贴 config/database.yml

#1楼 @Rei development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 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 pool: 5 timeout: 5000

production: adapter: postgresql database: production pool: 5 timeout: 5000 [user@localhost config]$

heroku 不支持 sqlite 数据库。

#3楼 @Rei 只是测试和开发模式下是sqlite啊,porduction模式下是postgresql

#4楼 @shangchen 目测还要加连接参数,但是我没搜到文档,自己也没用过,所以不知道了。

#4楼 @shangchen heroku似乎会自动生成production环境的数据库配置,你把database.yml里的production数据库配置删了试试。- -。

@shangchen 你直接将database.yml从git的版本库剔除就好了,不要push到heroku上面去。

#9楼 @shangchen 你试试在heroku上手工添加一个postgresql数据库,然后在数据库设置里选择生成适合activemodel的配置,再把这个配置写到你的database.yml里。

用postgresQL数据库 Using pg:transfer to Migrate Postgres Databases heroku pg:transfer -f 本机的数据库地址 -t heroku的数据库地址

heroku 会直接忽视你的database配置文件的吧 重新commit push 一下 再试试

#11楼 @ghjcumt2008 麻烦详细解释一下你的命令呢 实在受不了啦,搞了好几天了,第一个部署的练习就一直没做成功,唉 谁帮帮我吧

http://nameless-savannah-7872.herokuapp.com/blog,主页是默认的rails欢迎页面,我没有动过的。这到底是哪的问题呢这就是这个地址,就算数据库没对,也应该能看到主页是吧?我是按示例做到个

heroku logs 贴出来看看

等下,我要重新启动虚拟机

我是按示例做到一个blog,主页是默认的,操作过程中也只有db:migrate失败了,访问网址是不是还是应该能看到主页呢

@shangchen 直接打heroku logs应该能看到错误提示信息 ,没找到问题的话贴出来看看

太多了,麻烦高手帮忙分析一下阿,非常感谢 heroku logs: 2013-06-07T14:10:42.153871+00:00 app[web.1]: from /app/vendor/bundle/ruby/1.9.1/gems/railties-3.2.12/lib/rails/railtie/configurable.rb:30:in method_missing' 2013-06-07T14:10:42.154336+00:00 app[web.1]: from script/rails:6:inrequire' 2013-06-07T14:10:42.153602+00:00 app[web.1]: from /app/vendor/bundle/ruby/1.9.1/gems/railties-3.2.12/lib/rails/engine.rb:438:in each' 2013-06-07T14:10:42.153602+00:00 app[web.1]: from /app/vendor/bundle/ruby/1.9.1/gems/railties-3.2.12/lib/rails/engine.rb:438:inblock in eager_load!' 2013-06-07T14:10:42.154336+00:00 app[web.1]: from script/rails:6:in <main>' 2013-06-07T14:10:43.322655+00:00 heroku[web.1]: Process exited with status 1 2013-06-07T14:10:43.340656+00:00 heroku[web.1]: State changed from starting to crashed 2013-06-07T14:12:29.614765+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/blog host=nameless-savannah-7872.herokuapp.com fwd="218.194.36.91" dyno= connect= service= status=503 bytes= 2013-06-07T14:12:37.461311+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="218.194.36.91" dyno= connect= service= status=503 bytes= 2013-06-07T14:12:37.994196+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="218.194.36.91" dyno= connect= service= status=503 bytes= 2013-06-07T14:14:48.197668+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/blog%EF%BC%8C%E4%B8%BB%E9%A1%B5%E6%98%AF%E9%BB%98%E8%AE%A4%E7%9A%84rails%E6%AC%A2%E8%BF%8E%E9%A1%B5%E9%9D%A2%EF%BC%8C%E6%88%91%E6%B2%A1%E6%9C%89%E5%8A%A8%E8%BF%87%E7%9A%84%E3%80%82%E8%BF%99%E5%88%B0%E5%BA%95%E6%98%AF%E5%93%AA%E7%9A%84%E9%97%AE%E9%A2%98%E5%91%A2 host=nameless-savannah-7872.herokuapp.com fwd="211.155.120.241" dyno= connect= service= status=503 bytes= 2013-06-07T14:14:51.690765+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="211.155.120.241" dyno= connect= service= status=503 bytes= 2013-06-07T14:14:52.088487+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="211.155.120.241" dyno= connect= service= status=503 bytes= 2013-06-07T14:16:59.043851+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/blog host=nameless-savannah-7872.herokuapp.com fwd="112.91.70.213" dyno= connect= service= status=503 bytes= 2013-06-07T14:16:59.851819+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="112.91.70.213" dyno= connect= service= status=503 bytes= 2013-06-07T14:17:01.069446+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="112.91.70.213" dyno= connect= service= status=503 bytes= 2013-06-07T14:17:02.285538+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=nameless-savannah-7872.herokuapp.com fwd="112.91.70.213" dyno= connect= service= status=503 bytes= 2013-06-07T14:17:02.993450+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/favicon.ico host=nameless-savannah-7872.herokuapp.com fwd="112.91.70.213" dyno= connect= service= status=503 bytes= 2013-06-07T14:20:44.920000+00:00 heroku[web.1]: State changed from crashed to starting 2013-06-07T14:20:47.473386+00:00 heroku[web.1]: Starting process with commandbundle exec rails server -p 13175 2013-06-07T14:20:57.147919+00:00 app[web.1]: DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins!

@shangchen 在线吗? 你没at我,刚看到,我还刷了几次,看没消息。。。

gemfile 里加thin了没? @shangchen

现在heroku的应用貌似要加这个gem才行。在线可以沟通下。。 别放弃,加油

#21楼 @xazaj 没有加,我马上试一下

#21楼 @xazaj 成功了,数据库也对了,非常感谢你啊!

成功就好,ruby其实很多东西可玩,遇到问题别气馁,过了这一个个坎就看见阳光了,加油!!@shangchen

遇到和你相同的问题,不过解决办法不一样,附上我的解决方法:

  1. 先添加一个 postgresqladd-on,启动数据库服务 $ heroku addons:add heroku-postgresql:dev
  2. 然后在 config 中找到 HEROKU_POSTGRESQL 的URL参数 $ heroku config | grep HEROKU_POSTGRESQL 我的输出显示是: $ HEROKU_POSTGRESQL_NAVY_URL: postgres://root@root 则这个参数是 HEROKU_POSTGRESQL_NAVY_URL
  3. 把这个URL参数指向 DATABASE_URL, 注意命令里的参数哦!! $ heroku pg:promote HEROKU_POSTGRESQL_NAVY_URL
  4. 再运行heroku run rake db:migrate就可以了!
