+description: "为 RustFS实现Nginx反向代理的配置"
+---
+
+# 一、RustFS Nginx 前置条件
+
+为了让集成顺利进行，你需要提前准备了：
+
+1. RustFS Server 安装正常，并且正确启动；
+2. 确定RustFS的端口；
+3. Nginx标识正确；
+4. 确认RustFS 单机或者集群的IP地址。
+
+
+
+# 二、 配置文件
+
+
+~~~
+
+
+upstream rustfs {
+   least_conn;
+   server 127.0.0.1:9000;
+}
+server {
+   listen       8000;
+   listen  [::]:8000;
+   server_name  _;
+
+   # 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_set_header Upgrade $http_upgrade;
+      proxy_set_header Connection "upgrade";
+
+
+
+
+      proxy_pass http://rustfs; # This uses the upstream directive definition to load balance
+   }
+}
+
+~~~
+
+
+# 三、多机负载均衡
+
+
+若需要在分布式环境中增加多个RustFS服务器，请提前调整好DNS解析或者本地的Hosts地址，修改和增加 server即可。
+
+~~~
+upstream rustfs {
+   least_conn;
+   server 10.0.0.1:9000;
+   server 10.0.0.2:9000;
+   server 10.0.0.3:9000;
+   server 10.0.0.4:9000;
+}
