How to Install Isso on Ubuntu Server Latest

Introduction

Isso is a Flask-based commenting server, it has low memory usage and supports caching engines like memcached and Redis. This tutorial explains the installation and configuration of Isso on Ubuntu Server.

Prerequisites

  • A server running Ubuntu 20.04 or later.
  • Non-root user with sudo privileges.

Step 1: Update the System

The first step is to update your system packages to their latest versions.

sudo apt update && sudo apt upgrade -y

Step 2: Install Required Packages

Install the packages required to build and run Isso.

sudo apt install python3-pip python3-dev python3-venv

Step 3: Create a Python Virtual Environment

A virtual environment is an isolated environment that keeps the project dependencies separate from system dependencies. Create a directory for the virtual environment and create a new virtual environment with Python.

mkdir ~/isso
cd ~/isso
python3 -m venv venv
source venv/bin/activate

Step 4: Install Isso

Now, install Isso within the virtual environment.

pip install isso

Step 5: Create a Configuration File

Create a configuration file for Isso using the example configuration from the Isso repository.

mkdir ~/isso/config
cd ~/isso/config
wget https://raw.githubusercontent.com/posativ/isso/master/isso.cfg.example -O isso.cfg

Edit the configuration file according to your needs. You can open the file in a text editor.

nano ~/isso/config/isso.cfg

Step 6: Configure Isso as Systemd Service

Create a systemd service file for Isso that will allow us to run Isso as a service and restart it on system boot.

sudo nano /etc/systemd/system/isso.service

Add the following lines to it:

[Unit]
Description=Isso Comment Server
After=network.target

[Service]
PIDFile=/run/isso/isso.pid
User=www-data
Group=www-data
WorkingDirectory=/opt/isso
ExecStart=/opt/isso/bin/python /opt/isso/bin/isso run
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
Restart=always

[Install]
WantedBy=multi-user.target

Note that the user and group need to be updated for your system.

Save and close the file.

Ctrl + X and then Y and then Enter.

Start the Isso service using the following command:

sudo systemctl start isso

Verify the service is running:

systemctl status isso

Enable the service to start automatically on boot:

sudo systemctl enable isso

Step 7: Configure Firewall (Optional)

If you have a firewall enabled, you will need to open access to the port that Isso is running on. By default, Isso runs on port 8080.

sudo ufw allow 8080/tcp

Conclusion

You have successfully installed Isso on Ubuntu Server Latest. Isso can be used with a variety of platforms like Hugo, Jekyll, Medium and many more.
