http{
...
proxy_cache_path /usr/share/nginx/proxy_cache_dir levels=1:2 keys_zone=cache_one:200m inactive=1d max_size=30g; # 参数分别是缓存存放路径,levels表示使用几级缓存目录,keys_zone表示从内存中抽出多大空间,inactive表示存取多长时间后过期,max_size表示最大使用空间
...
}
server {
...
proxy_cache cache_one; # 启用缓存,缓存ID为cache_one
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
proxy_cache_valid 200 304 12h; #对不同的HTTP状态码设置不同的缓存时间
proxy_cache_key $request_uri;
