错误问题

The plain HTTP request was sent to HTTPS port

解决办法，fastcgi_param HTTPS $https if_not_empty 添加这条规则，

server {
    listen 443 ssl; # 注意这条规则
    server_name  my.domain.com;
    fastcgi_param HTTPS $https if_not_empty;
    fastcgi_param HTTPS on;
    ssl_certificate /etc/ssl/certs/your.pem;
    ssl_certificate_key /etc/ssl/private/your.key;
    location / {
        # Your config here...
    }
}
