mysql - 您的 config/database.yml 可能编写不正确。请检查并修复任何错误

Question

我正在尝试在 Ubuntu 系统上安装 redmine，我相信它应该可以正确运行。但似乎卡在这里:

Your config/database.yml may not be written correctly. Please check it and fix any errors.
Your database schema may be out of date or nonexistant. Please run rake db:migrate to ensure that the database schema is up-to-date.
The database server may not be running. Please check whether it's running, and start it if it isn't.

我的database.yml设置正确，mysql正在运行并且凭据正确。

production:
adapter: mysql
database: myredminedb
host: localhost
username: redmine
password: password
encoding: utf8w

目前为 http://track.hutber.com/使用单独的虚拟主机:

<VirtualHost *:80>
        DocumentRoot /var/www/hutber.com/track.hutber.com
        ServerName track.hutber.com

    <Directory /var/www/hutber.com/track.hutber.com>
       Options FollowSymLinks
       RailsBaseURI /usr/share/redmine
       PassengerResolveSymlinksinDocumentRoot on               
       AllowOverride None
     </Directory>
</VirtualHost>

我完全被难住了。我自己就是一个 php 人...

运行 rake db:migrate 后

RAILS_ENV=production rake db:migrate
(in /usr/share/redmine)

Answer 1

您需要从应用程序根目录运行rake db:migrate。那将是包含文件 Rakefile 的目录。从你的问题的细节来看不确定，但我猜你需要这样做:

cd /var/www/hutber.com/track.hutber.com
RAILS_ENV=production rake db:migrate

更新

并将 database.yml 中的字符集更改为 utf8。当前设置为 utf8w
