nginx正向代理http和https的实现步骤
配置准备正向代理，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https
nginx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（目前维护了1.4.x~1.19.x版本）
可以在REDEME.md的Select patch中查看nginx版本和模块的对应关系

此处用的是nginx-1.17.6，对应proxy_connect_rewrite_1018.patch
配置nginx正向代理
下载后上传到服务器
ls
ngx_http_proxy_connect_module-master.zip nginx-1.17.6.tar.gz
解压nginx，解压模块并重命名
tar xf nginx-1.17.6.tar.gz
unzip ngx_http_proxy_connect_module-master.zip
mv ngx_http_proxy_connect_module-master ngx_http_proxy_connect_module
ls
ngx_http_proxy_connect_module nginx-1.17.6 ngx_http_proxy_connect_module-master.zip
nginx-1.17.6.tar.gz
安装nginx
安装源码编译工具包，nginx依赖包
yum -y install make gcc openssl openssl-devel pcre-devel zlib zlib-devel进入nginx解压后的目录
cd nginx-1.17.6
./configure
make && make install
使用正向代理https的模块
查看nginx-1.17.6对应的https模块的具体位置
ls /root/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_1018.patch导入模块，再次编译安装
patch -p1 < /root/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_1018.patch
./configure --add-module=/root/ngx_http_proxy_connect_module
make && make install
配置正向代理
nginx默认安装在/usr/local/nginx/
cd /usr/local/nginx/修改配置文件
vim conf/nginx.conf 在 #gzip on; 下添加配置
#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_namelocalhost;
#正向代理转发http请求
location / {
proxy_pass http://$host$request_uri;
proxy_set_header HOST $host;
proxy_buffers 256 4k;
proxy_max_temp_file_size 0k;
proxy_connect_timeout 30;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_next_upstream errortimeout invalid_header http_502;
}
}
#正向代理转发https请求
server {
#指定DNS服务器IP地址
resolver 114.114.114.114;
#监听443端口，https默认端口443
listen 443;
#正向代理转发https请求
proxy_connect;
proxy_connect_allow 443 563;
proxy_connect_connect_timeout10s;
proxy_connect_read_timeout 10s;
proxy_connect_send_timeout 10s;
location / {
proxy_pass http://$host;
proxy_set_header Host $host;
}
}检查配置文件是否有错误sbin/nginx -t
创建nginx用户，用来运行nginx
useradd nginx启动服务
sbin/nginx
