What to do?  (s)witch, (i)gnore, (w)ipe, (b)ackup s

Choose "switch" and let's hope it works.

Install Mapnik

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

Install CartoDB SQL API

cd ~

git clone git://github.com/CartoDB/CartoDB-SQL-API.git
cd CartoDB-SQL-API
git checkout master
npm install

Create config files:

cd config/environments/
cp development.js.example development.js

Install tile server

cd ~

git clone git://github.com/CartoDB/Windshaft-cartodb.git
cd Windshaft-cartodb
git checkout master
npm install

Config files:

cd config/environments/
cp development.js.example development.js

Install Ruby gems and configure the Rails app

export SUBDOMAIN=development

cd ~/cartodb20

Redis must be running before starting the Node applications or Rails, and also before running the create_dev_user script:

redis-server &

Install dependency for nokogiri:

sudo apt-get install libxslt-dev

Install gems for the Rails app:

rvm use 1.9.2@cartodb --create && bundle install

Set postgres password:

sudo -u postgres psql
\password
(Set password)
\q

Create/edit config files:

cp config/app_config.yml.sample config/app_config.yml

For database set postgres password in the config file:

cp config/database.yml.sample config/database.yml
nano config/database.yml

Create the development user:

sh script/create_dev_user ${SUBDOMAIN}

(Enter passwords and email)

To be able to use subdomain as user (also see below):

echo "127.0.0.1 ${SUBDOMAIN}.localhost.lan" | sudo tee -a /etc/hosts

To be able to login, the username has to be the same as the subdomain name, which has been defined above in ${SUBDOMAIN} = development.

To achieve this you have to setup /etc/hosts in such a way that you can reach cartodb through a development.* subdomain:

What worked for me:

Add to /etc/hosts of the machine your calling carto from:

192.168.56.10   development.localhost.lan

I also changed this in cartodb20/config/app_config.yml, but I don't know if it's really necessary...:

developers_host:    'http://development.localhost.lan:3000'

More configuring to get things to work

In Windshaft config/environments/development.js change:

host: ''  //so the tiler listens to all IP addresses, not just localhost

mapnik_version: '2.1.1' //to fool it into believing it has this version, needed because CartoCSS is based on this version of Mapnik

In SQL API config/environments/development.js change:

module.exports.node_host    = '';  //idem

In cartodb20/config/app_config.yml:

private:
  protocol:      'http'  // want met https werkt het niet

In /etc/postgresql/9.1/main/pg_hba.conf, set auth method to "trust":

host     all             all             127.0.0.1/32            trust
local    all             all                                     trust

to prevent error "password authentication failed for user publicuser" (source: CartoDB/Windshaft-cartodb#61).

Change domain names!

A.o here: Windshaft/config/environments/development.js:

,sqlapi: {
    protocol: 'http',
    host: 'qmaps.nl',

PGBouncer

PGBouncer has to be installed otherwise only the first import will work, see CartoDB/cartodb#51

sudo apt-get install pgbouncer

In /etc/pgbouncer/pgbouncer.ini:

[databases]
* = host=127.0.0.1 port=5432

auth_type = trust

In /etc/pgbouncer/userlist.txt:

"postgres" "passwd"
"development_cartodb_user_1" "passwd"
"publicuser"
"tileuser"

In /etc/default/pgbouncer set

START=1

Change port to 6432 in cartodb20/SQL API/Windshaft configuration files!

sudo service pgbouncer restart

Make shp2pgsql accessible through the path

To make shp2pgsql available on the path:

sudo ln -s /usr/local/src/postgis-2.0.2/loader/shp2pgsql /usr/bin/shp2pgsql

Upgrade database schema if needed

Upgrade to 2.1.2:

bundle exec rake cartodb:db:create_importer_schema

Run!

Start all services using foreman:

bundle exec foreman start -p $PORT

Production deployment

Rails

Install Apache:

sudo apt-get install apache2

Install Passenger, see http://www.modrails.com/documentation/Users%20guide%20Apache.html

gem install passenger

Make phusion accesible to webserver:

passenger-config --root

chmod o+x /home/phusion/.rvm/gems/ruby-1.9.3-p362/gems/passenger-x.x.x
chmod o+x /home/phusion/.rvm/gems/ruby-1.9.3-p362/gems
chmod o+x /home/phusion/.rvm/gems/ruby-1.9.3-p362
chmod o+x /home/phusion/.rvm/gems
chmod o+x /home/phusion/.rvm
chmod o+x /home/phusion

(Paths will be different.)

