I have XAMPP installed on Ubuntu 12.04 and it all works.
I've also been using Rails for a while with PostgreSQL and it also worked fine.
Today, I tried creating a new app using mysql with mysql2 gem, and got an error while running rake db:create.
I first checked the other Rails/MySQL questions on SO, and will say:
MySQL is running
Using mysql2 gem
DB config looks correct (to me)
database.yml using socket: /opt/lampp/var/mysql/mysql.sock

You can try installing SSL libs using:
apt-get install libssl-dev
You can check the path that it has been installed in using:
apt-file list libssl-dev
you may need to install apt-file first by running:
sudo apt-get install apt-file
apt-file update

How to solve this problem?
I would rather avoid changing server-side versions.
The answers at I can't run "bundle update" because of "mysql2" gem do not solve the problem.
Local versions:
gem 2.4.8
Rails 3.0.19
mysql Ver 14.14 Distrib 5.6.25
Running these commands solved the problem:
gem uninstall mysql2
bundle install
I ran into the same problem and the accepted answer didn't work for me, most likely because I used capistrano, which installs all gems into a per-app shared directory.
bundle show mysql2
(run in your app's folder) will show you where mysql is installed. Then delete that as well as the the specification.
rm -rf /path/to/application/shared/bundle/ruby/<version>/gems/mysql2-<version>
rm /path/to/application/shared/bundle/ruby/<version>/specifications/mysql2-<version>.gemspec
should do the trick. Alternatively just delete the complete bundle/* and reinstall everything.
I am trying to use my WAMP MySQL for a Ruby on Rails installation on my Windows 7 system. I am getting errors (see below) when I try to start the rails WEBrick server.
I've installed the complete Ruby on Rails environment successfully, including the mysql2 gem. When installing the mysql2 gem, I referenced the location of the lib and includes folders of the WAMP mysql and it successfully installed:
C:\wamp\www\simple_cms>gem install mysql2 --no-document -- '--with-mysql-lib="C:\wamp\bin\mysql\mysql5.5.24\lib\" --with-mysql-include="C:\wamp\bin\mysql\mysql5.5.24\include\"
======================================================================================================
\ You've installed the binary version of mysql2.
It was built using MySQL Connector/C version 6.1.5.
It's recommended to use the exact same version to avoid potential issues.
At the time of building this gem, the necessary DLL files were retrieved from:
http://cdn.mysql.com/Downloads/Connector-C/mysql-connector-c-6.1.5-winx64.zip
\ This gem *includes* vendor/libmysql.dll with redistribution notice in vendor/README.

I'm not sure what I am doing wrong here. Any help would be appreciated.
I'm running Rails 4.0.3 on Ruby 2.0.0 on Windows 7, and have installed the DevKit (all x64).
I've installed the mysql2 gem using subst X: "C:\Program Files\MySQL\MySQL Server 5.6" and then gem install mysql2 --platform=ruby -- --with-mysql-dir=X:, and it installed fine. I then created a new app with rails new mysql_testy which ran fine, but when I run rails server I get the following error:

Do you guys have any idea what's happening?
Not sure if you figured it out yet, but I was having the same issue. I installed the 32 bit sql connector, copied the libmysql.dll file from it and pasted it into Ruby/bin folder. Opened a new command prompt and was able to connect to the server.
Before this step though you may have to reinstall a fresh MySQL2 gem pointing to the path of the connector: gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector\mysql-connector-c-6.1.5-win32\lib" --with-mysql-include="C:\mysql-connector\mysql-connector-c-6.1.5-win32\include" --with-mysql-dir="C:\mysql-connector"'
Hope this helps
I've been tinkering with this one for several days and I still get the same error. For starters, I have been able to start a newly rails app with sqlite as the database but the application we are working on uses Mysql. So when I go to the app directory and type "rails server" it gives me the following:

So (I think) MySQL development headers aren't installed, which I googled everywhere how to install them and tried most install command line to no success yet. Examples of commands I've tried:
gem install mysql2
sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include
I did the bundle install, bundle update and bundle commands in the app directory...I'm running out of options...can you help me?
I'm on mac osx 10.7
have you tried something like this, I'm one Mac OS X (lion) too and I have no problem with the mysql gem. Or may be you can find what you want here
[EDIT]
Or you can simply use ruby-mysql gem for development environment
Final edit: I played with a few different files got some more errors and then reinstalled rvm and everything else from the start, found a few fixes and edited them and finally everything works. thank you everyone for your help
Edit: I have noticed that it says Library not loaded: /usr/local/mysql-5.5.10-osx10.6-x86_64/lib/libmysqlclient.18.dylib (LoadError)
But I have mysql 5.5.11, how do I fix that?
I literally have searched for the past 3 hours, but found nothing that worked
Same error occurs when I either try to launch the server or generate a model
I have bundler and mysql2 gems.

Whenever you get load errors you should make sure you have all of the dependencies installed and in place.
Make sure you have gem mysql2 in your Gemfile.
Install bundler if you don't already have it with gem install bundler.
