Installing ThingsBoard PE on CentOS/RHEL

Prerequisites

This guide describes how to install ThingsBoard on RHEL 8/9, CentOS 8/9, or their derivatives (Alma, Rocky, Oracle, etc). Hardware requirements depend on chosen database and amount of devices connected to the system. To run ThingsBoard and PostgreSQL on a single machine you will need at least 4Gb of RAM. To run ThingsBoard and Cassandra on a single machine you will need at least 8Gb of RAM.

Before continue to installation execute the following commands in order to install necessary tools:

For CentOS 8:

# Add latest EPEL release for CentOS 9
sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

Step 1. Install Java 17 (OpenJDK)

ThingsBoard service is running on Java 17. Follow this instructions to install OpenJDK 17:

1

sudo dnf install java-17-openjdk

Please don’t forget to configure your operating system to use OpenJDK 17 by default. You can configure which version is the default using the following command:

1

sudo update-alternatives --config java

You can check the installation using the following command:

1

java -version

Expected command output is:

1
2
3

openjdk version "17.x.xx"
OpenJDK Runtime Environment (...)
OpenJDK 64-Bit Server VM (build ...)

Step 2. ThingsBoard service installation

Download installation package.

1

wget https://dist.thingsboard.io/thingsboard-3.8.1pe.rpm

Install ThingsBoard as a service

1

sudo rpm -Uvh thingsboard-3.8.1pe.rpm

Step 3. Obtain and configure license key

We assume you have already chosen your subscription plan or decided to purchase a perpetual license. If not, please navigate to pricing page to select the best license option for your case and get your license. See How-to get pay-as-you-go subscription or How-to get perpetual license for more details.

Once you get the license secret, you should put it to the thingsboard configuration file. Open the file for editing using the following command:

1

sudo nano /etc/thingsboard/conf/thingsboard.conf

Locate the following configuration block:

1
2
3

# License secret obtained from ThingsBoard License Portal (https://license.thingsboard.io)
# UNCOMMENT NEXT LINE AND PUT YOUR LICENSE SECRET:
# export TB_LICENSE_SECRET=

and put your license secret. Please don’t forget to uncomment the export statement. See example below:

1

3

# License secret obtained from ThingsBoard License Portal (https://license.thingsboard.io)
# UNCOMMENT NEXT LINE AND PUT YOUR LICENSE SECRET:
export TB_LICENSE_SECRET=YOUR_LICENSE_SECRET_HERE

Step 4. Configure ThingsBoard database

ThingsBoard is able to use SQL or hybrid database approach. See corresponding architecture page for more details.

PostgreSQL (recommended for < 5K msg/sec)
Hybrid
PostgreSQL+Cassandra
(recommended for > 5K msg/sec)
Doc info icon

ThingsBoard team recommends to use PostgreSQL for development and production environments with reasonable load (< 5000 msg/sec). Many cloud vendors support managed PostgreSQL servers which is a cost-effective solution for most of ThingsBoard instances.

PostgreSQL Installation

Instructions listed below will help you to install PostgreSQL.

# Install packages
sudo dnf -qy module disable postgresql
sudo dnf -y install postgresql16 postgresql16-server postgresql16-contrib
# Initialize your PostgreSQL DB
sudo /usr/pgsql-16/bin/postgresql-16-setup initdb
sudo systemctl start postgresql-16
# Optional: Configure PostgreSQL to start on boot
sudo systemctl enable --now postgresql-16

Once PostgreSQL is installed you may want to create a new user or set the password for the main user. The instructions below will help to set the password for main PostgreSQL user.

To switch your current user context to the postgres user, execute the following script:

1

sudo su - postgres

To be able to interact with the PostgreSQL database, enter:

1

psql

You will connect to the database as the main PostgreSQL user. To set the password, enter the following command after postgres=# :

1

\password

Enter and confirm the password. Then, press “Ctrl+D” to return to main user console.

After configuring the password, connect to the database to create thingsboard DB:

1

psql -U postgres -d postgres -h 127.0.0.1 -W

Execute create database statement

1

CREATE DATABASE thingsboard;

Then, press “Ctrl+D” twice to exit PostgreSQL.

