To completely uninstall NGINX from your system, follow the appropriate instructions based on your operating system:

For Ubuntu/Debian-based systems:#

  1. Stop the NGINX service:

    sudo systemctl stop nginx

  2. Disable the NGINX service (so it doesn’t start on boot):

    sudo systemctl disable nginx

  3. Remove NGINX and its dependencies: Run the following command to remove the NGINX package:

    sudo apt-get purge nginx nginx-common nginx-full nginx-core

  4. Remove any unused dependencies: After removing NGINX, you can clean up any unused packages:

    sudo apt-get autoremove

  5. Delete configuration and log files (optional): If you want to remove all configuration and log files (warning: this deletes custom configurations), use:

    sudo rm -rf /etc/nginx /var/log/nginx /var/cache/nginx

  6. Check if NGINX is completely removed: You can check if NGINX is still installed by typing:

    which nginx

    If nothing is returned, NGINX is successfully uninstalled.

For CentOS/RHEL-based systems:#

  1. Stop the NGINX service:

    sudo systemctl stop nginx

  2. Disable NGINX from starting at boot:

    sudo systemctl disable nginx

  3. Remove the NGINX package: Run the following command to remove NGINX:

    sudo yum remove nginx

  4. Clean up unused dependencies: You can remove unused dependencies with:

    sudo yum autoremove

  5. Remove configuration and log files (optional): If you want to remove the configuration files and logs, use:

    sudo rm -rf /etc/nginx /var/log/nginx /var/cache/nginx

  6. Verify removal: To confirm NGINX is uninstalled, check:

    which nginx

    If nothing is returned, it means NGINX is successfully uninstalled.

For Arch Linux:#

  1. Stop the NGINX service:

    sudo systemctl stop nginx

  2. Disable the NGINX service:

    sudo systemctl disable nginx

  3. Uninstall NGINX:

    sudo pacman -Rns nginx

  4. Remove configuration and log files (optional):

    sudo rm -rf /etc/nginx /var/log/nginx /var/cache/nginx

  5. Verify the removal: Check that NGINX is removed by:

By following these steps, you will have completely uninstalled NGINX from your system.
