Installing Ruby on Rails in FreeBSD with Postgres

Posted by Jason Noble on 09/02/2008 in FreeBSD, postgres, ruby, ruby on rails |

After setting up a minimal FreeBSD install, I want to get Ruby on Rails up and running.

Let’s see what’s available in the ports tree.

freebsd-vm# make search key=gem | grep Path: | grep ruby
Path: /usr/ports/audio/rubygem-mp3info
Path: /usr/ports/benchmarks/rubygem-railsbench
Path: /usr/ports/databases/ruby-dbd_pg
Path: /usr/ports/databases/ruby-rdbc1
Path: /usr/ports/databases/rubygem-activerecord
[...]
Path: /usr/ports/devel/ruby-gemfinder
Path: /usr/ports/devel/ruby-gems
Path: /usr/ports/devel/rubygem-activesupport
[...]
Path: /usr/ports/www/rubygem-scrubyt
Path: /usr/ports/www/rubygem-taggable
freebsd-vm# 

The ruby-gems port looks promising.

freebsd-vm# cd devel/ruby-gems
freebsd-vm# cat pkg-descr 
a package management framework for the Ruby programming language
An application or library is packaged into a gem, which is 
a single installation unit. 
RubyGems entirely manages its own filesystem space, rather 
than installing files into the "usual" places. This enables 
greater functionality and reliability. 

Using RubyGems, you can: 
- download and install Ruby libraries easily 
- not worry about libraries A and B depending on 
  different versions of library C 
- easily remove libraries you no longer use 
- have power and control over your Ruby platform!

freebsd-vm# 

Let’s install it. The install requires ruby to be installed, so it installs that for us (if it’s not currently installed). I enabled RDOC and DEBUG and disabled IPV6.
(This may take a while, go grab some coffee)

freebsd-vm# make install
=> rubygems-1.2.0.tgz doesn't seem to exist in /usr/ports/distfiles/ruby.
=> Attempting to fetch from http://rubyforge.rubyuser.de/rubygems/.
rubygems-1.2.0.tgz                            100% of  241 kB  138 kBps
===>  Extracting for ruby18-gems-1.2.0_1
[...]
If `gem` was installed by a previous RubyGems installation, you may need
to remove it by hand.

freebsd-vm# 

Now we need to install rails.

freebsd-vm# gem install rails

freebsd-vm# 

We need to install postgresql-server.

freebsd-vm# make search key=postgres | grep Path: | grep server
Path: /usr/ports/databases/aolserver-nspostgres
Path: /usr/ports/databases/erserver
Path: /usr/ports/databases/postgresql73-server
Path: /usr/ports/databases/postgresql74-server
Path: /usr/ports/databases/postgresql80-server
Path: /usr/ports/databases/postgresql81-server
Path: /usr/ports/databases/postgresql82-server
Path: /usr/ports/databases/postgresql83-server
Path: /usr/ports/finance/tinyerp-server
Path: /usr/ports/net/sipxcommserverlib
Path: /usr/ports/net-im/iserverd
freebsd-vm# 

Let’s install version 8.3. In the options that came up, I selected Build with PAM support and left the other defaults.

freebsd-vm# cd databases/postgresql83-server/
freebsd-vm# make install
cd /usr/ports/databases/postgresql83-server && make config;
[...]
      For more information, and contact details about the security
      status of this software, see the following webpage: 
http://www.postgresql.org/
freebsd-vm# 

We need to set postgres to run at startup.

freebsd-vm# echo 'postgresql_enable="YES"' >> /etc/rc.conf
freebsd-vm# 

Initialize the database.

freebsd-vm# /usr/local/etc/rc.d/postgresql initdb
The files belonging to this database system will be owned by user "pgsql".
This user must also own the server process.

The database cluster will be initialized with locale C.
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

    /usr/local/bin/postgres -D /usr/local/pgsql/data
or
    /usr/local/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start

freebsd-vm# 

Start up the database.

freebsd-vm# /usr/local/etc/rc.d/postgresql start
freebsd-vm#

Verify that postgres is working.

freebsd-vm# createdb test -U pgsql
freebsd-vm# dropdb test -U pgsql
freebsd-vm# 

There is a postgres GEM. Let’s install it.

freebsd-vm# gem install postgres
Building native extensions.  This could take a while...

1 gem installed

Installing RDoc documentation for postgres-0.7.9.2008.01.28...
freebsd-vm# 

Now we can create a rails application (I switched to a non-root user).

freebsd-vm$ rails -d postgresql sample_rails_app
      create  
      create  app/controllers
      create  app/helpers
      create  app/models
      create  app/views/layouts
      create  config/environments
[...]
      create  log/server.log
      create  log/production.log
      create  log/development.log
      create  log/test.log
freebsd-vm$  

Setup the postgres user for your application

freebsd-vm$ createuser --username pgsql
Enter name of role to add: sample_rails_app
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) n
freebsd-vm$ cd sample_rails_app/
freebsd-vm$ rake db:create
(in /usr/home/jasonn/sample_rails_app)
freebsd-vm$ 

Create a User scaffold

freebsd-vm$ script/generate scaffold User username:string password:string homedir:string ftp_disabled:boolean
      exists  app/models/
      exists  app/controllers/
      exists  app/helpers/
      create  app/views/users
      exists  app/views/layouts/
      exists  test/functional/
      exists  test/unit/
      exists  public/stylesheets/
      create  app/views/users/index.html.erb
      create  app/views/users/show.html.erb
      create  app/views/users/new.html.erb
      create  app/views/users/edit.html.erb
      create  app/views/layouts/users.html.erb
      create  public/stylesheets/scaffold.css
      create  app/controllers/users_controller.rb
      create  test/functional/users_controller_test.rb
      create  app/helpers/users_helper.rb
       route  map.resources :users
  dependency  model
      exists    app/models/
      exists    test/unit/
      exists    test/fixtures/
      create    app/models/user.rb
      create    test/unit/user_test.rb
      create    test/fixtures/users.yml
      create    db/migrate
      create    db/migrate/20080902231538_create_users.rb
freebsd-vm$ rake db:migrate
(in /usr/home/jasonn/sample_rails_app)
== 20080902231538 CreateUsers: migrating ======================================
-- create_table(:users)
NOTICE:  CREATE TABLE will create implicit sequence "users_id_seq" for serial column "users.id"

   -> 0.0645s
== 20080902231538 CreateUsers: migrated (0.0665s) =============================

freebsd-vm$ 

Start up the server and visit http://localhost:3000/users (you may need to substitute your IP address)

freebsd-vm$ script/server
=> Booting WEBrick...
=> Rails 2.1.0 application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options
[...]

Create some users, your Rails app is up and running.

    >I was just setting up postgres on a freebsd jail and had some problems connecting from rails, though psql worked fine. Turns out the problem is that you should use unix domain sockets so that it doesn't block the jail's IP, so I removed the host: localhost line from database.yml and it worked fine. Also, apparently pg is the new postgresql gem and the old postgres gem isn't developed anymore.
