配置文件

/etc/nginx/nginx.conf

典型配置

worker_processes 1;

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;
        server_name example.com;
        location / {
            root /var/www/example.com;
            index index.html index.htm;
        }
    }
}

配置请求转发

http {
    server {
        listen 80;

        location / {
            proxy_pass http://localhost:8080;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
        }
    }
}

需要注意的是，在这段配置中使用了 proxy_set_header 设置的三个请求头，分别是 Host、X-Real-IP 和 X-Forwarded-For。

这三个请求头的目的是告诉服务端当前请求的来源
