Запуск node.js сервера как службы

Создаем в /etc/systemd/system/nodeserver.service

[Unit]
Description=My node Server

[Service]
# set the working directory to have consistent relative paths
WorkingDirectory=/var/www/app

# start the server file (file is relative to WorkingDirectory here)
ExecStart=/home/user/.nvm/versions/node/v14.15.3/bin/node ./src/index.js
# if process crashes, always try to restart
Restart=always

# let 500ms between the crash and the restart
RestartSec=500ms

# send log tot syslog here (it doesn't compete with other log config in the app itself)
StandardOutput=syslog
StandardError=syslog

# nodejs process name in syslog
SyslogIdentifier=nodejs

# user and group starting the app
User=www-data
Group=www-data

# set the environement (dev, prod…)
Environment=NODE_ENV=production

[Install]
# start node at multi user system level (= sysVinit runlevel 3) 
WantedBy=multi-user.target

Теперь можно запускать, останавливать и перезапускать приложение с помощью:

service nodeserver start
service nodeserver stop
service nodeserver restart

Чтобы сообщить systemd автоматически запускать узел при загрузке, просто введите:

systemctl enable nodeserver
