== | === Alternative to manual installation === | ||
Some users may prefer to skip manual installation by using the unofficial | |||
http://www. | pre-integrated [http://www.turnkeylinux.org/rails TurnKey Ruby on Rails Appliance] based on Ubuntu LTS. | ||
=== Intro Ubuntu 8.04 === | |||
These instructions are for Ubuntu 8.04 LTS (hardy). Instead of using <code><nowiki>apt</nowiki></code> we use gems because of what ReinH put best... | |||
=== | |||
'' | '' | ||
<ReinH> Let gems manage your rails package otherwise gem and apt-get will start fighting like Spock and Captain Kirk in | <ReinH> Let gems manage your rails package otherwise gem and apt-get will start fighting like Spock and Captain Kirk in Amok Time. If you haven't seen that episode, trust me: you don't want that. | ||
'' | '' | ||
=== Intro Ubuntu 9.04 ... Apache2.2 tested only === | |||
<pre><nowiki>sudo apt-get install ruby | Slight additions from 8.04 documentation... | ||
* Using Passenger ( mod_rails ) may be required, it was for me. see http://www.modrails.com/documentation/Users%20guide.html Do NOT try a manual installation, use gems only. | |||
* Do the minimum Ruby installation from Debian packages ( apt-get | Aptitude | Synaptic ). First install Ruby and Apache and rubygems as described below using Debian packages, then use gems only for the other Ruby-based applications. | |||
* Use an Apache vhost configuration that puts the myapp/public directory at the document root. see http://httpd.apache.org/docs/2.2/vhosts/name-based.html | |||
* Using an .htaccess file in the myapp/public directory may be required. | |||
* Using fastcgi or fcgid Apache modules is not required, and may not work at all. | |||
* The Rails group is another good place to ask for assistance... http://groups.google.com/group/rubyonrails-talk | |||
* The Rails guide is excellent... http://guides.rubyonrails.org/index.html | |||
=== Get Ruby === | |||
<pre><nowiki> | |||
sudo apt-get install ruby-full build-essential | |||
</nowiki></pre> | </nowiki></pre> | ||
Note that `ruby-full` will install emacs and a slew of other non-essential packages. You can install all the necessary packages with this command: | |||
<pre><nowiki> | |||
< | sudo aptitude install ruby build-essential libopenssl-ruby ruby1.8-dev | ||
</nowiki></pre> | |||
<pre><nowiki>wget http://rubyforge.org/frs/download.php/34638/rubygems-1.1.0.tgz | === Server Installation === | ||
Now you have ruby, you already got a server included, WEBrick. You may settle with that, also because the installation is much easier, and reboots are faster. But it lacks the configuration options that apache and lighttpd offer. So if you want to have RubyOnRails running on apache or lighttpd, make sure you have installed these first. | |||
==== Apache ==== | |||
<pre><nowiki> | |||
sudo apt-get install apache2 apache2-mpm-prefork apache2-prefork-dev | |||
</nowiki></pre> | |||
WARNING: libapache2-mod-passenger installation uninstalls libapache2-mod-php5 and php5. | |||
==== Apache + Mongrel ==== | |||
Mongrel Cluster works as a proxy service under Apache (no additional modification is required). | |||
<pre><nowiki> | |||
sudo a2enmod proxy | |||
sudo a2enmod proxy_http | |||
sudo a2enmod rewrite | |||
sudo /etc/init.d/apache2 restart | |||
sudo apt-get install mongrel | |||
</nowiki></pre> | |||
[http://wiki.rubyonrails.org/deployment/apache-mongrel Rails Wiki - Apache + Mongrel] | |||
[http://mongrel.rubyforge.org/wiki/Apache RubyForge Mongrel - Apache Best Practice Deployment] | |||
==== Lighttpd ==== | |||
Preparing the house: | |||
<pre><nowiki> | |||
sudo apt-get install lighttpd libfcgi-ruby1.8 | |||
</nowiki></pre> | |||
=== Installing RubyGems === | |||
