Unable to start custom systemd service for Nodejs: Node not found

Question

I installed Rocket.chat on my Debian Jessie, it works well and I want to start it automatically at boot as a service.

To start Rocket.chat manually I need to

$ cd /home/hung/Rocket.chat
$ node main.js

This is my /etc/systemd/system/rocket-chat.service

[Service]
ExecStart=/usr/local/bin/node main.js
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocket-chat
User=hung
Group=hung
WorkingDirectory=/home/hung/Rocket.chat

[Install]
WantedBy=multi-user.target

The service doesn't start:

# systemctl start rocket-chat
# systemctl status rocket-chat
● rocket-chat.service
   Loaded: loaded (/etc/systemd/system/rocket-chat.service; disabled)

/usr/local/bin/node exists:

$ /usr/local/bin/node --version
v8.9.3

How do I solve the problem that /usr/local/bin/node is not found?

Answer 1

ExecStart should be

ExecStart=/usr/local/bin/node /home/hung/Rocket.chat/main.js

This is my final version of the file (/etc/systemd/system/rocketchat.service):

[Unit]
Description=RocketChat Server
After=network.target remote-fs.target nss-lookup.target mongod.target apache2.target

[Service]
ExecStart=/home/hung/.nvm/versions/node/v8.9.3/bin/node /var/www/chat/Rocket.Chat/main.js
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
Environment=NODE_ENV=production
Environment=PORT=3001
Environment=ROOT_URL=https://domain.com/
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat
Environment=MAIL_URL='smtp://user@domain:password@domain:587/'

[Install]
WantedBy=multi-user.target

Start the service: sudo systemctl start rocketchat

Start on boot: sudo systemctl enable rocketchat
