Datacamp is a Web application for publishing, searching and managing data in form of datasets.

bin/setup
foreman start

This project uses environment variables for configuration. See the .env file to see what is available. If you need to override some variable for development and that change is specific to your machine and should not concern other developers, create a .env.local file and add the variable there. .env.local is gitignored by default.

1. Provision a server using the provided ansible scripts.

2. On the server, set up application environment in .bashrc. Start by copying all variables from .env and change them as needed. It is important that

   • the variables are exported to subprocesses, i.e., (unlike in .env) start each line with export. For example export DATANEST_MYSQL_PASSWORD=pass.

   • the exports are placed at the very top of the .bashrc file, before the check that skips loading the rest of the file in non-interactive session (that means both capistrano and passenger)

     # ~/.bashrc: executed by bash(1) for non-login shells.
     # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
     # for examples
     
     export DATANEST_MYSQL_HOST=localhost
     export DATANEST_MYSQL_PORT=3306
     # [more exports ...]
     
     # If not running interactively, don't do anything
     case $- in
         *i*) ;;
           *) return;;
     esac
     
     # [rest of the .bashrc]

3. For the first time, run cap production deploy:cold. This will create databases and import schemas. This should only be called once and in the first deploy. Otherwise run cap production deploy.

4. Optionally, to import database dumps, first download them on your development machine and run cap production deploy:import_dump DUMP=path/to/datanest_data_dump.sql.gz. The file will be gzipped automatically if not already. Make sure that the dump name start with datanest_$DB as the name format is used to extract the database name.

Thinking sphinx server is automatically started (and reindexed) on deploy if it is not running already. If you need to change configuration or restart the server, do so manually via the thinking_sphinx capistrano tasks. Run cap -T thinking_sphinx to see what is available. Note that sphinx will be automatically stoped and started again for things like reindexing or reconfiguration, causing a brief search downtime.

Sphinx indices are rebuilt periodically in a cron job defined in config/schedule.rb (causing a search downtime).
