Nginx配置正向代理
最近一个支付项目,需要访问外部支付接口,所以使用Nginx做一个正向代理,让其使用。
记录过程如下:
新增一个代理server
server {
resolver 114.114.114.114; #指定DNS服务器IP地址
listen 192.168.0.28:10080;
location / {
proxy_pass http://$host; #设定代理服务器的协议和地址
proxy_set_header HOST $host;
proxy_buffers 256 4k;
proxy_max_temp_file_size 0k;
proxy_connect_timeout 30;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_next_upstream error timeout invalid_header http_502;
}
}
重启服务后,在另一台服务器上测试是否可用
[root@appserver33 APP]# curl -I http://www.qq.com -x 192.168.0.28:10080
HTTP/1.1 302 Moved Temporarily
Server: nginx/1.20.1
Date: Fri, 17 Dec 2021 10:19:19 GMT
Content-Type: text/html
Content-Length: 151
Connection: keep-alive
Location: https://www.qq.com/
# 通过全局设置代理
[root@appserver33 APP]# export http_proxy='192.168.0.28:10080'
[root@appserver33 APP]# curl -I http://www.qq.com
HTTP/1.1 302 Moved Temporarily
Server: nginx/1.20.1
Date: Fri, 17 Dec 2021 10:22:12 GMT
Content-Type: text/html
Content-Length: 151
Connection: keep-alive
Location: https://www.qq.com/
通过代理访问http协议以实现。
发现问题,无法访问https协议
[root@appserver33 APP]# curl -I https://www.qq.com -x 192.168.0.28:10080
HTTP/1.1 400 Bad Request
Server: nginx/1.20.1
Date: Fri, 17 Dec 2021 10:26:41 GMT
Content-Type: text/html
Content-Length: 157
Connection: close
curl: (56) Received HTTP code 400 from proxy after CONNECT
通过查找资料发现: 默认nginx没有加载https的代理模块,通过打补丁的方式,然后编译安装就可以。

我这里因为只需要代理http协议,就没有往下走了。
传统的正向代理软件还有: squid
