Ruby-on-Rails
rails cap部署獨角獸問題
試圖部署 Rails 應用程序。一切都安裝好nginx、unicorn、setup。
我得到的錯誤:
[109.etc] env RAILS_ENV=production sh -c 'kill -s USR2 '\''cat /tmp/unicorn.pid'\''' sh: line 0: kill: cat /tmp/unicorn.pid: arguments must be process or job IDs
如何解決這個問題?我搜尋了一個小時閱讀了許多文件和部落格文章,但仍然沒有找到解決方案。
部署.rb

更新
從伺服器執行 unicorn start 命令時:
bundle exec unicorn_rails -c config/unicorn.rb -D /usr/local/rvm/gems/ruby-1.9.3-p125/gems/bundler-1.1.1/lib/bundler.rb:255: warning: Insecure world writable dir /srv in PATH, mode 040777
我對 /srv/ drwxr–r– 4 root root 4096 Mar 15 19:14 srv 的權限 *不確定這些是否正確
unicorn_rails -E production -c $APP_PATH/config/unicorn.rb -D
應該是你所需要的。因此,查看您的程式碼,-E
如果您必須以這種方式使用 bundle,您將失去您的 env 標誌 ()。
