How To Install Discourse on Ubuntu 22.04 LTS Jammy Linux

Learn the commands to install and set up the Discourse forum on Ubuntu 22.04 Server Jamy JellyFish using the terminal to establish your own community. 

Discourse is open-source forum software that can also be used as a comment system for a website. The creators want to create the basis for modern Internet forums.

Discourse relies on Ruby on Rails, Postgres, and Redis. On the client side, the makers rely on the JavaScript framework Ember.js. The software is licensed under the GPL 2.0 license and the source code can be found on GitHub. It was launched in 2014, hence has been around for 7 years now. In addition, the creators – including Stack Overflow co-founder Jeff Atwood – integrated various newer elements that we know from social networks or comment systems such as Disqus.

In addition to the traditional login via email, Discourse users should also be able to log in with their existing accounts on Twitter, Facebook, Google, Yahoo, or GitHub.

Steps to install Discourse forum on Ubuntu 22.04 LTS Server

The steps given are common for other Ubuntu or Debian-based Linux systems including Linux Mint, MX Linux, POP OS, and more…

Requirements:

• Ubuntu 22.04 Server
• Docker
• A non-root sudo user
• Internet connection
• at least 2GB of RAM

1. Update Ubuntu 22.04 Server

To add a repository over HTTPS we need to install ca-certificates, along with some other tools we required further in the tutorial. First, run the system update command and then install the required packages:

sudo apt update -y

sudo apt-get install apt-transport-https ca-certificates git curl gnupg -y

2. Add Docker GPG key and Repository

Discourse on Ubuntu 22.04 needs Docker to get installed properly, hence, to make sure we have the latest version of it; let’s add Docker repository and GPG Key using the given commands:

Add Key:

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Add Repo:

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update

3. Install Docker for Discourse

Now, run the given command to install the docker platform and other tools of it on your Debian 11 Linux.

sudo apt-get install docker-ce docker-ce-cli containerd.io -y

4. Downloading Discourse on Ubuntu 22.04

Once the Docker is on our system, let’s create a dedicated directory for Discourse and then clone its git repository for further installation.

sudo mkdir /var/discourse

Now clone the git repo 

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

5. Install and configure Discourse for Ubuntu 22.04

First switch to the directory we have created and clone the directory.

cd /var/discourse

Start Script

Now, start the script:

sudo ./discourse-setup

The setup will ask you to add the domain address which you want to use with Discourse:

For example: forum.example.com

After that to send the mail, the user has to set the SMTP server address of the mail server you want to use. It will ask for the following items:

SMTP server address -
SMTP user name -
SMTP port -
SMTP password -

You can check out the official Discourse page for solving problems related to email. Hence, make sure SMPT details are right otherwise you won’t be able to use Discourse later.

6. Access web interface

Now, open your browser that can access the domain name you have registered for Discourse. After that in the URL, point the browser to your Discourse’s Domain.

For example: Here we are using- forum.how2shout.com

https://forum.how2shout.com

7. Register Admin Account

Click on the Register Button to create an account to start using Discourse

8. Keep Upgrade Discourse

In the future, if you want to upgrade your installation then follow the given commands:

cd /var/discourse

sudo git pull

sudo ./launcher rebuild app
