Nginx如何配置代理【附代码】

今天爱分享给大家带来Nginx如何配置代理【附代码】，希望能够帮助到大家。

Nginx的代理功能非常实用，例如一个没有公网IP的服务器想要访问远端web服务器，而它们并不相通，此时可以选择一台代理服务器作为跳板，代理服务器和web服务器相通，从而使服务器可以访问到远端web服务器。

[root@minglinux-01 ~] vim /usr/local/nginx/conf/vhost/proxy.conf  //新建proxy.conf文件
  1 server  
  2 {
  3     listen 80;
  4     server_name ask.apelearn.com;  //定义要访问的域名
  5 
  6     location /
  7     {
  8         proxy_pass      http://121.201.9.155/;  //proxy_pass指定要代
理的域名所在的服务器IP
  9         proxy_set_header Host   $host; //后面的三行为定义发往后端Web服务器的请求头
 10         proxy_set_header X-Real-IP      $remote_addr;
 11         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 12     }
 13 }

测试结果：

[root@minglinux-01 ~] /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@minglinux-01 ~] /usr/local/nginx/sbin/nginx -s reload
[root@minglinux-01 ~] curl ask.apelearn.com/robots.txt
