如何在新机器上为旧应用程序安装mysql？

我不知道该怎么做

我的应用程序的

数据库.yml

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: application-dev
  pool: 5
  username: root
  password: angles123
  socket: /tmp/mysql.sock

我在想，明智的做法是继续使用

mysqladmin-u root--password=angles123

，然后进入

创建数据库应用程序dev

，但是

-dev

部分，mysql并不满意。但是我可以创建一个简单的数据库，上面写着

应用程序

我可能还错过了什么吗

我之所以提出这个问题，是因为每当我尝试rake db:migrate或script/server时都会出现这个错误

rake db:test:prepare
(in /Users/macuser/Sites/hq_channel)
rake aborted!
uninitialized constant Geocode

所以我假设我设置了错误的数据库，因为我显然安装了gem

以下是完整的堆栈跟踪：

我安装的mysql不允许在数据库名称中使用下划线或破折号

您可以尝试将数据库名称更改为

application

，然后运行

rake db:create

，查看它是否创建了您的数据库

---

此外，您可以尝试使用

--trace

运行rake，以更好地了解导致该错误的地方包含了哪些内容。

我打赌geocode缺少一个library@sam，我尝试重新安装地理代码，但它不包括在我的配置文件中。但Geokit是。这两种方法都没有在我的应用程序中实际使用，这让我觉得有可能删除它对它的依赖关系吗？你会如何修复一个丢失的图书馆？我不知道是专门为Geokit做的。但是对于一些宝石，你需要给出一个路径来做库。您可以通过：lib=>'path/to/lib'来实现，例如config.gem'geokit'，：lib=>'path/to/geokit'@sam，该路径的根是什么？从我的应用程序来看，

gems/geokit-1.4.1/lib/geokit

嘿，我想你是对的。当我尝试

rake db:create（在/Users/macuser/Sites/application中）无法为{“reconnect”=>false，“encoding”=>“utf8”，“username”=>“rootsies”，“adapter”=>“mysql”，“database”=>“application”，“pool”=>5，“password”=>“angles1234”，“socket”=>“/tmp/mysql.sock”}创建数据库时，字符集：utf8，排序规则：utf8\u general\ci（如果手动设置字符集，请确保具有匹配的排序规则）

我还为root用户和我的用户设置了数据库的权限。你认为我缺少什么？听起来像是数据库连接或权限问题。也许你没有为非root用户创建权限？通过简单地在apache中更新我的LoadModules，rake db:CREATE就可以正常工作了。这些似乎需要升级一段时间64位计算机能够处理它。我为mysql做了arch标志。当我运行rake db:create时，它说它现在已经存在了。这样就可以了。但是如果我执行

rake db:migrate

或

rake db:test:prepare

或

script/server

blink更新Apache fixed mysql？哇哦。试试removi因为运行rake会加载您的应用程序，包括环境和初始值设定项，所以会禁用该初始值设定项（/config/initializers/geocode.rb）。
