将amazon ec2 nodejs实例重定向到HTTPS

Question

我正在一个亚马逊ec2实例上运行一个节点/快递应用程序，没有负载均衡器，免费层。我试着把所有的东西都转到HTTPS。到目前为止，我所做的一切都是通过EB CLI完成的(eb部署、eb ssh等等)。

我从letsencrypt (certbot)获得了一个免费证书，我已经设置了nginx.conf，如本教程中所解释的那样。我能够访问应用程序URL的http和https版本。http检索我的nodejs应用程序，但是https返回默认的nginx页面(从/usr/share/nginx/ html )。

我只想在HTTPS上获得我的nodejs应用程序，并将所有HTTP请求重定向到HTTPS。

我的nginx.conf如下：

# Elastic Beanstalk managed configuration file
# Some configuration of nginx can be by placing files in /etc/nginx/conf.d
# using Configuration Files.
# http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html
#
# Modifications of nginx.conf can be performed using container_commands to modify the staged version
# located in /tmp/deployment/config/etc#nginx#nginx.conf

# Elastic_Beanstalk

要重新路由端口，可以在EC2实例中添加iptables路由，例如：

sudo iptables -t nat -A PREROUTING -p tcp -dport 80 -j重定向到端口443

*确保在EC2安全组中，入站HTTP端口80源= "Anywhere“。

若要查看iptables路由条目，请运行：

数多页表-t nat -L

如果需要删除路由条目(第一行)，请运行：

数多页表-t nat -D PREROUTING 1
