Managing the server

manage.py commands

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws help

• create a new user -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws create_user -e [email protected]

• set or change password -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws changepassword user

• set user to staff -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws set_staff [email protected]

• launch the django shell -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws shell

• create superuser -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws create_user -e [email protected]
  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws changepassword user
  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms --settings aws shell
  
  from django.contrib.auth.models import User
  me = User.objects.get(username="user")
  me.is_superuser = True
  me.save()
  

• run migrations -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py lms syncdb --migrate --settings aws

• delete course -

  sudo -u www-data /edx/bin/python.edxapp ./manage.py　cms --settings aws delete_course Organization/CourseNumber/CourseNumber commit

See help and help <cmd> for more information!

See what services are running

sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf status

you should see something like the following:

Restarting Services

• LMS/CMS - sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf restart edxapp:
• Workers - sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf restart edxapp_worker:

(Note: the colon character : at the end of the line is mandatory!)

Updating Versions using edX repos

Use the /edx/bin/update to update repo versions on the server.

Allowed repo names [cs_comments_service,ease,discern,xqueue,xserver,edx-platform,configuration,edx-ora]

Examples:

• sudo /edx/bin/update edx-platform master - change edx-platform to use the latest on the master branch
• sudo /edx/bin/update cs_comments_service master - change the forums service to use the latest on the master branch

Using an edx-platform fork

• sudo rm -rf /edx/app/edxapp/edx-platform - to change the remote you need to remove the existing edx-platform checkout
• Add the following line to /edx/app/edx_ansible/server-vars.yml - edx_platform_repo: "https://github.com/<user>/edx-platform.git"
• sudo /edx/bin/update edx-platform master - update edx-platform using the forked repo

Compile assets manually

To compile javascript and css outside of the update script run the following commands:

• sudo -u edxapp bash
• source /edx/app/edxapp/edxapp_env
• cd /edx/app/edxapp/edx-platform
• SERVICE_VARIANT=lms rake lms:gather_assets:aws
• SERVICE_VARIANT=cms rake cms:gather_assets:aws

Troubleshooting

Unable to connect to the LMS

Check to see if nginx is running:

• sudo service nginx status
• sudo service nginx start

NGINX logs are located in /edx/var/log/nginx NGINX configurations are located in /edx/app/nginx/sites-enabled

Check to see if the lms/cms is running

• sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf status edxapp:

If you are still unable to connect to the LMS run the following commands:

• sudo service nginx stop
• sudo service supervisor stop
• sudo service supervisor.devpi stop
• sudo pkill -u www-data
• sudo service nginx start
• sudo service supervisor start
• sudo service supervisor.devpi start
• stop everything except the LMS and CMS

sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf stop discern discern_celery \
  forum ora ora_celery xqueue xqueue_consumer xserver edxapp_worker:

• sudo tail -f /edx/var/log/{lms,cms,nginx}/*log

While tailing the log files try to connect your browser to the LMS or Studio

Log files

• The production stack sends all application logs to rsyslog which writes config files to the /edx/var/log directory.
• Supervisor logs stderr and stdout, its logs are located in /edx/var/log/supervisor
