System Full Reset

To reset the system, shut everything down, clear all the data in the Postgres and in Redis, and then restart everything.

Clearing:

• Stop Sending jobs to Sidekiq:

    clockworkd -c scripts/clock.rb --pid-dir=tmp/pids stop

• Stop Sidekiq:

    sidekiqctl stop tmp/pids/sidekiq.pid

• Stop apache (this will depend on your setup):

    apachectl -k stop

• Clear out Redis: (This is a dangerous but thorough way to do this. Be sure your Redis instance is not serving other purposes before doing this)

    redis-cli

In the redis shell:

    FLUSHDB

• Clear out the Postgres Database: (You might want to omit the "PointsConfiguration" data from deletion below.)

    rails c

In the rails console:

    [Activity, Assignment, Attachment, Comment, MediaUrl, PointsConfiguration, Student, View].each do |model| 
      model.delete_all
    end

Restarting:

• Restart apache (again, this depends on your setup)

    apachectl -k start

• Reseed the data (if you didn't omit PointsConfiguration above. But don't worry it will not overwrite any existing records):

    rake db:seed

• Restart sidekiq:

    mkdir -p /tmp/log
    mkdir -p /tmp/pids
    bundle exec sidekiq -d -L tmp/log/sidekiq.log -P tmp/pids/sidekiq.pid

• Restart clockworkd:

    clockworkd -c scripts/clock.rb --log-dir=tmp/log --pid-dir=tmp/pids -l start
