【问题描述】：

我尝试通过 nginx & unicorn 启动应用程序。我成功启动服务器 3 次，再见类似的代码。但我通常会看到这个：

[root@server yaqoot]# unicorn_rails -c config/unicorn.rb -D
/usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/lib/unicorn/configurator.rb:88:in `block in reload': directory for stderr_path=/var/www/yaqoot/log/unicorn/log not writable (ArgumentError)

    from /usr/local/rvm/gems/ruby-2.1.0/bin/ruby_executable_hooks:15:in `<main>'
master failed to start, check stderr log for details

我该如何解决这个问题？

标签： ruby-on-rails ruby nginx unicorn

【解决方案1】：

正如错误消息中所述：

/var/www/yaqoot/log/unicorn/log not writable

所以，

您需要为错误日志设置不同的路径

或

您需要以适当的用户身份运行 unicorn

或

您需要更改/更改此文件夹的权限
