分享一份來自於線上的Nginx配置（Nginx.conf），對學習Nginx有很好的幫助

現分享一份Nginx的配置文件說明，是真正經歷過正式線上考驗過。若是有優化的地方，也請朋友們指點一二，整理出一份比較全而實用的配置。

主要包含配置：負載均衡配置，頁面重定向，轉發，HTTPS和HTTP的配置, 緩存優化，錯誤頁面配置等。

    worker_connections  2048;
	#優化同一時刻只有一個請求而避免多個睡眠進程被喚醒的設置，on爲防止被同時喚醒，默認爲off，所以nginx剛安裝完之後要進行適當的優化。
	accept_mutex on;
	#打開同時接受多個新網絡鏈接請求的功能
