Change owner and group to www-data/www-data.

$ sudo chown -R www-data:www-data /srv/archivebox

Ensure that application can store data in output directory.

$ sudo chmod 770 /srv/archivebox/output

Web-server configuration

Install nginx web-server.

$ sudo apt install nginx

Disable default configuration.

$ sudo unlink  /etc/nginx/sites-enabled/default

Create /etc/nginx/sites-available/archivebox configuration file.

server {
  listen 80;
  server_name _;
  root /srv/archivebox/output/;
  index index.html;
  location / {
    try_files $uri $uri/ =404;
  }
  location /archive/ {
    autoindex on;
  }
}

Enable this specific configuration.

$ sudo ln -s /etc/nginx/sites-available/archivebox /etc/nginx/sites-enabled/

Reload nginx service.

$ sudo systemctl reload nginx

Archive URL

Finally, use the following code snippet to archive specific URL.

$ URL="http://lwn.net"; sudo -u www-data bash -c "cd /srv/archivebox/; set -a; source etc/ArchiveBox.conf; echo $URL | /srv/archivebox/archive"

This can be more or less complicated, you will see next week why I am using this particular way to perform archiving process.
