问题描述

The plain HTTP request was sent to HTTPS port

当访问用http时则报错。用https时不报错。
检查配置：

server {
    listen 80 ssl;
    server_name hngj.zxynyxxx.cn;
    ssl_certificate /usr/local/nginx/cert/hngj.zxynyxxx.cn.pem;
    ssl_certificate_key /usr/local/nginx/cert/hngj.zxynyxxx.cn.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    try_files $uri /index.html;
    charset utf-8;
    gzip on; 
    其他配置略
}

解决办法

修改“listen 80 ssl；”为“listen 80 ；”
增加 “listen 443 ssl；”
这样Nginx就可以同时处理HTTP请求和HTTPS请求了。

配置参考如图：

server {
    listen 80 ;
    listen 443 ssl;
    server_name hngj.zxynyxxx.cn;
    ssl_certificate /usr/local/nginx/cert/hngj.zxynyxxx.cn.pem;
    ssl_certificate_key /usr/local/nginx/cert/hngj.zxynyxxx.cn.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    try_files $uri /index.html;
    charset utf-8;
    gzip on; 
    其他配置略
}
