there is an online node project, and after installing a restart of the forever, server, the node project will not start properly.
the startup process using forever is as follows:
$forever start /var/www/html/nipt/niptWeb/bin/www
Service Unavailable
npm start :
the URL is opened at this time and can be accessed normally, but after the Ctrl+C background exits, the web page prompts Service Unavailable
what is the reason why the forever directive fails to start the project?
