Install Ruby on Rails in ubuntu10.10

1. Prepare the library used for installation

$ Sudo apt-Get install GCC g ++ build-essential libssl-dev libreadline5-dev zlib1g-dev Linux-headers-generic 

2. Download ruby1.9.2 source code compilation and Installation

$ wget ftp://ftp.ruby-lang.org//pub/ruby/1.9/ruby-1.9.2-p0.tar.gz
(If you ca n’t download, you can choose: http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2- p0.tar.bz2, http://ftp.ruby-lang.org/ pub / ruby / 1.9 / ruby-1.9.2-p0.zip)
$ tar -xvzf ruby-1.9.2-p0.tar.gz
$ cd ruby-1.9.2-p0 /
$ ./configure --prefix = / usr / local / ruby
$ make && sudo make install

3. Prepare Environment Variables

$ sudo gedit /etc/environment

Add Environment Variables

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/ruby/bin"

Note: You can also modify the/etc/profile file to add/usr/local/Ruby/bin.

 

4. Check Ruby Installation

$ Ruby-V 

Ruby 1.9.2p180 (Revision 30909) [i686-linux]

 

5. Create Association

$ sudo ln -s /usr/local/ruby/bin/ruby /usr/local/bin/ruby
$ sudo ln -s /usr/local/ruby/bin/gem /usr/bin/gem

If there is a symbolic connection gem under the/usr/bin/directory, delete the gem. Re:

$ Sudo ln-S/usr/local/Ruby/bin/gem/usr/bin/gem 

 

6. Install rails

$ sudo gem install tzinfo builder memcache-client rack rack-test erubis mail text-format bundler thor i18n
$ sudo gem install rack-mount
$ sudo gem install rails

Wait patiently ....

 

7. Check the rails Installation

$ Source/etc/environment $ rails-V 

Normally, rails 3.0.7

 

8. If you use a MySQL database

$sudo apt-get install mysql-server libmysqlclient-dev libmysql-ruby
$sudo gem install mysql

If the SQLite database is used:

$sudo apt-get install libsqlite3-dev build-essential
$sudo gem install sqlite3-ruby

 

9. If you want to install the spree framework

$ Sudo gem install spree 

 

10. Create an application for testing

For MySQL

$rails new xxx -d=mysql$cd xxx

Configure MySQL and open the config/database. yml file:

development:
adapter: mysql2
encoding: utf8
database: blog_development
pool: 5
username: root
password:
socket: /tmp/mysql.sock

Configure your username and password.
To use the spree framework, edit gemfile and add a gem 'spree'

$ bundle install
$ rake db: create
$ rails server // or $ rails s 

Open http: // localhost: 3000 in the browser.

Environment configuration is complete.
