Nginx动静分离+proxy_cache缓存

nginx的动静分离和proxy_cache缓存可以同时设置，感觉在集群部署时可能效果更好。

一．http模块增加缓存设置

    proxy_temp_path /etc/nginx/proxy_temp;   
    proxy_cache_path /etc/nginx/proxy_cache levels=1:2 keys_zone=cache_one:200m inactive=5d max_size=1g;
    inactive=5d max_size=1g;
    proxy_ignore_headers X-Accel-Expires Expires Cache-Control Set-Cookie;

二．Server模块

动静分离和缓存的结合（经测试研究，nginx如果做了动静分离，自带的proxy_cache模块来无法实现nginx缓存自身代理的静态页面，所以再加一个server端，方便缓存配置和集群部署）

    server {
        listen       80;
        server_name  www.nginx2.com;
        #静态处理交给nginx
        location ~ .*\.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|ico|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma|css|js)$ {
            proxy_cache cache_one;
            proxy_cache_valid 200 304 302 2d;
            proxy_cache_valid any 1d;
            proxy_cache_key $host$uri$is_args$args;
            add_header X-Cache '$upstream_cache_status from $host';
            proxy_pass http://127.0.0.1:8088;
            expires 30d;
        }
        #动态文件不处理
        location ~ .*$ {
            proxy_pass http://127.0.0.1:8080;
            proxy_cookie_path /nginx1/ /;
        }
}
    server{
        listen 8088;
        location ~ .*\.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|ico|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma|css|js)$ {
            root /opt/apache-tomcat-7.0.64/webapps/nginx1;
            expires 30d;
        }
    }
