Nginx反向代理配置

• 1. 反向代理常用配置
• 2. 根据请求path进行转发

1. 反向代理常用配置

• 安装完nginx后，进入../nginx/conf路径下，打开nginx.cnf配置文件

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

}

• 配置文件新增内容

以下这些是location的基本配置，是通用的。服务器就能知道客户端的详细请求信息了

  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-NginX-Proxy true;

• 剩下的请求经过的location

 location / {
            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-NginX-Proxy true;

            proxy_pass http://exam.bittechblog.com:8081 ;
            root   html;
            index  index.html index.htm;
        }

2. 根据请求path进行转发

• 根据url中path来进行路由的location

# domain-name:80/api/user/url=>ip:port/url
        location ^~/roncopay/ {
            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-NginX-Proxy true;
            proxy_pass http://exam.bittechblog.com:8080/;
        }

开发者可以配置相应的请求转发到你的服务上。
