Answer 1

This is a good reference. And I got if fixed through this http://www.ultrasaurus.com/sarahblog/2008/12/getting-started-with-rails-2-day-1/

Answer 2

Re-install mysql-server and mysql-client using this command:

sudo apt-get install mysql-server mysql-client

and then some libraries you need to install to make MySQL available to ruby:

sudo apt-get install libmysql-ruby

This all solved my problem. Try it !!! :)

Answer 3

I was having the same problem than you, me and my friends were all going mad because of it, until we've found this link http://weblog.rubyonrails.org/2009/8/30/upgrading-to-snow-leopard

I've just followed the mysql installation steps and it worked great here :]

Answer 4

I just encountered this as well on a fresh Snow Leopard install.

I had another project that created the databases without issue, but my primary project would give the errors you described. After poking around, the only difference was the former specified a socket, whereas the failing project (and yours too) uses a host.

That is to say, this database.yml causes the problem:

development:
  adapter: mysql
  database: fanvsfan_development
  username: root
  password:
  host: localhost

But this works:

development:
  adapter: mysql
  database: fanvsfan_development
  username: root
  password:
  socket: /tmp/mysql.sock

I'm unsure what the actual difference is, but this seems like a workaround.

Answer 5

Does the database already exist? Is MySQL setup and running? What changed? (OS Upgrade maybe)? Does a fresh rails app work? What about your other environments (test, production)?

Is there a back trace? you could post (use rake --trace db:create). Usually MySQL is returns a very explicit error message, rake is just eating it.

Answer 6

Using RVM? Do this for Rails v 2.3

export ARCHFLAGS="-arch x86_64" ; gem install --no-rdoc --no-ri mysql -v 2.7 -- --with-mysql-dir=/usr/local --with-mysql-config=/usr/local/mysql/bin/mysql_config
