nginx的一点小用法-代理国外s3对象存储加速

缘由：

有一套环境部署在aws 新加坡区，资源使用s3对象存储，也用了cloudfront加速，但是but国内访问最近抽筋，也特意看了一下解析的地址IP....加速的地址在usa.....资源加速太慢了就想到了用nginx缓存加速一下！当然了还可以用国内腾讯云cos or 阿里云oss同步到国内？但是生命周期，同步成本估计会很高，就简单用nginx先尝试一下了！

顺便尝试问了一下chatgpt:

简单配置使用

就这样简单配置了一下：
cat xxx.xxx.com.conf

proxy_cache_path /data/wwwroot/xxx.xxx.com levels=1:2 keys_zone=s3_cache:10m max_size=1g inactive=60m use_temp_path=off;

server {
  listen 80;
  listen 443 ssl http2;
  ssl_certificate /usr/local/tengine/conf/ssl/xxx.com.crt;
  ssl_certificate_key /usr/local/tengine/conf/ssl/xxx.com.key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
  ssl_ciphers TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:TLS13-AES-128-CCM-8-SHA256:TLS13-AES-128-CCM-SHA256:EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
  ssl_prefer_server_ciphers on;
  ssl_session_timeout 10m;
  ssl_session_cache builtin:1000 shared:SSL:10m;
  ssl_buffer_size 1400;
  add_header Strict-Transport-Security max-age=15768000;
  ssl_stapling on;
  ssl_stapling_verify on;
  server_name xxx.xxx.com;
  access_log /data/wwwlogs/xxx.xxx.com_nginx.log combined;
  index index.html index.htm index.php;
  root /data/wwwroot/xxx.xxx.com;
  if ($ssl_protocol = "") { return 301 https://$host$request_uri; }

  include /usr/local/tengine/conf/rewrite/none.conf;
  #error_page 404 /404.html;
  #error_page 502 /502.html;

location / {
    proxy_http_version 1.1;
    proxy_pass http://xxx.s3.ap-southeast-1.amazonaws.com;
    proxy_set_header Authorization ""; 
    proxy_hide_header x-amz-id-2;
    proxy_hide_header x-amz-request-id;
    proxy_hide_header Set-Cookie;
    proxy_ignore_headers "Set-Cookie";
    proxy_cache s3_cache;
    proxy_cache_valid 200 302 1h;
    proxy_cache_valid 403 404 500 502 503 504 1m;
    add_header X-Cache-Status $upstream_cache_status;
}
}

注意：nginx server 使用oneinstack搭建，用了十多年的一键lnmp搭建工具！只增加了proxy_cache_path 配置，修改了location 配置。
reload 加载配置！

systemctl restart nginx 
or
systemctl reload nginx

完美实现，跟小伙伴开玩笑，打钱哈哈哈

有同样需求的可以尝试用nginx代理一下，当然了缓存时间，缓存文件最大大小等参数有必要根据实际优化一下！
