# Nginx配置正向代理支持HTTP和HTTPS转发 #

> 嫌麻烦的朋友，可以用Squid来搭建，参见：[在CentOS7上设置Squid HTTP Proxy正向代理][CentOS7_Squid HTTP Proxy]

Nginx本身不支持HTTPS正向代理，需要安装`ngx_http_proxy_connect_module`模块后才可以支持HTTPS正向代理，否则会遇到`HTTP 400`错误。

参考文档：

## 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
