我一直在尝试通过Phusion Passenger使用Ruby on Rails和mySQL来设置Apache服务器。我有Apache v2.2.3,Passenger v3.0.13,Ruby v1.9.3,Rails v3.2.6和mySQL v5.0.95。Rails无法连接到mySQL
此前,由于Javascript运行时不正确,我遇到了问题,但我可以通过安装execjs和therubyracer来解决此问题。我成功地使用SQLite创建网站,但我需要使用mySQL。
现在,我用命令“rails new myProject -d mysql”创建了一个新项目,并将相应的gem添加到我的Gemfile中(也就是“gem'mysql2','0.3.11'”;“gem 'execjs'“和”gem'therubyracer'“)。
我的database.yml文件看起来像这样(的测试和生产的部分只在名称上有所不同):
development:
adapter: mysql2
encoding: utf8
database: myProject_development
pool: 5
username: root
password:
host: localhost
socket: /var/lib/mysql/mysql.sock
现在的问题是不会立即显现。从终端,我找不到任何问题(即“耙分贝:创建”运行正常,没有出现任何错误在脚手架等),但是当我浏览网页,乘客显示以下错误:
红宝石(机架)应用程序无法启动
找不到任何的来源(捆扎机:: GemNotFound)
mysql2-0.3.11并没有网页的出现。那么,我的错在哪里?我相信我的Gemfile是正确的,我的database.yml似乎更新了,我可以从终端访问mySQL,并且我能够在SQLite中运行网站。任何建议,将不胜感激!
编辑:我的Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.6'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'mysql2','0.3.11'
# Gems used only for assets and not required
# in production environments by default.
group :assets do

您是否在添加mysql2 gem后运行'bundle'? – deefour 2012-07-10 22:38:06
