What is Discourse?
Discourse is modern forum software that can be easily installed on your Ubuntu-based Liquid Web VPS or Dedicated server to create a vibrant community-driven discussion board. Some of the more popular companies using Discourse to power their communities are New Relic, Cloudflare, and Docker.
Current requirements for Discourse include:
- Ruby 2.5+
- PostgreSQL 10+
- Redis 2.6+
- An outgoing MTA (Discourse does not provide email itself)

Step 1. Before you install Discourse, you will need to identify a subdomain that you will install the software on. An example subdomain would be “forum.example.com.”
Step 2. Next, we need to ensure that the DNS is set up correctly for that subdomain so your users can access the forum. It should be noted that you can use Cloudflare for your DNS, and it will work fine with your installation.
Step 3. Next, you should be logged in as the root user using the SSH credentials for your VPS server.
Step 4. (Optional) Discourse also suggests that you sign up for a transactional email provider like Mailgun, SendGrid, Mailjet, or Elastic Email before installation as the docker image does not provide that service. Before you begin the setup, you will need to have your SMTP information handy. During the initial setup, Discourse will need the SMTP server name, SMTP user, and SMTP password.
After you have logged in as the root user, we can begin the docker install by entering the following commands. You should use the root user throughout the rest of the setup and bootstrapping process.
root@host [~]# sudo -s root@host [~]# git clone https://github.com/discourse/discourse_docker.git /var/discourse
Now, cd into the Discourse folder.
root@host [~]# cd /var/discourse
Next, we’ll run the Discourse setup command.
root@host [~/var/discourse]# ./discourse-setup
Next, we will be asked a series of questions that are required to move forward with the installation.
Hostname for your Discourse? [forum.example.com]: Email address for admin account(s)? [email@example.com,firstname.lastname@example.org]: SMTP server address? [smtp.example.com]: SMTP port? : SMTP user name? [email@example.com]: SMTP password? [pa$$word]: Let's Encrypt account email? (ENTER to skip) [firstname.lastname@example.org]:
The Discourse setup will create an app.yml file and kick off the bootstrapping process, which can take anywhere from two to eight minutes. Once this portion completes, we will move on to the browser-based setup.
Verify Install and Continue Browser-Based Setup
Once the bootstrapping process is complete, you will be able to continue your Discourse forum setup via a web browser on the domain or subdomain.
The first time you access Discourse, you will need to set up an admin user. Add your email, username, and password as requested and click on the Register button.
Next, you will need to confirm your email address by clicking on the link provided within the activation email that was sent to the address that was provided on the last screen.
Once the admin’s email verification has been completed, you will be taken to the welcome screen where you are asked to complete thirteen additional questions to finish the setup.
After completing the setup wizard, you will see Staff topics and the READ ME FIRST: Admin Quick Start Guide info. This guide contains advice to further configure and customize your Discourse software.
When deploying Discourse to an Ubuntu server, we will use a sudo user instead of the root user since the root installation is discouraged in this type of setup.
Add sudo User
To add a sudo user, run the following command.
root@host [~]# adduser username
Then, we need to switch over to that new user.
root@host [~]# su - username
Install Discourse Dependencies
As a regular user, run this script in your terminal to set up the Rails development environment.
email@example.com [~]# bash <(wget -qO- https://raw.githubusercontent.com/techAPJ/install-rails/master/linux)
This script will install the following packages onto your system in preparation for Discourse.
- Ruby (stable)
Once we have run the script and installed the dependencies, let’s move forward and install Discourse itself.
Clone the Discourse repository into a ~/discourse folder of your choosing.
firstname.lastname@example.org [~]# git clone https://github.com/discourse/discourse.git ~/discourse
Set up the Database
Next, we need to create a role using the same name as your Ubuntu system username.
email@example.com [~]# sudo -u postgres createuser -s "$USER"
Now, cd into the folder where Discourse was cloned to.
Install Ruby Gems
Once in the discourse folder, we need to install our Ruby gems.
root@host [~/discourse]# source ~/.bashrc root@host [~/discourse]# bundle install
Next, we will set up our database configurations. Let’s set up our database using the following commands.
bundle exec rake db:create bundle exec rake db:migrate
Now, run this command to set up our specs.
bundle exec rake autospec
After that, we can start the rails server (it will only be available on localhost).
bundle exec rails server
We can then execute this command to have Rails listening on all interfaces, as well as being available remotely.
bundle exec rails server --binding=0.0.0.0
Verify Install and Continue Browser-Based Setup
Now, we should be able to connect to the Discourse app on http://localhost:3000 and complete the browser-based setup portion. (see above web browser setup pics)
Lastly, we can set up our categories and install any needed plugins to extend functionality in Discourse.
And that’s it! You now have a fully functional, innovative modern forum to start building your community.
