我已经建立了一个新的Redmine 2.5.1安装于Ubuntu 12.04使用 apache2 和 Passenger 按照以下步骤操作：http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_on_Ubuntu_step_by_step
此后我
- 转储现有 Redmine 1.1.3.stable 安装的 mysql 数据库，
- 将其还原到我的新服务器上的新数据库，
- 将附件从旧服务器复制到新服务器 /usr/share/redmine/文件（+修改权限 755）
- 告诉redmine在数据库配置中使用我以前导入的票证和新创建的数据库。
- 将目录更改为 /usr/share/redmine 并触发此操作
rake db:migrate RAILS_ENV=production rake generate_secret_token
到目前为止一切顺利。可以在浏览器中查看 Redmine，可以在那里更改管理设置和项目。
但是，如果我尝试创建新票据或查看旧票据，则会收到错误 500。此外，Redmine 给我的版本是 1.1.3，但应该是 2.5.1。看来我可能忘了运行迁移脚本。
查找我创建的错误
- /usr/share/redmine/log/production.log
- chmod 755 生产.log
- 改变了我的 apache2 配置中的错误处理
LogFormat "%h %l %u %t \"%r\" %>s %b" common LogLevel WARN ErrorLog "/var/log/apache2/redmine-error.log" CustomLog "/var/log/apache2/redmine-access.log" common
但是我在 production.log、redmine-error.log、error.log 中看不到任何错误！？
我该如何修复错误 500 问题？
更新我设法让日志记录运行起来。以下是日志输出：

答案1
可以通过为 tmp 目录赋予 chmod 755 来解决该问题
