Prerequisites

Before you begin the installation process, ensure your system meets the following prerequisites. Meeting these requirements will help ensure a smooth and trouble-free installation of Askbot on Debian 12.

• A running Debian 12 server: You need a server with Debian 12 installed. This can be a physical server, a virtual machine, or a cloud instance.
• Root or sudo privileges: You’ll need root or sudo privileges to install software and configure the system.
• Basic Linux knowledge: Familiarity with Linux command-line operations is essential.
• A domain name (optional): If you plan to make your Askbot platform publicly accessible, you’ll need a domain name.

Step 1: System Preparation

First, update the package index and upgrade existing packages to their latest versions. This ensures that you have the most recent software and security updates. It’s very important to keep your system up to date.

sudo apt update && sudo apt upgrade -y

Next, install essential tools like curl, wget, and git, which are necessary for downloading and managing software packages. Build tools are also required for compiling some Python packages.

sudo apt install curl wget git build-essential -y

Now, create a dedicated user account for Askbot to enhance security. Avoid running Askbot under the root user. Replace askbot with your desired username.

sudo useradd -m -s /bin/bash askbot
sudo passwd askbot
sudo usermod -aG sudo askbot

• useradd -m -s /bin/bash askbot: Creates a new user named “askbot” with a home directory and sets the default shell to Bash.
• passwd askbot: Sets a password for the newly created user.
• usermod -aG sudo askbot: Adds the “askbot” user to the “sudo” group, granting it administrative privileges.

Step 2: Install Python and Create a Virtual Environment

Askbot is a Python-based application, so you’ll need to install Python and the venv module for creating virtual environments. Using a virtual environment isolates Askbot’s dependencies from other Python projects on your system, preventing conflicts.

sudo apt install python3 python3-pip python3-venv -y

Create a virtual environment for Askbot. Choose a suitable directory, such as /home/askbot/askbot_env, to house the virtual environment files.

python3 -m venv /home/askbot/askbot_env

Activate the virtual environment. Activating the virtual environment sets up your shell to use the virtual environment’s Python interpreter and package directories. Each time you want to work on the Askbot project, you’ll need to activate the virtual environment.

source /home/askbot/askbot_env/bin/activate

Verify that the virtual environment is active by checking the Python version. The output should indicate that you’re using the Python interpreter from within the virtual environment.

python3 --version

Step 3: Install PostgreSQL

Askbot supports PostgreSQL as its database backend. PostgreSQL is a powerful and reliable open-source relational database system that provides excellent performance and scalability. Install PostgreSQL, the libpq-dev package (required for Python’s PostgreSQL adapter), and the postgresql-contrib package (which provides additional utilities).

sudo apt install postgresql postgresql-contrib libpq-dev -y

Switch to the postgres user, which is the default administrative user for PostgreSQL.

sudo su - postgres

Access the PostgreSQL shell. This allows you to execute SQL commands to manage the database.

psql

Create a database for Askbot. Replace askbot with your desired database name.

CREATE DATABASE askbot;

Create a user for Askbot with a secure password. Replace askbot_user with your desired username and secure_password with a strong password.

CREATE USER askbot_user WITH PASSWORD 'secure_password';

Grant the Askbot user all privileges on the Askbot database.

GRANT ALL PRIVILEGES ON DATABASE askbot TO askbot_user;

Exit the PostgreSQL shell.

\q

Exit the postgres user account.

exit

Install the psycopg2-binary package, which is a PostgreSQL adapter for Python. This package allows Askbot to connect to the PostgreSQL database.

pip install psycopg2-binary

Step 4: Install Askbot

With the dependencies installed and the database configured, you can now install Askbot. It is recommended to install a specific version of Askbot to ensure compatibility.

pip install askbot==0.11.1

Create a directory for the Askbot project. This directory will contain the project’s settings, URLs, and other configuration files. Replace /home/askbot/askbot_project with your desired project directory.

mkdir /home/askbot/askbot_project && cd /home/askbot/askbot_project

Run the Askbot setup script to initialize the project. The setup script will prompt you for various configuration settings, such as the database credentials, admin email, and site details.

askbot-setup

During the setup process, you’ll be prompted to provide the following information:

• Directory Path: The location where Askbot will be deployed.
• Database Engine: Select PostgreSQL.
• Database Name: Enter the name of the database you created (e.g., askbot).
• Database User: Enter the username you created (e.g., askbot_user).
• Database Password: Enter the password you set for the user.
• Admin Email: Enter the email address for the site administrator.
• Site Details: Enter the name and other details for your Askbot site.

Collect static files. Static files are CSS, JavaScript, and image files that are served directly by the web server. This command collects all the static files from Askbot and its dependencies and places them in a single directory for easy serving.

python manage.py collectstatic

Migrate the database. This command creates the necessary database tables for Askbot to function correctly.

python manage.py migrate

Step 5: Configure uWSGI

uWSGI is a fast and efficient application server that is commonly used to serve Python web applications. You will need to install and configure uWSGI to serve Askbot.

pip install uwsgi

Create a uWSGI configuration file. This file tells uWSGI how to run the Askbot application. Create a file named askbot.ini in the /etc/uwsgi/sites directory.

sudo nano /etc/uwsgi/sites/askbot.ini

Add the following configuration to the askbot.ini file. Replace askbot with the appropriate user, askbot_project with your project name, and adjust the paths as necessary.

