Nginx配置正向代理支持HTTP和HTTPS转发

1、Nginx不支持https，如果想要使用需要安装以下的补丁

参考文档：

https Nginx补丁

https://github.com/chobits/ngx_http_proxy_connect_module

安装编译环境和工具

yum install gcc gcc-c++ autoconf automake -y

yum install pcre pcre-devel -y

yum install openssl openssl-devel -y

yum install patch -y

yum install git -y

yum install net-tools -y

安装Nginx和ngx_http_proxy_connect_module模块

mkdir -p /downloads

cd /downloads

git clone https://github.com/chobits/ngx_http_proxy_connect_module.git

wget http://Nginx.org/download/Nginx-1.15.12.tar.gz

tar -xzvf Nginx-1.15.12.tar.gz

cd Nginx-1.15.12/

patch -p1 < /downloads/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_101504.patch

./configure --add-module=/downloads/ngx_http_proxy_connect_module

make && make install

修改Nginx配置文件

Nginx目录：/usr/local/Nginx

修改Nginx目录下conf/Nginx.conf配置文件，在http中添加以下内容：

server {  

    resolver 114.114.114.114; 

    listen 8080;  

    location / {  

        proxy_pass http://$http_host$request_uri;

        proxy_set_header HOST $http_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;

    }  

}

server {

     listen                         8443;

     # dns resolver used by forward proxying

     resolver                       114.114.114.114;

     # forward proxy for CONNECT request

     proxy_connect;

     proxy_connect_allow            443 563;

     proxy_connect_connect_timeout  10s;

     proxy_connect_read_timeout     10s;

     proxy_connect_send_timeout     10s;

     # forward proxy for non-CONNECT request

     location / {

         proxy_pass http://$host;

         proxy_set_header Host $host;

     }

 }

启动Nginx

运行./sbin/Nginx启动Nginx。

Nginx命令参考：

# Start Nginx

./sbin/Nginx

# Reload Nginx configuration

./sbin/Nginx -s reload

# Stop Nginx

./sbin/Nginx -s stop

查看端口

netstat -tnlp | grep 8080

netstat -tnlp | grep 8443

打开防火墙

firewall-cmd --zone=public --add-port=8080/tcp

firewall-cmd --zone=public --add-port=8080/tcp --permanent

firewall-cmd --zone=public --add-port=8443/tcp

firewall-cmd --zone=public --add-port=8443/tcp --permanent

firewall-cmd --reload

测试代理

# Test HTTP proxy

curl --proxy 192.168.87.123:8080 http://www.baidu.com

# Test HTTPS proxy

curl --proxy 192.168.87.123:8443 https://www.baidu.com

客户端需要设置代理

export http_proxy="http://192.168.87.123:8080"

export https_proxy="http://192.168.87.123:8443"

如果永久生效需要写在/etc/profile文件中

source /etc/pofile 进行生效
