在Rails應用程序（Redmine）中使用Thin進行的權限被拒絕

Question

我試圖用Thin和nginx作爲反向代理運行Redmine。

我/etc/thin2.1/redmine.yml：

--- 
pid: /var/run/thin/redmine.pid 
group: redmine 
wait: 30 
timeout: 30 
log: /var/log/thin/redmine.log 
max_conns: 1024 
require: [] 

environment: production 
max_persistent_conns: 512 
servers: 4 
daemonize: true 
user: redmine 
socket: /var/run/thin/redmine.sock 
chdir: /var/www/projects.mydomain.tld 

當我與我的Web瀏覽器訪問該網站，我收到了502 Bad Gateway。這是/var/log/thin/redmine.0.log內容：

     from /usr/lib/ruby/vendor_ruby/thin/runner.rb:151:in `run!' 
     from /usr/bin/thin:6:in `<main>' 

我不明白是什麼原因導致這個錯誤。 /var/run/thin/中的.pid文件歸root所有。我試圖給予redmine和thin的所有權，但得到了相同的錯誤（這些文件在重新啓動時重新創建）。

我用rbenv安裝了Ruby。我以root身份運行bundle install，因爲這樣做will break this application for all non-root users on this machine。根據this answer這不應該是一個問題，應該嗎？

編輯：如果我在/etc/thin2.1/redmine.yml設置用戶和組root Permission denied錯誤消失。我雖然是在造成另一個錯誤，但那個仍然存在。

對於unlink文件權限過程實際上需要一個權限來寫入該文件的目錄。

於是要麼放棄寫/var/run/thin/或地方PID和插座別處redmine許可 - 通常是內部應用程序的共享tmp，軌道甚至爲這些創造迪爾斯。
