In this video i'll show you one way of running your web scrapers automatically in the cloud, using cronjobs. we utilise a linux vm from Digital Ocean and download and run our code at a set interval. I cover creating a droplet, downloading code from git and isntalling requirements.

Oh man, this was a life saver. I really enjoy your series, everytime I need to scrape something I know you must have done something similar!

John you’re great, been watching your content for the past few days, you explain everything so well and show all different scenarios for beginners or more advanced, ive a few years of experience with python and scraping but still learning a lot from you 🙏🏾

@itsaj007 Год назад

quick question, i have a web scraper script that works on local computer but not on a rdp/vps, tried different ip etc. but no luck

@JohnWatsonRooney Год назад

hard to say without knowing what the error is, when you say different IPs did you mean VPS IPs or proxies? If its not that its usually an environment issue, like different python versions, or env variables

my scraper is done with nodejs so not the same process but still very helpful. thanks!

@ed-salinas-97 3 года назад

I'm a little bit new to Linux commands, but I wasn't getting the cron.log file to show up in my Home directory. I ended up having to change the permissions of my Home directory, and then it worked. I was using an Ubuntu VM instance on GCP, though. Not sure if that makes a difference from Digital Ocean.

Hi sir. I have an app scraper. My app scrapes news site and extract urls, writes to .txt file. I deployed my app to Heroku. But Heroku doesn't have file system and doesn't update .txt file. Can you show methods connect databases and Heroku? For exmple external clouds or Postgres.

Bro is it possible to use this method in windows?

@JohnWatsonRooney 3 года назад

Yes, it’s called scheduled tasks in windows - but I’ve never used it so I’m afraid I don’t know how it compares or how to use it

@Cephasprincely 3 года назад

@gotenksjd 2 года назад

John hi! One question... when I run the script manually it runs ok, but when it is schedulled to run in the crontab it is not running. The paths are complete. What could I be missing?

@gotenksjd 2 года назад

The path for the creds file inside must also have the path of the linux server too. Solved it!😊

@alexmulo 3 года назад

Hi John, why do you prefer the cloud over a local solution using a raspberry pi for example? Thanks

@JohnWatsonRooney 3 года назад

Generally yes, as I don’t have to worry about it as it’s all managed. I do have a Pi video coming though!

@emadkamel1961 2 года назад

This is great and valuable lesson. However, what if I would like to run my scraper code without turning on my machine / laptop Is it possible to integrate my code some how into my Wordpress site for example? Or get it to run in the cloud? If yes, can you kindly elaborate and or share the link of your relevant tutorial. Looking forward to hearing back from you.

@JohnWatsonRooney 2 года назад

Hey, yes you can absolutely run in the cloud. I use digital ocean to run a Linux machine in the cloud that I run scripts on a cron job

Have you tried opening with selenium then saving the html by page_source? This will give you the html which would be easier to get the data from with bs4 - I did a video on it not long ago. Thanks!

For some reason I can't get my cronjobs to work or test correctly on my AWS EC2 instance. I have this setup and the test file isn't updating. From the top directory on EC2, I have to navigate to a home folder, then an ubuntu folder, then in ubuntu folder is my working directory where I have a test.py script and a test cronlog file. I also have a main folder for the actual project I have trying to schedu.e Any tips? Below is my test setup * * * * * usr/bin/python3 /home/ubuntu/test.py >> /home/ubuntu/testcron123.log

@JohnWatsonRooney Год назад

Not sure specifically but I would check user permissions on the folder and check which users crontab you are using, I know users and permissions tripped me up before
