修改Nginx配置文件

示例一

rewrite ^(.*)$ https://$host$1 permanent;

示例二

适用于 80端口和443 配置在同一个 server{}内

if ($server_port = 80) {
  rewrite ^(.*)$ https://$host$1 permanent;
}

示例三 站点绑定很多域名，只让某个域名跳转:

set $redirect_https 1;
if ($server_port = 80) {
  set $redirect_https "${redirect_https}2";
}
if ($http_host = 'www.exampledemo.com') {
  set $redirect_https "${redirect_https}3";
}
if ($http_host = 'exampledemo.com') {
  set $redirect_https "${redirect_https}3";
}
if ($redirect_https = "123") {
  rewrite ^(.*)$ https://$host$1 permanent;
}

配置示例 配置示例：

server {
listen 80;
server_name www.exampledemo.cn;
rewrite ^ https://$http_host$request_uri? permanent;
}
server {
listen 443;
ssl on;
ssl_certificate /etc/ssl/cacert.pem;
ssl_certificate_key /etc/ssl/privkey.pem;
server_name www.exampledemo.cn;
server_tokens off;
location / {
fastcgi_param HTTPS on;
fastcgi_param HTTP_SCHEME https;
}
}
