I am having an issue connecting to the mysql database using rails. I'm a newbie to rails but I have tried the guide here:
rails + MySQL on OSX: Library not loaded: libmysqlclient.18.dylib
and this still does not work. I believe I have two installations of mysql installed and this is confusing rails.
I have MAMP installed with it's own mysql and I also have the rails mysql2 gem installed. When I follow the steps from the link provided above, I think this is using the MAMP mysql install instead of the mysql2 install that I have with rails gems so it isn't recognizing it.
Is there any way I can consolidate the two mysql's into one? Or is it easier to modify rails so it can see the mysql2 gem?
Here is my error:

#markmilly Answer to your last comment:
'rake db:create' creates the db that you specified in your config/database.yml file.
It will create the db for the current RAILS_ENV you're on. If the environment is not specified it will default to the development and test db's.
I see this answer is a bit late, but it might help someone else.

It is possible that all dependencies are not installed. If you have not used rvm to install ruby, you should try using it to install your ruby version.
rvm install 1.9.3
or
rvm reinstall 1.9.3
refer https://rvm.io/rvm/install for step by step instructions.
This is me trying to use MySql on rails for the first time. This happens with using sqlite3 as well except it points to me do 'gem install activerecord-sqlite3-adapter`,the tells me there is no such gem named it.
I am using the lastest Ruby 2.0.
I am using the lastest Rails 3.2.13
I have the mysql2 (0.3.11) gem
I also have the activerecord-mysql2-adapter (0.0.3)
Yet... it is giving me the following message:
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/rubygems_integration.rb:214:in 'block in replace_gem': Please install the mysql2 adapter: 'gem install activerecord-mysql2-adapter' (mysql2 is not part of the bundle. Add it to Gemfile.) (LoadError)
The bundler ran when I executed rails new [project name]
If it was mysql2 gem's error, this command successfully installs mysql2 on 64 bit Windows systems:gem install mysql2 -v '0.3.11' -- '--with-mysql-lib="C:\MySQL\lib" --with-mysql-include="C:\MySQL\include"'
Gemfile generated is using gem 'mysql2'ok, normal as I have been told.
Database.yml is as follows:
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: shop_development
pool: 5
username: charlie
password: *******
host: localhost
And I have manually created a database called [projectname]_development.

Check for following things
Does your Gemfile have the entry saying gem 'mysql2' ?
What happens when you run $ bundle update command? any errors
Can you try the following command to generate your app,
rails new demo_app -d mysql
What error you get when you try the above app?
I want to continue programming a rail app but the following error occurs when I try to start the server rails s.
My rail installation seems to work fine when I have a brand new directory (it uses sqlite3 there). I also probably have everything installed, xcode, homebrew, RVM...
Operating system: OS X, 1.8.2
Any ideas to solve this error?

The location is different on osx, look for /private/var/mysql/mysql.sock
Your options are to change the socket value in database.yml or create a symbolic link at /tmp/myslq.sock
I prefer the later since it's a common issue.
I installed the ruby-mysql gem using bundler. But Mysql.connect is crashing with the following trace.

My machine is running Ubuntu 12.04 and i have libmysqlclient-dev already installed. How can i fix this problem ?
Thank You
I believe that you should just change socket in your database.yml.
Try changing it from
/tmp/mysql.sock
to
/var/run/mysqld/mysqld.sock
I followed the instruction and installed the sunspot_rails gem
when I do
bundle exec rake sunspot:solr:start
it tells me
This command is not supported on i386-mingw32. Use rake sunspot:solr:run to run Solr in the foreground.
when I use that command I get
** Invoke sunspot:solr:run (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:solr:run
The syntax of the command is incorrect.
rake aborted!
You need a Java Runtime Environment to run the Solr server

Tasks: TOP => sunspot:solr:run
I am running windows 7 x64.
sunspot won't run on windows?
solved..
Thought it was a java issue, but even after I installed java it won't work.
I found the answer (which apparently shouldn't be an issue with latest push of sunspot..)
the latest push fixed the issue
https://github.com/sunspot/sunspot/commit/721d3419492852533764d58f2c7f398687891a94
since bundler apparently didn't fetch me the latest, I changed it manually and it now works..
