Installing on Amazon Web Services¶
To make it easier for you to get an OppiaMobile server up and running, we have created an Amazon Web Services machine image that you can copy and comes pre-packaged with the latest version of the OppiaMobile Server so will run ‘out of the box’.
Launch an AWS Machine Image¶
Once you have created your account on AWS:
- Go into your instances page
- Select ‘launch instance’
- Select ‘Community AMIs’
- Search for ‘oppia’ and you should see the most recent version of the OppiaMobile AMI listed
- Launch your new instance - you can alter the instance configuration (security groups etc) during the rest of the launch instance process.
When you search the OppiaMobile server AMI will only appear in the search results if you have selected the ‘EU (Ireland)’ zone
Once your instance is up and running you will be able to assign a static IP, access via your web browser and log into the server using the IP address.
It is beyond the scope of this guide to give the full information about how to connect and configure your AWS account instances.
You can point your domain name
Access via SSH¶
It is strongly recommended that you only allow access to your Oppia server using SSH (HTTPS). Certbot is already installed on the server, so you can use this to set up free SSH certificates. For more info see: https://certbot.eff.org/lets-encrypt/ubuntubionic-apache (start from step 7)
When you install and launch your instance it is set up with a default set of usernames/passwords:
- MySQL root password: ‘default’
- MySQL oppia user password: ‘default’ - this is the user that Django uses to
connect to your database. When you have changed this password you should also
update the settings file (at:
/home/oppiamobile/django-oppia/oppiamobile/settings_secret.py) to reflect the new database password.
- Django super user: username ‘admin’ and password ‘default’
You are very strongly advised to change these passwords as soon as you have set up your instance
Directories and location of files¶
All the required files are stored in the /home/oppia/ directory, which has the following structure:
- django-oppia (dir): the OppiaMobile server application files
- env (dir): root of the virtualenv
- media (dir): the media directory for Django (this directory served directly by Apache)
- oppia-cron.sh (file): a shell script for running the OppiaMobile cron task - it’s unlikely you’ll ever need to do anything with this file.
- static (dir): the static directory for Django (this directory is served directly by Apache)
- upload (dir): stores the course uploads
In the main django settings, the server is set to run in debug mode. This will be fine when you are testing, but once you are ready to start providing the server live, you should change this setting to DEBUG=False
Updating django-oppia server code from core¶
The code is based on a ‘point-in-time’ version of the OppiaMobile server code, so once you have set up your instance, you should try to keep it up to date.
Creating your own version of django-oppia¶
If you have created your own fork of django-oppia (for example to customise the
look and feel), then you can point git to the fork of your code by editing the
/home/oppiamobile/django-oppia/.git/config file and pulling the code from
your fork instead.
The current version of the instance is running:
- OppiaServer 0.12.16
- Ubuntu 18.04 LTS Server
- Apache 2.4
- Mysql 5.7
- Django 2.2.20
- TastyPie 0.14.2
By default your AWS Oppia server is not configured to send email, any
emails generated by the system (for example reset password messages) are just
saved as plain text files in the
To enable sending email you will need to:
- configure your AWS account to enable email sending (using SES service)
- create/download your AWS IAM Access Key
- update the
/home/oppiamobile/django-oppia/oppiamobile/settings_secret.pyfile to configure sending email
settings_secret.py file should have a block of code like this (just
add in your access key and secret access key):
# Email setup EMAIL_HOST = 'email-smtp.eu-west-1.amazonaws.com' EMAIL_PORT = 587 EMAIL_HOST_USER = '<IAM Access User>' EMAIL_HOST_PASSWORD = '<IAM Access password>' EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = '<email to send from>'
