Installing ThingsBoard Edge on CentOS/RHEL Server

doc warn icon

Rules of Compatibility Between ThingsBoard Edge and ThingsBoard Server Versions:

  • A ThingsBoard Edge version X.Y.Z is compatible with the same ThingsBoard Server version X.Y.Z and any later versions.
  • A ThingsBoard Edge version X.Y.Z is NOT compatible with ThingsBoard Server versions preceding X.Y.Z.

Example: ThingsBoard Edge version 3.3.4.1 is compatible with ThingsBoard Server version 3.3.4.1 and subsequent versions (3.4.0, 3.4.1, …). However, ThingsBoard Edge version 3.4.0 is NOT compatible with ThingsBoard Server version 3.3.4.1 or any prior versions (3.3.4, 3.3.3, …). In such scenarios, ThingsBoard Server 3.3.4.1 or a preceding version must first be upgraded to ThingsBoard Server 3.4.0 or a later version.

Please ensure that the ThingsBoard Server is updated to the latest version before proceeding.

This guide describes how to install ThingsBoard Edge on RHEL/CentOS 7/8.

Manual Installation and Configuration

If for any reason you are unable to use the prepared ThingsBoard Server Instructions above, please follow the steps below. These steps will guide you through installing and configuring the Edge by yourself.

Pre-installation step

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

1

sudo yum install -y nano wget && sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.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. Configure ThingsBoard Database

ThingsBoard Edge supports SQL and hybrid database approaches. See the architecture page for details.

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

The ThingsBoard team recommends using PostgreSQL for development and production environments with moderate load (less than 5000 msg/sec). Many cloud providers offer managed PostgreSQL services, making it a cost-effective solution for most ThingsBoard deployments.

ThingsBoard Edge uses PostgreSQL database as a local storage.

To install PostgreSQL, follow the instructions below.

Update your system:

1

sudo dnf update

Install the repository RPM:

  • For CentOS/RHEL 8:
1

sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
  • For CentOS/RHEL 9:
1

sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Install packages and initialize PostgreSQL. The PostgreSQL service will automatically start every time the system boots up.

1

4

sudo dnf -qy module disable postgresql && \
sudo dnf -y install postgresql16 postgresql16-server postgresql16-contrib && \
sudo /usr/pgsql-16/bin/postgresql-16-setup initdb && \
sudo systemctl enable --now postgresql-16

Once PostgreSQL is installed, it is recommended to set the password for the PostgreSQL main user.

The following command will switch the current user to the PostgreSQL user and set the password directly in PostgreSQL.

1

sudo -u postgres psql -c "\password"

Then, enter and confirm the password.

Modify PostgreSQL’s Authentication Method (Optional)

Since ThingsBoard Edge uses the PostgreSQL database for local storage, configuring MD5 authentication ensures that only authenticated users or applications can access the database, thus protecting your data. After configuring the password, edit the pg_hba.conf file to use MD5 hashing for authentication instead of the default method (ident) for local IPv4 connections.

To replace ident with md5, run the following command:

1

sudo sed -i 's/^host\s\+all\s\+all\s\+127\.0\.0\.1\/32\s\+ident/host    all             all             127.0.0.1\/32            md5/' /var/lib/pgsql/16/data/pg_hba.conf

Then run the command that will restart the PostgreSQL service to apply configuration changes, connect to the database as a postgres user, and create the ThingsBoard Edge database (tb_edge). To connect to the PostgreSQL database, enter the PostgreSQL password.

1

sudo systemctl restart postgresql-16.service && psql -U postgres -d postgres -h 127.0.0.1 -W -c "CREATE DATABASE tb_edge;"
Doc info icon

The ThingsBoard team recommends using a hybrid database approach if you plan to manage 1M+ devices in production or handle high data ingestion rate (more than 5000 msg/sec). In this case, ThingsBoard Edge stores time-series data in Cassandra while continuing to use PostgreSQL for primary entities such as devices, assets, dashboards, and customers.

PostgreSQL Installation

To install PostgreSQL, follow the instructions below.

Update your system:

1

sudo dnf update

Install the repository RPM:

  • For CentOS/RHEL 8:
1

sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
  • For CentOS/RHEL 9:
1

sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Install packages and initialize PostgreSQL. The PostgreSQL service will automatically start every time the system boots up.

Then run the command that will restart the PostgreSQL service to apply configuration changes, connect to the database as a postgres user, and create the ThingsBoard Edge database (tb_edge). To connect to the PostgreSQL database, enter the PostgreSQL password.

1

sudo systemctl restart postgresql-16.service && psql -U postgres -d postgres -h 127.0.0.1 -W -c "CREATE DATABASE tb_edge;"
Cassandra Installation

In order to run Cassandra, install Java 11:

1

sudo apt install openjdk-11-jdk

Set Java 17 as the default version (required for ThingsBoard Edge):

1

sudo update-alternatives --config java

Add the Cassandra repository:

1

sudo nano /etc/yum.repos.d/cassandra.repo

Add the following content:

1

[cassandra]
name=Apache Cassandra
baseurl=https://redhat.cassandra.apache.org/50x/
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://downloads.apache.org/cassandra/KEYS
  • 50x for Cassandra 5.0 version series.

Update package index if necessary:

1

sudo yum update

Install Cassandra:

1

sudo yum install cassandra

Start Cassandra service:

1

sudo service cassandra start
ThingsBoard Edge Configuration

Edit ThingsBoard Edge configuration file:

1

sudo nano /etc/tb-edge/conf/tb-edge.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:

1

3
4
5

# DB Configuration 
export DATABASE_TS_TYPE=cassandra
export SPRING_DATASOURCE_URL=jdbc:postgresql://localhost:5432/tb_edge
export SPRING_DATASOURCE_USERNAME=postgres
export SPRING_DATASOURCE_PASSWORD=PUT_YOUR_POSTGRESQL_PASSWORD_HERE

You can optionally add the following parameters to reconfigure your ThingsBoard Edge instance to connect to external Cassandra nodes:

1
2
3
4

6

export CASSANDRA_CLUSTER_NAME=Edge Cluster
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 3. Choose Queue Service

ThingsBoard Edge is able to use different 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.

In Memory (built-in and default)
Kafka (recommended for on-prem, production installations)

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

Kafka Installation

Apache Kafka is an open source stream processing platform.

To install Kafka in a Docker container, run the command below. It creates docker-compose-kafka.yml, fills it with configuration lines, and starts the container.
