Nginx+proxy_cache Picture Cache

The principle of building image caching mechanism is to reduce the burden of database and speed up the response of static resources.

Steps:

1.vim /usr/local/nginx/conf/nginx.conf

2.

http{      ...      ...      #设置Web缓存区名称为cache_one，内存缓存空间大小为200MB，1天没有被访问的内容自动清除，硬盘缓存空间 大小为30GB      proxy_cache_path  /var/imgcachetest levels=1:2 keys_zone=cache_one:200m inactive=1d max_size=30g; }Where/var/imgcachetest is the mkdir image cache directory. 3. server{      ...           location / {          proxy_cache cache_one;          proxy_cache_valid  200 304 12h;          #以域名、URI、参数组合成Web缓存的Key值，Nginx根据Key值哈希，存储缓存内容到二级缓存目录内           proxy_cache_key $host$uri$is_args$args;          proxy_set_header Host  $host;          proxy_set_header X-Forwarded-For  $remote_addr;          proxy_pass http: //127 .0.0.1:9000;          expires      1d;      }e }4. When you access the test picture, a picture cache is generated in the/var/imgcachetest directory, complete.
