Run the Node.js application as a dedicated systemd service on a private loopback port, then let NGINX handle public HTTP, HTTPS, and reverse-proxy routing. This arrangement starts the app at boot, restarts it after failures, centralizes logs in the journal, keeps the Node listener off the public internet, and gives you one place to terminate TLS and forward client headers.

What the deployment looks like
The production path has three separate responsibilities:

- Node.js runs your application and listens on a local port such as
127.0.0.1:3000. - systemd starts that process during boot, owns its lifecycle, applies its restart policy, and records its output.
- NGINX is the public edge. It accepts requests on ports 80 and 443, terminates TLS, adds forwarding headers, and proxies traffic to Node.js.
A browser therefore never needs to connect directly to port 3000. Only NGINX needs access to the application listener. The exact service paths and package commands vary by Linux distribution, but the unit and proxy patterns are portable.
Prepare the server and application
Choose a stable application directory
Deploy the project somewhere that will not change between releases, such as /srv/myapp. Avoid running the production process from a developer home directory or a temporary checkout. Create a service account with no interactive shell:

sudo useradd --system --home /srv/myapp --shell /usr/sbin/nologin myapp
sudo install -d -o myapp -g myapp /srv/myappCopy the application into that directory and make the service account the owner. Keep deployment files, runtime files, and secrets separate where practical. The account only needs the permissions required to read the application and write the directories your app explicitly uses.
Install production dependencies
Use the Node.js version supported by the application and make sure the absolute executable path is known:
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemscommand -v node
node --version
npm --versionFor a project with a lockfile, install only production dependencies as the service account:
sudo -u myapp -- sh -c 'cd /srv/myapp && npm ci --omit=dev'If your application uses a compiled step, run that step during deployment and verify that the resulting entry point exists. Do not assume that node is at /usr/bin/node; use the path returned by command -v node in the unit file.
Make the app listen privately
Configure the server to read its port from the environment and bind to loopback. For example, the application may use PORT=3000 and listen on 127.0.0.1. Binding to 0.0.0.0 exposes the process on every network interface and defeats the isolation provided by NGINX unless your firewall explicitly prevents access.
Create the systemd service
Write the unit file
Create /etc/systemd/system/myapp.service as root. This example assumes the entry point is /srv/myapp/server.js; change it to your real file or package-script command.

WantedBy=multi-user.targetAfter=network.target orders startup after basic networking. User and Group prevent the application from running as root. WorkingDirectory makes relative paths predictable. ExecStart must contain an absolute Node executable and the actual application entry point. Restart=on-failure asks systemd to restart an unclean exit without repeatedly restarting a process that stopped successfully.
The optional environment file is useful for values that should not be embedded in the unit:
sudo install -d -m 0750 -o root -g myapp /etc/myapp
sudo sh -c 'cat > /etc/myapp/myapp.env' <<'EOF'
DATABASE_URL=postgres://user:[email protected]:5432/app
SESSION_SECRET=replace-with-a-long-random-value
EOF
sudo chmod 0640 /etc/myapp/myapp.envUse your secret-management process instead of placing credentials in shell history or source control. The leading hyphen in EnvironmentFile=-... means the unit can still start if that file is absent; remove the hyphen when the file is mandatory so a missing configuration fails loudly.
Load, enable, and inspect the service
- Ask systemd to reread unit files:
sudo systemctl daemon-reload. - Enable startup at boot and start immediately:
sudo systemctl enable --now myapp.service. - Check the current state and recent failure reason:
sudo systemctl status myapp.service. - Read application output and restart history:
sudo journalctl -u myapp.service. - Follow new log entries while testing:
sudo journalctl -u myapp.service -f.
If the service fails immediately, inspect the absolute path in ExecStart, the working directory, ownership of the entry point, required environment variables, and the port reported in the journal. A successful systemctl enable only creates the boot relationship; it does not prove that the application itself can start.
Put NGINX in front of Node.js
Define the local upstream and proxy headers
Create an NGINX site configuration appropriate for your distribution. The upstream name keeps the backend address in one place:
upstream node_backend {
server 127.0.0.1:3000;
}
server {
listen 80;
listen [::]:80;
server_name app.example.com;
location / {
proxy_pass http://node_backend;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}Replace app.example.com with the hostname that resolves to the server. Host preserves the requested hostname for virtual-host routing. The other headers let the application determine the original client address and whether the client used HTTP or HTTPS. Configure the framework to trust the proxy only according to its documented proxy setting; otherwise an application may accept forwarded values from untrusted clients.

Enable the site and test configuration
On distributions that use a sites-enabled directory, link the site into that directory; on others, include the file from the main NGINX configuration. Then test before every reload:
sudo nginx -t
sudo nginx -s reloadUse service nginx reload instead if that is the service command provided by your distribution. Do not reload after a failed syntax test. A reload applies a valid configuration to new workers while existing connections finish under the old workers.

Configure the TLS server
You need a certificate and matching private key issued by the certificate authority or managed certificate service you selected. Store the files with permissions that allow NGINX to read the key but do not make it broadly readable. Add a TLS server block:
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name app.example.com;
ssl_certificate /etc/letsencrypt/live/app.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/app.example.com/privkey.pem;
location / {
proxy_pass http://node_backend;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}The certificate paths above are an example layout; use the paths supplied by your certificate installation. A certificate without its private key, an unreadable key, or a hostname mismatch will prevent NGINX from starting or cause browser warnings.
Redirect port 80
Once the TLS block works, make the port-80 server redirect rather than proxying plaintext requests:
server {
listen 80;
listen [::]:80;
server_name app.example.com;
return 301 https://$host$request_uri;
}Keep the port-80 listener available if your certificate-renewal method needs an HTTP challenge. Confirm that DNS points the hostname to this server and that the firewall permits inbound TCP ports 80 and 443.

