Installing and uninstalling Remote Engine service (System V)

Talend Remote Engine is based on Apache Karaf. Karaf Service Wrapper makes it possible to install the Remote Engine as a Linux service.

Procedure

Stop the engine if it is running.
If your engine is running tasks, you can follow this procedure to gracefully shut down Talend Remote Engine.
Open a terminal instance.
Browse to the bin folder of the Talend Remote Engine installation directory and run the following command to create OS service wrapper files for the talend-remote-engine service.
```
./shell wrapper:install -n talend-remote-engine
```
The following files are created in the <RemoteEngineInstallationDirectory>/bin folder:
- talend-remote-engine-wrapper
- talend-remote-engine-service
- talend-remote-engine.service
The talend-remote-engine-wrapper.conf file is created in the <RemoteEngineInstallationDirectory>/etc folder. In this wrapper configuration file, you can customize the JVM properties for the engine service.

Browse to the bin folder of the Remote Engine installation directory, then run the following commands to install the talend-remote-engine service:

For Ubuntu/Debian:

ln -s <RemoteEngineInstallationDirectory>/bin/Talend-Remote-Engine-service /etc/init.d/
