add instructions on how to start server on system startup

[boris-horner]

I can add to that - I wrote some docs that do the job - needs to be adapted, is related to the VM I installed to which was Ubuntu 22.04...

Create and test startup script

• Create Cinnamon 4 startup script:
  • Create a file /opt/cinnamon/runc4.sh with the following content:

    #!/bin/bash
    export JAVA_HOME=/opt/jdk-17.0.2
    export PATH=$PATH:$JAVA_HOME/bin
    cd /opt/cinnamon
    java -jar cinnamon-server.jar --config cinnamon-config.xml

  • Set the file to be executable by the owner.
• Execute /opt/cinnamon/runc4.sh.
• Use a browser or curl to access http://localhost:8080/cinnamon.

  NOTE: You should see a response like this: Cinnamon 4 Server

Set up Cinnamon service

• Create a file /etc/systemd/system/cinnamon.service.
• Copy the following content into the file:

  
  [Unit]
  Description=Cinnamon Server
  After=postgresql

[Service] User=root ;Group=groupname WorkingDirectory=/opt/cinnamon ExecStart=/opt/cinnamon/runc4.sh Environment="JAVA_HOME=/opt/jdk-17.0.2" Environment="PATH=$PATH:$JAVA_HOME/bin"

[Install] WantedBy=multi-user.target

* Load the service unit and enable and start the service:

systemctl daemon-reload systemctl enable cinnamon.service systemctl start cinnamon.service
