How to Install Coral on Elementary OS Latest

In this tutorial, we will go through the steps on how to install Coral on Elementary OS Latest. Coral is a free and open-source project developed by Mozilla and The New York Times to help create better communities online.

Follow the steps below to install Coral on Elementary OS Latest.

Step 1: Update Your System

Before installing Coral, it is important to ensure that your system is up-to-date. Open a terminal and run the following command:

sudo apt update && sudo apt upgrade

This command will update your system and install any available updates.

Step 2: Install Required Dependencies

To install Coral, you need to install some dependencies first. Open a terminal and run the following command:

sudo apt-get install build-essential git python3-venv python3-dev libpq-dev postgresql postgresql-contrib redis-server nginx curl

Step 3: Clone the Coral Repository

Once the dependencies are installed, you need to clone the Coral repository. Open a terminal and run the following command:

git clone https://github.com/coralproject/talk.git

This command will clone the Coral git repository to your current directory.

Step 4: Create a Virtual Environment

To avoid conflicts with other Python packages on your system, it is recommended to create a virtual environment for Coral.

Open a terminal and navigate to the cloned Coral directory. Once you are inside the directory, run the following command to create a virtual environment:

python3 -m venv env

This command will create a virtual environment named env inside the Coral directory.

Step 5: Activate the Virtual Environment

To activate the virtual environment, run the following command:

source env/bin/activate

Step 6: Install Coral

Once the virtual environment is activated, run the following command to install the Coral dependencies:

pip3 install -r requirements.txt

This command will install all the dependencies required by Coral.

Step 7: Configure PostgreSQL

Coral requires a PostgreSQL database to store its data. Run the following commands to configure PostgreSQL:

sudo su postgres
createuser talk
createdb talk
psql
GRANT ALL PRIVILEGES ON DATABASE talk to talk;
ALTER USER talk PASSWORD 'password';
\q
exit

These commands will create a PostgreSQL user and database for Coral and set the user's password.

Step 8: Configure Coral

Coral uses environment variables to configure its settings. Open a terminal and navigate to the Coral directory. Once you are inside the directory, run the following command to create a .env file:

cp .env.sample .env

This command will create a copy of the .env.sample file named .env.

Open the .env file using a text editor and modify the following lines:

TALK_MONGO_URL=postgresql://talk:password@localhost:5432/talk
TALK_REDIS_URL=redis://localhost:6379/0

Replace the password with the password you set for the talk user in Step 7.

Step 9: Set Up NGINX

Coral uses NGINX to serve its web interface. Run the following command to create a new NGINX configuration file:

sudo nano /etc/nginx/sites-available/talk

Copy and paste the following NGINX configuration into the file:

upstream talk {
    server 127.0.0.1:3000;
}

server {
    listen 80;
    server_name your-domain.com;

    root /var/www/html;

    location / {
        proxy_pass http://talk;
        proxy_redirect http://talk/ /;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Replace your-domain.com with your own domain name. Save and exit the file.

Run the following commands to enable the NGINX site and restart NGINX:

sudo ln -s /etc/nginx/sites-available/talk /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

Step 10: Start Coral

Once everything is configured, run the following command to start Coral:

python3 bin/run.py

This command will start Coral and it will be available at http://your-domain.com (replace your-domain.com with your own domain name).

Congratulations! You have successfully installed Coral on Elementary OS Latest.