The link below is to a specific version of RubyGems (version 1.1). You can get a later version from http://rubyforge.org/frs/?group_id=126, but it should not be really necessary because we ask RubyGems to update itself at the end. But to make it more complete, a description of RubyGems 1.2 is also included, below the install instructions of RubyGems 1.2. | |||
==== RubyGems via apt ==== | |||
<pre><nowiki> | |||
sudo apt-get install rubygems | |||
</nowiki></pre> | |||
''As of July 27, 2009, RubyGems 1.3.1 is installed via apt.'' | |||
To make gem work properly you should write gem's path to PATH add to ~/.bashrc: | |||
<pre><nowiki> | |||
export PATH=/var/lib/gems/1.8/bin:$PATH | |||
</nowiki></pre> | |||
To export path once just enter previous code to bash. | |||
==== RubyGems 1.1.0 ==== | |||
<pre><nowiki> | |||
wget http://rubyforge.org/frs/download.php/34638/rubygems-1.1.0.tgz | |||
tar xzvf rubygems-1.1.0.tgz | tar xzvf rubygems-1.1.0.tgz | ||
cd rubygems-1.1.0 | cd rubygems-1.1.0 | ||
sudo ruby setup.rb | sudo ruby setup.rb | ||
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem | |||
sudo gem update --system | sudo gem update --system | ||
</nowiki></pre> | </nowiki></pre> | ||
2 | ==== RubyGems 1.2.0 ==== | ||
<pre><nowiki>sudo | <pre><nowiki> | ||
wget http://rubyforge.org/frs/download.php/38646/rubygems-1.2.0.tgz | |||
tar xzvf rubygems-1.2.0.tgz | |||
cd rubygems-1.2.0 | |||
sudo ruby setup.rb | |||
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem | |||
sudo gem update --system | |||
</nowiki></pre> | |||
The below error is sometimes encountered after running sudo gem update --system. | |||
<pre><nowiki> | |||
/usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError) | |||
</nowiki></pre> | |||
To fix that error follow the below instructions. | |||
<pre><nowiki> | |||
sudo gedit /usr/bin/gem | |||
In the file find: | |||
require 'rubygems' | |||
Add the following line below the above line: | |||
require 'rubygems/gem_runner' | |||
</nowiki></pre> | |||
==== RubyGems 1.3.1 Ubuntu 8.04 ==== | |||
<pre><nowiki> | |||
wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz | |||
tar xzvf rubygems-1.3.1.tgz | |||
cd rubygems-1.3.1 | |||
sudo ruby setup.rb | |||
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem | |||
sudo gem update --system | sudo gem update --system | ||
</nowiki></pre> | </nowiki></pre> | ||
3 | ==== RubyGems 1.3.1 Ubuntu 9.04 ==== | ||
<pre><nowiki>sudo gem install rails | <pre><nowiki> | ||
sudo apt-get install rubygems1.8 | |||
sudo gem install rubygems-update | |||
sudo update_rubygems note: this will clean out your gems! | |||
</nowiki></pre> | |||
=== Installing rails === | |||
We can now use RubyGems to install rails: | |||
<pre><nowiki> | |||
sudo gem install rails | |||
</nowiki></pre> | </nowiki></pre> | ||
Also we can install rails from apt ( not suggested for Ubuntu 9.04 ) | |||
<pre><nowiki> | |||
<pre><nowiki> | |||
sudo apt-get install rails | |||
</nowiki></pre> | </nowiki></pre> | ||
I think, it would be better to install rails with gem. | |||
If you encounter difficulties installing fcgi (fastcgi) via gem, this might help: | |||
<pre><nowiki> | |||
<pre><nowiki>sudo | sudo aptitude install libfcgi-dev | ||
</nowiki></pre> | </nowiki></pre> | ||
=== Preparing for your first rails app === | |||
<pre><nowiki> | Configuration of the webserver also assumes you have by then a rails application set up. Simply enter to get that done (it will create you a first test page): | ||
Default (sqlite3 backend): | |||
<pre><nowiki> | |||
rails /home/myuser/www/mynewapp | |||
</nowiki></pre> | </nowiki></pre> | ||
For a mysql back-end. | |||
Run this one, if you installed rails with gem: | |||
<pre><nowiki> | |||
rails /home/myuser/www/mynewapp -d mysql | |||
<pre><nowiki> | |||
</nowiki></pre> | </nowiki></pre> | ||
Run this one, if you installed rails with apt: | |||
<pre><nowiki> | |||
<pre><nowiki> | rails /home/myuser/www/mynewapp -D mysql | ||
</nowiki></pre> | </nowiki></pre> | ||
