Question

我要用ruby on rails连接Mysql，可是总是不行

我在网上看了大量资料，什么libmysql.dll,ruby.mysql的驱动都装好了，而且单用ruby项目也就是拿一个ruby文件来连mysql却是相当成功！！
当我创建一个新项目时（我用的是RadRails IDE），选中连接mysql并出现欢迎界面后，点击About your application’s environment时本应出现我的项目的相关信息，可结果总是出现：We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.

但每次创建新项目时数据库选则sqlite就没问题，我mysql已经安好了啊，这rails到底如何才能连上mysql啊，都折腾一周了，急！

Answer 1

首先检查一下你的mysql服务打开没有
你再检查一下/config/database.yml
项目默认的好像是链接sqlite3
默认值
# SQLite version 3.x
# gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
adapter: sqlite3
database: db/development.sqlite3
timeout: 5000

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
test:
adapter: sqlite3
database: db/test.sqlite3
timeout: 5000

production:
adapter: sqlite3
database: db/production.sqlite3
timeout: 5000
-----------------------

mysql应该的是
# SQLite version 3.x
# gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
adapter: mysql
database: 项目的数据库名
username: root
password: 你的密码
socket: /path/to/your/mysql.sock

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
test:
adapter: mysql
database: 项目的数据库名
username: root
password: 你的密码
socket: /path/to/your/mysql.sock

production:
adapter: mysql
database: 项目的数据库名
username: root
password: 你的密码
socket: /path/to/your/mysql.sock

Rails工程下config目录中的环境配置文件里的数据库连接部分是否配置正确？
