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.
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.
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
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.
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.
To activate the virtual environment, run the following command:
source env/bin/activate
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.
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.
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.
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
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.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