You will see a bunch of stuff on the shell... that should be fine (unless you see a error message). That created the rails folder with all the stuff, so now you should have something like have: /home/myuser/www/mynewapp/public | |||
=== | === Configure the server === | ||
==== WEBrick (Ruby's server) ==== | |||
No configuring needed, everything is ready to create your first application. You can even try this step before you try launching your application via apache or lighttpd: | |||
<pre><nowiki> | |||
$cd /home/myuser/www/mynewapp | |||
$ruby script/server | |||
=> Booting WEBrick... | |||
=> Rails 2.1.0 application started on http://0.0.0.0:3000 | |||
=> Ctrl-C to shutdown server; call with --help for options | |||
[2008-07-28 04:39:17] INFO WEBrick 1.3.1 | |||
[2008-07-28 04:39:17] INFO ruby 1.8.6 (2007-09-24) | |||
[2008-07-28 04:39:17] INFO WEBrick::HTTPServer#start: pid=6860 port=3000 | |||
</nowiki></pre> | </nowiki></pre> | ||
If you | Your application is now responding at `http://0.0.0.0:3000`; press Ctrl+C to stop the web server. If you get errors related to the database, '''you might need to install a DB connector, or create a database.''' Edit this in `$YOUR_RAILS_DIRECTORY/config/database.yml` | ||
<pre><nowiki>sudo apt-get install | Install the sqlite3 connector: | ||
<pre><nowiki> | |||
sudo apt-get install libsqlite3-dev | |||
sudo gem install sqlite3-ruby | |||
</nowiki></pre> | </nowiki></pre> | ||
Or install the MySQL database and it's connector: | |||
<pre><nowiki>sudo gem install mysql | <pre><nowiki> | ||
sudo apt-get install mysql-server mysql-client | |||
sudo apt-get install libmysql-ruby libmysqlclient-dev | |||
sudo gem install mysql | |||
</nowiki></pre> | </nowiki></pre> | ||
Or install the [[UbuntuHelp:PostgreSQL|PostgreSQL]] database and it's connector: | |||
<pre><nowiki> | |||
sudo apt-get install postgresql-server postgresql-client | |||
sudo apt-get install libpq-dev | |||
sudo gem install pg | |||
</nowiki></pre> | </nowiki></pre> | ||
==== Apache ==== | |||
<pre><nowiki>sudo apt-get install | Run the following to install passenger, an apache module that adds support for running rails apps within apache: | ||
<pre><nowiki> | |||
sudo gem install passenger | |||
sudo apt-get install apache2-dev libapr1-dev libaprutil1-dev | |||
sudo passenger-install-apache2-module | |||
</nowiki></pre> | </nowiki></pre> | ||
WARNING: libapache2-mod-passenger installation uninstalls libapache2-mod-php5 and php5. | |||
Now you have to configure apache to point to the passenger module. Simply copy the following suggested code from the <code><nowiki>passenger-install-apache2-module</nowiki></code> installation to the end of your Apache configuration file, which can be accessed by typing in the command <code><nowiki>sudo gedit /etc/apache2/apache2.conf</nowiki></code>: | |||
/etc/apache2/ | (if you are using RubyGems 1.1): | ||
<pre><nowiki> | <pre><nowiki> | ||
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-1.0.3/ext/apache2/mod_passenger.so | |||
RailsSpawnServer /usr/lib/ruby/gems/1.8/gems/passenger-1.0.3/bin/passenger-spawn-server | |||
RailsRuby /usr/bin/ruby1.8 | |||
</nowiki></pre> | </nowiki></pre> | ||
(if you are using RubyGems 1.2): | |||
<pre><nowiki> | |||
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3/ext/apache2/mod_passenger.so | |||
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3 | |||
PassengerRuby /usr/bin/ruby1.8 | |||
</nowiki></pre> | </nowiki></pre> | ||
(if you are using RubyGems 1.3.1): | |||
<pre><nowiki> | |||
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.6/ext/apache2/mod_passenger.so | |||
<pre><nowiki> | PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.6 | ||
PassengerRuby /usr/bin/ruby1.8 | |||
</nowiki></pre> | </nowiki></pre> | ||
(if you are using RubyGems 1.3.6 and Ubuntu 9.10): | |||
<pre><nowiki> | |||
LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so | |||
PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.11 | |||
PassengerRuby /usr/local/bin/ruby | |||
</nowiki></pre> | </nowiki></pre> | ||
Now you should point apache to the location of your Ruby app. Create something like this in /etc/apache2/sites-available/ror.myhost.com | |||
<pre><nowiki> | <pre><nowiki> | ||
<VirtualHost *> | <VirtualHost *> | ||
ServerName ror.myhost.com | |||
DocumentRoot /home/myuser/www/mynewapp/public | |||
RailsEnv development #It's optional string, but my rails app didn't work properly without it. | |||
</VirtualHost> | |||
</nowiki></pre> | |||
Alternatively, you could run rails in a specific sub uri of your current host, e.g. localhost. First, make a symbolic link to your rails public folder from with var/www (or wherever you have the root of your apache www folder), e.g.: | |||
<pre><nowiki> | |||
ln -s /home/myuser/www/mynewapp/public /var/www/mynewapp | |||
</nowiki></pre> | |||
In case of localhost (which is the default host with a fresh ubuntu/apache install) edit <code><nowiki>default</nowiki></code> in <code><nowiki>/etc/apache2/sites-available</nowiki></code> and add: | |||
<pre><nowiki> | |||
RailsBaseURI /mynewapp | |||
</nowiki></pre> | |||
''murb: I had to add <code><nowiki>RailsEnv development</nowiki></code> as well to get around the 'no route found to match "/rails/info/properties" with {:method=>:get}' warning... (can someone elaborate on why?)'' apparently this is because /info/properties is buggy and no longer supported: http://www.ruby-forum.com/topic/161924 | |||
Save, and enable the rewrite module for apache, and register this site... and finally, restart apache. | |||
<pre><nowiki> | |||
sudo a2enmod rewrite | |||
sudo a2ensite ror.myhost.com | |||
sudo /etc/init.d/apache2 restart | |||
</nowiki></pre> | |||
==== An Alternate Apache Configuration with a named vhost Ubuntu 9.04 ==== | |||
If you need to run php-based or other web applications on the same server, and if you can get a DNS change to point another name at the same ip address as your server, this configuration should work for you. Note: for the Rails app you must put its public folder in the Document Root, and that means you'll need two or more vhosts on your server. | |||
Lets say your old PHP apps are available at www.office.example.com, and the Rails app, myrailsapp, will be at www.rails.example.com. Edit your /etc/apache2/sites-available/default file and add this to the end of it: | |||
<pre><nowiki> | |||
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/apache2/mod_passenger.so | |||
<VirtualHost *:80> | |||
ServerAdmin [email protected] | |||
ServerName www.rails.example.com | |||
DocumentRoot /var/www/myrailsapp/public/ | |||
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.5 | |||
PassengerRuby /usr/bin/ruby1.8 | |||
<Directory "/var/www/myrailsapp/public/"> | |||
Options Indexes +ExecCGI FollowSymLinks | |||
Order allow,deny | Order allow,deny | ||
Allow from all | Allow from all | ||
</Directory> | </Directory> | ||
</VirtualHost> | |||
</nowiki></pre> | |||
* The loadmodule passenger line is required and will be given to you by the passenger setup script. Use whatever path it provides. | |||
</VirtualHost></nowiki></pre> | * You MUST change your local DNS to point www.rails.example.com to the same ip address as www.office.example.com, see your administrator or your ISP. | ||
* The PassengerRoot and PassengerRuby are also required. | |||
* As usual with Apache there are many other ways to set up vhosts, see http://httpd.apache.org/docs/2.2/vhosts/ | |||
The .htaccess file was needed by my application in the myapp/public directory ( note that it assumes a dispatch.cgi file): | |||
<pre><nowiki> | |||
Options +FollowSymLinks +ExecCGI | |||
<pre><nowiki> | RewriteRule ^(.*)$ dispatch.cgi [QSA,L] | ||
RewriteEngine On | |||
RewriteRule ^$ index.html [QSA] | |||
