Install thinking Sphinx in Ubuntu 13.04 and set up in Rails 3.2

Check sphinx is already installed in your system,

$ search 

If you have already sphinx installed then it will show the sphinx version and other info, else it shows ubuntu information to install.

Download thinking sphinx from
here,

$ tar -xzf sphinx-2.0.8-release.tar.gz
$ cd sphinx-2.0.8-release/
$ ./configure
$ make
$ sudo make install

Type,

$ search 

it will show the sphinx release and the other information.
Add the sphinx gem into your Gemfile

gem 'thinking-sphinx'

Do bundle install

$ bundle install

I assume you already made the model / controller code for sphinx. Else see this
Index all your records

$ rake ts:index -t

While indexing sphinx will generate the configuration file inside RAILS_ROOT/config/config/development.sphinx.conf

If you need to generate only configuration file not indexing you can use this command

$ rake ts:configure -t

Run sphinx searchd daemon

$ rake ts:start -t

You can stop sphinx searchd daemon

$ rake ts:stop -t

You can reindex so that sphinx will re index all records without creating a configuration file.

$ rake ts:reindex -t

Enjoy Sphinx searching!
