nginx 80端口重定向到443端口，也就是http访问自动跳转到https

配置如下：

一、修改nginx.conf 配置文件

server {
    listen 80;
    server_name www.域名.com;
    rewrite ^(.*)$ https://${server_name}$1 permanent; 
}

server {
    listen 443;
    server_name www.域名.com;
    root /home/wwwroot;
    ssl on;
    ssl_certificate /etc/nginx/certs/server.crt;
    ssl_certificate_key /etc/nginx/certs/server.key;
    ....
}

二、重启nginx

cd /usr/local/nginx/sbin
./nginx -t
./nginx -s reload
