我想提供存储在不同服务器上的静态文件。为此,我使用具有以下配置的 Nginx 缓存。
Nginx 缓存配置:
proxy_cache_path /var/cache/cdn levels=1:2 keys_zone=cdn:64m max_size=20g inactive=10m use_temp_path=off;
服务配置:
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name <server-name>;
ssl_certificate <fullchain>;
ssl_certificate_key <key>;
location / {
# Activate caching
proxy_cache cdn;
# Cache becomes stale after 1 minute
proxy_cache_valid 1m;
# Download stale data only if it has been modified on origin
proxy_cache_revalidate on;
# Use stale file origin is unaccessible
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
# If multiple clients get a MISS for the same file,
# the file is downloaded form Origin only once
proxy_cache_lock on;
# Filesystem key
proxy_cache_key $uri$is_args$args;
# Gives the status of the file returned
# MISS, BYPASS, EXPIRED, STALE, UPDATING, REVALIDATED, HIT
add_header X-Cache-Status $upstream_cache_status;
# Origin server address
proxy_pass <server origin>;
}
}
server{
listen 80;
listen [::]:80;
server_name <server-name>;
if ($host = <server-name>) {
return 301 https://$host$request_uri;
}
}
此设置全局工作正常:文件已交付,重新验证工作,proxy_cache_valid 也工作......但是,inactive
参数 inproxy_cache_path
似乎根本不起作用:在没有任何人请求文件的情况下 10 分钟后,所述文件未被删除缓存并且仍然可以在 /var/cache/cdn 目录中看到。
这是正常的吗?我搞砸了我的配置吗?
感谢您的帮助,
