Supports: precise
Add to new model


This will install and setup Metis to run on your Apache or Nginx server.


Metis is an open source and highly robust JSON distributed database / storage solution. This charm will install Metis in /var/www/Metis.

Installation / Deploying


To deploy this charm, you will need at least: an http server (whether it be apache or nginx) that has access to executing PHP, a working Juju installation and a successful bootstrap.

Initial Configuration

By default, Metis will download / check for dependencies relating to nginx. If you are wanting to deploy Metis on an apache server, modify the config.yaml engine to "apache2".


Once bootstrapped and you have modified the configuration if necessary, deploy the Metis charm by doing: juju deploy metis

When you deploy Metis, it will:

  • Check if nginx or apache2 is installed. If not, it will automatically download nginx.
  • Check if the necessary PHP libraries are installed (primarily php5 and php5 CURL). If not, it will automatically download those dependencies.
  • Download the latest Metis version from as well as it's dependency AtlasUI Web Framework ( and install those in /var/www/AtlasUI and /var/www/Metis.

Detailed Configuration

Before exposing Metis, you will need to modify the nodeList.json file in /var/www/Metis as well as create the necessary folders in /var/www/Metis/data. You can read more about setting up Metis at

Exposing Metis

After you have modified the nodeList.json file and created the necessary folders within /var/www/Metis/data/, you are welcome to expose the Metis service by doing the following: juju expose metis

All done! You've now deployed Metis on your juju system
