Cola: high-level distributed crawling framework


Cola is a high-level distributed crawling framework, used to crawl pages and extract structured data from websites. It provides simple and fast yet flexible way to achieve your data acquisition objective. Users only need to write one piece of code which can run under both local and distributed mode.


  • Python2.7 (Python3+ will be supported later)
  • Work on Linux, Windows and Mac OSX


The quick way:

pip install cola

Or, download source code, then run:

python setup.py install

Write applications

Documents will update soon, now just refer to the wiki or weibo application.

Run applications

For the wiki or weibo app, please ensure the installation of dependencies, weibo as an example:

pip install -r /path/to/cola/app/weibo/requirements.txt

Local mode

In order to let your application support local mode, just add code to the entrance as below.

from cola.context import Context
ctx = Context(local_mode=True)

Then run the application:

python __init__.py

Stop the local job by CTRL+C.

Distributed mode

Start master:

coca master -s [ip:port]

Start one or more workers:

coca worker -s -m [ip:port]

Then run the application(weibo as an example):

coca job -u /path/to/cola/app/weibo -r

Coca command

Coca is a convenient command-line tool for the whole cola environment.


Kill master to stop the whole cluster:

coca master -k


List all jobs:

coca job -m [ip:port] -l

Example as:

list jobs at master:
====> job id: 8ZcGfAqHmzc, job description: sina weibo crawler, status: stopped

You can run a job which shown in the list above:

coca job -r 8ZcGfAqHmzc

Actually, you don't have to input the complete job name:

coca job -r 8Z

Part of the job name is fine if there's no conflict.

You can know the status of a running job by:

coca job -t 8Z

The status like counters during running and so on will be output to the terminal.

You can kill a job by the kill command:

coca job -k 8Z


You can create an application by this command:

coca startproject colatest

Remember, help command will always be helpful:

coca -h


coca master -h
