Install vmware tools on ubuntu

fatgy (fat) — Mon, 29 Oct 2007 08:08:32 GMT

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

Setting up Ruby On Rails with PostgreSQL on Mac OS X 10.4.9

ntk () — Thu, 21 Jun 2007 21:25:53 GMT

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



 class People < ActiveRecord::Migration



    def self.up

      create_table :people do |table|

      # note that "id" is added implicitly, by default

        table.column :name, :string

        table.column :street1, :string

        table.column :street2, :string

        table.column :city, :string

        table.column :state, :string

        table.column :zip, :string

     end

    end



    def self.down

      drop_table :people 

    end

  end







rake db:migrate



ruby script/generate model Person  



#open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/app/models/person.rb  # file will be explained below



ruby script/console



>> ...

        entry = Person.new

        entry.name = "Name" 

        entry.street1 = "123 Somwhere" 

        entry.street2 = "" 

        entry.city = "Smallville" 

        entry.state = "KS" 

        entry.zip = "123456" 

        entry.save

        exit





# check newly created db table



psql `whoami`_development

SELECT * FROM people;

\q





# test

rake      # ... 0 failures, 0 errors



# create new controller

ruby script/generate controller People list view new edit





# edit /app/controllers/people_controller.rb

open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/app/controllers/people_controller.rb



  def view

   @person = Person.find(1)

  end







# edit /app/views/people/view.rhtml

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



# copy & paste & uncomment the following lines



#

#  

#    People#view

#    This page will display one person.

#    

#    <%= @person.name %>


#    <%= @person.street1 %>


#    <%= @person.street2 %>


#    <%= @person.city %>


#    <%= @person.state %>


#    <%= @person.zip %>


#    

#  

#





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

# open -e $HOME/Desktop/RubyOnRails-projects/`whoami`/app/models/person.rb



# class Person < ActiveRecord::Base

# 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

#ruby script/server --environment=development



# open a second shell window and go to ...  

open -a Safari http://localhost:3000/people/view
