How do I configure PostgreSQL or MySQL to set up a database with Sphinx?

问题

I really need help installing Sphinx and getting it going.

I'm on rails 3 and I'm following these set of directions: http://freelancing-god.github.com/ts/en/quickstart.html to install Sphinx.

Thinking Sphinx was easy to install since it's a gem. However, the guide says I need to have both Sphinx and Thinking Sphinx installed to get started (Is this true?). I checked Ryan Bates' railscast for Thinking Sphinx and he only installed the plugin and got started immediately.

Anyways, I installed Sphinx via MacPorts and here's proof:

...
  --->  Configuring mysql5
  --->  Building mysql5
  --->  Staging mysql5 into destroot
  --->  Installing mysql5 @5.1.57_0
   The MySQL client has been installed.

...

--->  Installing sphinx @0.9.9_0+mysql5
--->  Activating sphinx @0.9.9_0+mysql5
--->  Cleaning sphinx

It automatically configured Sphinx with mysql5. I have both mySQL and POSTgreSQL.

Now the next step was to rake thinking_sphinx:index after setting up an index in my user model which looks like this:

  define_index do
   indexes year
   indexes major
   indexes books_buy
   indexes books_sell
   indexes facebook
   indexes restaurants
   indexes interests

   end

However, rake thinking_sphinx:index gave me this:

rake aborted!
Don't know how to build task 'thinking_sphnix:index'

and then

rake aborted!
no such file to load -- sqlite3

So I figured my database was configured on sqlite3 still. So I switched the gem to mySQL and edited my database.yml file to look like this:

# Switched over to mysql

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
development:
  adapter: mysql5
  encoding: utf8
  database: sphinx_development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

test:
  adapter: mysql5
  encoding: utf8
  database: sphinx_test
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

production:
  adapter: mysql5
  encoding: utf8
  database: sphinx_production
  pool: 5
  username: root
  password: 
  socket: /tmp/mysql.sock

and I got these errors:

rake aborted!
Please install the mysql5 adapter: `gem install activerecord-mysql5-adapter` (no such file to load -- active_record/connection_adapters/mysql5_adapter)

and

    ERROR:  Could not find a valid gem 'activerecord-mysql5-adapter' (>= 0) in any repository
ERROR:  Possible alternatives: activerecord-jdbcmysql-adapter, activerecord-nulldb-adapter, activerecord-odbc-adapter, activerecord-jdbc-adapter, activerecord-postgis-adapter
Tony-Ngs-MacBook-Air:sample_app TonyNg$ gem install activerecord-nulldb-adapter

Any tips would be generous and helpful. Would also be willing to switch to PostgreSQL if help lead provided. Thanks!

You need to put either mysql or mysql2 as your adapter - and include either gem (same names as the adapters) in your Gemfile. I recommend mysql2, as it's actively maintained - but keep in mind if you're using Rails 3.0.x, then you must use a 0.2.x release of mysql2. If you're on Rails 3.1, then use mysql2 0.3.x.
