如何让Elastic Beanstalk nginx支持的代理服务器从HTTP自动重定向到HTTPS？

Question

我有一个Node.js支持的网站,我在Amazon Elastic Beanstalk上运行.

我的Node.js应用程序侦听端口8080,我在我的EB应用程序中使用nginx弹性负载均衡器配置,在端口80和443上侦听HTTP和HTTPS.

但是,我只想接受通过HTTPS发送的应用中的流量.

我可以在应用程序中安装一些东西来解决这个问题,但是我有兴趣让负载均衡器通过HTTPS将所有HTTP请求重定向到我的站点.

Answer 1

经过亚马逊付费支持的几次虚假启动后,他们最终确实通过了.您可以通过以下方式配置环境以响应端口80和443.然后在主Node.js应用程序文件夹中创建一个名为的文件夹.ebextensions,并在其中放置一个名为的文件00_nginx_https_rw.config,并将此文本作为内容:

files:
  "/tmp/45_nginx_https_rw.sh":
    owner: root
    group: root
    mode: "000644"
    content: |
      #! /bin/bash

      CONFIGURED=`grep -c "return 301 https" /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf`

      if [ $CONFIGURED = 0 ]
        then
          sed -i '/listen 8080;/a \    if ($http_x_forwarded_proto = "http") { return 301 https://$host$request_uri; }\n' /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf
          logger -t nginx_rw "https rewrite rules added"
          exit 0
        else
          logger -t nginx_rw "https rewrite rules already set"
          exit 0
      fi

container_commands:
  00_appdeploy_rewrite_hook:
    command: cp -v /tmp/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/appdeploy/enact
  01_configdeploy_rewrite_hook:
    command: cp -v /tmp/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact
  02_rewrite_hook_perms:
    command: chmod 755 /opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh
  03_rewrite_hook_ownership:
    command: chown root:users /opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh

亚马逊的支持团队解释说:这个配置创建了一个部署钩子,它将重写规则添加到/etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf.

(之前他们曾经提供过.config,它将单独的文件复制到/etc/nginx/conf.d中,但是由于某种原因,这些文件要么没有效果,要么更糟糕,似乎覆盖或优先于默认的nginx配置.)

如果您想要撤消此操作,即删除挂钩,则需要删除此ebextension并发出命令以删除它创建的文件.您可以手动执行此操作,也可以通过临时安装的ebextensions命令执行此操作:

/opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh
/opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh

我没有试过这个,但可能这样的东西可以删除它们并撤消这个改变:

container_commands:
  00_undochange:
    command: rm /opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh
  01_undochange:
    command: rm /opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh

希望这可以在将来帮助别人.

Answer 2

接受的答案对我来说不再适用.默认端口是另一个端口.此外,配置文件的位置已更改.我正在使用Puma设置Ruby On Rails应用程序.

我谈到付费支持,我们通过在运行的实例上手动运行命令来解决这个问题.然后我能够找出以下解决方案.只需登录并重新启动nginx即可.

files:
  "/tmp/45_nginx_https_rw.sh":
    owner: root
    group: root
    mode: "000644"
    content: |
      #! /bin/bash

      CONFIGURED=`grep -c "return 301 https" /opt/elasticbeanstalk/support/conf/webapp_healthd.conf`

      if [ $CONFIGURED = 0 ]
        then
          sed -i '/listen 80;/a \    if ($http_x_forwarded_proto = "http") { return 301 https://$host$request_uri; }\n' /opt/elasticbeanstalk/support/conf/webapp_healthd.conf
          logger -t nginx_rw "https rewrite rules added"
          exit 0
        else
          logger -t nginx_rw "https rewrite rules already set"
          exit 0
      fi

container_commands:
  00_appdeploy_rewrite_hook:
    command: cp -v /tmp/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/appdeploy/enact
  01_configdeploy_rewrite_hook:
    command: cp -v /tmp/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact
  02_rewrite_hook_perms:
    command: chmod 755 /opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh
  03_rewrite_hook_ownership:
    command: chown root:users /opt/elasticbeanstalk/hooks/appdeploy/enact/45_nginx_https_rw.sh /opt/elasticbeanstalk/hooks/configdeploy/enact/45_nginx_https_rw.sh

请注意我是如何更改端口号和配置文件的位置的.

Answer 3

您可以通过Node.js应用程序处理重定向.

亚马逊发送的X-Forwarded-Proto标头等于http客户端不安全连接的时间.

应在初始化之后Express和定义路由之前立即插入以下中间件,以自动将客户端重定向到相应的HTTPS端点:

// Redirect to HTTPS
app.use(function (req, res, next) {
    // Insecure request?
    if (req.get('x-forwarded-proto') == 'http') {
        // Redirect to https://
        return res.redirect('https://' + req.get('host') + req.url);
    }

    next();
});

Answer 4

我能够通过一个稍微简单的解决方案来解决这个问题.

请注意,这是一个部署了SINGLE实例的弹性beanstalk,没有加载balenced.

这是我添加的ebextension.

files:
  "/etc/nginx/conf.d/000_my_config.conf":
    mode: "000755"
    owner: root
    owner: root
    content: |
      server {
          listen 8080;
          return 301 https://$host$request_uri;
      }

Answer 5

我在AWS Elastic Beanstalk上运行'Ruby2 Puma'环境,可能与上面的配置略有不同.在我的环境中,我需要使用'listen 80'而不是'listen 8080'.
