*Lookyloo* is a web interface allowing to scrape a website and then displays a
|
|
tree of domains calling each other.
|
|
|
|
# What is that name?!
|
|
|
|
|
|
```
|
|
1. People who just come to look.
|
|
2. People who go out of their way to look at people or something often causing crowds and more disruption.
|
|
3. People who enjoy staring at watching other peoples misfortune. Oftentimes car onlookers to car accidents.
|
|
Same as Looky Lou; often spelled as Looky-loo (hyphen) or lookylou
|
|
In L.A. usually the lookyloo's cause more accidents by not paying full attention to what is ahead of them.

# Implementation details
|
|
|
|
This code is very heavily inspired by [webplugin](https://github.com/etetoolkit/webplugin) and adapted to use flask as backend.
|
|
|
|
The two core dependencies of this project are the following:
|
|
|
|
* [ETE Toolkit](http://etetoolkit.org/): A Python framework for the analysis and visualization of trees.
|
|
* [Splash](https://splash.readthedocs.io/en/stable/): Lightweight, scriptable browser as a service with an HTTP API
|
|
|
|
|
|
# Installation
|
|
|
|
**IMPORTANT**: Use [pipenv](https://pipenv.readthedocs.io/en/latest/)
|
|
|
|
**NOTE**: Yes, it requires python3.6+. No, it will never support anything older.
|
|
|
|
## Installation of Splash
|
|
|
|
You need a running splash instance, preferably on [docker](https://splash.readthedocs.io/en/stable/install.html)
|
|
|
|
```bash
|
|
sudo apt install docker.io
|
|
sudo docker pull scrapinghub/splash
|
|
sudo docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash --disable-ui --disable-lua --disable-browser-caches
|
|
# On a server with a decent abount of RAM, you may want to run it this way:
|
|
# sudo docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash --disable-ui -s 100 --disable-lua -m 50000 --disable-browser-caches
|
|
```
|
|
|
|
## Install redis
|
|
|
|
```bash
|
|
git clone https://github.com/antirez/redis.git
|
|
cd redis
|
|
git checkout 5.0
|
|
make
|
|
cd ..
|
|
```
|
|
|
|
## Installation of Lookyloo
|
|
|
|
```bash
|
|
git clone https://github.com/CIRCL/lookyloo.git
|
|
cd lookyloo
|
|
pipenv install
|
|
echo LOOKYLOO_HOME="'`pwd`'" > .env
|
|
```
|
|
|
|
# Run the app
|
|
|
|
```bash
|
|
pipenv run start.py
|
|
```
|
|
|
|
# Run the app in production
|
|
|
|
## With a reverse proxy (Nginx)
|
|
|
|
```bash
|
|
pip install uwsgi
|
|
```
|
|
|
|
## Config files
|
|
|
|
You have to configure the two following files:
|
|
|
|
* `etc/nginx/sites-available/lookyloo`
|
|
* `etc/systemd/system/lookyloo.service`
|
|
|
|
Copy them to the appropriate directories, and run the following command:
|
|
```bash
|
|
sudo ln -s /etc/nginx/sites-available/lookyloo /etc/nginx/sites-enabled
|
|
```
|
|
|
|
If needed, remove the default site
|
|
```bash
|
|
sudo rm /etc/nginx/sites-enabled/default
|
|
```
|
|
|
|
Make sure everything is working:
|
|
|
|
```bash
|
|
sudo systemctl start lookyloo
|
|
sudo systemctl enable lookyloo
|
|
sudo nginx -t
|
|
# If it is cool:
|
|
sudo service nginx restart
|
|
```
|
|
|
|
And you can open ```http://<IP-or-domain>/```
|
|
|
|
Now, you should configure [TLS (let's encrypt and so on)](https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04)
|
|
|
|
|
|
# Run the app with Docker
|
|
|
|
## Dockerfile
|
|
The repository includes a [Dockerfile](Dockerfile) for building a containerized instance of the app.
|
|
|
|
Lookyloo stores the scraped data in /lookyloo/scraped. If you want to persist the scraped data between runs it is sufficient to define a volume for this directory.
|
|
|
|
## Running a complete setup with Docker Compose
|
|
Additionally you can start a complete setup, including the necessary Docker instance of splashy, by using
|
|
Docker Compose and the included service definition in [docker-compose.yml](docker-compose.yml) by running
|
|
|
|
```
|
|
docker-compose up
|
|
```
|
|
|
|
After building and startup is complete lookyloo should be available at [http://localhost:5000/](http://localhost:5000/)
|
|
|
|
If you want to persist the data between different runs uncomment the "volumes" definition in the last two lines of
|
|
[docker-compose.yml](docker-compose.yml) and define a data storage directory in your Docker host system there.