RewriteRule ^([^.]+)$ $1.html [QSA] | |||
RewriteCond %{REQUEST_FILENAME} !-f | |||
</nowiki></pre> | |||
==== Apache + Mongrel ==== | |||
You have to start Mongrel Cluster (under www-data ?). | |||
<pre><nowiki> | |||
sudo mongrel_rails start -d -p 8000 -e production -P /full/path/to/log/mongrel-1.pid | |||
</nowiki></pre> | |||
And configure Apache's vhost: | |||
<pre><nowiki> | |||
<VirtualHost *:80> | |||
ServerName otherserver.me | |||
ProxyPass / http://otherserver.me:8000/ | |||
ProxyPassReverse / http://otherserver.me:8000 | |||
ProxyPreserveHost on | |||
<Proxy *> | |||
Order allow,deny | |||
Allow from all | |||
</Proxy> | |||
</VirtualHost> | |||
</nowiki></pre> | |||
[http://mongrel.rubyforge.org/wiki/Apache RubyForge Mongrel - Apache Best Practice Deployment] | |||
==== Lighttpd ==== | |||
Edit lighttpd.conf, e.g.: | |||
<pre><nowiki> | |||
sudo kate /etc/lighttpd/lighttpd.conf | |||
</nowiki></pre> | |||
and here starts the tricky part, paste at the end of the file: | |||
<pre><nowiki> | |||
server.modules += ( "mod_fastcgi", "mod_rewrite" ) | |||
$HTTP["host"] == "localhost" { | |||
server.document-root = "/home/santiago/proyectos/beholder/public/" | |||
server.dir-listing = "disable" | |||
server.error-handler-404 = "/dispatch.fcgi" | |||
fastcgi.server = ( ".fcgi" => ( "localhost" => ( | |||
"min-procs" => 1, | |||
"max-procs" => 1, | |||
"socket" => "/tmp/ruby-beholder.socket", | |||
"bin-path" => "/home/santiago/proyectos/beholder/public/dispatch.fcgi", | |||
"bin-environment" => ( "RAILS_ENV" => "development" ) | |||
) ) ) | |||
} | |||
</nowiki></pre> | |||
now run | |||
<pre><nowiki> | |||
sudo /etc/init.d/lighttpd restart | |||
</nowiki></pre> | |||
and you're set, go to http://localhost and you should see the rails index... click on the link "About your rails environment" and if you don't see a 404 or 500 error... then you're set (you should see either a rails error, or a rails message or something like that). | |||
=== Known Problems === | |||
just in case you get a message like this: | |||
<pre><nowiki> | |||
kmin@metakmin:~/ruby_test$ gem -v | |||
1.2.0 | |||
kmin@metakmin:~/ruby_test$ rails -v | |||
Rails 2.2.2 | |||
kmin@metakmin:~/ruby_test$ gem update --system | |||
Updating RubyGems | |||
Nothing to update | |||
kmin@metakmin:~/ruby_test$ script/server | |||
Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update | |||
--system` and try again. | |||
kmin@metakmin:~/ruby_test$ | |||
</nowiki></pre> | </nowiki></pre> | ||
dont panic, just run: | |||
<pre><nowiki>sudo | <pre><nowiki> | ||
sudo gem install rubygems-update | |||
sudo update_rubygems | |||
</nowiki></pre> | </nowiki></pre> | ||
If you get a message like this when starting WEBrick on 9.10 | |||
<pre><nowiki> | |||
/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:271:in `require_frameworks': no such file to load -- net/https (RuntimeError) | |||
</nowiki></pre> | </nowiki></pre> | ||
You may need to install these: | |||
<pre><nowiki> | <pre><nowiki> | ||
sudo apt-get install build-essential libopenssl-ruby | |||
sudo apt-get install ruby rubygems ruby1.8-dev libsqlite3-dev | |||
</nowiki></pre> | |||
* thanks to Tomasz Przybysz who mailed me with the problem and then with the solution | |||
for any comments on the lighttpd install please feel free to mail me to santiago-ve@ubuntu.com | |||

Alternative to manual installation
Some users may prefer to skip manual installation by using the unofficial pre-integrated TurnKey Ruby on Rails Appliance based on Ubuntu LTS.
Intro Ubuntu 8.04
These instructions are for Ubuntu 8.04 LTS (hardy). Instead of using apt
we use gems because of what ReinH put best...
<ReinH> Let gems manage your rails package otherwise gem and apt-get will start fighting like Spock and Captain Kirk in Amok Time. If you haven't seen that episode, trust me: you don't want that.
