獨角獸大師未能開始

Question

我試圖通過nginx和獨角獸開始一個應用程序。 我成功啟動服務器3次類似的代碼。 但我通常會看到這個：

[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/gems/unicorn-5.1.0/lib/unicorn/configurator.rb:65:in `initialize'
    from /usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/lib/unicorn/http_server.rb:76:in `new'
    from /usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/lib/unicorn/http_server.rb:76:in `initialize'
    from /usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/bin/unicorn_rails:209:in `new'
    from /usr/local/rvm/gems/ruby-2.1.0/gems/unicorn-5.1.0/bin/unicorn_rails:209:in `<top (required)>'
    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

我怎么能解決這個問題？

Answer 1

正如錯誤消息中所述：

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

所以，

• 您需要為錯誤日志記錄設置不同的路徑

要么

• 你需要作為一個合適的用戶運行獨角獸

要么

• 你需要chown / change這個文件夾的權限
