Camper - Barcamp-Tools

Requirements

• Python 2.7
• virtualenv
• MongoDB
• Etherpad Lite with admin access

For development (esp. JS/CSS):

• node.js

Installation

Create a virtual environment

virtualenv .
source bin/activate

Clone camper into a directory inside, e.g. camper/

git clone https://github.com/comlounge/camper.git camper

Develop camper

cd camper/
python setup.py develop
cd ..

Configuration

Copy example config files into the venv root

cp -r camper/etc .

Don't forget to adjust settings, like mongodb host/port or location of image files.

Also go to mapbox.com and create an API key and a map key.

For development make sure you have dev.localhost assigned to 127.0.0.1 in /etc/hosts so that cookies can be saved (localhost does not work on many browsers).

The file config.ini contains all the configuration variables, the file dev.ini is prepared for development. The file scripts.ini is the same as dev.ini but has debug switched off. This one is used for running scripts like the one below for creating a user.

Note: you have to configure the mongodb endpoint twice, for the main app and for the userbase module as they do not share a database connection.

Hooking up nginx

In order to make run behind nginx in addition with an etherpad server you can use this configuration as a start:

server {

    listen 80;
    
    server_name mydomain;

    access_log /var/log/nginx/mydomain.access.log rt_cache;
    error_log /var/log/nginx/mydomain.error.log;

    add_header X-Proxy-Cache $upstream_cache_status;

    # we only use the pads here and route it to the etherpad lite instance
    # which runs on port 9999 in our case
    location /_pads/ {

        proxy_pass             http://127.0.0.1:9999/;
        proxy_set_header       Host $host;
        proxy_pass_header Server;

        # be carefull, this line doesn't override any proxy_buffering on set in a conf.d/file.conf
        proxy_buffering off;
        proxy_set_header X-Real-IP $remote_addr;  # http://wiki.nginx.org/HttpProxyModule
        proxy_set_header X-Forwarded-For $remote_addr; # EP logs to show the actual remote IP
        proxy_set_header X-Forwarded-Proto $scheme; # for EP to set secure cookie flag when https is used
        proxy_set_header Host $host;  # pass the host header
        proxy_http_version 1.1;  # recommended with keepalive connections

        # WebSocket proxying - from http://nginx.org/en/docs/http/websocket.html
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }

    # the camper instance runs on 9998
    location / {
        proxy_pass             http://127.0.0.1:9998/;
        proxy_set_header       Host $host;
        proxy_pass_header Server;

        # be carefull, this line doesn't override any proxy_buffering on set in a conf.d/file.conf
        proxy_buffering off;
        proxy_set_header X-Real-IP $remote_addr;  # http://wiki.nginx.org/HttpProxyModule
        proxy_set_header X-Forwarded-For $remote_addr; # EP logs to show the actual remote IP
        proxy_set_header X-Forwarded-Proto $scheme; # for EP to set secure cookie flag when https is used
        proxy_set_header Host $host;  # pass the host header                                                   
        proxy_set_header       X-Url-Scheme https;
        proxy_http_version 1.1;  # recommended with keepalive connections                                                    

        # WebSocket proxying - from http://nginx.org/en/docs/http/websocket.html
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}


map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

Create a user and give it the admin role::

bin/um -f etc/scripts.ini add <username> <email> <password>
bin/um -f etc/scripts.ini permissions <username> admin,userbase:admin

Start the development server

bin/paster serve etc/camper.ini

If you do development you might want to add a --reload at the end.
