@Alexey @jammerdan is there a way to autostart the ./multinode with system startup? So I don´t have to enter "nohup ./multinode run & " each startup? Unfortunately the multinode isn´t listed on the systemctl list. Thanks in Advance 
Sure it is possible. How to do it depends on what OS in general and what Linux in particular you are on.
Here is a general description for a Debian OS: systemd/Services - Debian Wiki
