我已经在aws上创build了一个私有存储桶，我想用nginx来反向代理它。 我为所有不同的代理使用了相同的服务器。 这是nginx的configuration文件：
user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { server_names_hash_bucket_size 64; server { listen 80; server_name ec2-...-...-....eu-central-1.compute.amazonaws.com; rewrite ^(.*) https://$host$1 permanent; } server { listen 443; server_name ec2-...-...-....eu-central-1.compute.amazonaws.com; ssl_certificate /etc/nginx/ssl/server.crt; ssl_certificate_key /etc/nginx/ssl/server.key; ssl on; ssl_session_cache builtin:1000 shared:SSL:10m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4; ssl_prefer_server_ciphers on; access_log /var/log/nginx/ssl_access.log; location ^~ / { #proxy_set_header x-real-IP $remote_addr; #proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for; #proxy_set_header host $host; #proxy_pass https://url.com; #proxy_set_header Host $host; #proxy_set_header X-Real-IP $remote_addr; #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #proxy_set_header X-Forwarded-Proto $scheme; # Fix the “It appears that your reverse proxy set up is broken" error. proxy_pass https://url.com; proxy_read_timeout 30; proxy_ssl_session_reuse off; proxy_ssl_verify off; } location /one/service { # proxy_set_header X-Real-IP $remote_addr; # proxy_set_header Host $host; # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://beanstalk-4.212314.eu-central-1.elasticbeanstalk.com/; proxy_read_timeout 30; proxy_ssl_session_reuse off; proxy_ssl_verify off; } location /privateproxy { set $s3_bucket 'bucketname.s3.eu-central-1.amazonaws.com'; set $aws_access_key 'AWSAccessKeyId=mykey'; set $url_expires 'Expires=$arg_e'; set $url_signature 'Signature=$arg_st'; set $url_full '$1?$aws_access_key&$url_expires&$url_signature'; proxy_http_version 1.1; proxy_set_header Host $s3_bucket; proxy_set_header Authorization ''; proxy_hide_header x-amz-id-2; proxy_hide_header x-amz-request-id; proxy_hide_header Set-Cookie; proxy_ignore_headers "Set-Cookie"; proxy_buffering off; proxy_intercept_errors on; resolver 172.16.0.23 valid=300s; resolver_timeout 10s; proxy_pass http://$s3_bucket/$url_full; } } } 但我得到502错误的网关我在configuration中做了什么错误？

如果存储桶名称正确，则解决问题。 描述的IP地址：172.16.0.23 仅用作非VPC EC2的 DNS服务器。 如果你使用VPC，解析器应该等于你想要的：
cat /etc/resolv.conf
例如，10.0.1.0/16 VPC子网可能会将10.0.1.2分配为内部解析器。 如果你不知道使用哪一个（VPC / non-VPC），那么打开DNS应该有帮助：
resolver 8.8.8.8;
请确保您指定了合理的S3存储桶名称：
set $s3_bucket '-->>bucketname.s3.eu-central-1.amazonaws.com';
