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, the memory cache space size is 200mb,1 days without access to the content is automatically cleared, the hard disk cache space size is 30GB Proxy_cache_path/var/imgcache Test 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 304 12h;        #以域名, URI, parameters combined into the Web cache key value, Nginx based on the key value hash, storage cache content to the level two cache directory Proxy_cache_key $host $uri$is_args$args;        Proxy_set_header Host $host;        Proxy_set_header x-forwarded-for $remote _addr;        Proxy_pass http://127.0.0.1:8080;    Expires 1d; }e}

4. When you access the test picture, a picture cache is generated in the/var/imgcachetest directory, complete.
