MySQL DB的Rails项目连接错误-拒绝root用户访问

Question

I get this error when running rails with mysql db. Basically it is not giving the root user access. I have no idea why this is and have been stuck with this for a while now.

Mysql2::Error (Access denied for user 'root'@'localhost' (using password: YES)):
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack- 3.1.0/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.3ms)
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.1.0/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (5.7ms)
Rendered /Users/USER/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.1.0/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (17.7ms)

My Database.yml file is posted below for your reference. Im not sure how i check the password that MYSQL is automatically assigned to? Would it be my computer login password? Anyhow how do i check it. Also i cant simply type mysql on my command line i have to enter the entire path to access it. How do i change it. Most importantly i want to know how this access denied issue can be resolved. Thank you. Using mysql 5.5 on mac. x86_64 build.

Mysql uses the one that you've set on install. Sometimes it's empty. Try mysql -u root. If it works - remove pass string form database yaml. If it's not empty - https://stackoverflow.com/search?q=mysql+reset+password
