Automatically start a service or script after linux runs
There are several methods:
1. The easiest is to add a startup service or execute a script statement to the /etc/rc.d/rc.local file.
2. Add a script to control the service in the /etc/rc.d/init.d folder

A little trick: put the command into the background to run, it does not affect the execution of the script in the current window -> just add & after the command
E.g:
node app.js >> app.log &
echo "startup successful"
It means: execute the node app and save the printed content to the log file app.log, and the interface outputs "startup successful". (you can try without &)
The difference between >> and > : >> is to append the file content, > is to overwrite the file content
