Nginx配置访问http时自动跳转到https

随着技术的发展，以及浏览器的要求，越来越多的http站点开始转为https。为保证原来用户收藏的http站点能继续使用，需要在访问http时，自动跳转到https。
前端Nginx支持https即可，后端服务可继续使用http。
修改nginx.conf

upstream www.nowfox.com{
    server 127.0.0.1:9010;
}

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

server {
    listen 443;
    server_name www.nowfox.com;
    ssl on;
    ssl_certificate   /data/cert/www.pem;
    ssl_certificate_key  /data/cert/www.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    location / {
        proxy_pass http://www.nowfox.com;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/local/nginx/html;
    }
}

然后刷新配置文件sudo /usr/local/nginx/sbin/nginx -s reload