Intro Ubuntu 9.04 ... Apache2.2 tested only
Slight additions from 8.04 documentation...
- Using Passenger ( mod_rails ) may be required, it was for me. see http://www.modrails.com/documentation/Users%20guide.html Do NOT try a manual installation, use gems only.
- Do the minimum Ruby installation from Debian packages ( apt-get | Aptitude | Synaptic ). First install Ruby and Apache and rubygems as described below using Debian packages, then use gems only for the other Ruby-based applications.
- Use an Apache vhost configuration that puts the myapp/public directory at the document root. see http://httpd.apache.org/docs/2.2/vhosts/name-based.html
- Using an .htaccess file in the myapp/public directory may be required.
- Using fastcgi or fcgid Apache modules is not required, and may not work at all.
- The Rails group is another good place to ask for assistance... http://groups.google.com/group/rubyonrails-talk
- The Rails guide is excellent... http://guides.rubyonrails.org/index.html
Get Ruby
sudo apt-get install ruby-full build-essential
Note that `ruby-full` will install emacs and a slew of other non-essential packages. You can install all the necessary packages with this command:
sudo aptitude install ruby build-essential libopenssl-ruby ruby1.8-dev
Server Installation
Now you have ruby, you already got a server included, WEBrick. You may settle with that, also because the installation is much easier, and reboots are faster. But it lacks the configuration options that apache and lighttpd offer. So if you want to have RubyOnRails running on apache or lighttpd, make sure you have installed these first.
Apache
sudo apt-get install apache2 apache2-mpm-prefork apache2-prefork-dev
WARNING: libapache2-mod-passenger installation uninstalls libapache2-mod-php5 and php5.
Apache + Mongrel
Mongrel Cluster works as a proxy service under Apache (no additional modification is required).
sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod rewrite sudo /etc/init.d/apache2 restart sudo apt-get install mongrel
Rails Wiki - Apache + Mongrel RubyForge Mongrel - Apache Best Practice Deployment
Lighttpd
Preparing the house:
sudo apt-get install lighttpd libfcgi-ruby1.8
Installing RubyGems
The link below is to a specific version of RubyGems (version 1.1). You can get a later version from http://rubyforge.org/frs/?group_id=126, but it should not be really necessary because we ask RubyGems to update itself at the end. But to make it more complete, a description of RubyGems 1.2 is also included, below the install instructions of RubyGems 1.2.
RubyGems via apt
sudo apt-get install rubygems
As of July 27, 2009, RubyGems 1.3.1 is installed via apt. To make gem work properly you should write gem's path to PATH add to ~/.bashrc:
export PATH=/var/lib/gems/1.8/bin:$PATH
To export path once just enter previous code to bash.
RubyGems 1.1.0
wget http://rubyforge.org/frs/download.php/34638/rubygems-1.1.0.tgz tar xzvf rubygems-1.1.0.tgz cd rubygems-1.1.0 sudo ruby setup.rb sudo ln -s /usr/bin/gem1.8 /usr/bin/gem sudo gem update --system
RubyGems 1.2.0
wget http://rubyforge.org/frs/download.php/38646/rubygems-1.2.0.tgz tar xzvf rubygems-1.2.0.tgz cd rubygems-1.2.0 sudo ruby setup.rb sudo ln -s /usr/bin/gem1.8 /usr/bin/gem sudo gem update --system
The below error is sometimes encountered after running sudo gem update --system.
/usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)
To fix that error follow the below instructions.
sudo gedit /usr/bin/gem In the file find: require 'rubygems' Add the following line below the above line: require 'rubygems/gem_runner'
RubyGems 1.3.1 Ubuntu 8.04
wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz tar xzvf rubygems-1.3.1.tgz cd rubygems-1.3.1 sudo ruby setup.rb sudo ln -s /usr/bin/gem1.8 /usr/bin/gem sudo gem update --system
RubyGems 1.3.1 Ubuntu 9.04
sudo apt-get install rubygems1.8 sudo gem install rubygems-update sudo update_rubygems note: this will clean out your gems!
