Install vmware tools tar file on ubuntu from http://www.howtogeek.com/howto/ubuntu/install-vmware-tools-on-ubuntu-edgy-eft/
The first thing that is important is that you will need to know is
that you have to install the compilation utilities, which aren't
installed by default. Run these commands to get you started:

sudo apt-get install build-essential
sudo apt-get install linux-headers-`uname -r`

Now you'll want to navigate to the VM \ Install VMware Tools menu:

cp /cdrom/*.gz /tmp/
cd /tmp
tar xvzf VM*.gz
cd vmware*
sudo ./vmware-install.pl

This is a modified version of the Ruby on Rails Tutorial (TutorialStepOne, TutorialStepOnePostgresql, ...).

Log in to an admin user account and, if necessary, fix your command search path in $HOME/.bash_profile, $HOME/.bash_login or $HOME/.profile to include "/usr/local" and "/usr/local/sbin" (cf. Using /usr/local > Set The Path; echo $PATH | tr ":" "\n"). If there are no such files, just create them: touch $HOME/.bash_login && touch $HOME/.bashrc (ls -a | grep \.bash).

To avoid RubyGems loading issues it's no bad idea to add export RUBYOPT=rubygems to your $HOME/.bash_login file as well.

If you want your system path changes to take effect not only for you you can modify the global system path settings in the systemwide initialization files /private/etc/profile and /private/etc/bashrc accordingly.

To fix the paths of installed manual pages add the lines "MANPATH /usr/local/share/man" and "MANPATH /usr/local/man" to sudo nano +45 /usr/share/misc/man.conf (man -w | tr ":" "\n").


(USE THE FOLLOWING AT YOUR OWN RISK!)


REQUIREMENTS:

I. Xcode


II. PostgreSQL Database Server

Install this PostgreSQL Database Server package.

# test after installation
which psql     # /usr/local/bin/psql
psql --version     # psql (PostgreSQL) 8.2.3, contains support for command-line editing

Alternative installation: Getting PostgreSQL running for Rails on a Mac


III. Ruby 1.8.6, Ruby On Rails 1.2.3 & Mongrel 1.0.1

Building Ruby, Rails, Subversion, Mongrel, and MySQL on Mac OS X

To install both Mongrel & Mongrel Cluster use: sudo gem install -y mongrel mongrel_cluster (cf. Using Mongrel Cluster).

# test after installation
ruby -v     # ruby 1.8.6
rails -v     # Rails 1.2.3
gem list     # ... mongrel (1.0.1) ...

IV. ruby-postgres 0.7.1

sudo gem install -y ruby-postgres

As an alternative you may try Ruby on rails installer script for Mac OSX or choose to install via MacPorts as described in Installing Ruby on Rails and PostgreSQL on OS X, Second Edition or Installing Rails on Mac OS X Tiger (10.4.8). However, you then may have to change your system paths mentioned above accordingly.


1. create a database server

# first create a directory called PostgreSQL-db on your Desktop
mkdir -p $HOME/Desktop/PostgreSQL-db

# create a new db server called railsdb
/usr/local/bin/initdb -E UTF8 -D $HOME/Desktop/PostgreSQL-db/railsdb

# START DB SERVER
dir="$HOME/Desktop/PostgreSQL-db"; /usr/local/bin/pg_ctl -D $dir/railsdb -l $dir/railsdb/postgres.log start

# STOP DB SERVER
#dir="$HOME/Desktop/PostgreSQL-db"; /usr/local/bin/pg_ctl -D $dir/railsdb -l $dir/railsdb/postgres.log stop -m smart

# check
cat $HOME/Desktop/PostgreSQL-db/railsdb/pg_hba.conf

   ...
   # TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

   # "local" is for Unix domain socket connections only
   local   all         all                               trust
   # IPv4 local connections:
   host    all         all         127.0.0.1/32          trust
   # IPv6 local connections:
   host    all         all         ::1/128               trust

2. create PostgreSQL database

createdb `whoami`_development
#dropdb `whoami`_development

createdb `whoami`_test
#dropdb `whoami`_test

#createdb `whoami`_production
#dropdb `whoami`_production

3. set up your Rails project

cd $HOME/Desktop/RubyOnRails-projects
rails -d postgresql `whoami`
cd `whoami`

4. edit /config/database.yml

open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/config/database.yml

# just uncomment the following line
#encoding: UTF8 

5. make Rails & PostgreSQL work together

cd $HOME/Desktop/RubyOnRails-projects/`whoami`

ruby script/generate migration People

# edit /db/migrate/001_people.rb
# cf. http://wiki.rubyonrails.org/rails/pages/TutorialStepOneMigrations

open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/db/migrate/001_people.rb

        table.column :city, :string

    end
  end

        exit


# check newly created db table

  end



# edit /app/views/people/view.rhtml
open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/app/views/people/view.rhtml

# the file /app/models/person.rb explained (see above)

# end

# How does this know to map to the people table we created? ActiveRecord pluralizes the class name and looks for that 
# table in the database. This doesn’t just mean adding an ’s’. Irregular plural forms are also handled, so Rails knows 
# that the plural of ‘person’ is ‘people’. The rules for how it does this are described in the documentation
# (see http://wiki.rubyonrails.org/rails/pages/TutorialStepSix).

# test
rake

# start your Rails app
cd $HOME/Desktop/RubyOnRails-projects/`whoami`

#ruby script/server --environment=development

# open a second shell window and go to ...  
open -a Safari http://localhost:3000/people/view