Proxy WebSockets correctly
WebSocket upgrade headers are hop-by-hop headers; NGINX does not forward them automatically. Put the upgrade settings in the location that serves the WebSocket endpoint, such as /ws/:
location /ws/ {
proxy_pass http://node_backend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}Use the same WebSocket location in the TLS server block. Keep ordinary HTTP routes in a separate location if they do not need upgrade behavior. If the socket connects locally but fails through NGINX, inspect the location path, the upstream port, the HTTP version, and both upgrade headers before changing application code.
Deploy updates without losing control of the process
- Place the new release in the application directory or a new release directory owned by the service account.
- Install the lockfile-defined production dependencies and run the required build step.
- Check configuration and file permissions before stopping the old process.
- Restart the service with
sudo systemctl restart myapp.service. - Immediately inspect
sudo systemctl status myapp.serviceandsudo journalctl -u myapp.service -n 100. - Test the backend locally and then through the public hostname.
For a configuration-only NGINX change, use nginx -t followed by a reload rather than a full stop and start. A restart of the Node service is appropriate when application code, dependencies, or environment values changed.
Implement graceful shutdown in Node.js
When systemd stops or restarts the service, Node.js receives a POSIX signal such as SIGTERM. Register a handler that stops accepting new connections, closes the server, and exits after cleanup. A minimal HTTP example is:
Free tools Windows power users keep installed
One-click scans. No signup required.
const http = require('node:http');
const app = require('./app');
const server = http.createServer(app);
const port = Number(process.env.PORT || 3000);
server.listen(port, '127.0.0.1');
function shutdown(signal) {
console.log(`${signal} received; closing server`);
server.close((error) => {
if (error) {
console.error(error);
process.exit(1);
}
process.exit(0);
});
}
process.on('SIGTERM', () => shutdown('SIGTERM'));
process.on('SIGINT', () => shutdown('SIGINT'));Add cleanup for database pools, queues, and other resources in the callback used by your framework. Keep the timeout in the unit long enough for normal requests to finish, but do not allow shutdown to hang indefinitely.
An uncaught exception leaves the process in an undefined state. Node.js documentation recommends an external monitor in a separate process to detect failure and restart the application rather than trying to continue inside the damaged process. In this architecture, systemd supplies that external supervision through the unit’s restart policy; fix the underlying exception instead of treating automatic restarts as a substitute for error handling.

Diagnose the common failure modes
| Symptom | Likely cause | What to check |
|---|---|---|
systemctl status shows a rapid restart loop |
Bad entry-point path, missing environment variable, permission error, or application crash | Read journalctl -u myapp.service; run the same absolute command as the service account; verify the working directory and secrets file. |
| NGINX returns 502 Bad Gateway | Node is stopped, listening on a different address or port, or blocked by a local permission/network rule | Check service status, then run curl http://127.0.0.1:3000/ on the server and compare the result with the proxy_pass target. |
| Requests reach Node but redirects or secure-cookie logic are wrong | The application is not receiving the original scheme | Confirm X-Forwarded-Proto $scheme and configure the framework’s trusted-proxy option appropriately. |
| WebSocket handshake fails | Upgrade headers are missing, the location does not match the socket path, or the upstream is wrong | Verify proxy_http_version 1.1, Upgrade, Connection, and the endpoint path in NGINX logs. |
| HTTPS will not load | Certificate path, key permissions, DNS, or firewall problem | Run nginx -t, verify both certificate files, confirm the hostname resolves to the server, and allow TCP 443. |
| Changes are not visible | The edited file was not included, or a daemon reload/restart was omitted | Use nginx -T to inspect the active configuration, systemctl daemon-reload after unit edits, and reload or restart the affected service. |
When isolating a problem, test from the inside out: first the Node listener with curl, then NGINX locally, then the public DNS name over HTTP or HTTPS. This separates application, proxy, and network errors instead of changing all three layers at once.
Run multiple Node.js instances
Use an NGINX upstream group
For more than one application process, give each instance a different local port and list them in the upstream:

server 127.0.0.1:3002;
}Keep the same proxy_pass http://node_backend; in the server block. NGINX Open Source uses round-robin distribution by default. Each instance needs its own process definition or an instance template, and every process must share access to required configuration and application assets.
Account for state and failure behavior
Multiple instances change the design questions. In-memory sessions and local-only uploads can send a user to a different process on the next request; use a shared session store or another state strategy when the application requires it. WebSocket clients also need a plan for reconnects and, where appropriate, shared pub/sub state. NGINX Open Source provides basic upstream distribution, while NGINX Plus adds advanced health checks, monitoring, session persistence, and dynamic upstream reconfiguration. Choose the simpler direct proxy for one instance; introduce an upstream group only when the application and operations process can support the extra failure and state considerations.
Production checklist
- The Node process runs under a dedicated non-root account.
- The application binds to a private loopback address when NGINX is the only public entry point.
- The unit specifies an absolute executable, working directory, environment, restart policy, and boot target.
systemctl daemon-reloadis run after unit changes, and the service is enabled withsystemctl enable --now.- NGINX forwards the host, client address, forwarding chain, and original scheme.
- HTTPS uses a valid certificate and matching private key, with HTTP redirected to HTTPS.
- WebSocket locations explicitly forward HTTP/1.1 upgrade headers.
nginx -tsucceeds before every reload.- Ports 80 and 443 are allowed through the firewall, while the Node port is not publicly exposed.
- Logs are checked in both the systemd journal and NGINX access/error logs.
- The application handles SIGTERM and closes resources cleanly.
With these pieces in place, systemd owns reliable process startup and recovery, while NGINX provides the controlled public boundary. The Node.js application can remain a private local service, and each layer can be tested independently when a deployment fails.