Install dependencies for Passenger:

sudo apt-get install apache2-threaded-dev libapr1-dev libaprutil1-dev

Install and configure the Apache module:

passenger-install-apache2-module

Create Apache config files for Passenger (see http://www.modrails.com/documentation/Users%20guide%20Apache.html#working_with_apache_conf).

Create /etc/apache2/mods-available/passenger.load containing:

LoadModule passenger_module /home/quser/.rvm/gems/ruby-1.9.2-p320@cartodb/gems/passenger-4.0.10/buildout/apache2/mod_passenger.so

Create /etc/apache2/mods-available/passenger.conf containing:

PassengerRoot /home/quser/.rvm/gems/ruby-1.9.2-p320@cartodb/gems/passenger-4.0.10
PassengerDefaultRuby /home/quser/.rvm/wrappers/ruby-1.9.2-p320@cartodb/ruby

Enable the module!

sudo a2enmod passenger

Suppose you have a Rails application in /somewhere. Add a virtual host to your Apache configuration file and set its DocumentRoot to /somewhere/public:

Add to /etc/apache2/sites-available/default:

<VirtualHost *:80> ServerName www.yourhost.com # !!! Be sure to point DocumentRoot to 'public'! DocumentRoot /somewhere/public
<Directory /somewhere/public> # This relaxes Apache security settings. AllowOverride all # MultiViews must be turned off. Options -MultiViews

Restart Apache:

sudo service apache2 restart

Node.js

See https://www.exratione.com/2013/02/nodejs-and-forever-as-a-service-simple-upstart-and-init-scripts-for-ubuntu/

Globally install the Node module "forever":

sudo npm -g install forever

Create init script

sudo nano /etc/init.d/cartodb-windshaft

with contents:

#
# An example init script for running a Node.js process as a service
# using Forever as the process monitor. For more configuration options

Make executable:

chmod a+x /etc/init.d/cartodb-windshaft

Update the runlevel configurations:

sudo update-rc.d cartodb-windshaft defaults

Start the service!

sudo service cartodb-windshaft start

Idem for the SQL API!

Redis

Follow the steps under "Installing Redis more properly" at http://redis.io/topics/quickstart

sudo mkdir /etc/redis
sudo mkdir /var/redis
sudo mkdir /var/redis/6379

Create /etc/init.d/redis_6379 with contents:

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
 
REDISPORT=6379
EXEC=/usr/bin/redis-server
CLIEXEC=/usr/bin/redis-cli
 
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"
 
case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

Create /etc/redis/6379.conf from default config file and change the following:

  • Set daemonize to yes (by default it is set to no).
  • Set the pidfile to /var/run/redis_6379.pid (modify the port if needed).
  • Change the port accordingly. In our example it is not needed as the default port is already 6379.
  • Set your preferred loglevel.
  • Set the logfile to /var/log/redis_6379.log
  • Set the dir to /var/redis/6379 (very important step!)

Make init script executable:

sudo chmod a+x /etc/init.d/redis_6379

Start the service!

sudo service redis_6379 start

Setup SSL

Create /etc/apache2/sites-available/default-ssl with something like:

<VirtualHost *:443>
    ServerName carto.qmaps.nl
    ServerAlias carto.qmaps.nl
    # !!! Be sure to point DocumentRoot to 'public'!
    DocumentRoot /home/quser/cartodb20/public
    RailsEnv production
    PassengerSpawnMethod direct

    #TODO later: SSL options

    <Directory /home/quser/cartodb20/public>
        # This relaxes Apache security settings.
        AllowOverride all
        # MultiViews must be turned off.
        Options -MultiViews
    </Directory>
</VirtualHost>

Enable SSL module:

sudo a2enmod ssl

Enable SSL site:

sudo a2ensite default-ssl

In /etc/apache2/ports.conf add NameVirtualHost 443:

<IfModule mod_ssl.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

Setup SSL certificate.... More...?
