独角兽大师启动失败

Question

我尝试通过 nginx 和 unicorn 启动应用程序。我成功启动服务器 3 次再见类似代码。但我经常看到这个：

[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/gems/unicorn-5.1.0/lib/unicorn/configurator.rb:84:in `each'
    from /usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/lib/unicorn/configurator.rb:84:in `reload'

    from /usr/local/rvm/gems/ruby-2.1.0/bin/unicorn_rails:23:in `load'
    from /usr/local/rvm/gems/ruby-2.1.0/bin/unicorn_rails:23:in `<main>'
    from /usr/local/rvm/gems/ruby-2.1.0/bin/ruby_executable_hooks:15:in `eval'
    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？

Answer 1

如错误消息中所述：

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

所以，

您需要为错误记录设置不同的路径

或

你需要运行独角兽作为一个合适的用户

或

您需要chown/change此文件夹的权限
