2018 Scrapy Environment Enhance(3)Docker ENV

Set Up Scrapy Ubuntu DEV
>sudo apt-get install -qy python python-dev python-distribute python-pip ipython
>sudo apt-get install -qy firefox xvfb
>sudo apt-get install -qy libffi-dev libxml2-dev libxslt-dev lib32z1-dev libssl-dev
> sudo apt-get install python3-venv
> sudo apt-get install python3-dev
> sudo apt install unzip
> sudo apt-get install libxi6 libgconf-2-4
> sudo apt-get install libnss3 libgconf-2-4
> sudo apt-get install chromium-browser

If need, make it to remember the git username and password
> git config credential.helper 'cache --timeout=300000'

Create the virtual ENV and activate that
> python3 -m venv ./env
> source ./env/bin/activate

> pip install --upgrade pip
> pip install selenium pyvirtualdisplay
> pip install boto3
> pip install beautifulsoup4 requests

Install Twisted
> wget http://twistedmatrix.com/Releases/Twisted/17.9/Twisted-17.9.0.tar.bz2
> tar xjf Twisted-17.9.0.tar.bz2
> python setup.py install

> pip install lxml scrapy scrapyjs

Install Browser and Driver
> wget https://chromedriver.storage.googleapis.com/2.37/chromedriver_linux64.zip
> unzip chromedriver_linux64.zip
> chmod a+x chromedriver
> sudo mv chromedriver /usr/local/bin/

> chromedriver --version
ChromeDriver 2.37.544315 (730aa6a5fdba159ac9f4c1e8cbc59bf1b5ce12b7)

> chromium-browser -version
Chromium 65.0.3325.181 Built on Ubuntu , running on Ubuntu 16.04

Setup Tor Network Proxy
> sudo apt-get install tor
> sudo apt-get install netcat
> sudo apt-get install curl
> sudo apt-get install privoxy

Check my Local IP
> curl http://icanhazip.com/
52.14.197.xxx

Set Up Tor
> tor --hash-password prxxxxxxxx
16:01D5D02xxxxxxxxxxxxxxxxxxxxxxxxxxx

> cat /etc/tor/torrc
ControlPort 9051

> cat /etc/tor/torrcpassword
HashedControlPassword 16:01D5D02EFA3D6A5xxxxxxxxxxxxxxxxxxx

Start Tor
> sudo service tor start

Verify it change my IP
> torify curl http://icanhazip.com/
192.36.27.4

Command does not work here
> echo -e 'AUTHENTICATE "pricemonitor1234"\r\nsignal NEWNYM\r\nQUIT' | nc 127.0.0.1 9051

Try to use Python to change the IP
> pip install stem

> python
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> from stem import Signal
>>> from stem.control import Controller
>>> with Controller.from_port(port=9051) as controller:
...     controller.authenticate()
...     controller.signal(Signal.NEWNYM)
...

That should work if the permission is right.
Config the Proxy
> cat /etc/privoxy/config
forward-socks5t / 127.0.0.1:9050 .

Start the Service
> sudo service privoxy start

Verify the IP
> curl -x 127.0.0.1:8118 http://icanhazip.com/
185.220.101.6

Verify with Request API
> python
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>>
>>> import requests
>>> response = requests.get('http://icanhazip.com/', proxies={'http': '127.0.0.1:8118'})
>>> response.text.strip()
'185.220.101.6'