Installing rails
We can now use RubyGems to install rails:
sudo gem install rails
Also we can install rails from apt ( not suggested for Ubuntu 9.04 )
sudo apt-get install rails
I think, it would be better to install rails with gem. If you encounter difficulties installing fcgi (fastcgi) via gem, this might help:
sudo aptitude install libfcgi-dev
Preparing for your first rails app
Configuration of the webserver also assumes you have by then a rails application set up. Simply enter to get that done (it will create you a first test page): Default (sqlite3 backend):
rails /home/myuser/www/mynewapp
For a mysql back-end. Run this one, if you installed rails with gem:
rails /home/myuser/www/mynewapp -d mysql
Run this one, if you installed rails with apt:
rails /home/myuser/www/mynewapp -D mysql
You will see a bunch of stuff on the shell... that should be fine (unless you see a error message). That created the rails folder with all the stuff, so now you should have something like have: /home/myuser/www/mynewapp/public
Configure the server
WEBrick (Ruby's server)
No configuring needed, everything is ready to create your first application. You can even try this step before you try launching your application via apache or lighttpd:
$cd /home/myuser/www/mynewapp $ruby script/server => Booting WEBrick... => Rails 2.1.0 application started on http://0.0.0.0:3000 => Ctrl-C to shutdown server; call with --help for options [2008-07-28 04:39:17] INFO WEBrick 1.3.1 [2008-07-28 04:39:17] INFO ruby 1.8.6 (2007-09-24) [2008-07-28 04:39:17] INFO WEBrick::HTTPServer#start: pid=6860 port=3000
Your application is now responding at `http://0.0.0.0:3000`; press Ctrl+C to stop the web server. If you get errors related to the database, you might need to install a DB connector, or create a database. Edit this in `$YOUR_RAILS_DIRECTORY/config/database.yml` Install the sqlite3 connector:
sudo apt-get install libsqlite3-dev sudo gem install sqlite3-ruby
Or install the MySQL database and it's connector:
sudo apt-get install mysql-server mysql-client sudo apt-get install libmysql-ruby libmysqlclient-dev sudo gem install mysql
Or install the PostgreSQL database and it's connector:
sudo apt-get install postgresql-server postgresql-client sudo apt-get install libpq-dev sudo gem install pg
Apache
Run the following to install passenger, an apache module that adds support for running rails apps within apache:
sudo gem install passenger sudo apt-get install apache2-dev libapr1-dev libaprutil1-dev sudo passenger-install-apache2-module
WARNING: libapache2-mod-passenger installation uninstalls libapache2-mod-php5 and php5.
Now you have to configure apache to point to the passenger module. Simply copy the following suggested code from the passenger-install-apache2-module
installation to the end of your Apache configuration file, which can be accessed by typing in the command sudo gedit /etc/apache2/apache2.conf
:
(if you are using RubyGems 1.1):
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-1.0.3/ext/apache2/mod_passenger.so RailsSpawnServer /usr/lib/ruby/gems/1.8/gems/passenger-1.0.3/bin/passenger-spawn-server RailsRuby /usr/bin/ruby1.8
(if you are using RubyGems 1.2):
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3 PassengerRuby /usr/bin/ruby1.8
(if you are using RubyGems 1.3.1):
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.6/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.6 PassengerRuby /usr/bin/ruby1.8
(if you are using RubyGems 1.3.6 and Ubuntu 9.10):
LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.11 PassengerRuby /usr/local/bin/ruby
Now you should point apache to the location of your Ruby app. Create something like this in /etc/apache2/sites-available/ror.myhost.com
<VirtualHost *> ServerName ror.myhost.com DocumentRoot /home/myuser/www/mynewapp/public RailsEnv development #It's optional string, but my rails app didn't work properly without it. </VirtualHost>
Alternatively, you could run rails in a specific sub uri of your current host, e.g. localhost. First, make a symbolic link to your rails public folder from with var/www (or wherever you have the root of your apache www folder), e.g.:
ln -s /home/myuser/www/mynewapp/public /var/www/mynewapp
In case of localhost (which is the default host with a fresh ubuntu/apache install) edit default
in /etc/apache2/sites-available
and add:
RailsBaseURI /mynewapp
murb: I had to add RailsEnv development
as well to get around the 'no route found to match "/rails/info/properties" with {:method=>:get}' warning... (can someone elaborate on why?) apparently this is because /info/properties is buggy and no longer supported: http://www.ruby-forum.com/topic/161924
Save, and enable the rewrite module for apache, and register this site... and finally, restart apache.
