nginx正向代理http，nginx正向代理https

正向代理，指的是通过代理服务器 代理浏览器/客户端去重定向请求访问到目标服务器 的一种代理服务。正向代理服务的特点是代理服务器 代理的对象是浏览器/客户端，也就是对于目标服务器 来说浏览器/客户端是隐藏的。nginx默认支持正向代理http，不支持httpsnginx官方并不支持直接转发https请求，nginx支持https需要ngx_http_proxy_connect_module模块。github上开源了模块 https://github.com/chobits/ngx_http_proxy_connect_module。不过维护的ngx_http_proxy_connect_module模块的补丁也是有nginx版本限制的，需根据自身使用的nginx版本选择相应的正向代理模块。可以在REDEME.md的Select patch中查看nginx版本和模块的对应关系

安装包准备

配置正向代理

cd /usr/local/nginx/ #gzip on;下添加 vim conf/nginx.conf #gzip on; #正向代理转发http请求 server { #指定DNS服务器IP地址 resolver 114.114.114.114; #监听80端口，http默认端口80 listen 80; #服务器IP或域名 server_name localhost; #正向代理转发http请求 location / { proxy_pass http://$host$request_uri; proxy_set_header HOST $host; proxy_buffers 256 4k; proxy_max_temp_file_size 0k; proxy_connect_timeout 30; proxy_send_timeout 60; proxy_read_timeout 60; proxy_next_upstream error timeout invalid_header http_502; } } #正向代理转发https请求 server { #指定DNS服务器IP地址 resolver 114.114.114.114; #监听443端口，https默认端口443 listen 443; #正向代理转发https请求 proxy_connect; proxy_connect_allow 443 563; proxy_connect_connect_timeout 10s; proxy_connect_read_timeout 10s; proxy_connect_send_timeout 10s; location / { proxy_pass http://$host; proxy_set_header Host $host; } }

创建nginx用户

nginx服务以用户nginx身份启动

useradd nginx

检查nginx配置并启动

sbin/nginx -t sbin/nginx ss -utnlp | grep nginx tcp LISTEN 0 511 *:443 *:* users:((“nginx”,pid=6645,fd=7),(“nginx”,pid=6644,fd=7)) tcp LISTEN 0 511 *:80 *:* users:((“nginx”,pid=6645,fd=6),(“nginx”,pid=6644,fd=6))

nginx服务所在服务器验证正向代理功能

配置不能访问外网的服务器（即内网服务器）,使其可以访问外网

liunx服务器配置

1.只配置使用yum时，能够使用正向代理访问外网

#追加配置 vim /etc/yum.conf proxy=http://192.168.0.20:80 #nginx正向代理服务器的地址 proxy=ftp://192.168.0.20:80 #nginx正向代理服务器的地址

2.只配置使用wget时，能够使用正向代理访问外网

#追加配置 vim /etc/wgetrc http_proxy=192.168.0.20:80 #nginx正向代理服务器的地址 http_proxy=192.168.0.20:443 #nginx正向代理服务器的地址

3.全局配置，所以访问请求都能够使用正向代理访问外网

#追加配置 vim /etc/profile http_proxy=192.168.0.20:80 https_proxy=192.168.0.20:443 ftp_proxy=192.168.0.20:443 export http_proxy export https_proxy export ftp_proxy # 加载配置 source /etc/profile

windows服务器配置