[uwsgi]
  project = askbot_project
  uid = askbot
  gid = www-data
  
  chdir = /home/askbot/%(project)
  home = /home/askbot/askbot_env
  
  module = %(project).wsgi:application
  
  master = true
  processes = 5
  
  socket = /run/uwsgi/%(project).sock
  chmod-socket = 660
  
  vacuum = true
  
  die-on-term = true

Explanation of the configuration options:

• project: The name of the Askbot project.
• uid: The user that uWSGI will run as.
• gid: The group that uWSGI will run as.
• chdir: The directory to change to before running the application.
• home: The virtual environment to use.
• module: The WSGI module to load.
• master: Enable the master process.
• processes: The number of worker processes to run.
• socket: The socket to listen on.
• chmod-socket: The permissions to set on the socket.
• vacuum: Clean up temporary files on exit.
• die-on-term: Die when receiving a termination signal.

Enable the uWSGI service. This creates a symbolic link from the /etc/uwsgi/sites directory to the /etc/systemd/system/multi-user.target.wants directory, which tells systemd to start the uWSGI service automatically at boot time.

sudo ln -s /etc/uwsgi/sites/askbot.ini /etc/systemd/system/multi-user.target.wants/askbot.service

Start the uWSGI service.

sudo systemctl start uwsgi

Step 6: Configure Nginx

Nginx will act as a reverse proxy, forwarding requests to uWSGI. Install Nginx.

sudo apt install nginx -y

Create an Nginx virtual host configuration file. This file tells Nginx how to handle requests for your Askbot site. Create a file named askbot in the /etc/nginx/sites-available directory.

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

Add the following configuration to the askbot file. Replace example.com with your domain name and adjust the paths as necessary.

server {
  listen 80;
  server_name example.com;
  
  location / {
  include uwsgi_params;
  uwsgi_pass unix:/run/uwsgi/askbot_project.sock;
  }
  
  location /static {
  alias /home/askbot/askbot_project/static;
  }
  
  location /media {
  alias /home/askbot/askbot_project/media;
  }
  }
  

Explanation of the configuration options:

• listen: The port to listen on.
• server_name: The domain name for your Askbot site.
• location /: Handles all requests to the root of the domain.
• include uwsgi_params: Includes the uWSGI parameters.
• uwsgi_pass: The uWSGI socket to pass requests to.
• location /static: Serves static files.
• alias: The directory where static files are located.
• location /media: Serves media files.

Create a symbolic link from the /etc/nginx/sites-available directory to the /etc/nginx/sites-enabled directory. This tells Nginx to enable the virtual host.

sudo ln -s /etc/nginx/sites-available/askbot /etc/nginx/sites-enabled/

Test the Nginx configuration for any syntax errors.

sudo nginx -t

If the configuration test is successful, restart Nginx to apply the changes.

sudo systemctl restart nginx

Step 7: Secure with SSL using Let’s Encrypt

To secure your Askbot installation, you can use Let’s Encrypt to obtain a free SSL certificate. This will encrypt the traffic between your users and the server, protecting sensitive data.

sudo apt install certbot python3-certbot-nginx -y

Obtain an SSL certificate for your domain. Replace example.com with your actual domain name and admin@example.com with your email address.

sudo certbot --nginx -d example.com --agree-tos --email admin@example.com --redirect

Certbot will automatically configure Nginx to use the SSL certificate and set up automatic renewal. Make sure the domain name is pointing to your server, or the process will fail. You will also need to accept the terms of service.

Step 8: Access Askbot

Once the installation and configuration are complete, you can access your Askbot platform by visiting your domain name in a web browser (e.g., http://example.com). The setup will redirect to https://example.com automatically. Ensure that your DNS records are correctly configured to point to your server’s IP address.

If you can’t access the site, check the following:

• Nginx and uWSGI are running
• Firewall rules allow traffic on ports 80 and 443
• DNS records are correctly configured

Troubleshooting Common Issues

Even with careful planning, issues can arise during the installation process. Here are some common problems and their solutions:

• Missing dependencies: If you encounter errors related to missing dependencies, double-check that you’ve installed all the required packages.
• Database connection issues: Verify that the PostgreSQL server is running and that the database credentials in Askbot’s settings are correct.
• Nginx/uWSGI errors: Check the Nginx error logs (/var/log/nginx/error.log) and the system logs (/var/log/syslog) for any error messages.
• Static files not loading: Ensure that you’ve run the python manage.py collectstatic command and that the Nginx configuration is correctly serving static files.
• Incorrect file permissions: Ensure that the Askbot user has the necessary permissions to access the project directory and its files.
