Install Relution on AlmaLinux


Make sure your system is up-to-date.

sudo yum -y update
During this installation some files will need to be edited manually. If you are familiar with vim set it as default editor with the commands below. If you are not familiar with vim please skip this and keep using the default editor.
sudo yum -y install vim
sudo update-alternatives --install /usr/bin/editor editor /usr/bin/vim 100

Install dependencies

Install the required packages, including Java.

We currently recommend the use of OpenJDK 11 (JRE). Most vendors treat this version as a long term support (LTS) release. Make sure to read our change log for the most up-to-date information.
sudo yum -y install java-11-openjdk unzip wget

Configure Java home

echo "export JAVA_HOME=/usr" | sudo tee -a /etc/profile.d/
source /etc/profile

Verify the changes have taken effect.


You should see the configured path (/usr).

Create a Relution user

Create an unprivileged user to be used by the Relution service.

sudo useradd -s /usr/bin/false -r relution

This creates an unprivileged user with the name relution that will be used to run the Relution service. This is done for security reasons since running services with root privileges is not recommended.

Download Relution

Download and extract the latest Relution package.

sudo wget --directory-prefix=/opt
sudo unzip /opt/ -d /opt

Change owner of the relution directory:

sudo chown -R relution:relution /opt/relution

Basic Relution configuration

Change to /opt/relution:

cd /opt/relution

Download Relution configuration file:

sudo wget

Edit the application.yml.template which is stored at /opt/relution and adjust it to your environment. All values that must be replaced have placeholders in the form of %VALUE%, for example %MYSQL_PASSWORD%. You must at least replace the following values:

Placeholder Description


The external URL of your Relution server, e.g.


The password of the relution database user


The hostname of your SMTP server


The port of your SMTP server (default: 25)


The username of a user on the SMTP server


The password of a user on the SMTP server


The initial password of the system administrator. Change this after first sign in


The system administrator’s email address


The unique name of the initial Relution organization to create. Must only contain alphanumeric characters and no blanks.


The name of the initial Relution organization to create


The username of the organization administrator. Must only contain alphanumeric characters and no blanks.


The initial password of the organization administrator. Change this after first sign in


The name of the organization administrator


The family name of the organization administrator

Consider the use of pwgen to generate the initial password for your administrative account. We recommend to change the password after you sign in for the first time.

Move the file to the Relution server’s installation directory:

sudo mv application.yml.template /opt/relution/application.yml

Make sure only root can edit this file and allow relution to read it.

sudo chown root:relution /opt/relution/application.yml
sudo chmod 640 /opt/relution/application.yml

Verify installation

To verify that setup until this point is correct, start the Relution service in the foreground.

cd /opt/relution
sudo -u relution JAVA_HOME=/usr bin/

Wait for the Relution service to start up. Once the terminal output has stopped moving you should be able to connect to the service with a browser. To connect from a remote machine, make sure port 8080 is open in the machine’s firewall. For security reasons you should close this port once the service has been configured. Users will connect to the service using ports 80/443 served by nginx.


To temporarily allow connections on port 8080 until the next server reboot:

sudo firewall-cmd --zone=public --add-port=8080/tcp

If everything is working, you should see the Relution portal and you can log in with the administrative account configured in the application.yml. For security reasons you should change the password of the administrator after you sign in. Consider removing the initial organization and administrator configuration from the application.yml for security reasons.

If you receive errors, verify that you completed all steps above. Use Ctrl+C to stop the service and wait for the service to shut down. If the service does not stop, use Ctrl+C again to force it to stop.

Create systemd service file

To start Relution as a system service, create a systemd service file for Relution. You can download the file from our GitHub repository.

sudo wget

Move the file to the systemd directory

sudo mv relution.service.template /etc/systemd/system/relution.service

Reload the systemd daemon to pick up the new service.

sudo systemctl daemon-reload

Make sure Relution’s directories are still accessible to the service. If the application was previously started as root it may otherwise be unable to write to its log file or temp directory.

sudo chown -R relution:relution /opt/relution
sudo chown -R relution:relution /tmp/relution.tmp

Start Relution and make sure the service is started automatically after a system reboot.

sudo systemctl start relution
sudo systemctl enable relution

To monitor the service’s startup you can follow its log file (Press Ctrl+C to exit).

tail -f /opt/relution/log/relution.log

Wait for the Relution service to start up. You should once again be able to connect to the service with a browser.


It is also a good idea to close the firewall port that was opened for testing at this point. Otherwise the port will remain open until the next system reboot. If nginx will be installed on another machine you can skip this step and continue with the firewall configuration below.

sudo firewall-cmd --zone=public --remove-port=8080/tcp

Firewall configuration

If you install nginx on another machine, you need to permanently open port 8080 on this machine, so nginx can talk to Relution. If nginx is going to be installed on the same machine you can skip these steps.

Replace ADDRESS with the IP address and netmask of the machine or network you want to grant access to this Relution instance. Examples: Use to grant access to the machine with the IP address Use to grant access to any machine in the IP address range 192.168.0.x. When in doubt, consult your network administrator.
sudo firewall-cmd --permanent --zone=public --add-rich-rule='rule family="ipv4" source address="###ADDRESS###" port protocol="tcp" port="8080" accept'
sudo firewall-cmd --reload
