nginx配置https转http&wss转ws

前言

安装软件

• 下载

yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
wget http://nginx.org/download/nginx-1.17.5.tar.gz
tar -xzvf nginx-1.17.5.tar.gz
cd nginx-1.17.5

• 配置nginx

./configure --prefix=/usr/local/nginx --sbin-path=/usr/bin/nginx --with-http_ssl_module --with-http_realip_module --with-http_sub_module --with-stream --with-http_stub_status_module

./configure --help 可以查看配置项说明
完成之后的配置文件见：/usr/local/nginx/conf/nginx.conf，参数配置说明：https://nginx.org/en/docs/configure.html

• 编译

make && make install

• 修改配置文件
