Webcron Management

(c) 2017-2018, 2021- Jeroen De Meerleer me@jeroened.be

Webcron management is an easy-to-use interface to manage cronjobs running on a publicly available http-location.


Requirements for build-server

  • php <= 8.1 (incl composer <= 2, ext-pcntl, ext-openssl, ext-intl)
  • NodeJS <= 16.0 (incl. npm <= 8)


Please run following command on the build server

$ composer install --no-dev --optimize-autoloader
$ npm install
$ npm run build
$ rm -rf node_modules # Node modules are only required for building



  • php <= 8.1
    • ext-openssl
    • ext-intl
    • ext-pcntl (highly recommended)
  • MariaDB
  • SSH-access to the server
  • Ability to change the webroot directory
  • Ability to run a script as daemon (eg. supervisor or systemd units)


  1. Create a build yourself or download the build from the releases page

  2. Upload the build to the webserver.

  3. Set up your webhosting to use the /public directory as web root

  4. Create the .env file by copying .env.sample to .env and change the values

  5. Run php bin/console doctrine:migrations:migrate to create or migrate the database

  6. Create a first user by running php bin/console webcron:user add

  7. Set up the daemon script using systemd, supervisord or similar system

    If this is not possible running the daemon using a cronjob is still possible using below gist (Not recommended)

0 * * * * cd /path/to/webcron/ && php webcron daemon --time-limit=3600 > /dev/null 1&>2



Same requirements and deploying


  1. Remove all files except .env from the webserver
  2. Upload the new build to the webserver
  3. Run php bin/console doctrine:migrations:migrate to migrate the database

Common pitfalls

I can't do an automatic system upgrade!

Doing a system upgrade requires sudo which has a certain number security measurements. To enable running anything with sudo (eg. sudo apt dist-upgrade -y) the user needs to be able to run sudo without tty and password.
