Tutorial: Run Discourse on Liquid Web?

10 minutes read

Running Discourse on Liquid Web is a relatively simple process that can be done by following a step-by-step tutorial. Discourse is an open-source platform designed for creating online communities and discussion boards.


To begin, you will need to have a Liquid Web account and a server set up. The tutorial will guide you through the process of setting up a server with Liquid Web's Managed WordPress offering and installing Discourse on that server.


Once the server is set up, the tutorial will walk you through the process of installing Docker, which is a platform used for running applications in containers. Discourse requires Docker to work efficiently.


After Docker is set up, you will need to clone the Discourse repository from GitHub. This will involve using command-line tools and running specific commands to download the necessary files.


Next, you will need to configure Discourse by editing the app.yml file. This file contains important settings such as the hostname, email address, database information, and other configuration options. The tutorial will guide you on how to modify this file correctly.


Once the configuration is complete, you can use Docker to build and start the Discourse container. This will initiate the installation process and set up Discourse on your Liquid Web server.


The tutorial will also cover important topics such as securing your Discourse installation, setting up SSL certificates, and configuring email settings to enable features like user registration and password reset.


Throughout the tutorial, there will be detailed explanations and examples to help you understand the process and troubleshoot any issues that may arise. Following this tutorial will ensure that you can successfully run Discourse on Liquid Web and start building your online community.

How to enable and configure single sign-on (SSO) for Discourse on Liquid Web?

To enable and configure Single Sign-On (SSO) for Discourse on Liquid Web, you can follow these steps:

  1. Log in to your Discourse dashboard using your admin account.
  2. Navigate to the "Settings" section, then click on the "Login" tab.
  3. Scroll down to the "Enable SSO Provider" option and check the box to enable it.
  4. Open a new browser tab and log in to your Liquid Web account.
  5. In the Liquid Web Cloud Control Panel, go to "Manage" and select your site.
  6. Under the "Applications & Services" section, click on "Single Sign-On."
  7. Click on the "Get Started" button to configure SSO settings.
  8. In the "Identity Provider Issuer," enter the URL of your Discourse forum.
  9. Copy the "Certificate" from the Liquid Web SSO settings page and paste it into the "Identity Provider Certificate" field in your Discourse settings.
  10. In the "SLO Logout URL" field, enter the URL of your Discourse forum followed by "/session/slo" (e.g., https://forum.example.com/session/slo).
  11. Click on the "Save Changes" button to apply the settings.


After completing these steps, your Discourse forum should be configured to use Single Sign-On with Liquid Web as the identity provider. When users attempt to log in to the Discourse forum, they will be redirected to Liquid Web for authentication.


Note: Make sure to test the SSO integration thoroughly before deploying it to ensure it functions as expected.


How to enable and configure CDN (Content Delivery Network) for Discourse on Liquid Web?

To enable and configure a CDN for Discourse on Liquid Web, follow these steps:

  1. Sign up for a CDN service: There are several popular CDN providers available, such as Cloudflare, KeyCDN, and MaxCDN. Sign up for an account with one of these providers.
  2. Configure your CDN: After signing up, you will receive a CDN URL that you need to configure for your Discourse forum. Each CDN provider has different configuration procedures, so follow the instructions provided by your CDN provider to configure your CDN.
  3. Access your Discourse Admin Dashboard: Login to your Discourse Admin Dashboard by visiting https://your-domain.com/admin.
  4. Go to Settings: In the left-hand menu, click on "Settings".
  5. Enable CDN: Scroll down to the "asset_host" field and enter your CDN URL. For example, if your CDN URL is https://cdn.example.com, enter //cdn.example.com in the "asset_host" field. Make sure to prefix your CDN URL with // to ensure it works with both HTTP and HTTPS.
  6. Save Changes: Scroll down and click on the "Save Changes" button to apply the CDN configuration.
  7. Test your CDN: After enabling the CDN, you need to test if it is working correctly. Clear your browser cache and visit your Discourse forum. Inspect the page source code (Ctrl+U or right-click and select "View Page Source") and search for the URLs of static assets like CSS and JavaScript files. If the URLs start with your CDN URL, it means your CDN is working correctly.


Note: Some CDNs require additional configuration or integration steps, such as setting up DNS records or installing plugins. Refer to the documentation provided by your CDN provider for specific instructions.


Remember to monitor your Discourse forum after enabling the CDN to ensure there are no unexpected issues or conflicts with your website's functionality.


What is the process for customizing the Discourse email templates on Liquid Web?

To customize the Discourse email templates on Liquid Web, you can follow these steps:

  1. Log in to your Liquid Web account and access your server.
  2. Navigate to the Discourse installation directory. Depending on your setup, it may be located in a directory like /var/discourse.
  3. Once in the Discourse directory, look for the containers folder and navigate to app.yml.
  4. Open the app.yml file using a text editor.
  5. Search for the env: section in the app.yml file. Within this section, locate the DISCOURSE_CDN_URL line.
  6. Uncomment the DISCOURSE_CDN_URL line if it is commented out, and set it to your desired CDN URL. This will allow you to host custom email templates and assets on a CDN rather than on your server. If you do not want to use a CDN, you can skip this step.
  7. Save the app.yml file and close it.
  8. SSH into your server using a terminal or SSH client.
  9. Run the command cd /var/discourse (replace /var/discourse with the actual path to your Discourse installation if different).
  10. Run the command ./launcher enter app to enter the Discourse Docker container.
  11. Navigate to the Discourse configuration folder by running the command cd /var/www/discourse/config.
  12. Use a text editor to open the discourse_defaults.conf file.
  13. Locate the section that starts with # Customizing the email templates. You will find individual blocks that represent different email templates.
  14. Modify the content within these blocks to customize the email templates as per your requirements. You can use Liquid syntax within the templates for more advanced customization.
  15. Save the discourse_defaults.conf file and exit the editor.
  16. Exit the Docker container by running the exit command.
  17. Rebuild the Discourse app with the updated configurations by running the command ./launcher rebuild app. This may take a few minutes to complete.


After rebuilding, your customized email templates will be active. Make sure to test the email functionality to ensure the changes are applied correctly.


What is the process for disabling or removing a Discourse instance from Liquid Web?

To disable or remove a Discourse instance from Liquid Web, you can follow these general steps:

  1. Access your Liquid Web account: Log in to your Liquid Web Manage portal using your credentials.
  2. Navigate to the Discourse server: Locate and select the Discourse instance you want to disable or remove from your list of servers.
  3. Stop the Discourse instance: Click on the "Stop" or "Shutdown" button to gracefully stop the Discourse instance. This will ensure all processes are terminated correctly and data is saved.
  4. Backup your data (optional): If you want to retain your Discourse instance's data, it is recommended to take a backup. This can be done either through the Liquid Web backup system or through Discourse's built-in backup functionality.
  5. Delete the Discourse instance: Once you have stopped the instance and taken the necessary backups (if applicable), select the Discourse instance again and choose the "Delete" or "Terminate" option. This will permanently remove the instance from your Liquid Web account.


It is important to note that the exact steps may vary slightly depending on the specific Liquid Web portal and dashboard you are using. It is recommended to consult Liquid Web's documentation or contact their customer support for specific instructions tailored to your account.