ThingsBoard Configuration

Edit ThingsBoard configuration file

1

sudo nano /etc/thingsboard/conf/thingsboard.conf

Add the following lines to the configuration file. Don’t forget to replace “PUT_YOUR_POSTGRESQL_PASSWORD_HERE” with your real postgres user password:

# DB Configuration 
export DATABASE_TS_TYPE=sql
export SPRING_DATASOURCE_URL=jdbc:postgresql://localhost:5432/thingsboard
export SPRING_DATASOURCE_USERNAME=postgres
export SPRING_DATASOURCE_PASSWORD=PUT_YOUR_POSTGRESQL_PASSWORD_HERE
# Specify partitioning size for timestamp key-value storage. Allowed values: DAYS, MONTHS, YEARS, INDEFINITE.
export SQL_POSTGRES_TS_KV_PARTITIONING=MONTHS
Doc info icon

ThingsBoard team recommends to use Hybrid database approach if you do plan to have 1M+ devices in production or high data ingestion rate (> 5000 msg/sec). In this case, ThingsBoard will be storing timeseries data in Cassandra while continue to use PostgreSQL for main entities (devices/assets/dashboards/customers).

export CASSANDRA_KEYSPACE_NAME=thingsboard
export CASSANDRA_URL=127.0.0.1:9042
export CASSANDRA_USE_CREDENTIALS=false
export CASSANDRA_USERNAME=
export CASSANDRA_PASSWORD=

Step 5. Choose ThingsBoard queue service

ThingsBoard is able to use various messaging systems/brokers for storing the messages and communication between ThingsBoard services. How to choose the right queue implementation?

  • In Memory queue implementation is built-in and default. It is useful for development(PoC) environments and is not suitable for production deployments or any sort of cluster deployments.

  • Kafka is recommended for production deployments. This queue is used on the most of ThingsBoard production environments now. It is useful for both on-prem and private cloud deployments. It is also useful if you like to stay independent from your cloud provider. However, some providers also have managed services for Kafka. See AWS MSK for example.

  • RabbitMQ is recommended if you don’t have much load and you already have experience with this messaging system.

  • AWS SQS is a fully managed message queuing service from AWS. Useful if you plan to deploy ThingsBoard on AWS.

  • Google Pub/Sub is a fully managed message queuing service from Google. Useful if you plan to deploy ThingsBoard on Google Cloud.

  • Azure Service Bus is a fully managed message queuing service from Azure. Useful if you plan to deploy ThingsBoard on Azure.

  • Confluent Cloud is a fully managed streaming platform based on Kafka. Useful for a cloud agnostic deployments.

See corresponding architecture page and rule engine page for more details.

In Memory (built-in and default)
Kafka (recommended for on-prem, production installations)
AWS SQS (managed service from AWS)
Google Pub/Sub (managed service from Google)
Azure Service Bus (managed service from Azure)
RabbitMQ (for small on-prem installations)
Confluent Cloud (Event Streaming Platform based on Kafka)

In Memory queue is built-in and enabled by default. No additional configuration steps required.

Kafka Installation

Apache Kafka is an open-source stream-processing software platform.

# These params affect the number of requests per second from each partitions per each queue.
# Number of requests to particular Message Queue is calculated based on the formula:
# ((Number of Rule Engine and Core Queues) * (Number of partitions per Queue) + (Number of transport queues)
#  + (Number of microservices) + (Number of JS executors)) * 1000 / POLL_INTERVAL_MS
# For example, number of requests based on default parameters is:

# Rule Engine queues:
# Main 10 partitions + HighPriority 10 partitions + SequentialByOriginator 10 partitions = 30
# Core queue 10 partitions
# Transport request Queue + response Queue = 2
# Rule Engine Transport notifications Queue + Core Transport notifications Queue = 2
# Total = 44
# Number of requests per second = 44 * 1000 / 25 = 1760 requests

# Based on the use case, you can compromise latency and decrease number of partitions/requests to the queue, if the message load is low.
# By UI set the parameters - interval (1000) and partitions (1) for Rule Engine queues.
# Sample parameters to fit into 10 requests per second on a "monolith" deployment: 

export TB_QUEUE_CORE_POLL_INTERVAL_MS=1000

1
2

# Update ThingsBoard memory usage and restrict it to 2G in /etc/thingsboard/conf/thingsboard.conf
export JAVA_OPTS="$JAVA_OPTS -Xms2G -Xmx2G"

We recommend adjusting these parameters depending on your server resources. It should be set to at least 2G (gigabytes), and increased accordingly if there is additional RAM space available. Usually, you need to set it to 1/2 of your total RAM if you do not run any other memory-intensive processes (e.g. Cassandra), or to 1/3 otherwise.

Step 7. Run installation script

Once ThingsBoard service is installed and DB configuration is updated, you can execute the following script:

1

Post-installation steps

Configure HAProxy to enable HTTPS

You may want to configure HTTPS access using HAProxy. This is possible in case you are hosting ThingsBoard in the cloud and have a valid DNS name assigned to your instance. Please follow this guide to install HAProxy and generate valid SSL certificate using Let’s Encrypt.

Troubleshooting

ThingsBoard logs are stored in the following directory:

1

/var/log/thingsboard

You can issue the following command in order to check if there are any errors on the backend side:

1

cat /var/log/thingsboard/thingsboard.log | grep ERROR
