What is CartoDB?

[] (http://clinker.cartodb.net/jenkins/job/CartoDB-master-testing)

CartoDB is an open source tool that allows for the storage and visualization of geospatial data on the web.

It was built to make it easier for people to tell their stories by providing them with flexible and intuitive ways to create maps and design geospatial applications. CartoDB can be installed on your own server and we also offer a hosted service at cartodb.com.

If you would like to see some live demos, check out our videos on Vimeo. We hope you like it!

What can I do with CartoDB?

With CartoDB, you can upload your geospatial data (Shapefiles, GeoJSON, etc) using a web form and then make it public or private.

After it is uploaded, you can visualize it in a table or on a map, search it using SQL, and apply map styles using CartoCSS. You can even access it using the CartoDB API OVERVIEW and SQL API, or export it to a file.

In other words, with CartoDB you can make awesome maps and build powerful geospatial applications! Definitely check out the CartoDB Develop for interactive examples and code.

What are the components of CartoDB?

A User Interface for uploading, creating, editing, visualizing, and exporting geospatial data.
A geospatial database built on PostgreSQL and PostGIS 2.1
An SQL API for running SQL queries over HTTP with results formatted using GeoJSON and KML
A Map tiler that supports SQL and tile styling using CartoCSS
Authentication using OAuth if required

How do I install CartoDB?

This README is intended for Ubuntu 12.04. This doesn't mean that it can't be installed on other Linux versions or OSX systems, but that it's guaranteed to work only in Ubuntu 12.04. If anyone wants to share with us the installation process for any other system we will be more than happy to point it from this README. That said, there are also many successful installations on Amazon EC2, Linode, dedicated instances and development machines running OS X and Ubuntu 12.04+.

CartoDB is under heavy development. This means that this README can fail at some point. If see any issues, please let us know and we will fix them as soon as we can. Also if you feel that something is wrong or even missing we will be happy to fix it.

For any doubt about the process you can ask in our Google Group.

If you want to give it a try, download CartoDB by cloning this repository:

$ git clone --recursive https://github.com/CartoDB/cartodb.git

Or you can just download the CartoDB zip file.

Add CartoDB PPAs

First, retrieve new lists of packages:

sudo apt-get update

Install python software properties to be able to run add-apt-repository

sudo apt-get install python-software-properties

Add CartoDB Base PPA

sudo add-apt-repository ppa:cartodb/base

Add CartoDB GIS PPA

sudo add-apt-repository ppa:cartodb/gis

Add CartoDB Mapnik PPA

sudo add-apt-repository ppa:cartodb/mapnik

Add CartoDB Node PPA

sudo add-apt-repository ppa:cartodb/nodejs

Add CartoDB Redis PPA

sudo add-apt-repository ppa:cartodb/redis

Add CartoDB PostgreSQL PPA

sudo add-apt-repository  ppa:cartodb/postgresql-9.3

Resfresh repositories to use the PPAs

sudo apt-get update

Some dependencies

Installations assume you use UTF8, you can set it like this:

echo -e 'LANG=en_US.UTF-8\nLC_ALL=en_US.UTF-8' | sudo tee /etc/default/locale
source /etc/default/locale

make is required to compile sources

sudo apt-get install build-essential checkinstall

unp is required for archive file upload support

sudo apt-get install unp

zip is required for table exports

sudo apt-get install zip

Install GEOS

GEOS is required for geometry function support.

sudo apt-get install libgeos-c1 libgeos-dev

Install GDAL

GDAL is requires for raster support.

sudo apt-get install gdal-bin libgdal1-dev

Install JSON-C

JSON-C is required for GeoJSON support.

sudo apt-get install libjson0 python-simplejson libjson0-dev

Install PROJ

PROJ4 is required for reprojection support.

sudo apt-get install proj-bin proj-data libproj-dev

Install PostgreSQL

PostgreSQL is the relational database that powers CartoDB.

sudo apt-get install postgresql-9.3 postgresql-client-9.3 postgresql-contrib-9.3 postgresql-server-dev-9.3

plpython is required for Python support

sudo apt-get install postgresql-plpython-9.3

Currently there is an error with credential-based connections for development, and all connections must be performed using method "trust" inside config file pg_hba.conf.

cd /etc/postgresql/9.3/main
sudo vim pg_hba.conf

And change inside all local connections from peer/md5/... to trust.

