nginx http 轉 https

 先記錄一下

server {
    listen 80;
    server_name example.com;
    return 301 https://$host$request_uri;
}
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    ssl_certificate /etc/nginx/ssl/example.com.crt;
    ssl_certificate_key /etc/nginx/ssl/example.com.key;

    server_name example.com;
}
