PythonScrapyBasicSetup

Basic setup with random user agents and proxy addresses for Python Scrapy Framework.

Setup

1. Install Scrapy Framework

pip install Scrapy

Detailed installation guide

2. Install Beautiful Soup 4 for proxy middleware based on proxydocker lists

pip install beautifulsoup4

Detailed installation guide

3. Install Tor, Stem (controller library for Tor), and Privoxy (HTTP proxy server).

apt-get install tor python-stem privoxy

Hash a password with Tor:

tor --hash-password secretPassword

Then copy a hashed password and paste it with control port to /etc/tor/torrc:

ControlPort 9051
HashedControlPassword 16:72C8ADB0E34F8DA1606BB154886604F708236C0D0A54557A07B00CAB73

Restart Tor:

sudo /etc/init.d/tor restart

Enable Privoxy forwarding by adding next line to /etc/privoxy/config:

forward-socks5 / localhost:9050 .

Restart Privoxy:

sudo /etc/init.d/privoxy restart

Both Tor and Privoxy should be up & running (check netstat -l). If you used different password or control port, update settings.py.

If you get some errors regarding the pyOpenSSL (check this issue), try to downgrade the Twisted engine:

pip install Twisted==16.4.1

Usage

To see what it does just:

python run.py

Project contains three middleware classes in middlewares directory. ProxyMiddleware downloads IP proxy addresses and before every process request chooses one randomly. TorMiddleware has a similar purpose, but it relies on Tor network. RandomUserAgentMiddleware downloads user agent strings and saves them into 'USER_AGENT_LIST' settings list. It also selects one UA randomly before every process request. Middlewares are activated in settings.py file. This project also contains two spiders just for testing purposes, spiders/iptester.py and spiders/uatester.py. You can run them individually:

scrapy crawl UAtester
scrapy crawl IPtester

run.py file is a also good example how to include and run your spiders sequentially from one script.

If you have any questions or problems, feel free to create a new issue. Scrap responsibly!

Connection refused, setup in Docker

I setup an image on Ubuntu following the instruction. When I run scrapy it shows error.

Did I do anything wrong?
