Nginx+mongodb-gridfs+squid

圖片存儲

通過Nginx+mongodb-gridfs+squid實現簡單的圖片存儲及圖片緩存.

 

圖片先從nginx本地cache裏查找,然後到站點去找,再而到squid 裏查找,都找不到最後纔到mongodb-girdfs查找,然後把圖片cache到squid.

squid分2個地方存儲,小於250k的圖片存入內存,大於250K的圖片存在磁盤

 

cache_dir ufs /home/cache 400 16 256  max-size=250000

cache_dir ufs /var/spool/squid 2000 16 256   min-size=250000

通過把內存掛載到硬盤的方法,來把圖片保存至內存,提高訪問速度

訪問效果

 

Squid緩存效果,這時停掉後端的mongodb,訪問還是沒有問題的.圖片依然可以正常顯示