Then restart postgres and you're done.

sudo /etc/init.d/postgresql restart

Install PostGIS

PostGIS is the geospatial extension that allows PostgreSQL to support geospatial queries. This is the heart of CartoDB!

cd /usr/local/src
sudo wget http://download.osgeo.org/postgis/source/postgis-2.1.7.tar.gz
sudo tar -xvzf postgis-2.1.7.tar.gz
cd postgis-2.1.7
sudo ./configure --with-raster --with-topology
sudo make
sudo make install

Finally, CartoDB depends on a geospatial database template named template_postgis.

sudo su - postgres
POSTGIS_SQL_PATH=`pg_config --sharedir`/contrib/postgis-2.1
createdb -E UTF8 template_postgis
createlang -d template_postgis plpgsql
psql -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis'"
psql -d template_postgis -c "CREATE EXTENSION postgis"
psql -d template_postgis -c "CREATE EXTENSION postgis_topology"
psql -d template_postgis -c "GRANT ALL ON geometry_columns TO PUBLIC;"
psql -d template_postgis -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;"
exit

Install cartodb-postgresql

cd /tmp
git clone https://github.com/CartoDB/pg_schema_triggers.git
cd pg_schema_triggers
sudo make all install PGUSER=postgres
sudo make installcheck PGUSER=postgres # to run tests
cd ..
git clone https://github.com/CartoDB/cartodb-postgresql.git
cd cartodb-postgresql
git checkout cdb
sudo make all install
sudo PGUSER=postgres make installcheck # to run tests

NOTE: if test_ddl_triggers fails it's likely due to an incomplete installation of schema_triggers. You need to add schema_triggers.so to the shared_preload_libraries setting in postgresql.conf :

$ sudo vim /etc/postgresql/9.3/main/postgresql.conf
...
shared_preload_libraries = 'schema_triggers.so'

$ sudo service postgresql restart # restart postgres

After this change the 2nd installcheck of cartodb-postresql should be OK.

Check https://github.com/cartodb/cartodb-postgresql/ for further reference

Install Ruby

We implemented CartoDB in the Ruby programming language, you'll need to install Ruby 1.9.3. You can use rbenv or a system install, up to you.

For rbenv:

rbenv

Follow the official guide on https://github.com/sstephenson/rbenv#installation

For bundler simply run:

gem install bundler

Install Node.js

The tiler API and the SQL API are both Node.js apps.

sudo add-apt-repository ppa:cartodb/nodejs-010
sudo apt-get update
sudo apt-get install nodejs

We currently run our node apps against version 0.10. You can install NVM to handle multiple versions in the same system.

Then you can install and use any version, for example:

nvm install v0.10
nvm use 0.10

Install Redis

Components of CartoDB, like Windshaft or the SQL API depend on Redis.

sudo apt-get install redis-server

Install Python dependencies

This needs to be done from the cartodb local copy. To install the Python modules that CartoDB depends on, you can use easy_install.

You need to have some dependencies installed before using pip:

sudo apt-get install python2.7-dev
sudo apt-get install build-essential
sudo su
apt-get install python-setuptools

easy_install pip
export CPLUS_INCLUDE_PATH=/usr/include/gdal
export C_INCLUDE_PATH=/usr/include/gdal
pip install --no-use-wheel -r python_requirements.txt
exit

If the previous step fails, try this alternative:

export CPLUS_INCLUDE_PATH=/usr/include/gdal
export C_INCLUDE_PATH=/usr/include/gdal
sudo pip install --no-install GDAL
cd /tmp/pip_build_root/GDAL
sudo python setup.py build_ext --include-dirs=/usr/include/gdal
sudo pip install --no-download GDAL

Install Mapnik

Mapnik is an API for creating beautiful maps. CartoDB uses Mapnik for creating and styling map tiles.

sudo apt-get install libmapnik-dev python-mapnik mapnik-utils

Install CartoDB SQL API

The CartoDB SQL API component powers the SQL queries over HTTP. To install it:

git clone git://github.com/CartoDB/CartoDB-SQL-API.git
cd CartoDB-SQL-API
git checkout master
npm install
cp config/environments/development.js.example config/environments/development.js

