Web scraping | Scrapy Cron Virtual Environment
How to run a Scrapy web scraping project in a virtual environment every day and scrape results to a database. (I use postgres, but same concept applies whichever database you use).
⦾ Create a bash script to activate virtual environment and run spider via CRON.

--
#!/usr/bin/env bash
source /home/pi/Documents/Scrape/bin/activate
cd /home/pi/Documents/Scrape/Scrapy19/jobz/spiders
scrapy crawl jobzspider
--
⦾ Schedule in CRON
For example, you can run a backup of all your user accounts
at 5 a.m every week with:
0 15 * * * ~/Documents/Scrape/Scrapy19/jobz/spiders/cj.sh

For more information see the manual pages of crontab(5) and cron(8)

Proxies
=================================================
If you need a good, easy to use proxy, I was recommended this one, and having used ScraperAPI for a while I can vouch for them. If you were going to sign up anyway, then maybe you would be kind enough to use the link and the coupon code below?
You can also do a full working trial first as well, (unlike some other companies). The trial doesn't ask for any payment details either so all good! 👍
