Cron job

Add this to your crontab to run the job daily at 9 AM:

crontab -e

00 09 * * * cd PATH_TO_PROJECT/packtpub-crawler && /usr/bin/python script/spider.py --config config/prod.cfg >> /tmp/packtpub.log 2>&1

Systemd service

Create two files in /etc/systemd/system:

1. packtpub-crawler.service

[Unit]
Description=run packtpub-crawler

[Service]
User=USER_THAT_SHOULD_RUN_THE_SCRIPT
ExecStart=/usr/bin/python2.7 PATH_TO_PROJECT/packtpub-crawler/script/spider.py -c config/prod.cfg

[Install]
WantedBy=multi-user.target

2. packtpub-crawler.timer

[Unit]
Description=Runs packtpub-crawler every day at 7

[Timer]
OnBootSec=10min
OnActiveSec=1s
OnCalendar=*-*-* 07:00:00
Unit=packtpub_crawler.service
Persistent=true

[Install]
WantedBy=multi-user.target

Enable the script with sudo systemctl enable packtpub_crawler.timer. You can test the service with sudo systemctl start packtpub_crawler.timer and see the output with sudo journalctl -u packtpub_crawler.service -f.

Newsletter

The script downloads also the free ebooks from the weekly packtpub newsletter. The URL is generated by a Google Apps Script which parses all the mails. You can get the code here, if you want to see the actual script, please clone the spreadsheet and go to Tools > Script editor....

To use your own source, modify in the config

url.bookFromNewsletter=https://goo.gl/kUciut

The URL should point to a file containing only the URL (no semicolons, HTML, JSON, etc).

You can also clone the spreadsheet to use your own Gmail account. Subscribe to the newsletter (on the bottom of the page) and create a filter to tag your mails accordingly.

Troubleshooting

• ImportError: No module named paramiko

Install paramiko with sudo -H pip install paramiko --ignore-installed

• Failed building wheel for cryptography

Install missing dependencies as described here

virtualenv

# install pip + setuptools
curl https://bootstrap.pypa.io/get-pip.py | python -

# upgrade pip
pip install -U pip

# install virtualenv globally 
sudo pip install virtualenv

# create virtualenv
virtualenv env

# activate virtualenv
source env/bin/activate

# verify virtualenv
which python
python --version

# deactivate virtualenv
deactivate

Development (only for spidering)

Run a simple static server with

node dev/server.js

and test the crawler with

python script/spider.py --dev --config config/dev.cfg --all
