Question

我在digitalocean上使用Ruby on Rails设置了一个Droplet，我删除了rails目录（App）并将其替换为我本地的目录。它工作正常，如果我连接到ssh并使用端口3000转到IP。但是每当我尝试转到端口80时，它会抛出一个错误： http://prntscr.com/2qoljb

我检查了日志，并说出以下内容：

Rails Error: Unable to access log file. Please ensure that /home/rails/log/production.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

表格应该存在，因为一切都工作得很好，如果我用端口3000手动输入IP ...

感谢您的提前帮助

修改设置权限和所有者后，我收到以下错误：

Answer 1

前两行明确说明了错误的文件权限，但Unicorn进程应该在与创建的日志文件相同的用户下运行。我猜capistrano和Unicorn在不同的用户下运行。

如果您不确定用户应该是什么，并且您没有安全问题，请运行：

$ chmod 0666 /home/rails/log/production.log

重新启动Unicorn之后，问题就会消失。

Answer 2

我现在不关心日志文件的问题。我认为这不是根本原因。

引起我注意的是Could not find table 'users'。该应用程序在数据库中找不到表users或根本找不到数据库。是否在config/database.yml中检查了您对生产数据库的凭据？您是否在数据库上运行迁移？也许连接到生产数据库并检查模式是否与您期望的一样。
