上面说数据库不适配,我的 database.yml 设置跟另一个运行正常的的文件模板一样的,我想不是 database.yml 的原因。。

————————————————————————————

还有一个重要的信息:::项目启动了之后,数据库中没有生成对应的数据库!

运行一个叫做 rain 的项目能够正常运转 ,换成别的项目就不行了,(nginx.conf 已经修改),已经尝试多个项目,都无法正常运行,,

rake db:migrate 这个?

#1 楼 @hging 实在服务器中部署额!!部署完后直接启动项目了!!!我记得不需要自行迁移数据库!

#2 楼 @sensi 你是怎么部署的呢- - 直接 rails s?

bundle install
RAILS_ENV=production rake db:create
RAILS_ENV=production rake db:migrate
RAILS_ENV=production rake db:seed
RAILS_ENV=production rake assets:precompile
rails s -e production

#3 楼 @hging sudo /etc/init.d/nginx restart 很早之前有一个项目在这运行,现在换了项目,一直部署不成功

#5 楼 @sensi ........看 4L 并且 nginx 只是个代理啊. 没起程序啊.

#6 楼 @hging 已经通过四楼的方式 运行成功 谢谢,,,但是图片上传不能成功!开发的时候上传是成功的!

#7 楼 @sensi 果然还是没有添加数据库. 嘿嘿. 那你图片上传的话是怎么上传的么. 具体有没有什么报错信息 and 代码呢.

#8 楼 @hging用 carrierwave 上传的,访问页面给的错误提示是:If you are the application owner check the logs for more information. 但是 production.log 里面没有任何的信息,