To run CartoDB SQL API in development mode, simply type:

node app.js development

Install Windshaft-cartodb

The Windshaft-cartodb component powers the CartoDB Maps API. To install it:

git clone git://github.com/CartoDB/Windshaft-cartodb.git
cd Windshaft-cartodb
git checkout master
npm install
cp config/environments/development.js.example config/environments/development.js

To run Windshaft-cartodb in development mode, simply type:

node app.js development

Install ImageMagick

sudo apt-get install imagemagick

Optional components

The following are not strictly required to run CartoDB:

Varnish

Varnish is a web application accelerator. Components like Windshaft use it to speed up serving tiles via the Maps API.

Add CartoDB Varnish PPA and install it:

sudo add-apt-repository  ppa:cartodb/varnish
sudo apt-get update
sudo apt-get install varnish=2.1.5.1-cdb1 #or any version <3.x

Varnish should allow telnet access in order to work with CartoDB, so you need to edit the /etc/default/varnish file and in the DAEMON_OPTS variable remove the -S /etc/varnish/secret \ line.

Raster import support

Raster importer needs raster2pgsql to be in your path. You can check whether it's available by running which raster2pgsql. If it's not, you should link it: $ sudo ln -s /usr/local/src/postgis-2.1.7/raster/loader/raster2pgsql /usr/bin/.

Access to temporary dir is also needed. Depending on your installation you might also need to run sudo chown 501:staff /usr/local/src/postgis-2.1.7/raster/loader/.libs (maybe replacing 501:staff with your installation /usr/local/src/postgis-2.1.7/raster/loader/ group and owner).

Install problems and common solutions

Installing the full stack might not always be smooth due to other component updates, so if you run into problems installing CartoDB, please check this list of problems and solutions first to see if your problem already happened in the past and somebody else found a workaround, solution or fix to it.

Install local instance of cold beer

Congratulations! Everything you need should now be installed. Celebrate by drinking a cold beer before continuing. :)

Running CartoDB

Time to run your development version of CartoDB. Let's suppose that we are going to create a development env and that our user/subdomain is going to be 'development'

export SUBDOMAIN=development

# Enter the `cartodb` directory.
cd cartodb

# Start redis, if you haven't done so yet
# Redis must be running when starting either the
# node apps or rails or running the ``create_dev_user script``
# NOTE: the default server port is 6379, and the default
#       configuration expects redis to be listening there
redis-server

# If it's a system wide installation
sudo bundle install

# If you are using rbenv simply run:
rbenv local 1.9.3-p551
bundle install

# Configure the application constants
cp config/app_config.yml.sample config/app_config.yml
vim config/app_config.yml

# Configure your postgres database connection details
cp config/database.yml.sample config/database.yml
vim config/database.yml

# Add entries to /etc/hosts needed in development
echo "127.0.0.1 ${SUBDOMAIN}.localhost.lan" | sudo tee -a /etc/hosts

# Create a development user
#
# The script will ask you for passwords and email
#
# Read the script for more informations about how to perform
# individual steps of user creation and settings management
#
sh script/create_dev_user ${SUBDOMAIN}

Start the resque daemon (needed for import jobs):

$ bundle exec script/resque

Finally, start the CartoDB development server on port 3000:

$ bundle exec rails s -p 3000

You should now be able to access http://<mysubdomain>.localhost.lan:3000 in your browser and login with the password specified above.

Note on tiling, SQL API and Redis

Please ensure CartoDB-SQL-API, Windshaft-cartodb, and Redis are all running for full experience.

Manual configuration is needed for the public/javascripts/environments/development.js file which configures Windshaft-cartodb tile server URLs.

Handy tasks

For a full list of CartoDB utility tasks:

bundle exec rake -T

Using foreman

You can also use foreman to run the full stack (cartodb server, sql api, tiler, redis and resque), using a single command: IMPORTANT: You need to install foreman by yourself. It's not included in the Gemfile. Run this:

bundle exec gem install foreman

bundle exec foreman start -p $PORT

where $PORT is the port you want to attach the rails server to.

How do I upgrade CartoDB?

See UPGRADE for instructions about upgrading CartoDB.

For upgrade of Windshaft-CartoDB and CartoDB-SQL-API see the relative documentation.
