【问题讨论】：

你可以从 shell 登录 mysql（不使用 Rails）吗？

【参考方案1】：

我在你的堆栈跟踪中没有看到 mysql gem，所以我怀疑你可能没有安装它。如果是这样，请将gem 'mysql'（或gem 'mysql2'，如果您愿意）添加到您的Gemfile，运行bundle install 并再次启动您的服务器。

此外，请仔细检查您是否确实在运行问题中提到的 Rails 3。堆栈跟踪显示您正在运行 Rails 2.3。同样，在您的 Gemfile 中，确保您有 gem 'rails', '3.0.0'，然后运行 ​​bundle install，等等。

【讨论】：

感谢您指出 rails 版本。它是 2.3.5 但错误地是 3.0.0

我怀疑是这样。我最近安装了 Rails 2.3.5，它在安装说明中明确指出该版本的 Rails 中不包含 mysql gem，因此您必须gem install mysql 才能使 MySQL 正常工作。

您还应该确保您实际启动了 MYSql 服务器。
