Setting up Ruby on Rails Database Connection using SQLite (version 2 and 3) on Fedora 7

aizatto — Sun, 10 Jun 2007 14:25:20 +0000

SQLite is good for development and testing, and depending on your needs production even. By default Typo uses SQLite for production. The greatest advantage is that it's light. (like duh), and very easy to deploy.

Note: There are two versions of SQLite, version 2 and 3. They produce databases which are incompatible with each other.

Version 2

Enter into the Terminal, and as root execute:



yum install gcc ruby-devel sqlite2-devel

gem install sqlite-ruby

If you see this, you want the ruby version, so select 1 (enter it in).



Select which gem to install for your platform (i486-linux)

 1. sqlite-ruby 2.2.3 (ruby)

 2. sqlite-ruby 2.2.3 (mswin32)

 3. sqlite-ruby 2.2.2 (ruby)

 4. sqlite-ruby 2.2.2 (mswin32)

 5. Skip this gem

 6. Cancel installation

>

Edit the file RAILS_ROOT/config/database.yml. For now we are using the development environment. The environment you are deploying your database should look like so.

development:
  adapter: sqlite
  dbfile: db/development.sql

Version 3

Enter into the Terminal, and as root execute:



yum install gcc ruby-devel sqlite-devel

gem install sqlite3-ruby

If you see this, you want the ruby version, so select 2 (enter it in).



Select which gem to install for your platform (i486-linux)

 1. sqlite3-ruby 1.2.1 (mswin32)

 2. sqlite3-ruby 1.2.1 (ruby)

 3. sqlite3-ruby 1.2.0 (mswin32)

 4. sqlite3-ruby 1.2.0 (ruby)

 5. Skip this gem

 6. Cancel installation

>

Edit the file RAILS_ROOT/config/database.yml. For now we are using the development environment. The environment you are deploying your database should look like so.

development:
  adapter: sqlite3
  dbfile: db/development.sql

Conclusion

There you have it, your database is now set up!

Installing Ruby on Rails on Fedora 7

aizatto — Sun, 10 Jun 2007 14:25:05 +0000

Note:

I recommend installing Ruby on Rails via RubyGems
As long as you have Ruby installed, you can install Ruby on Rails, just skip the step about installing Ruby.
I have instructions if you are interested in Installing Ruby On Rails on Ubuntu.

Plan of Attack

This is a quick down and dirty guide to getting Ruby and Rails working in Fedora 7. You may notice this is installed into /tmp , I do this because its universal on all Fedora and Linux distributions.

Install Ruby
Install RubyGems via source
Install Ruby on Rails using RubyGems
Test Rails installation

Warning:

Certain commands need to be executed as root. Lines requiring to be run as root, begin with a hash (#). To enter root execute su - .
If a line begins with a dollar sign ($), those can be run as a normal user.
If a line begins with a hash or a dollar sign, do not enter the starting hash or dollar sign into the terminal

Install Ruby

su -
yum install ruby ruby-rdoc ruby-irb

Note: If you get an error, similar to the following, just wait a while and try the above command again.

Loading "installonlyn" plugin

Existing lock /var/run/yum.pid: another copy is running as pid 2321. Aborting.

Note: If you get something similar to the following, just enter y.

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2

Importing GPG key 0x4F2A6FD2 "Fedora Project " from /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

Is this ok [y/N]:

Install RubyGems via source

Note: Latest version of RubyGems (0.9.4) as of 10th June 2007.
Enter into the Terminal:

cd /tmp
wget http://rubyforge.org/frs/download.php/20989/rubygems-0.9.4.tgz
tar -zxvf rubygems-0.9.4.tgz
cd rubygems-0.9.4
ruby setup.rb

Install Ruby on Rails using RubyGems

Enter into the Terminal:

gem install -y rails

Note: If it fails, try executing gem update and then execute the command above again.

Test Rails installation

Enter into the Terminal:

rails /tmp/railstest
cd /tmp/railstest
./script/server

Open up Firefox and go to http://localhost:3000, a page should show up indicating a successful installation. Your basically good to go with the minor exception of a database connection.

After...

Generally you'd want some sort of database connection, with the three standards choices being.

SQLite:
If you just want to experiment with Ruby on Rails, I'd recommend using SQLite.
MySQL
PostgreSQL

Stay tuned!
