Nodejs

CloudPanel v1 is obsolete

CloudPanel v1 is obsolete; check out the CloudPanel v2 Docs.

On this page, we explain step by step how to setup a Nodejs App with CloudPanel.

Installation

In the following example, we will setup a Nodejs under the domain www.domain.com.

Preparation

Before we can start with the installation, we need to create an SSH User and a Domain.

When you Add the Domain, make sure to select the Nodejs Vhost Template.



Application Port

By default, all requests are forwarded to port 3000 via reverse proxy.

If your Nodejs App is running under another port, you can change it easily in the Vhost Editor of your domain.

Production Deployment

For running a NodeJs App in production it's recommended to use a process control system like supervisor, which restarts the node processes automatically in case of a failure.

Setup Supervisor

  1. Install the supervisor package:
apt update && apt -y install supervisor
  1. Create a supervisor configuration file:
touch /etc/supervisor/conf.d/nodejs-app.conf
  1. Open the configuration file and put the following content:
[program:nodejs-app]
process_name=%(program_name)s_%(process_num)02d
command=/usr/bin/node /home/cloudpanel/htdocs/www.domain.com/app.js
numprocs=1
user=john-ssh
autostart=true
autorestart=true
stopsignal=KILL
stdout_logfile=/var/log/supervisor/nodejs-app.log
Attention

Make sure that the user is correct to avoid permission problems.

  1. Update the configuration and start the node processes:
supervisorctl reread
supervisorctl update
supervisorctl start nodejs-app:*

With the command supervisorctl you get information about the status, pid, and uptime:

Troubleshooting

You may want to see what happens in the background; you can do that by tailing the log file:

tail -f /var/log/supervisor/nodejs-app.log -n1000
