ChiliProject w/Apache mod_rails (Passenger) Praxis/Gentoo Linux

This document describes how to install ChiliProject via Apache + Passenger or FastCGI, connected to a Subversion code repository with a PostgreSQL backend. The ChiliProject installation will be visible in a sub-directory at http://host/chili. The installation would be slightly different for an ChiliProject sub-domain.

Ruby Dependencies §

[ebuild  N     ] dev-ruby/bundler-1.0.18  USE="-test" RUBY_TARGETS="-ree18 ruby18" 169 kB
[ebuild  N     ] dev-ruby/mocha-0.9.12  USE="-doc -test" RUBY_TARGETS="-jruby -ree18 ruby18" 66 kB
[ebuild  N     ] dev-ruby/test-unit-2.1.2-r1

Then use bundle to bring the rest of the dependencies

bundle install --without=test sqlite mysql rmagick mysql2

Configure ChiliProject with the files ./config/configuration.yml and ./config/database.yml and session_store.rb

Migrate the datbase from Redmine (after confirming that the settings are the same)

RAILS_ENV=production bundle exec rake db:migrate

Via Passenger §

First, unmask (/etc/portage/package.keywords) the lastest version of Passenger (and dependencies), then install and configure.

=dev-ruby/daemon_controller-0.2.6 ~amd64
=www-apache/passenger-3.0.7 ~amd64

The packages in this example are specific versions, adjust as necessary for newer packages

~ # emerge -av www-apache/passenger

[ebuild  N     ] dev-libs/libev-4.04  USE="-static-libs" 461 kB
[ebuild  N    ~] dev-ruby/daemon_controller-0.2.6  USE="-test" RUBY_TARGETS="-ree18 ruby18" 22 kB
[ebuild     U ~] www-apache/passenger-3.0.7 [2.2.15] USE="-debug -doc -test%" RUBY_TARGETS="ruby18%*" 2,765 kB

Let that complete, then update /etc/conf.d/apache2 to have -D PASSENGER, similar to the following example.

APACHE2_OPTS="-D SSL -D PHP5 -D PASSENGER"

Adjust the Apache configuration for Passenger in /etc/apache2/modules.d/30_mod_passenger.conf as necessary (defaults may be OK). Then configure your ChiliProject similar to this example which shows ChiliProject in a sub-directory.

<Location /chili>

    Options Indexes -ExecCGI FollowSymLinks MultiViews
    # AllowOverride None
    Order allow,deny
    Allow from all

    # mod_rails
    # PassengerUser ChiliProject
    RailsEnv live
    RailsBaseURI /chili

    # environment.rb
    # ChiliProject::Utils::relative_url_root = "/chili"

</Location>

Configure ChiliProject §

Change ownership of necessary directores

~ # cd /var/lib/ChiliProject
~ # chown -R apache:apache files public/public_assets/ tmp/ /var/log/ChiliProject

Create / Update Configuration, edit database.yml, settings.yml as necessary. These files are located in /var/lib/ChiliProject/config, the names used represent an installed base, so multiple ChiliProjects can be served from the same code base.

~ # cat database.yml

live:
  adapter: postgresql
  database: my_ChiliProject
  host: sql.domain.tld
  username: ChiliProject
  password: ChiliProject_pw
  encoding: utf8

And we need to update some configuration data for ChiliProject, use the additional_environment.rb file.

~ # cat additional_environment.rb
config.action_controller.session = { :key => "_my_ChiliProject", :secret => "b8c98c891a2fcd9c268154f05b43c4" }

Use something like this command to generate a reasonable key.

~ # echo 'this is how I generate a key' | sha512sum |cut -b1-30
1eac0100cf4f009390fb3b683e8b8edd

Create the database

~ # psql
CREATE ROLE ChiliProject LOGIN ENCRYPTED PASSWORD 'my_password' NOINHERIT VALID UNTIL 'infinity';
CREATE DATABASE my_ChiliProject WITH ENCODING='UTF8' OWNER=ChiliProject;

And add the schema and base-data

~ # cd /var/lib/ChiliProject
RAILS_ENV=live rake db:migrate

When using FastCGI, we had to add this option to the end of environment.rb, possibiliy because of the sub-directory installation method.

ChiliProject::Utils::relative_url_root = "/ChiliProject"

Create Database in Sqlite3

~ # cat database.yml
production:
  adapter: sqlite3
  dbfile: /opt/company/var/ChiliProject.sqlite3

~ # rake db:migrate RAILS_ENV="live"

Create Database in PostgreSQL

~ # cat database.yml
live:
  adapter: pgsql
  dbfile: 

~ # rake db:migrate RAILS_ENV="live"

Watch Log Files

~ # tail -f /var/log/apache2/*log /var/log/ChiliProject/*log

Login as Admin

Login to the system using the default authentication of admin / admin. Update the password (in My Account) and then create the projects. Then go to the Administration section, load the default work flow and begin defining your environment.

Turn Down Logging Now

There is loads of logging in ChiliProject, turn this down to save disk I/O.

~ # cat additional_environment.rb
# This can be used if you don't have logrotate (should!)
# Logger.new(PATH,NUM_FILES_TO_ROTATE,FILE_SIZE)
# config.logger = Logger.new(config.log_path, 2, 1000000)

config.logger.level = Logger::INFO

Apache Proxy to Mongrel §

Much the same as above install ChiliProject and configure it properly. Update the Apache configuration to proxy requests to Mongrel services, make sure that ports and hostnames match up. This one has two services, balanced.

Start the Mongrel Services

~ # ruby /usr/bin/mongrel_rails start \
    -c /var/www/ChiliProject \
    -a localhost -p 10600 -e production \
    -d  --user www-data --group www-data \
    -P /var/run/mongrel/mongrel.10600.pid \
    -l /var/log/mongrel.10600.log

~ # ruby /usr/bin/mongrel_rails start \
    -c /var/www/ChiliProject \
    -a localhost -p 10601 -e production \
    -d  --user www-data --group www-data \
    -P /var/run/mongrel/mongrel.10601.pid \
    -l /var/log/mongrel.10601.log

Now configure Apache to Proxy requests to these two Mongrel services

	ProxyPass / balancer://ChiliProject_cluster/
	ProxyPassReverse / balancer://ChiliProject_cluster/

	<Proxy balancer://ChiliProject_cluster>
		BalancerMember http://localhost:10600
		BalancerMember http://localhost:10601
	</Proxy>
