Webrick Rails server won't start?

Question

I'm using Rails 4.0.0, and successfully installed the mysql2 gem yesterday (mysql-0.3.15) using mysql-connector-c-6.1.3.winx64. I created a new Rails project called "simple_cms" using rails new simple_cms -d mysql which worked, and then ran bundle install which was also fine.

When I try to run rails server I get the following errors:

C:\Users\Hans>cd sites

C:\Users\Hans\Sites>cd simple_cms

C:\Users\Hans\Sites\simple_cms>rails server

What can I do about this? By the way, the module it cannot find is in fact there.

28-Mar-2014 After all the problems I had installing and re-installing, I still could not get rails server to run. As I mainly want this installation to learn Ruby on Rails, I have instead installed the Bitnami Ruby stack, which installs everything automatically. This seems to work fine, and I've got Ruby, MySQL and the Apache Web Server working.

have you made sure that your database is installed properly ? ..you can check with `rails db` to check it connecting to database mysql properly. — userRandom, Mar 18 '14 at 18:25
with rails db I get: C:\Users\Hans\Sites\simple_cms>rails dbconsole ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) C:\Users\Hans\Sites\simple_cms> — user3424071, Mar 18 '14 at 21:33
I am going to first un-install everything and start from scratch. Maybe this weekend. Thanks for your help Eugene and Rahul. — user3424071, Mar 19 '14 at 04:48

I had similar problems configuring the Lynda course on learning Ruby on Rails. I found an additional step that seemed to work for me. Since the error was complaining about the lack of a database in mysql, I created the missing database and that fixed the problem.

Log into mysql as root and prompt for password:

mysql -u root -p

Then:

SHOW DATABASES;

CREATE DATABASE simple_cms_development; 

exit;
