Fork of jack_bunny

Fork of jack_bunny aimed to have a simple deployment and a tool that is ready for corporate use, improvements include:

• Cleaned up requirements.txt from indirect dependencies.
• Wrote Dockerfile and Makefile to easily run the app in a container.
• Cleaned pre-existing shortcuts (only kept Google and duckDuckGo), everything else is up to the person/company to setup based on need.

Runbook

Build and run docker locally

$ make run-docker

by default it runs on port 7015, customize it in the Makefile.

Stop and delete the docker container

$ make clear-docker

Attach to the running docker container:

$ make attach-docker

Usage

Installing on Google Chrome

• Open settings. Scroll down to the section where it says "Search engine".
• Click 'Manage search engines'. Next to 'Other search engines', click the ADD button.
• Name the 'Search engine' and 'Keyword' field whatever you want. Inside the URL field, paste this: http://[BUNNYLOL_DOMAIN]/q/?query=%s (clearly, use the domain you are running bunnylol from).
• Set this search engine to your default.
• Type 'help' into your address bar to see what commands are currently available.

Other browsers will likely have similar instructions.

Original README

jack_bunny

Inspired by Facebook's bunnylol search engine. The version that's currently open on github is pretty old and had some old dependencies so I thought it'd be easier to just write a more modern one. This one is still pretty basic and most likely has security holes that I'll run into later. Just wanted to get something off the ground and I'll add in more features time permitting.

Visit link to setup using this version that I'm hosting.

Commands

List of currently supported commands

• g [insert query] searching google
• p [insert class number] make a piazza search, kinda personalized just for jack lol
• fb [insert query] searching on facebook. defaults on fb homepage
• cpp [insert query] searches for syntactical cpp terms on cppreference.com
• w [insert query] searches wikipedia, defaults on english wikipedia page
• yt [insert query] make a youtube search. If not query is passed in, defaults to the youtube homepage
• gm [insert number from 0-n where n = number of gmail accounts - 1] opens up gmail. If no argument specificed, opens up the first account. Can open up alternative accounts with arguments
• help returns a list of usable commands

How to write your own commands

I think extending this is pretty intuitive for now. Just add in new methods to the Commands class. It might be a little confusing cause everything is happening in the jack_bunny.py file, I'll probably modularize this later when I have the time.

How to host your own server

I hosted this on an Amazon EC2 server, configured with nginx and gunicorn so I'll walk through the steps I went through.

The first step is to clone this repo on the server you want to run this on and download all the dependencies. These should all be in the requirements.txt file so something like pip3 install -r /path/to/requirements.txt should work. If you run into any issues, the only python libraries this really uses are flask and wikipedia so downloading those should resolve any problems.

There are additional packages you need to host this. The first is nginx. To install this, you can simply use sudo apt-get install nginx. We will also need to install gunicorn and to do this you can use pip3 install gunicorn.

The idea behind this is that we will use gunicorn to run this on the localhost on some unused port. We will then use nginx as a reverse proxy so that it will hand off the request it received to gunicorn and then gunicorn will serve that to nginx which will the be given to the user.

So how do we do this?

First we want to get gunicorn running. The command to run is gunicorn jack_bunny:app -p jack_bunny.pid -D. In this command, jack_bunny represents the file name without the .py and app represents the Flask app. We add the -D tag so that this will be running in the background, even when we close out. the -p jack_bunny.pid saves the process_id to this file so if you want to kill this process you can just kill -9 it.

Now we just have to setup nginx because this is still only running locally.

I first created this new config file at /etc/nginx/sites-available/jack_bunny

# /etc/nginx/sites-available/jack_bunny

# Redirect www.[insert server name].com to [insert server name].com
server {
        server_name www.[insert server name].com;
        rewrite ^ http://[insert server name].com/ permanent;
}

# Handle requests to [insert server name].com on port 80
server {
        listen 80;
        server_name [insert server name].com;

                # Handle all locations
        location / {
                        # Pass the request to Gunicorn
                proxy_pass http://127.0.0.1:8000;

                # Set some HTTP headers so that our app knows where the
                # request really came from
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

Then I created symlink here.

$ sudo ln -s \
/etc/nginx/sites-available/jack_bunny \
/etc/nginx/sites-enabled/jack_bunny

After restarting nginx you should be good to go!

If you run into some nginx configuration problems, check the error logs to see what could be going wrong. One thing that I ran into was my server name was too long and this gave me some server hash name error. I resolved this by adding the line server_names_hash_bucket_size 128; to my nginx config file here /etc/nginx/nginx.conf.

There are a bunch of ways to deploy a flask app on a server so oyou don't have to do this. I just found this to be the fastest way. For reference this is the guide I followed, it's pretty detailed.
