nginx配置 http 强制跳转 https 方法

一、最常用的方法：rewrite 方法

将所有 http 请求通过 rewrite 重定向到 https 即可

nginx.conf 配置文件：

server {  
    listen  80;
    server_name www.test.com;

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

server {
	listen 443 ssl;
	server_name www.test.com;
	index index.html index.htm;
	access_log  /var/log/nginx/docs.log  main;
	ssl on;
	ssl_certificate /etc/ssl/docs.20150509.cn.crt;
	ssl_certificate_key  /etc/ssl/docs.20150509.cn.key;
	error_page 404 /404.html;
	location / {
 		root /var/www/html/docs;
	}
}

二、利用 index.html 的 meta 刷新，来实现 http 向 https 的跳转：

index.html 文件内容：

<html>  
	<meta http-equiv="refresh" content="0;url=https://www.test.com/">
</html>

nginx.conf 配置文件：

server {
	listen 80;
	server_name www.test.com;

location / {
    # 将 index.html 文件放到下面的目录下
    root /var/www/html/refresh/;
	}
}

server {
	listen 443 ssl;
	server_name www.test.com;
	index index.html index.htm;
	access_log  /var/log/nginx/docs.log  main;
	ssl on;
	ssl_certificate /etc/ssl/docs.20150509.cn.crt;
	ssl_certificate_key  /etc/ssl/docs.20150509.cn.key;
	error_page 404 /404.html;

	location / {
 		root /var/www/html/docs;
	}
}
