Discourse

Add allianceauth.services.modules.discourse to your INSTALLED_APPS list and run migrations before continuing with this guide to ensure the service is installed.

Install Docker

wget -qO- https://get.docker.io/ | sh

Get docker permissions

sudo usermod -aG docker allianceserver

Logout, then back in for changes to take effect.

Install Discourse

Download Discourse

sudo mkdir /var/discourse
sudo git clone https://github.com/discourse/discourse_docker.git /var/discourse

Configure

cd /var/discourse
sudo cp samples/standalone.yml containers/app.yml
sudo nano containers/app.yml

Change the following:

• DISCOURSE_DEVELOPER_EMAILS should be a list of admin account email addresses separated by commas
• DISCOUSE_HOSTNAME should be 127.0.0.1
• Everything with SMTP depends on your mail settings. Account created through auth do not require email validation, so to ignore everything email (NOT RECOMMENDED), just change the SMTP address to something random so it'll install. Note that not setting up email means any password resets emails won't be sent, and auth cannot reset these. There are plenty of free email services online recommended by Discourse.

To install behind apache, look for this secion:

...
## which TCP/IP ports should this container expose?
expose:
  - "80:80"   # fwd host port 80   to container port 80 (http)
...

Change it to this:

...
## which TCP/IP ports should this container expose?
expose:
  - "7890:80"   # fwd host port 7890   to container port 80 (http)
...

Or any other port will do, if taken. Remember this number.

Build and launch

sudo nano /etc/default/docker

Uncomment this line:

DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

Restart docker:

sudo service docker restart

Now build:

sudo ./launcher bootstrap app
sudo ./launcher start app

Apache config

Discourse must run on its own subdomain - it can't handle routing behind an alias like '/forums'. To do so, make a new apache config:

sudo nano /etc/apache2/sites-available/discourse.conf

And enter the following, changing the port if you used a different number:

<VirtualHost *:80>
    ServerName discourse.example.com
    ProxyPass / http://0.0.0.0:7890/
    ProxyPassReverse / http://0.0.0.0:7890/
</VirtualHost>

Now enable proxies and restart apache:

sudo a2enmod proxy_http
sudo service apache2 reload

Configure API

Generate admin account

From the /var/discourse folder,

./launcher enter app
rake admin:create

Follow prompts, being sure to answer y when asked to allow admin privileges.

Create API key

Navigate to discourse.example.com and log on. Top right press the 3 lines and select Admin. Go to API tab and press Generate Master API Key.

Now go to the allianceauth folder and edit settings:

nano /home/allianceserver/allianceauth/alliance_auth/settings.py

Scroll down to the Discourse section and set the following:

• DISCOURSE_URL: discourse.example.com
• DISCOURSE_API_USERNAME: the username of the admin account you generated the API key with
• DISCOURSE_API_KEY: the key you just generated

Configure SSO

Navigate to discourse.example.com and log in. Back to the admin site, scroll down to find SSO settings and set the following:

• enable_sso: True
• sso_url: http://example.com/discourse/sso
• sso_secret: some secure key

Save, now change settings.py and add the following:

• DISCOURSE_SSO_SECRET: the secure key you just set

Enable for your members

Set either or both of ENABLE_AUTH_DISCOURSE and ENABLE_BLUE_DISCOURSE in settings.py for your members to gain access. Save and exit with control+o, enter, control+x.

Done
