.2 Docker image. Expose port 8086, which InfluxDB uses for client-server communication over the InfluxDB HTTP API.

docker run --name influxdb -p 8086:8086 influxdb:2.2.0

To run InfluxDB in detached mode, include the -d flag in the docker run command.

Persist data outside the InfluxDB container

1. Create a new directory to store your data in and navigate into the directory.

   mkdir path/to/influxdb-docker-data-volume && cd $_
   

2. From within your new directory, run the InfluxDB Docker container with the --volume flag to persist data from /var/lib/influxdb2 inside the container to the current working directory in the host file system.

   docker run \
       --name influxdb \
       -p 8086:8086 \
       --volume $PWD:/var/lib/influxdb2 \
       influxdb:2.2.0
   

Configure InfluxDB with Docker

To mount an InfluxDB configuration file and use it from within Docker:

1. Persist data outside the InfluxDB container.

2. Use the command below to generate the default configuration file on the host file system:

   docker run \
     --rm influxdb:2.2.0 \
     influxd print-config > config.yml
   

3. Modify the default configuration, which will now be available under $PWD.

4. Start the InfluxDB container:

   docker run -p 8086:8086 \
     -v $PWD/config.yml:/etc/influxdb2/config.yml \
     influxdb:2.2.0
   

(Find more about configuring InfluxDB here.)

Open a shell in the InfluxDB container

To use the influx command line interface, open a shell in the influxdb Docker container:

docker exec -it influxdb /bin/bash

docker run -p 8086:8086 influxdb:2.2.0 --reporting-disabled

Install InfluxDB in a Kubernetes cluster

The instructions below use minikube or kind, but the steps should be similar in any Kubernetes cluster. InfluxData also makes Helm charts available.

1. Install minikube or kind.

2. Start a local cluster:

   # with minikube
   minikube start
   
   # with kind
   kind create cluster
   

3. Apply the sample InfluxDB configuration by running:

   kubectl apply -f https://raw.githubusercontent.com/influxdata/docs-v2/master/static/downloads/influxdb-k8-minikube.yaml
   

   This creates an influxdb Namespace, Service, and StatefulSet. A PersistentVolumeClaim is also created to store data written to InfluxDB.

   Important: Always inspect YAML manifests before running kubectl apply -f <url>!

4. Ensure the Pod is running:

   kubectl get pods -n influxdb
   

5. Ensure the Service is available:

   kubectl describe service -n influxdb influxdb
   

   You should see an IP address after Endpoints in the command’s output.

6. Forward port 8086 from inside the cluster to localhost:

   kubectl port-forward -n influxdb service/influxdb 8086:8086
   

Install InfluxDB v2.2 on Raspberry Pi

Install Linux binaries

Follow the Linux installation instructions to install InfluxDB on a Raspberry Pi.

Monitor your Raspberry Pi

Use the InfluxDB Raspberry Pi template to easily configure collecting and visualizing system metrics for the Raspberry Pi.

Monitor 32-bit Raspberry Pi systems

If you have a 32-bit Raspberry Pi, use Telegraf to collect and send data to:

• InfluxDB OSS, running on a 64-bit system
• InfluxDB Cloud with a Free Tier account
• InfluxDB Cloud with a paid Usage-Based account with relaxed resource restrictions.

Set up InfluxDB through the UI

1. With InfluxDB running, visit localhost:8086.
2. Click Get Started

Set up your initial user

1. Enter a Username for your initial user.
2. Enter a Password and Confirm Password for your user.
3. Enter your initial Organization Name.
4. Enter your initial Bucket Name.
5. Click Continue.

InfluxDB is now initialized with a primary user, organization, and bucket. You are ready to write or collect data.

(Optional) Set up and use the influx CLI

To avoid having to pass your InfluxDB API token with each influx command, set up a configuration profile to store your credentials. To do this, complete the following steps:

1. In a terminal, run the following command:

   # Set up a configuration profile
   influx config create -n default \
     -u http://localhost:8086 \
     -o example-org \
     -t mySuP3rS3cr3tT0keN \
     -a
   

   This configures a new profile named default and makes the profile active so your influx CLI commands run against the specified InfluxDB instance. For more detail, see influx config.

2. Learn influx CLI commands. To see all available influx commands, type influx -h or check out influx - InfluxDB command line interface.

Set up InfluxDB through the influx CLI

Begin the InfluxDB setup process via the influx CLI by running:

influx setup

1. Enter a primary username.
2. Enter a password for your user.
3. Confirm your password by entering it again.
4. Enter a name for your primary organization.
5. Enter a name for your primary bucket.
6. Enter a retention period for your primary bucket—valid units are nanoseconds (ns), microseconds (us or µs), milliseconds (ms), seconds (s), minutes (m), hours (h), days (d), and weeks (w). Enter nothing for an infinite retention period.
7. Confirm the details for your primary user, organization, and bucket.

InfluxDB is now initialized with a primary user, organization, bucket, and API token. InfluxDB also creates a configuration profile for you so that you don’t have to add your InfluxDB host, organization, and token to every command. To view that config profile, use the influx config list command.

To continue to use InfluxDB via the CLI, you need the API token created during setup. To view the token, log into the UI with the credentials created above. (For instructions, see View tokens in the InfluxDB UI.)

You are ready to write or collect data.
