Ruby on Rails
Ruby on Rails is an open source web framework for developing database backed web applications. It is optimized for sustainable productivity of the programmer since it lets the programmer to write code by favouring convention over configuration.
Before installing Rails you should install Apache (or a preferred web server) and a database service such as MySQL. To install the Apache package, please refer to HTTPD - Apache2 Web Server. For instructions on installing and configuring a database service refer to MySQL documentation for example.
Once you have a web server (e.g. Apache) and a database service (e.g. MySQL) installed and configured, you are ready to install Ruby on Rails package.
To install the Ruby base packages and Ruby on Rails, you can enter the following command in the terminal prompt:
sudo apt install rails
/etc/apache2/sites-available/000-default.conf configuration file to setup your domains.
The first thing to change is the DocumentRoot directive:
Next, change the <Directory “/path/to/rails/application/public”> directive:
<Directory "/path/to/rails/application/public"> Options Indexes FollowSymLinks MultiViews ExecCGI AllowOverride All Order allow,deny allow from all AddHandler cgi-script .cgi </Directory>
You should also enable the mod_rewrite module for Apache. To enable mod_rewrite module, please enter the following command in a terminal prompt:
sudo a2enmod rewrite
Finally you will need to change the ownership of the
/path/to/rails/application/tmp directories to the user used to run the Apache process:
sudo chown -R www-data:www-data /path/to/rails/application/public sudo chown -R www-data:www-data /path/to/rails/application/tmp
If you need to compile your application assets run the following command in your application directory:
RAILS_ENV=production rake assets:precompile
With your database service in place you need to make sure your app database configuration is also correct. For example, if you are using MySQL your
config/database.yml should look like this:
# Mysql production: adapter: mysql2 username: user password: password host: 127.0.0.1 database: app
To finally create your application database and apply its migrations you can run the following commands from your app directory:
RAILS_ENV=production rake db:create RAILS_ENV=production rake db:migrate
That’s it! Now you have your Server ready for your Ruby on Rails application. You can daemonize your application as you want.
See the Ruby on Rails website for more information.
Also Agile Development with Rails is a great resource.
