为 Silo 服务端配置 NGINX 代理

以下文档提供了在 Linux 环境中配置 NGINX 将请求代理到 MinIO 的基线方案。这并非一份关于 NGINX、代理或反向代理的一般性完整指南。请根据你的基础设施需要调整配置。

本文档基于以下前提：

已有 NGINX 部署
已有 MinIO 部署
一个可唯一标识该 MinIO 部署的 DNS 主机名

将请求代理到 MinIO 服务端 API 和 MinIO Console 有两种模式：

为 MinIO 服务创建或配置一个专用 DNS 名称。

对于 MinIO Server S3 API，将请求代理到该域名的根路径。对于 MinIO Console Web GUI，将请求代理到 /minio 子路径。

例如，给定主机名 minio.example.net：

将对根路径 https://minio.example.net 的请求代理到监听于 https://minio.local:9000 的 MinIO Server。
将对 https://minio.example.net/minio/ui 子路径的请求代理到监听于 https://minio.local:9001 的 MinIO Console。

以下 location 块提供了模板，可在你的环境中进一步定制：

upstream minio_s3 {
   least_conn;
   server minio-01.internal-domain.com:9000;
   server minio-02.internal-domain.com:9000;
   server minio-03.internal-domain.com:9000;
   server minio-04.internal-domain.com:9000;
}

upstream minio_console {
   least_conn;
   server minio-01.internal-domain.com:9001;
   server minio-02.internal-domain.com:9001;
   server minio-03.internal-domain.com:9001;
   server minio-04.internal-domain.com:9001;
}

server {
   listen       80;
   listen  [::]:80;
   server_name  minio.example.net;

   # Allow special characters in headers
   ignore_invalid_headers off;
   # Allow any size file to be uploaded.
   # Set to a value such as 1000m; to restrict file size to a specific value
   client_max_body_size 0;
   # Disable buffering
   proxy_buffering off;
   proxy_request_buffering off;

   location / {
      proxy_set_header Host $http_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;

      proxy_connect_timeout 300;
      # Default is HTTP/1, keepalive is only enabled in HTTP/1.1
      proxy_http_version 1.1;
      proxy_set_header Connection "";
      chunked_transfer_encoding off;

      proxy_pass https://minio_s3; # This uses the upstream directive definition to load balance
   }

   location /minio/ui/ {
      rewrite ^/minio/ui/(.*) /$1 break;
      proxy_set_header Host $http_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;
      proxy_set_header X-NginX-Proxy true;

      # This is necessary to pass the correct IP to be hashed
      real_ip_header X-Real-IP;

      proxy_connect_timeout 300;

      # To support websockets in MinIO versions released after January 2023
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      # Some environments may encounter CORS errors (Kubernetes + Nginx Ingress)
      # Uncomment the following line to set the Origin request to an empty string
      # proxy_set_header Origin '';

      chunked_transfer_encoding off;

      proxy_pass https://minio_console; # This uses the upstream directive definition to load balance
   }
}

S3 API 签名计算算法不支持将 MinIO Server API 托管在 example.net/s3/ 这类路径上的代理方案。

你还必须为 MinIO 部署设置以下环境变量：

将 MINIO_BROWSER_REDIRECT_URL 设置为 MinIO Console 代理主机的 FQDN（https://example.net/minio/ui）

为 MinIO Server S3 API 和 MinIO Console Web GUI 分别创建或配置独立且唯一的子域名。

例如，给定根域 example.net：

将对 minio.example.net 子域名的请求代理到监听于 https://minio.local:9000 的 MinIO Server
将对 console.example.net 子域名的请求代理到监听于 https://minio.local:9001 的 MinIO Console

S3 API 签名计算算法不支持将 MinIO Server API 托管在子路径上的代理方案，例如 minio.example.net/s3/。

你还必须为 MinIO 部署设置以下环境变量：

将 MINIO_BROWSER_REDIRECT_URL 设置为 MinIO Console 代理主机的 FQDN（https://console.example.net/）
