Installing the Talend Runtime service on systemd-based Linux systems

Before you begin

In the following procedure:

TALEND-CONTAINER is the name that was used for the -n <Service Name> option in the wrapper:install command.
<TalendRuntimePath> is the Talend Runtime installation directory.

All the following commands must be executed with super-user privileges.

Install the service and enable it at system boot:
```
systemctl enable <TalendRuntimePath>/bin/TALEND-CONTAINER.service
```
Troubleshooting:
If the systemctl enable command fails with the error Failed to enable unit: Cannot alias ..., follow these steps:
1. Open the [TALEND_RUNTIME_PATH]/bin/TALEND-CONTAINER.service file in a text editor.
2. Locate the line starting with Alias= and delete it.
3. Save the changes.
4. Execute the systemctl daemon-reload command.
After completing these steps, the systemctl enable command should work as expected.
Start the service:
systemctl start TALEND-CONTAINER
To ensure the systemd service starts correctly, stop any Talend Runtime container that was previously launched using the trun command. Otherwise, systemd may attempt to start a second instance of Talend Runtime, which will fail because the TCP/IP ports are already in use.

The service is installed and started.

You can use the following commands to manage the service:

To stop the service: systemctl stop TALEND-CONTAINER
To check the current service status: systemctl status TALEND-CONTAINER
To see service activity journal: journalctl -u TALEND-CONTAINER
To uninstall the service and disable it at system boot: systemctl disable TALEND-CONTAINER
