nginx做cache其实也比较简单。配置项非常少

#user  nobody;
worker_processes  1;
error_log  logs/error.log;
pid        logs/nginx.pid;

events {worker_connections 65535;}

http {include       mime.types;
default_type  application/octet-stream;
underscores_in_headers on;
log_format  main  ‘$http_orig_client_ip  $remote_addr $host – $remote_user [$time_local] "$request" ‘‘$status $body_bytes_sent "$http_referer" ‘‘"$http_user_agent" "$http_x_forwarded_for"’;

}}


如果是想把内容放内存，可以把缓存的路径设置到shm里面。
