To install Discourse on DigitalOcean, you can follow this tutorial:
- Create a DigitalOcean account: First, sign up for an account on DigitalOcean if you do not already have one. This will allow you to create a virtual server where you can install Discourse.
- Create a Droplet: After logging in, click on the "Create" button and select "Droplets" from the drop-down menu. Choose a plan that suits your needs and select your desired region. You can also choose to use IPv6 if needed. Then, select the "Discourse" application under the "One-click apps" tab.
- Customize your Droplet: Give your Droplet a name and select additional options if required, such as block storage, backups, or monitoring. You can also add your SSH keys for secure access to the Droplet.
- Choose the number of Droplets: Decide the number of Droplets you want to create. It is recommended to start with one in most cases.
- Choose a size: Select the size for your Droplet based on your requirements. Consider the number of users and expected activity on your Discourse instance.
- Select additional settings: Further customize your Droplet if desired, such as enabling private networking or enabling backups.
- Create your Droplet: Click on the "Create Droplet" button to create your virtual server.
- Access your Droplet via SSH: Once the Droplet is created, you can access it via Secure Shell (SSH) to continue the installation process. You can use tools like PuTTY or the built-in Terminal on macOS/Linux.
- Install Discourse: Follow the installation instructions provided by Discourse for Ubuntu-based servers. These will include cloning the Discourse repository, creating a Discourse user and database, configuring your Discourse instance, and launching it.
- Configure DNS: In order to access your Discourse instance through a domain name, you need to set up proper DNS records. You can either use DigitalOcean's DNS management or another DNS provider of your choice.
- Complete setup: Once the installation is complete, you can access your Discourse forum by visiting your Droplet's IP address or the domain name you have associated with it.
Remember to reference the full tutorial for detailed instructions and specific commands to execute during the installation process.

What is a Discourse container?
A Discourse container refers to a virtualized environment where the Discourse application, an open-source discussion platform, can be deployed and run. It allows for easy installation, configuration, and management of Discourse by bundling all the necessary dependencies and components in a single package.
Discourse containers are typically based on Docker technology, which provides lightweight, isolated, and scalable environments. They contain the necessary software components, including the operating system, database, web server, and all the dependencies required for Discourse to function properly.
Using a Discourse container simplifies the deployment process as it abstracts away the complexities of setting up the various components individually. It enables easy cloning, backing up, and migrating of Discourse instances, making it convenient for both developers and administrators to deploy and manage the platform.
How to configure Nginx as a reverse proxy for Discourse?
To configure Nginx as a reverse proxy for Discourse, follow these steps:
- Install Nginx: If you haven't already, install Nginx on your server. You can do this by running the following command: sudo apt-get update sudo apt-get install nginx
- Configure Nginx to act as a reverse proxy: Remove the default Nginx configuration file: sudo rm /etc/nginx/sites-available/default Create a new Nginx configuration file for Discourse: sudo nano /etc/nginx/sites-available/discourse Add the following configuration to the file: server { listen 80; server_name your_discourse_domain.com; location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://127.0.0.1:3000; } } Save and close the file.
- Enable the Nginx configuration: sudo ln -s /etc/nginx/sites-available/discourse /etc/nginx/sites-enabled/discourse
- Restart Nginx to apply the changes: sudo service nginx restart
- Start Discourse: If you haven't already, start Discourse by running the following command inside the Discourse directory: ./launcher start app
- Test the setup: Open your web browser and navigate to your Discourse domain. You should see your Discourse instance loaded through the Nginx reverse proxy.
Note: Make sure to replace your_discourse_domain.com with your actual domain name or IP address. Also, adjust the Nginx configuration as necessary if you're using SSL or have specific requirements.
How to start and manage the Discourse container on DigitalOcean?
To start and manage the Discourse container on DigitalOcean, follow these steps:
- Create a Droplet: Log in to your DigitalOcean account and create a new Droplet. Choose the size and region according to your requirements.
- Set up a domain name: Set up a domain name for your Discourse installation. You can either use an existing domain or register a new one.
- Configure DNS settings: Configure the DNS settings of your domain to point to your Droplet's IP address. Go to your domain registrar's website and add an "A record" with the Droplet's IP address.
- Access your Droplet: Once the Droplet is created, you can access it via SSH. Use an SSH client like PuTTY (for Windows) or the built-in Terminal (for Linux and macOS). Connect to your Droplet using the IP address and the root credentials provided by DigitalOcean.
- Set up Discourse: On your Droplet, clone the Discourse repository using the following command: git clone https://github.com/discourse/discourse.git /var/discourse
- Configure Discourse: Navigate to the /var/discourse directory and copy the samples/standalone.yml file to containers/app.yml. Edit app.yml to configure your Discourse installation. You'll need to set the DISCOURSE_HOSTNAME with your domain name, and provide other details like email configuration and SMTP settings if desired.
- Install Discourse: Run the following command to install Discourse: cd /var/discourse ./launcher bootstrap app This command will download the necessary Docker images and install all dependencies.
- Rebuild Discourse: After the installation completes, run the following command to rebuild Discourse with the updated configuration: ./launcher rebuild app This command will start the Docker container and configure Discourse using the provided settings.
- Finish the setup: Once the rebuild completes, your Discourse instance should be running. Access it by visiting your domain name in a web browser. Follow the prompts to complete the initial setup, including creating an admin account.
- Manage Discourse: To manage your Discourse installation, you can SSH into your Droplet and perform operations using the ./launcher command. For example, you can start/stop the container, update Discourse, or view logs.
That's it! You have now successfully started and managed the Discourse container on DigitalOcean.
What is a reverse proxy?
A reverse proxy is a server or software component that sits between client devices and web servers. It receives requests from clients and forwards them to the appropriate server on behalf of the clients. The server's responses to those requests are then returned by the reverse proxy to the clients.
The main purpose of a reverse proxy is to enhance security, performance, and scalability. It acts as an intermediary, hiding the identity and characteristics of the backend servers from the clients, thus adding an extra layer of protection. It can also distribute incoming requests across multiple servers based on various algorithms, enabling load balancing and reducing the burden on individual servers.
Additionally, a reverse proxy can cache frequently accessed content, serving it directly to clients without forwarding the request to the server. This not only improves speed and reduces bandwidth usage but also helps to cope with high traffic volumes.
Overall, a reverse proxy acts as a gateway between clients and servers, improving security, performance, and reliability of web applications.
