Manage Node.js applications with PM2 from Plesk, with admin, reseller, and customer scoped access.

Node Manager (PM2) is a Plesk extension for managing Node.js applications with PM2 without SSH.

It is built for hosting panels where admins need a clean process manager for SSR apps, API servers, queues, websocket servers, and other long-running Node.js services while keeping customers scoped to their own subscriptions.

Install the latest runner-built package directly from GitHub:

plesk bin extension --install-url https://github.com/ghostcompiler/node-manager-pm2/releases/download/latest/node-manager-pm2.zip

This URL points to the rolling latest release asset. The Package Latest workflow rebuilds node-manager-pm2.zip from the current main branch on every push and whenever it is started manually, so the install command stays stable and does not depend on a hardcoded version number.

Pinned version installs are also available after publishing a versioned release:

plesk bin extension --install-url https://github.com/ghostcompiler/node-manager-pm2/releases/download/v1.0.0/node-manager-pm2-1.0.0.zip

Build the extension ZIP locally:

./packaging/build.sh

Install the locally built archive through Plesk CLI:

plesk bin extension --install node-manager-pm2-1.0.0.zip

Or install through Plesk UI:

1. Open Plesk Admin.
2. Go to Extensions.
3. Click Upload Extension.
4. Upload node-manager-pm2-1.0.0.zip.
5. Open Node Manager (PM2) from the Plesk sidebar or a domain page.

Run the same local checks used by the CI runner:

npm ci --ignore-scripts --legacy-peer-deps
npm run build
find plib htdocs -type f \( -name '*.php' -o -name '*.phtml' \) -print0 | xargs -0 -n1 php -l
xmllint --noout meta.xml
node -e "JSON.parse(require('fs').readFileSync('packaging/manifest.json', 'utf8'))"
sh -n packaging/build.sh
sh -n sbin/pm2-helper
./packaging/build.sh
zip -T node-manager-pm2-1.0.0.zip

GitHub Actions runners are included:

• CI runs on every branch push, pull request, and manual dispatch. It validates PHP, JavaScript, documentation screenshots, metadata, shell scripts, builds the extension, tests the ZIP, and uploads package artifacts.
• Package Latest runs on main and manual dispatch. It builds and publishes the stable node-manager-pm2.zip asset to the rolling latest GitHub release.
• Release runs on v<version> tags and manual dispatch. It verifies the tag matches meta.xml, builds node-manager-pm2-<version>.zip, and publishes the versioned release.
• Pages runs when documentation changes on main and manual dispatch. It validates docs/index.html screenshot references and deploys the docs/ folder to GitHub Pages.

1. Open the affected service plan or subscription.
2. Enable Node Manager (PM2) access.
3. Enable the needed action permissions: control, logs, and manage.
4. Set Maximum PM2 applications to a non-zero value for subscriptions that can create processes.
5. Sync existing subscriptions if Plesk marks them as customized or out of sync.
6. Open Node Manager (PM2) as admin, reseller, or customer.
7. Review the Runtime tab and install PM2 if needed.

For a subdomain such as assets.example.com where the app root is:

/var/www/vhosts/example.com/assets.example.com

Use:

Name: assets-ssr
Script path: server.js
Working directory: .
Environment: production
Instances: 1
Autorestart: enabled

The extension resolves relative paths from the selected domain application root, so server.js becomes:

/var/www/vhosts/example.com/assets.example.com/server.js

When the UI reports a 500 error, check:

tail -n 200 /var/log/plesk/panel.log
tail -n 200 /var/log/sw-cp-server/error_log
tail -n 200 /usr/local/psa/var/modules/node-manager-pm2/logs/node-manager-pm2.log

On some Plesk builds, the panel log is stored at:

tail -n 200 /usr/local/psa/admin/logs/panel.log

• Admins can view and manage all enabled domains.
• Resellers and customers only see domains where Node Manager access is enabled.
• Customer and reseller access is controlled by Plesk service plan permissions.
• Process script and working-directory paths are locked inside the selected domain application root.
• PM2 commands run under the selected domain system user when Plesk pm_ApiCli::callDomain() is available.
• The extension stores PM2 metadata and secrets in SQLite under the Plesk module var directory.

• PHP classes live in plib/library/NodeManagerPm2.
• Authenticated UI and JSON APIs are served by plib/controllers/IndexController.php.
• The Plesk React UI Library bundle lives in frontend/ and is built to htdocs/dist/node-manager-pm2-ui.js.
• The public deployment webhook lives at htdocs/public/webhook.php.
• Persistent state is stored in SQLite under the module var directory.
• Package configuration lives in packaging/manifest.json and packaging/build.sh.