sudo a2enmod rewrite sudo a2ensite ror.myhost.com sudo /etc/init.d/apache2 restart
An Alternate Apache Configuration with a named vhost Ubuntu 9.04
If you need to run php-based or other web applications on the same server, and if you can get a DNS change to point another name at the same ip address as your server, this configuration should work for you. Note: for the Rails app you must put its public folder in the Document Root, and that means you'll need two or more vhosts on your server. Lets say your old PHP apps are available at www.office.example.com, and the Rails app, myrailsapp, will be at www.rails.example.com. Edit your /etc/apache2/sites-available/default file and add this to the end of it:
LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/apache2/mod_passenger.so <VirtualHost *:80> ServerAdmin [email protected] ServerName www.rails.example.com DocumentRoot /var/www/myrailsapp/public/ PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.5 PassengerRuby /usr/bin/ruby1.8 <Directory "/var/www/myrailsapp/public/"> Options Indexes +ExecCGI FollowSymLinks Order allow,deny Allow from all </Directory> </VirtualHost>
- The loadmodule passenger line is required and will be given to you by the passenger setup script. Use whatever path it provides.
- You MUST change your local DNS to point www.rails.example.com to the same ip address as www.office.example.com, see your administrator or your ISP.
- The PassengerRoot and PassengerRuby are also required.
- As usual with Apache there are many other ways to set up vhosts, see http://httpd.apache.org/docs/2.2/vhosts/
The .htaccess file was needed by my application in the myapp/public directory ( note that it assumes a dispatch.cgi file):
Options +FollowSymLinks +ExecCGI RewriteRule ^(.*)$ dispatch.cgi [QSA,L] RewriteEngine On RewriteRule ^$ index.html [QSA] RewriteRule ^([^.]+)$ $1.html [QSA] RewriteCond %{REQUEST_FILENAME} !-f
Apache + Mongrel
You have to start Mongrel Cluster (under www-data ?).
sudo mongrel_rails start -d -p 8000 -e production -P /full/path/to/log/mongrel-1.pid
And configure Apache's vhost:
<VirtualHost *:80> ServerName otherserver.me ProxyPass / http://otherserver.me:8000/ ProxyPassReverse / http://otherserver.me:8000 ProxyPreserveHost on <Proxy *> Order allow,deny Allow from all </Proxy> </VirtualHost>

Lighttpd
Edit lighttpd.conf, e.g.:
sudo kate /etc/lighttpd/lighttpd.conf
and here starts the tricky part, paste at the end of the file:
server.modules += ( "mod_fastcgi", "mod_rewrite" ) $HTTP["host"] == "localhost" { server.document-root = "/home/santiago/proyectos/beholder/public/" server.dir-listing = "disable" server.error-handler-404 = "/dispatch.fcgi" fastcgi.server = ( ".fcgi" => ( "localhost" => ( "min-procs" => 1, "max-procs" => 1, "socket" => "/tmp/ruby-beholder.socket", "bin-path" => "/home/santiago/proyectos/beholder/public/dispatch.fcgi", "bin-environment" => ( "RAILS_ENV" => "development" ) ) ) ) }
now run
sudo /etc/init.d/lighttpd restart
and you're set, go to http://localhost and you should see the rails index... click on the link "About your rails environment" and if you don't see a 404 or 500 error... then you're set (you should see either a rails error, or a rails message or something like that).
Known Problems
just in case you get a message like this:
kmin@metakmin:~/ruby_test$ gem -v 1.2.0 kmin@metakmin:~/ruby_test$ rails -v Rails 2.2.2 kmin@metakmin:~/ruby_test$ gem update --system Updating RubyGems Nothing to update kmin@metakmin:~/ruby_test$ script/server Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again. kmin@metakmin:~/ruby_test$
dont panic, just run:
sudo gem install rubygems-update sudo update_rubygems
If you get a message like this when starting WEBrick on 9.10
/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:271:in `require_frameworks': no such file to load -- net/https (RuntimeError)
You may need to install these:
sudo apt-get install build-essential libopenssl-ruby sudo apt-get install ruby rubygems ruby1.8-dev libsqlite3-dev
- thanks to Tomasz Przybysz who mailed me with the problem and then with the solution
for any comments on the lighttpd install please feel free to mail me to [email protected]
