Migration
Redmine 數據遷移中斷安裝（錯誤 500）
我正在嘗試遷移舊的安裝：
Environment: Redmine version 2.2.3.stable Ruby version 1.9.3 (x86_64-linux) Rails version 3.2.12 Environment production Database adapter Mysql2 Redmine plugins: no plugin installed到新機器：

Internal error An error occurred on the page you were trying to access. If you continue to experience problems please contact your Redmine administrator for assistance. If you are the Redmine administrator, check your log files for details about the error. Back我得到以下日誌：

對我感到羞恥：
事實證明，我錯誤地期望
rake db:migrate對 採取行動productionENV，但事實並非如此。正確的命令是：
rake db:migrate RAILS_ENV="production".當您盲目地複制和粘貼時，就會發生這種情況。
抱歉打擾了（版主可以刪除此問答，如果他們認為它可能有用）。
作為記錄：您還需要在進行還原之前刪除 redmine_production 中的所有表，否則
rake ...命令將失敗並出現錯誤：Mysql2::Error: Table 'queries_roles' already exists: CREATE TABLE `queries_roles` (`query_id` int(11) NOT NULL, `role_id` int(11) NOT NULL) ENGINE=InnoDB/var/lib/gems/1.9.1/gems/activerecord-3.2.21/lib/active_record/connection_adapters/abstract_mysql_adapter.rb:245:in `query'
